'bout ready to maiden my new H9 Xtra Easy RTF Trainer with Evo .46 engine (11X6 prop) and 11oz, fuel tank. If you have flown this plane please let me know what is the flight time of it under normal circumstances (1/4, 1/3, 1/2, 3/4 throttle). Would hate to have an out-of-fuel dead stick or land 10 times to check the fuel level in the tank. Need an "about time" to set as low limit on timer.
Thanks.

About 20 minutes at half throttle should be about right.
Set your timer for 15 minutes anyway... that is more than long enough for a flight.
Any more time than that during one flight is too mentally fatiguing and you won't even realize it.

I fly a big stick 40 with a TT .46 Pro... I safely get 10 Minutes out of an 8oz tank... and I am almost always doing vertical full throtle stuff.. just my $.02 I dont even mind dead sticking inverted 3 feet off the ground cause im going 60 mph and i can push up and split S for landing...
