I run a thunderpower 30c 2250mAh on the stock 70mm lx models fan, with the stock motor, and I don't know if you tested it but your plane looks to be gagging for power, excellent flying but the power seems a bit lower and acceleration is much lower than my F-22, and your flight times are a little shorter sucking that kind of power,

Hi, I did not test it with that battery. Yes, the stock motors and fans are usually underpowered.

I'm w/ cruddneck... I think the speed is more of a function of the airplane in this case rather than the fan unit. I thought it looks like it flies great and had plenty of power. Great job flying and landing!

[rolexcomex]

thanks!

[mach7rc]

Great flight, do you have elevator and aileron mixing going on?

[rolexcomex]

Thanks! No mixing. Just low travel since the flying surfaces are so large..

@heychas correct.. I got th retract version of the lx models F-22.. I've upgraded the motor to a 3300kv installed a turnigy 80amp ESC and enlarged the hatch to use a 3000mah 35C (that still comes down puffed when pushing the plane hard) I saw some improvement on the speed and landing speed inscreased too but it's the airframe that limits the speed on that plane.

NICE LANDING

[governmentcheese411]

nice looking plane but if that is 1300 watts then something is way off. my 1500 watt raptor goes vertical from the ground. i mean literally i can just hold it pointed up, throttle and let go, and at 38in W/S and 4.9lbs with retracts and cockpit. probably just needs tuning here and there. did you remove the inlet lip. that,ll help a lot if you duct air in pretty good. good luck

A thrust cone would have helped. I am not sure that by that much but it would have helped.
