RC India

Hello guys ,
                 Im feeling extremely happy to share some experience of my 1st ever built rc plane . So, guys please direct me or correct me , if u find any flaws in my work. I hadn't seen & haven't flown any rc plane before , even kids plane also  :giggle:  :giggle: . Building something which can fly and can be controlled with ur fingures was the dreame of mine . But, after joining rcindia , it is getting converted into reality, so big bigg thanks to rcindia family.  :)  :)  :) .

Here r some pics of my work.

What power system are you using? The motor looks smaller with respect to Propeller in above pics. However I could be wrong.
Tell us about that Custom Prop saver and bottle cap Landing Gear.

Thanks.

Saurab, all the very best! :thumbsup:

Nice build mate!  {:)}
I liked that landing gear too! Like Sumeet said, that prop looks too big for that motor. Which motor and LiPo are you using?

One suggestion for those bottle cap wheels, Try wrapping a thin layer of Foam or something on the wheel (But keep increasing weight in mind). it would prevent the drift on hard surfaces and it will also absorb small shocks during takeoff run.

Nice Video By the way.
Cheers.

hello guys,
              I have used the following power system:

motor:

esc:

battery:
Desire Power, 800mAh, 20c ,2s, 42gms. - from sai sir .

servos:

2- nos.

@sumit: Yes sir , the prop was looking quite heavier for that motor , actually dowell pin provided with that motor was very smaller in length , then i increased its length by screwing the pins of 2 pin socket from both the sides  :)  :) , and it worked for me , n now motor doesn't look small at all while rotating.
I didnt understand what Custom Prop saver means? it is just rubber bands that i hav wounded over the dowell.

@vc: thanks sir .

@swapnil: thanks and the bottle cap idea is not mine, its my mom's idea, full credit goes to her only  :salute:  :salute:

thank u !!!!

- saurab.

sorry forgot to mention the AUW it is 196 gms ~ 200 gms.

@ sumeet : thanks for the nice suggesion .

By the way , i wanto ask in common , what u guys say about my video , does it will fly in the air ? ur replies matters a lot for me, so please ......  :help:

And one more thing , as i hav already mentioned that its my very 1st attempt of holding anything like this , can i take the maiden of it or i need to hav supervision. Im feeling quite scared .


thank u.........!!

Your prop seems bigger than recommended prop size of motor which is 7x3.5 to 8x4
If you are using bigger prop then be sure that motor is not sucking more amps than its rating. Otherwise your might end up in burning of your motor.  Also you will not get maximum performance from your motor if you are using prop other than the range of recommended props.

btw nice plane!!
If you can find any experienced flyer then it will be better as this is your first plane.
Practice on sim, it helps a lot.

Dear Saurab! Don't call me sir even if you are 2 yr old,  :giggle: .

-> You forgot to mention "what propeller are you using?"

-> My mean with that Custom Prop saver was "Whatever you did to make the motor shaft suitable for your needs." Those Dowel pins looks like pulled out of an electric plug, isn't it?

-> One more suggestion, Do a glide test before you actually fly it. Also Check CG twice. If they go correct, Then there is no reason for the plane itself to refuse from flying.

-> Have you ever been flying on Simulator? If no, care to do that first. Or find an RC buddy in your reach which can actually maiden it for you or teach you How to fly.

-> I too ask my mom or sister each and every time when it comes to choose a color scheme on my planes. They are great. And in this case, We are same.  :giggle:

Thanks.

should have given it some dihedral

No its just fine without dihedral also. Does plan includes Dihedral wings?

Saurabh

many congrats on ur first built model,
as forum members suggested prop looks quite big for that motor

go for slow flyer prop 7 inches, and also as a beginner go for dihedral wing

I am a frequent visitor to mumbai, i can meet u one day



prashant

sorry guys for the late rply . Yeah, i actually forgot to mention prop , i hav used 8x4 prop.

As per the motor specs.

Recomended prop: 8040/2S or 7035/3S

So, i have used 2s batt, then 8x4 prop. should be ok , i think ...

