hi all, so long-story short, i making my first tricopter (first flying thing for that matter), i went with the bat-bone and everything the flite test guys listed as recommended, except i got 1600Kv motors instead of the 1380Kv since hobby king was out of them and i hadn't done much research up till that point on airplane motors(I'm used to Ground RCs and normally Kv just mean rotations per volt, i didnt know about prop sizing or anything like that). so 15amp turingy multistars, 1600Kv turnigy park300s, kk2 lcd, and 8 x 4.5 props. so, enough of that here's the problem im having-
one thing i also noticed is it seems like the motor are pulling different amounts, it seems the front left motor pulls up its corner first. in self leveling it less noticeable but still there, without its downright bad, like flip over instantly or needs a bunch of stick input bad. i check the gyros and they were all compensating in the right directions, i tried increasing the p-gain and limit on the self leveling to no avail.
so here are a few of the things i think might have caused it-
funky wiring harness
the male dean in the top corner connect the battery and that goes down to female deans that connect the ESCs. i had no bloody idea how to wire this thing so i winged it, and it kinda shows.
motor to ESC wiring
this is just embarrassing but i didn't have enough bullet connectors. i thought i did, but i didnt. so i soldered the yellows together, and put the bullets on the red and black so i could reverse rotation if i had to.
motor damage
this actually isn't the first tripcopter frame i've tried, i got a cheap Chinese one from a friend so i ordered the electronic stuff and tried to fly it. i still had self leveling problems and ended up crashing it hard, it hit the motor and broke a carbon spar. it seems to spin okay and the shaft dosen't seem bent when i run it up.
i also kinda ordered in haste, i want to FPV with this thing, but i also want to do some filming along the lines of stuff like chasing the cars around the local autocross course. i heard David talking about hobbyking plush ESCs on one of the vids, so at least from what i kinda understand to be able to haul this thing around and change directions fast i would want a lower KV motor and a biggerprop.
anyway, enough rambling on my part thanks in advance for any help i can get, cheers.
