So Finally done with calculations…
Thanks team members for your efforts…

Thrust
1.Motor with 10
5 prop will provide 6690RPM(approx) at 9.9amp supply.
2.Now 6690RPM=615grams thrust(approx)
3.615 grams thrust is more then enough compared to Aircraft weight(400grams).
4.And running motor on 9.9 amp means running it on 80% efficency=80% throttel.

now
*Total current to be provided by battery
1.Motor=10amp
2.Servos=1.5amp(for best performance) each
here i am using 2 servo(1-ailerons,1-elevator)
so servo(2)=3 amp
3.Reciever(5 channel)=0.06amp

So total current to be provided/drawn by components=13.06 amp

battery provides 66amp constant current.
And have capacity of 2200mah.

*Max flight time=current capacity/total current drawn

so by above data

Max flight time(in hours)=0.168

Therefore

Max flight time(in minutes)=10.10 minutes!!

Also at 8.45Amp(67%throttel) it gives 66120RPM=509.98gram thrust.

So we can range throttel from 67% to 80% for good flying.

so,by above flight time formula Aircraft can be flow for 10.10 to 11.46 minutes.

Steven Reubenstone thanks for appreciation…I just Love to do this and Learning a lot about RC technology…It’s beautifull…How it works…signal processing.,channels,and many more…

And ya Aircraft almost Ready…Just waiting for the Propeller…
Soon will share its photos…
