Hello guys,
After taking advices from kk iyer sir and sanjay sir,
I have decided to build a 30" blu cub 2 plane from gene bond
Please give me suggestions and remarks
Cutout templates,
@nilharsh,
Did you get raw material and the electronics?
Which motor, esc, prop, battery?
Good going.All the best :thumbsup:
Hello sir,
I haven't bought any electronics please sugges me,
I have used 5mm biofoam for plame
Thanks kiran
Well what is the wing size and what is the weight, I can suggest you electronics.
Hello rcnitesh,
My wing size is 30"
I will check the weight without any electronics and post
And weight without reinforcement and electronics is 95gms
:thumbsup:
Traced out parts on bio foam,
Do you have any electronics with you.
No,
I don't have Any electronics,
I'm buying a hk6ch tx rx and 2× 9g servos.
instead of the hk6ch get the rcb6i you won't regret it.
For servos of this size get smaller 5g ones.
battery get this http://www.rcbazaar.com/products/2461-wolfpack-white-900mah-25c-74v.aspx (http://www.rcbazaar.com/products/2461-wolfpack-white-900mah-25c-74v.aspx)
motor get this http://www.rcbazaar.com/products/2398-avionic-m202820-kv1400-micro-brushless-motor.aspx (http://www.rcbazaar.com/products/2398-avionic-m202820-kv1400-micro-brushless-motor.aspx)
esc get this http://www.rcbazaar.com/products/2443-avionic-white-12amp-esc.aspx (http://www.rcbazaar.com/products/2443-avionic-white-12amp-esc.aspx)
Thanks nitesh,
I'm buying used hk6ch for from 1 member of rcindia
Is there anyone selling used rcb6i
I don't know about the HK or rcb Radio sets, not having any experience of them, but the other products suggested by Nitesh should work fine. Again I don't know how good they are, but I have used Avionic Motors, and they work well as per promised specification. Well researched RCN
Hello nitesh,
What about this
http://rcmumbai.com/index.php/product/cf2822-1200kv-motor-2/ (http://rcmumbai.com/index.php/product/cf2822-1200kv-motor-2/)
Sir
How much flying time should I expect with this motor esc battery combination.
I think that motor on rcmumbai
http://rcmumbai.com/index.php/product/cf2822-1200kv-motor-2/ (http://rcmumbai.com/index.php/product/cf2822-1200kv-motor-2/)
Uses more power,
Therefore buying the setup suggested by rcnitesh,
Thanks nitesh.
How much flying time should I expect with abovementioned combination.
Sorry everybody I forgot to put the link,

;D now Back to work,
The instructions on the thread said to put a weight on the parts,
So was doing just that ;D
I would like to ask one thing to experts,
the design of this plane was few years back, so motor mount in template is for geared dc motor ,
How should I make a motor mount for the brushless motor,
One more, can I use cycle spokes for reinforcement...
@nilharsh
Like this:
Three samples.
I doubt if you will need cycle spoke reinforcement. For what? Wings?
Yes sir for wings.
@nilharsh
Pl post pics of side view and top view of wing
Edit: and front view!
Next 2 pics are of real one .
Wanted to see if wing has
1. Camber
2. Dihedral
Going flying now!
Will respond after 7pm.
Sir unable to post pictures here,
They say can't post more than 200kb
No there is no dihedral,
Flat only airfoil.
:thumbsup: :thumbsup: Go ahead.
Then you may need to cut two grooves at say 3" and 6" from LE, and glue in bamboo skeewers like these (kabab seekh!)
Iyer sir mailing you pics
Hello which airfoil should I use,
Template says that bend the wing with heating,
You can bend the airfoil
Yes, you can bend using heating.Even flat wings will work but dihedral wing can handle wind better!
Thank you guys,
Wing bended
Is that enough
Hinges done ;)
No you need to bend more.
Ok thanks,
Does anyone has a used rx tx,
I don't have enough budget now so buying used one,
Only rx will also do.
which make RX are you looking for ? and did you cut 45deg bevel on the control surfaces ? cannot see clearly in the picture.
"Wing bended. Is that enough." "No, you have to bend more"
Come on guys, you are supposed to be aeromodellers. What kind of talk is that?
Simply: Bend one side of the wing to an angle of ..... degrees
Or create the dihedral by laying the wing flat and lifting one half to a height of ..... mm above the level

First model
Sanjay sir you can't call me a modeller can you
Nowhere cocompared to you.
BTW from bend it more I meant to simply make it more underca mbered.
RCRN:
You are a modeller. A budding one, but nonetheless a modeller 8)
will the below one do or looking for a much lower priced Rx ?

