Had a few minutes to hover the Trex today... Noticed a little tail bob going on. Never had that happen yet. On the 14th run with the battery so far since I have had it ready for flight a month or so ago. Anyone know on a tail belt heli what can cause the bobbing action ? To loose of a belt maybe ? Can't remember what few things can contribute to this. Any advice would be greatly appreciated... It was windy when I was hovering it outside, more than what I should be flying in, but after work I had the bug to burn a pack and couldn't resist. Hovered the CPP also, and the darn wind just about took it away ! Hit idle up and gained control however. Still a lot of fun but I think I'll wait next time for a calmer day.
