I have made a plane with complete two 8mm  depron sheets but this becomes heavier

Can anyone tell me the specification of motor esc i need for plane?
Weight of plane - 240gms

I also need a 6x4 propeller but i am not gettng it from anywhere

prop:

motor (will give thrust of 500 gm. if used with 6x4.  suited only for small 100-500gm parkflyers)

a pic of the plane needed..

The space in the centre is only 6 inch so bigger propeller will not fit

wont this do??
its 6 inch

Is 1200 kv motor not small for plane because after including electronics this becomes about 500gms

Ask that from somebody experienced. I donno

Thanks

I think you need to widen the space in the centre
Cause 1200 kv motor with 6 inch props... lot of thrust waste
Bigger props give more thrust (depends on the quality and type of the motor)
Look out for a suitable prop for that motor

If i increase the motor power to 1800kv and use prop of 6x4 is it works..??

I don't think a 1800 kv motor will give enough thrust to lift 500 gms with 6 inch prop. I believe you have to increase the size of your prop.

Ok i will use 8x4 thankyou so much

Hi,
If you have no prior RC flying experience, this may not be a suitable model to start with. Better to start with a Skysurfer or similar (RC Bazaar).
Pl see your PM. have sent more info.
Regards

But sir  i have started this model and its almost to complete i only need a motor and a propeller.could you tell me prop and motor for this model..??

@suyash,
Last month Col Sundaram's son built and flew a model similar to yours.
Send him a pm (param on this forum).
His build log is here:

Hope this helps!

Thank you sir

@suyash,
See this:

Is this because of weight or motor power..?

You need a high KV one with lot of speed than thrust.
CF 2522 will give max thrust at 10 inch prop.
https://www.rcsportz.com/index.php?route=product/product&path=70_80&product_id=98

this one is lighter and gives around 400gms of thrust plus 3 blade 5inch prop will give you good speed on a 3S lipo maybe less than 1000mah.

hy,suyash i think that is an rc powers f-18 v3 ?i also made one for this year sweepstakes i used 2300kv emax 2826 motor with 6×4apc and 30amp esc with 2200mah li po 3s

Yeah i m trying to make f18 v3 but i have 1800 kv motor.

@suyash,
Did you read the post about how much power?
If your motor is lower kv, all you have to do is use a higher pitch, like 6x6 or 7x6.
Please post the ID of your motor, to suggest prop size.

I have 1500 mah 20c lipo
30 a esc
6x4 prop
1800 kv outrunner brushless motor

i think that you should give it a try then, coz you have reduced 60g on battery also and some on motor .launch it at 100perc throttle it will work fine.