Thank you Sanjay Sir, But I don't consider myself a full modeller.
You mean like a half-cooked egg? Functional, but runny at the edges :rofl: :rofl: :rofl:
Half cooked roti.
I am a veg.
Hello sahil sir,
Didn't understand bevel
I followed this video,
http://m.youtube.com/watch?v=-e078oP-gNM (http://m.youtube.com/watch?v=-e078oP-gNM)
And it's working properly
:giggle:
Nice one nitesh
And compared to sanjay sir and nitesh sir iam only wheat dough :giggle:
I too am veg
I am not even 15 no sir.
What !!!?? :o
Then you are a very good modeller,
And my earlier statement is true,
Salute :salute:
I just assembled the plane, not permanently only with tape
parts fitting perfectly, ;D
Waiting for my pocket money, :giggle:
Working on floats till then,
Ps .nitesh I'm 17
And nitesh has posted post no. 50
Yahoo
Weight is 120g now,
With reinforcements on wing
The plane is looking good :thumbsup: I cant't help with the technical details since I am a multirotor guy but I am considering this for my first plane. Would love to see a flight video when you fly it.
Thank you sir
Please don't call me sir. I am even younger than you. I am 15.
What another!!!??
15yr old :o
Hey..!
Nice build :D
Would like to see your maiden video
Plz upload it on YouTube when u do flight test ;)
Anyway
I am 15 too ;) :D
Now I'm getting used to all 15s ;)
But this is shocking there are too many 15s :o
Hello can I use this motor
http://rcmumbai.com/index.php/product/cf2812-1534kv-motor/ (http://rcmumbai.com/index.php/product/cf2812-1534kv-motor/)
Or
http://rcmumbai.com/index.php/product/cf2822-1200kv-motor-2/ (http://rcmumbai.com/index.php/product/cf2822-1200kv-motor-2/)
With 20amps esc
Too powerful for this model.
You won't need more than 30-40 watts.
Thank you sir
Will buy esc and motor combination suggested by you.
How much flying time should I get with 1000mah battery and this combination,
http://hobbysea.com/products.php?511&cPath=43&sid=590ce36248badc1caba93988ac2d2922 (http://hobbysea.com/products.php?511&cPath=43&sid=590ce36248badc1caba93988ac2d2922)
Also connector is xt60 so I need a battery with xt60
You don't necessarily need a battery with XT60. You could solder an XT60 connector onto your battery (risky, BE VERY CAREFUL). Otherwise, you could get an XT60 to Deans adapter like this (http://www.quadkopters.com/product/lipo-chargers-accessories/xt60-female-to-deans-male-connector/ (http://www.quadkopters.com/product/lipo-chargers-accessories/xt60-female-to-deans-male-connector/)) or make one yourself.
Which connector does this battery has
http://www.rcbazaar.com/products/2463-wolfpack-white-1300mah-25c-74v.aspx (http://www.rcbazaar.com/products/2463-wolfpack-white-1300mah-25c-74v.aspx)
its a JST type connector.
http://forum.modelarji.com/viewtopic.php?f=7&t=87352 (http://forum.modelarji.com/viewtopic.php?f=7&t=87352)
QuoteB1 - Deans (T) type main connector - Female & Male. Used for main connection to speed controllers and motors. Used for medium to high current draw
B2 - JST / BEC type main connector - Female & Male. Used for main connection to speed controllers and motors. Used for low current draw
B3 - Tamiya main battery plug usually used on Car and Boat batteries (NiCd / NiMh) - Female & Male
B4 - Bullet Connectors - Female & Male. Single wire connectors, available in a range of different sizes to suit current draw / load requirements from 2mm to 8mm
B5 - HXT Connectors - Female & Male. Available in 3.5mm and 4.00mm sizes. Used for main battery connectors for medium / high power applications
B6 - Traxxas Connectors - Male & Female. Mainly used on high current draw car and boat batteries
B7 - XT60 Connectors - Male & Female. Used for high current draw battery connections
B8 - EC3 Connectors - Male & Female. Used for high current draw battery connections
B9 - Flight Power / Thunder Power (FP / TP) LiPo Balance Charger plug - Female & Male
B10 - Hyperion / PolyQuest (HP / PQ) LiPo Balance Charger plug - Female & Male
B11 - JST-XHR (XH) LiPo Balance Charger plug - Female & Male
B12 - JST-EHR (EH) LiPo Balance Charger plug - Female & Male
Thank you very much sahil {:)}
But I am buying esc with xt60 ,
What should I do now :).
that setup looks too powerfull to me.
dude, don't be confused with connectors, you can change it in to any thing you prefer.
Best way is to get a pack of say at least 10 pair (mail and female) of any type of connector, XT60, or DeansT or anything, and standardize all your power system to that, a few minutes of soldering.
Never done soldering in life man.

