Well, that's annoying!
Got the bird fired up today in my studio (way way too windy outside) and got trim set (it was close) tracking was dead on.
FIrst issue was some sort of radio interferance. Yes, on 2.4 something was taking control of the radio, er, receiver. I'd cut power and land and the servos would all be operting like mad....off/on radio and they'd be OK then. Odd. OK, lets spin up again and I could see the swash plate moving around...a LOT too. Odd.Β* I physically moved myself and then had no more problems. Could be position of rx/tx antennas to eachother. Not something I like to see, ever, though.
OK, so now lets practice a bit and see if I can hover it. I'm new, so that means ignorant at some things. It wanted to skate left and forward to trim a touch and it's better, but when I give it right aileron it literally sticks to the ground. What the ? I'd release left aileraon and it would rise and head fwd and left. Hmm...
After a few of these up and wobble, set it down, move it back to the center of the square and I noticed the right aileron servo is not moving. It's frozen in the up postion. Well, that explains a few things, huh?
I had the tail servo seize on me the day I was putting it in..it worked then didn't. Took it apart, checked the gears and grease and it's been working since.Β* I guess I'm gonna be swearing a lot on sunday when I pull all the servos out and go through them (we know what a process it is to get the front ones out. The cheap screws don't make this task any more fun of course. And I did a good thing using screw and nut to hold the servos in...but the screw on the front lower inner side of the servo was zero fun to install (ended up putting a hole in a straw and poking the screw through it as a way to hold it and get it in the hole). The servo will move if IΒ*manually move it, then it jams, work it and it moves again then jams. Something (flashing?) is in the gears.
So I've not got the co-pilot on there yet and there's point with the servo issue. If I'm pulling one to check it I'm pulling them all.
I'm using tPro MG90 servos....what's better (as in reliable?) or is there a 'fix' for these? I'm just unlucky? To see them work then seize (50% failure rate after use) seems way excessive.
