cruzmissile, I had set up the proportional controller beforehand, and can get the yaw somewhat under control, what I find is that once I get any air at all the heli decides to grab some serious speed sideways regardless of the trims and in compensating for that I get sucked into a side-to-side swinging out of which the only escape is a sideways unplanned maneouvre into the terrain (aka crash).
The balance seems good staticly, if I hang it by the main shaft it seems to be pretty much level, the only thing I haven't messed with is the yaw gain. I've read the thing can get a bit twitchy with the gain set to high, but it's not spinning out of control, I can keep the yaw under control no problem.
I'm just getting the impression from all these posts that the Blade should be fairly easy to get to a controlled hover, and I can't even get a foot of air before I'm swinging wildy side to side or fore-aft.
