@ cheluvaraj: your plane looks good in design, and well made.. Thumbs Up Thumbs Up
but I will suggest for a bigger wingspan and lower KV motor...
the motor you shown is okay but keep this design with you and make another trainer model first, learn on that and then go for this..
i have made 2 models before my first successful model and wasted a lot of money..  Bang Head Bang Head Bang Head

I agree with arun. But since u've already built it, try the emax 2822 instead of the 2812. Retails at around 550 INR at RCD. This wil give u better thrust at around 900g with a 3s lipo and 10inch prop. PS - I have 6 of these :-D Cheers!

Thanks Arun and veloci.

The one i have built is not looking that stable. used 2mm caro and its not that stiff. so planning to build another one with 4/5 mm caro.

Before that I would like to try with Arun's design. Waiting for Arun to send the final specs. Smiley

Thanks

Thanks Arun.

I'm confused  Huh?  Roll Eyes  Shocked  to select the motor.

RC Bazaar, they have defined THRUST for every motor.  and the cost varies based on this too. So i assume this  THRUST something to do with total weight. (pl correct me if i'm wrong) .

When I look at the Hobbyking, they do not have this THRUST ? what else I need to check if i have to buy it from HK

Thanks in advance