Idea is great
Can do soldering from anyone
this is how you learns, btw soldering is a must have skill for electric flyers, master it, you won't regret.
Come on you experienced modellers >:(,
Guide me through my 1st model >:D :P

You want guidance in soldering or modelling ?

Modelling,
You posted reply while I was writing
But there is one thing,
I'm able to contact all modellers through rcindia,
1from kerala other from rajasthan.
How nice.
See the mess I made >:D
Going back to work
I would recommend getting 3.5mm bullet connectors for the motor and esc and ec3 for the battery and esc.
EC3 are same as bullet.
I soldered bullets with ease. (1st time soldering anything) (youtube)
Motor esc is combo,
So do I need to join them
hey, a motor ESC combo don't mean it is pre connected, but some times it may have bullet connectors pre soldered though.
Hello sooraj,
Here it seems that it is pre connected
http://hobbysea.com/products.php?511&cPath=43&sid=590ce36248badc1caba93988ac2d2922 (http://hobbysea.com/products.php?511&cPath=43&sid=590ce36248badc1caba93988ac2d2922)
Is this a esc or a bec,
http://hobbysea.com/products.php?511&cPath=43&sid=590ce36248badc1caba93988ac2d2922 (http://hobbysea.com/products.php?511&cPath=43&sid=590ce36248badc1caba93988ac2d2922)
Most ESCs these days have an integrated BEC. The red and black wires of the servo type lead that come out of the ESC make up the BEC. It seems that you should do some reading on electronics. I would recommend this:
http://www.instructables.com/id/The-Complete-Guide-to-RC-Electronics/ (http://www.instructables.com/id/The-Complete-Guide-to-RC-Electronics/)
yeah, your HK donkey seems, comes fully paired !!
Thanks
who suggested this power system?
Iyer sir,
Why is anything wrong with this
My phone number
8446203709
I'm on whatsapp
No, nothing. jus' asked, But the setup is some what in costly side, what are the alternative motors that can be used ?

But 635 motor and 695 esc is 1330
And I have to buy bullet connectors
And combo comes for 1116

