HELP - 8103 Trims went crazy on their own
Hi Danny.
This saturday, I was maidening my EF Yak-54. After proper setup and range check, I did a couple of ground runs.
So far everything is good...
Then I take off, the plane starts to roll to the right and I try to give it left trim...
Now instead of the beep...beep.beep sound I get a "bbbbbbbbbbeeeeeeeeppppppppppp" sound and a/c starts a hard roll to the right and starts diving.
I am fighting the controls now trying to level the plane. At one stage I decide to "let it go". Fortunately, there was no one at the field and I successfuly land the plane.
Upon inspection, all the trims had gone haywire on their own. The aileron trim was all the way to the right, the rudder to the right and the elevator trim was down.
It really freaked me out. I centered all the trims, did another range check and decided to try again. SAME PROBLEM [:@] ...I landed safely again.
What could be the problem ???
TIA.
