i just found a really bad blockage in my exhaust extension. Changed it and re-routed the exhaust. but due to the nature of my tuned pipe I have to have the exit pointing out of the left front corner of where the gun is up front. My mistake was trying to have a curved section inside the fuselage so the exhaust would exit the bottom.

heading out now to fly

wow what a difference! lots more power, so it kinda looks like 20mm gun exhaust coming from the left front side of the nose.

so now I have to do the pitch and power curves all over again. Got 2 really good flights in. video to follow.

I have a suggestion though. I think that while doing all your trimming and pitch/power curves you put the stock raptor landing gear (or whatever plastic gear you have) on the helicopter. I've had it settle back in a few times and at 11.5 lbs its a little tough on that aluminum landing gear. The plastic can flex more

well I dont know why this gopro camera kept shutting off. maybe it doesnt like vibes. I had 2 nice long flights, including some fairly moderate forward flight, but this is all the video I have to show for it.