@nilharsh
@sooraj.palakkad
There have been reports that the Donkey breaks its mounts in a crash, but we have yet to experience.
I was using in my Indore Bipe.
Devashish (forum member) has one in his small 3D, and has done over 100 flights with no problem.
Both of us happy with the Donkey 2204 combo.
Incidentally, probably the least expensive...
Emax CF2822 1200kv is available for around Rs 500 (excellent value), but a 25-30amp esc will be required.
Choices are many - one has to start somewhere!
Would have suggested this (see pic) but does not seem to be available any more.
(My test showed 225gms thrust at 8100rpm on 8x4 black plastic prop, drawing 5amps/40watts on 2s 1300mah lipo at full throttle. Cost about 750 in 2012)
Iyer sir, I only suggested that because, if he is not on a urgent build, he can get these motors,
http://www.ebay.com/itm/151495041905?_trksid=p2060778.m1438.l2649&ssPageName=STRK%3AMEBIDX%3AIT (http://www.ebay.com/itm/151495041905?_trksid=p2060778.m1438.l2649&ssPageName=STRK%3AMEBIDX%3AIT)
and these ESC:
http://www.ebay.com/itm/D589-EZ-20A-ESC-BEC-2A-for-RC-Airplane-Aircraft-Multicopter-/371203020022?pt=Radio_Control_Parts_Accessories&hash=item566d6c94f6 (http://www.ebay.com/itm/D589-EZ-20A-ESC-BEC-2A-for-RC-Airplane-Aircraft-Multicopter-/371203020022?pt=Radio_Control_Parts_Accessories&hash=item566d6c94f6)
Have no experience of ebay :(
Cost seems to be USD 1 each for motor and Esc.
Plus shipping USD 7 for motor and USD 6 for Esc :headscratch:
The parts are dirt cheap on ebay , Iyer sir, I bought all my parts for the quadcopter from Ebay, (you can find details in the build thread).
If one is lucky enough, can get really cool deals by bidding,
Like, This : http://www.ebay.com/itm/390977798344?_trksid=p2060778.m2750.l2649&ssPageName=STRK%3AMEBIDX%3AIT (http://www.ebay.com/itm/390977798344?_trksid=p2060778.m2750.l2649&ssPageName=STRK%3AMEBIDX%3AIT)
I got those 4ESC by bidding, but now don't have money to buy it, will do in some days,But problem is I don't need all, looking for partners to buy !!!
And also , I got 4x 2212/13T 1000Kv motors for 25$ and free shipping !!!
@nilharsh,
Regarding connectors:
I would NOT recommend soldering connectors to a lipo to a newcomer to the hobby.
One small mistake and poof. Min damage - dead lipo, max damage - explosion!
As you progress to bigger motors, you'll need to shift to XT60s, as many batteries, esp HK, now have them
But for your present low power need, JST (Rs 15 a pair) is enough.
Yesterday i got a Turnigy 2s 1500mah 25-35C for Rs 550 from Adiboy. It has a JST.
So i am going to put a JST on the Esc (same Esc as in Donkey 2204 combo)
BTW, beyond a point more discussion leads to potentially more confusion.
So just go ahead and make a decision based on suitability, availability, time frame and price.
Best of luck.

