Hi Anwar.

I am planning to buy wheels from RCDHAMAKA.
Actually Anwar, the model i have done is for a engine powered, as someone in bangalore was selling a used 1.5cc nitro engine, so i planned to purchase it & made this model, but the engine is not in good condition(very old). So i did not purchase.

But now i have decided to used my brushless motor, but i feel the model will become heavier, i have a "EMAX CF 2822" motor, 30 amps ESC, and 11 v battery(2200 mah), but the problem is the battery is heavy(150 grams). wondering if it will fly with the small wingspan. i will weigh the model tomorrow and keep you all updated.
Please assist.

If anyone has a 1 cc or 1.5 cc used engine, who want to sell, please PM me.

Thanks.

Thanks Sujju,

I am waiting for monokote wing covering, i will order it today from rotor(chennai).
But Sujju as mentioned in earlier post, i think the weight will increase as i have 11v battery which weighs 150grm. anyways i will weigh the model tomorrow & keep u all update.

Hi RC,

Very good design.  {:)}

You mentioned the weight: 700gms. What about if the structure build with coro plast will decrease?

Suppose, to convert the same to electric, which electric motor you choose?

Regards,
Dileep
