You can use spray paint for an easy way.... Easily available at car mod shops

@soham  http://edallhobby.com/  they hav 2200mah in stock

Do not go with 2200mah lipo. according to your pics the plane have short wingspan. as it is smaller plane, the 2200 lipo will increase the wing loading. will not fly good.

As this is your first plane try to make it light weight.

Ya ofcourse I will post the pics  ;)  @aman

Thanks @swizera ... so which battery should I prefer ? ???

manojswizera

soham,
any 3cell 800 to 1300 mah lipo, will be fine. Which will not increase the weight.

this will also work.

i would suggest to go for a 30 amps esc....

n battery 1500 mah should be good.

i would suggest to buy 2 batteries .......u dont want to go to field with just 1 battery...

and dont forget the lipo charger if you dont have one..


NOTE: senior forum members please correct me if im wrong.... :salute:

Hello Soham,
Your plane is too good for first attempt. But do not make/ buy electrics for this plane.

First visit some field and see how the RC plane looks like...... your plane needs control surfaces which are not easy to make.....

i would strongly suggest to first see an RC plane ... give it a second try then buy electrics... cause what you have invested on this plane is <2-3% of what you intend to spend on electronics and transmitter.

the aerofoil shape of wings as seen in pic is wrong..... thickest part of wing should be @ ~ 35% of chord from leading edge. Also you are wrong for the weight as well the airframe you have made must be >100 Grms use a weighing scale + a lot more weight is yet to be added... motor mount, control surfaces, landing gear ( if you want safe landings  ;D), servos , control rods etc etc

and for electrics go for <1000Mah battery and a blue wonder motor with 10-12 amp esc.....for a 1200 mm wing span and <500grm plane.

I think spray paint damages theromocol  :headscratch:
Yes, it will eat through when sprayed over naked thermocol. But since you have covered your model with paper, it should be okay.

Patch up any exposed foam, sand it down smooth and spray it over. I've tried it and it works.

Good luck.  :thumbsup:

well by using water,newspaper,fevicol you will be making it very heavy

Hello I am new to this forum .I want to build a rc plane I am having a 1100kv brushless motor.what lipo and esc will best for this?

prabal276

what are the specs of the motor?
without watts,
it can be anywhere from 80 watts to 500 watts. What are the amp ratings?

I don't know .Its Rotobotix 1100kv Brushless Outrunner

Soham, buy 2 bottles of fabric paint ( white and red ). It is very light weight and also shiny when some fevicol is mixed with water at 2:1 ratio of fevicol with water. Then dump this bottle full in that. Then, you will be ready to paint and it will look shiny.

hi i am new on group,
please tell me , u used locally available thermocole or any hi denicity material

The best way to strengthen Thermocol is not to add fevicol and cover with paper, but to cover it with thin plastic food wrap(available in stationary stores) This won't add much weight, make it crash proof (mild) and you can easily spray paint it to your colour choice.

Thermocol lighter than coro. So for a real slow flier, Thermocol or laminated depron is better than coro.