Well said :thumbsup:
@nilharsh,
I fear that my last post has made you stop posting.
The purpose was to stop talking and start building/flying.
My sister from Pune is here and returning on Monday.
If you tell me what electronics you have already got, i could lend you the rest for a week or two.
Use it for testing / test flying.
Anything you damage, you can replace/ pay for, rest you can return after a few days.
This is what i do with local newcomers, never before with outstation candidates!
Regards
+1 Iyer sir!
Yup +1 iyer sir. {:)} :salute:
Thank you so much sir
I had to complete some important project submissions in my college so I didn't have time to post reply or buy anything.
Also I paid my pocket money for my college fees so I didn't have money to electronics.
So I thought I put it on hold.
But since you are helping me I will complete the build.
Now I don't have any of electronics not even tx rx but if you're lending me I'm forever grateful to you
Thank you very much sir.
I didn't expect you to help from way back indore, you're GREAT,
@ Iyer sir, +1
@Nilharsh, you are lucky dude !
Yes sooraj,
I'm very lucky.
I thought that I have to hold the build.
I didn't expect iyer sir to help me so much
And thank you iyer for trusting me
@nilharsh
40w motor for 2s lipo, new 10amp ESC, and two new HXT900 servos reached Pune.
Contact my nephew. See sms for phone number.
Strongly recommend you seek help from local flyers.
I understand people fly near Panhard Club (near RC Bazaar).
If you want professional guidance, contact Shri Sandeep Bajare (sbajare on this forum). Don't know his fee, but have seen his trainees fly successfully. Safest option, instead of diving into the deep end without any instructions. (They fly near AFMC)
Thank you so much iyer sir
Forever grateful to you :salute: :salute:
Will expect return in Jan, ok? ;D
Yes sir!
Pm iyer sir
Dihedral
Wing in the pic below is 30" span, has about 6cm under each tip.
This is too much for you, 3-4cm under each tip enough.
The wing has slight undercamber like yours, about 3mm concave on the bottom.
Mark centre of leading and trailing edges. Connect with a pencil line. Ensure 90deg to LE.
Cut the wing into two.
Prepare a sanding block by sticking sandpaper to a piece of wood or a foot ruler with gum or rubber solution. Use fine sandpaper, number 120 or more.
Hold the freshly cut edge of the wing along the edge of a table/glass pane.
Sand a very slight tilt. Alternatively hold the wing with the tip supported about 3 cm up and sand the edge vertical.
Repeat on other wing half.
Must use a sanding block. Freehand not accurate enough.
Ensure that the edges match. Tape them together at the bottom.
When kept flat a groove will be visible on the top.
Lift one wing to ensure that the groove closes neatly.
Open the gap and apply Araldite Clear 5min epoxy. Close gap and hold.
I dont think hot glue is good enough for this joint.
Edit: Pics attached
Pic?
Okay sire,
Understood at last after reading 3 times. :P
Will do the same. :thumbsup:
I wonder will araldite would be enough to hold the wings together. :headscratch:
What else do I use for reinforcement
Pics not loading.
Will try after a while.
Edit: Funny. Pics loaded while i was typing this!
Is that mini quad in background
Funny indeed
Same happened with me once
Do not exceed 280gms for this size wing.
Araldite joint should be enough.
Caution:
Motor is 5amp, 40watt with 8x4 prop on 2s lipo.
A 3s lipo or a prop larger than 8x4 will burn the motor in 1-2 minutes.
(Yes, Intruder. From Hellyflyer. Rs 1700)
So no spars and cf rods?
I think that the weight will exceed 280g
Because the floats are still ro be added
Forget floats.
Forget undercarriage.
Have you learnt to fly yet?
Flying off water is far in the future.
Please do not be toooo ambitious.
Initial objective has to be to get airborne, do a circuit and land safely. On GRASS.
This motor will not be enough to fly off water.
Don't complicate your life too much.
Learn to fly first (with someone else doing the takeoff and landing)
Then take off and landing.
After that you can think about water.
Do you realise that your entire investment can SINK in a few seconds?
Have you tried to do a flight on a simulator?
I fear you are underestimating what is involved.
Have you been to Panhard or Ram Tekdi to see others flying?
Ok sir will do as you said.
I underestimated it rc flying.
First will take help of local flyers
At first I thought that the flying from water is easier than land
Practise on simulator or take help of someone, if you are flying for first time. :)
Will be visiting pancard area on Saturday and Sunday.
The wing dihedral done.
Will upload pics after some time
Hello fellas,
Work going ahead (though at a slow speed ;D)
1. Motor mounted
2. Control horns installed (home made , they are good and hard)
3. Assembly going on in final stage
I have installed a servo on upper side
What do you think of it?
All servos and motor and esc, thanks to iyer sir
1 question,
I installed a control horn for elevator here ,see pic
Should it cause any problems for me aerodynamically
Or should I change the position.
I tried to change the position but, it's not moving,
I'll have to cut it down....
@nilharsh
Instal a new one closer to fuselage side. (This one can remain, or cut it off)
Looking good so far.
But replace rudder push rod with slightly longer one so that the servo arm is perpendicular to the rod.
Else you will have unequal movement on either side.
Ok sir,
Changing rudder push rod and new control horn for elevator
Ok work moving ahead, :)
I took a test glide of plane.....
:thumbsup:
....And it glided perfectly for 3 to 3.5 meters
