No Vid.
Just took it out for a flight. All was going well until 3 minutes in or so. Then the collective started getting very sensitive in both positive and negative. Borderline uncontrollable at times. I managed to get it into a stable hover and thought whatever was going on had resolved (was thinking maybe low voltage in the pack or some kind of cold temp effect on the Ikon). Gave it the slightest positive pitch to climb a bit away from me (it was a little too close for comfort given what had just happened) when it started to jump around again. Got it within 3 feet of the ground and relatively level and then hit TH and autoed in. Luckily got it down in one piece. On the ground collective control appeared to be responding fine. WEnt to take the canopy off and disconnect the pack when I noticed the front servo was loose from the frame. Odd. Turns out both screws holding the mounting plate to the top frame plate were missing! So I was more or less without control on the front left swash point. Not sure why this presented as collective control problems as opposed to cyclic. I suppose the anti-rotation bracket and two positive points of control on the swash and FBL roll rate control were enough to make cyclic manageable.
Can only assume this was a result of the cold weather. IT was the first cold weather flight with it. May have used too little thread locker on them and with the contraction of the metals being different it made the screws break loose.
Or I forgot TL on them when I was building it and it just took the cold to make them have enough room to back out?
Will have to go through and check everything and re-TL again.
Got lucky.