@spitfire : I took its hover test 3-4 times, it worked fine , even esc also didnt heat up . 
@Sumeet : Yes boss ! I wll not call u sir frm now after , by the way im 19 yrs old  ;)
                And the dowell pins r not pulled out of an electric plug but actually,as i hav already           told , the pins of the electric plug have screwed up from both sides . And I haven't try on simulator also

Actually , they r great n i also dont like people to call me sir, by the way, I dont deserve for it also ,thats another matter  :giggle:

@dhaksha_dx : The plan included the dihedral , n i also hav given it , by 1 inch from both the sides .
@prashant_rc : Thanks sir , for ur compliment n suggestion , as i have already mentioned , i hav used 8x4 prop. which is within recommended size . And , yes off course we wll meet one day , can u give me ur no. ? here is mine : 9821350821 .


Thanks for all ur replies ......n i'll surely consider all ur suggestions ....  :)  :)

- saurab.

please post a link of electronics which you have used in this plane (with links to buy the please)

pylonplane - did you read the thread ?

links to electronics have already been posted

Hi Saurab

This is prashant

"Boss" is not good either.  ;)

Well If I was you, I would go with a prop smaller than listed. Like prashant_rc said, 7" prop would be enough.

But now as you already have 8x4, run the motor with this prop for few minutes on ground on almost full throttle. Hey but don't pull too much out of that battery, Keep this in mind. Always remember: Battery voltage shouldn't go below 3.7V per cell (ie; 7.4V for 2 cell battery). If the Motor or ESC gets warm or Hot? Go with a smaller prop. Otherwise you can go for maiden.

All the Best.

what was the total cost for building this plane?excluding tx and rx  :salute:

@prashant_rc : thanks sir , I hav noted down ur no.  :)
@Sumeet : thanks sir , for ur great suggestion , n i'll definitely think abt that 7" prop. But can u tell me the exact size like 7x2 or else...?
@pylonplane : As saikat sir hav told , the links hav already posted n if u ask me abt the cost , then u should sum up all the price frm those links , it may be around 3.5k- 4k , bt y r u asking such questions? search on the forum , u will get everything here, like me as a beginner have got everything frm zero .

thank u ....!!

- saurab.

The most common size 7" props are SF E prop 7x4, 7x5, and there are some GWS DD 7035 props also. Search on HK. You will find.

Thanks.

thanks sumeet , I'll think of it .





thank u..... !!!

- saurab.

Hi to all, as per suggestions has come out frm u regarding the prop size , im planning to use the smaller one

wat u guys say abt this ? :

http://www.rcbazaar.com/products/1222-7x35-direct-drive.aspx

or else plz suggest me some other options n do tell me if u hav any.... with u in spare. 


Thank u ......!!

- saurab.

Just try it. 7x3.5 seems good match for your motor.

Thanks.

Great attempt for first rc model...model is good looking..i tink as all mentioned the prop is heavier for model...and also my suggestion try give some extra length after wing portion fuse to tail...it ill be better for good flying..

Saurab,

Are you using depron in this plane ??

@Sumeet : Thankss... fr ur reply .
@bhanuflying : thnx for the compliment, but I didn't understand wat exactly does it mean "try give some extra length after wing portion fuse to tail"
@gbisht : Yes , it is depron only .

Thank u ....!!

- saurab.

nice build,
done flight ???

I mean increase the length of fuselage some what ...in your model that means what i seen in video i noticed wing and tail are nearby so after the wing the length of fuse should be given that means distance between wing and tail ....should be proportionate...that means both should be separated fairly in a distance so that u can achive good control.

@bhanuflying : yeah , i got it , i'll surely keep this in mind , thanks ....
@gbisht : No maiden yet , waiting for pair of props. to come, thnx by d way..... :)

Thank u ....!!

hi saurab the ground test video of the blubaby 24" taken yesterday





Subbu

thanks for the help Pikle6......... no matter it crashed in maiden flight...... but i learnt lots of thing frm it  :) we'll definitely meet once again with bigger version of blu baby i.e. 33"

n thanks for the video too...  :hatsoff:

- saurab.

can we see the flight video?

coderbanana we did not take the video of its flight (which was very brief) even at full throttle the wind was toying with the 200-250gm aircraft and less than a minute after launch the plane spun and dived out of control and the rudder was not enough to rescue the plane so i cut the throttle before the crash other than the motor mount nothing was even hurt. i was surprised to see the propeller too was intact.

hey saurab i have an idea fix the nose of the plane and bring it to my place lets fly it indoors somewhere that should be great for that aircraft and also how is your simulator training going on. if you have any troubles building the bigger blu baby come over to my place we willl finish it up together as of now i am building my V22 osprey.
