Great going Arun sir.......we'll be up with our build in a day or two, so keep watchin, ;-)

Bilal thanks for that... Want improve my design after watching your's.. I know you are a very good scratch builder and you have already proved it... Waiting eagerly for that beauty... All the best guys..

Before adding weight to nose, adjust battery and electronics board position for CG balancing so that every milligram can be saved.

Sir actually i purposely added the foam in front not only to correct the cg but also to sace the fuce from crash.. now it crashed about 50 times while testing glide and also in throttle.. But no problem with the fuse till now.. The 1 gm of weight is doing his job very nicely..

Sir currently I am controlling the elevator like that only by throttle inc/decr..
Did i missed something? like abhay suggested?(keep the motor 1-2 degrees low)

Good Job. Hope 3rd motor connection will help you for actuator.

@kalyan da: yes sir wan to find out the 3rd motor connection today... Sundaram sir also suggested the same way that you suggested..

QuoteGood job

Thank you sir.. 

yes bro we will do it,you know i alway had a hangar rat kind of model in mind like this http://www.gregcovey.com/hangar_rat.htm AND THIS i also love the way they look and move. have to do some thinking and forum reading 

Check this out Arun bhai,
http://www.rcindia.org/electric-planes/scratch-build-living-room-flyer/msg107396/#msg107396

I build this last year, it flew really well....i too controlled the elevator with throttle and rudder with differential thrust, but since my heli didn't have an onboard gyro hence it flew kinda erratically.......balancing the differential thrust with the trim knob is really difficult,..........but the design was really forgiving and looked great, you can try it, gimme your email I'll mail you the plans

cheers
Bilal

Bilal I had seen this already and thats one of your great work i mentioned earlier..
I found the thrust is bit low when i mounted the motor in pusher config.. I am using micro quad spare props it wont work a pusher props i guess..
Any way mail me the plans let me Try once again..
 

Hey Arun How About this one, use only one motor with gearbox, so that you can use bigger propeller and also the battery will give you more back up even and weight also will be reduced. Because adding two motors in parallel, need more precission, even one gram of weight difference in left wing side with right wing side, it will miss the balance. Correct me if i am wrong.

@kumardasai: Wow what a timing sir just nomw finished making one..
weighs 8 gms including motor prop and gears everything..
But the thrust look more than what i want need to use a smaller prop.. 4030 would be better i think..
Or will go for this itself..

Here is the pic 
bench test done and balanced already.. 

gears from an old wall clock and toy parts works as bearings for prop shaft.. 
Put some grease inside as lubricant.. 

hey and one more thing.....Instead of using the actuator for the elevator, to reduce weight, you just use a slightly up fixed elevator, so that it will work based on the throttle speed. what do you say ? (just 5 to 10 degrees fixed elevator)

Yes that is a great idea thanks for that sir...
But i need to add an actuator for rudder as the turning radius is very big right now... 
Couldn't found the rudder motor connections in the receiver till now... 

yes, it depends on where you fly...if you are flying only indoor then you can also use the same technique for the rudder as well (slightly left or right fixed rudder), so that it will always fly in that direction only (either left or right). If it is out side then the actuator for rudder is mandatory i guess.

Can you just tell me what make/model is that heli ? because i too have some IR helis lying with me in home, but they are having tail motor attached to them. I can give some info if the make/model of your heli matches with my helis make/model.

Arun I am not sure wether you came across this post.

Dear TG,

I am posting photographs of the geared power system driving a 3030 GWS props, fabricated out of the recovered 6mm coreless motor along with pinion and gears from a gear damaged 8 gms servos.

I am also posting photographs of a gear and prop arrangement for a 4mm coreless which I am waiting for.

Video link of the attempted micro alula being tried is also posted under. Thanks for watching.

@sundaram sir: Yes sir i have already gone through this..
Currently i dont have 2 small props in same size thats why didn't go for this..
Can you suggest me a good place to get Small gws props... ? hobbyking have these? 

Arun, check the below link, it may help...

http://www.hobbyking.com/hobbyking/store/__533__265__Hardware_accessories_-GWS_Style_Propellers.html

Sir but Is that the real GWS prop for micro fliers ..
The shaft hole looks too big..
The GWS micro plane props looks a bit different and will be very light weight..

This may work but little costly for a micro flier !!!!!!

http://www.rcbazaar.com/products/1141-uberlite-carbon-fibre-propeller.aspx

Yes they are... Want to check for any other source or alternatives..
Sundaram sir is not using CF props.. Think it is Glass fiber.. Any way its going to be costly..

Check RCdhamaka quad propeller section they had 2010 GWS style CW and counter CW

Sir they have only the 2508 propeller which is what i am currently using..
checked HK all are out of stock..
I think i should go for the Rcbazaar one.. CF prop..

Hey Arun,

Check this one, they are little low in price and i guess they are made up of with thick plastic and little heavy in weight...check with RCBazaar and ask them to give the weight details if possible. Let's first compare the both props weight (carbon fibre and ZT Model prop) and then we can proceed further.

Sir i bought this 2 days before the 7" one.. 
But which is really made for rubber powerd.. which weighs 2gms and also some difficulties while spinning... now trying to cut them and balance it properly..
Nice find sir thanks for that... 

The thing is that My first micro flyer flies good, the difficult part is turning, going out of signal before it gets turned. If i placed the rudder a bit turned it can make circles.. Will upload the video, let me take one..
But in case of the second one the thrust is not enough i think it is because of the prop.. What i am using is the 6030 orange props..
