I'm just posting this for information to try and help others.
Since I "upgraded" my 250 to FBL, I have been chasing horrendous tail problems. I'm not too sure whether it was the FBL conversion itself, or that during this time, my flying has improved in leaps and bounds - but whatever, the 250 was close to being sold for parts after having a small fortune spent on it.
Here is the spec now after this hassle:
The main thing that most of you may want to know is what was the key thing that solved the tail wagging?
It was the MH tail assembly. Yes, it was expensive @ £50 or so, but this item is beautifully machined, and absolutely no slop whatsoever. I don't understand why Align could not achieve something similar - as the stock tail I had generated enough slop to rotate the blades about 15 degrees without moving anything else.
Just been out for first test flights - wound up the tail gain to about 45 on a DX8 and she now flies absolutely beautifully. No wagging, despite any moves I could throw at it.
I also have to say that the Scorpion motor upgrade, in conjunction with the governed set up is a revelation - amazing power on such a small heli.
Loving the 250 again now.....
