thesnapper,
We put it on, powered up and flew. It worked well. We did make some small adjustments to the gain later, but not big, and we probably ended up pretty close to how it came after we got done fiddling. But if it has turny thingies, I can't help turning them. :-)

The conventional wisdom is that with 2 ESCs, the BEC from one should be disabled to prevent possible glitches. Cutting the red wire from the smaller ESC is a good way to do this. (presumably, the bigger ESC has a BEC that can handle current batter) There is some debate as to wether this is necessary. But it certainly has no down side. I cut mine.

What cells and how many are you using? Come people have reported tail wag that won't go away when using the CSM hlg200 with high cell counts. 3 cell LiPos do this. But only in some cases, and only with some ESCs. Many were able to correct this by cutting the tail blades slightly. Others changed the tail ESC. I did not run into this problem so I really don't know how bad it is. Brother #2 runs the CSM on 2 celll LiPo and does not have the problem.

And just a FYI, I am still flying my FP machine. I have done a lot of playing, brushless, seperates, moth conversion and so on, but I never have progresses beyond side in flying. I need to kick myself in the butt, learn nose in, learn circuits and then buy a pro. I'll get there. But at this rate, I'll be 90.
