ginnz -> What the heck is wrong with my BH 500 se pro? (4/27/2008 11:59:15 PM)

well, last week i broke a mainshaft on the 500, i replaced it, and did a test hover or 3, and it was ok. this afternoon, after a week of 100 mile an hour 24 hr a day winds, i got some relief, it was only gusting to 25 kph... -) (southern manitoba spring always has 40 days of wind!)
anyways, i took out the 500, and after 2 minutes noticed a problem. it seems the elevator sevo had a broken tooth. so, i replaced the servo with an E-Flite S-75 Sub-Micro servo i had kicking around. put it all in and had to make some adjustments, but it all seemed good. i got a good hover, then noticed the tracking off a bit. so i adjusted the tracking and shelved it.
2 hrs later or so the wind was really down, so i tried it again, wanting to check the tracking. when i spool it up now it starts to lean forward, as i lift off, it slowly turns aroundleft and starts to lean, totally not in control...! ?
i restarted it, thinking the gyro wasnt initialized, and it did the same dang thing!lifts, leans over, and turns right around. the gyro light is on, if i grab the heli and twist side to side, the gyro is moving the tail.im using the Art-Tech v2 H-H gyro. i even re-binded the RX (using an ar6200 with DX6I). its almost like my mixing is all screwed up. but on the bench it seems ok.
im at a loss here. any help is appreciated!
