Awesome bird!  {:)} {:)} {:)}

Are you sure it can fly for 17-20 mins on a 1.3Ah battery? That's an amazing flight time for a model with KF aerofoil weighing about 500g!  {:)} :thumbsup:

Post by: Nithinraj Kotian on September 12, 2013, 06:34:25 PM
thank you Anjan :hatsoff: yea in new battery you can achieve that much flying time but not in old battery its about only 10-12 minutes.  :banghead:

Congrats Nitin :) Happy that you finally have a well behaved model of your own.

@sanjayrai55 Thank you Sanjay Sir :)

@AnjanBabu I think it'll easily fly for more than half an hour @ less than half throttle. Next time we'll keep track and let you know the exact flight time.

Alright, don't get me wrong, but I reckon the motor needs to consume around 3A to sustain ''powered flight'' for approx. 30mins with a 1.3Ah battery pack. 3A current draw sounds unusually less (to me) for a 9'' prop with the throttle stick at any point, unless it's partially gliding too. Please correct me if I am wrong.

Nonetheless, impressive flight time.  :thumbsup:

I guess I was being too optimistic. The flight time however indeed appeared to be really long. We'll measure next time and document it.
