At last I have discovered the reason for my disastrous foray into the larger and more expensive helicopter. Found the reason today.
It was and is an intermittent fault on the tail servo. What a bummer. It came to light when the heli was about 20 feet off the deck. It
just started spinning like crazy and I thought it was the end. I lowered the throttle and let it come down to about 10 feet and thank
goodness the tail began to work again. I landed no problem. Now the tail servo will not work at all. I tried a new servo in the Brain
fbl unit and it worked perfect so I have a duff rjx tail servo. So there it is. I have stripped the motor to get at the fbl unit and also found
the belt from the motor to the first drive is not running correctly. Just how I fix this I do not know at the moment will have to give this
some thought. What I think was happening when I spooled up the heli the tail servo failed, heli spun tail touched the ground so destroying the
the bevel gear, tail servo started working again so I thought the bevel gear was the fault. You should by now hear me screaming in Iowa lol and across
over to the west and up the Grand Canyon. Bugger1 bugger! bugger.
