Hey Gary-I tried to call you the other night. I just got a Mega 22/20/2 brushless motor, Hacker Masters 40-3P controller, 5:1 Mega gearbox swinging a 16x10 prop using a 10 cell 3000mAh pack. It's not a cheap setup but it has some mean thrust.
Should probably be using a 18x?. But the landing gear are to short! I've bent mine as far down as possible for prop/ground clearance. I need a longer set of landing gear.
This setup pretty much went straight up after a couple of feet rollout. I kept a bit of up elevator as I started rolling out so it did not catch a wheel and nose over. Well as I increased throttle with the up elevator it just went up and almost over. I eased off the elevator and it just kept climbing.
Unfortunately, the gear box got chunked within a couple of minutes. Not sure what happened. I think maybe one of the planetary gears hung up on the internal spacer washer and this gouged the gearbox back plate. I'm not sure what happened. It sounded like the plane was running on nitro-very loud. I landed pretty darn quick. I'm going to clean up, re-lube and hopefully reuse the gear box.
In the few minutes of flight I had the plane did not self destruct or so I'll keep flying it!
See ya-Scott
