Tip, zet je volume wat harder... http://www.rcgroups.com/forums/showthread.php?t=526300 Specs: Neu 15/15/2y motor. No gears. Hacker 135-O-F5B This was only the 2nd prop I've tried. It was a 7.4 X 8 APC Carbon racing. Three EVO 3700's. IE: 9s1P. This is definitely enough duration. The most I've replaced of 3700mah was 2200mah after flying for 7 minutes. Full throttle about 65% of the time. Usually I back it off on downwind then come by us full-on. Oh yea...I'm running a 5-cell receiver pack. I ground tested the rpms and get around 26,000 on a 7.5 X 7.5. I used a inflight data logger and found out it unloads to about 28,000 inflight. Amps start off at around 90 then taper off as speed gets up and level at around 70 amps. There was an earlier post that was just about the elogger data which a lot of people were interested in. It was cool to see what rpm/volts/amps/temps were doing in flight. Overall, I have been really pleased and excited about this airplane. It is still alive and I have flown it 8 times or so.
