[EDIT] Thread changed, scroll down to bottom of post for details[EDIT]
I attempted looping my BCP again today and had no luck at all.
First try I decided that I would leave it in normal mode, no good. Once it got inverted it dropped out of the sky. This seems to work good on the sim (granted that's with a nitro or large EP copter), but apparently the BCP can't do them in normal mode, or I didn't have it going fast enough. No damages that try.
Second try, put it into idle up and got it going fast, it did a half loop then the tail spun around and it got out of controll. It was, however, high enough up that I did manage to roll it back over and somewhat recover. It did have a pretty rough landing though (bent main shaft, no big deal, can be straightened).
I'm not sure what the problem is here, it seems to me that once it gets inverted it has a mind of it's own. I can do rools, loops, inverted flight, etc. really good on simulators so I don't know what the problem is.
One thing I did notice is that when in idle up the headpseed really drops when you go from positive to negative pitch (i'm not talking about jamming it down from +10 to -10 degrees, just slowly and steadily lowering the pitch into negative degrees does it). I'm thinking the rapid headspeed changes are what's causing the tail to whip around, my guess is the tail motor can't spool up or slow down fast enough to counter the rapid change in torque and thus the tail whips around.
Can anybody here actually pull off decent loops with their BCP? I have seen videos of the pro's doing all sorts of inverted flight, loops, rolls, etc. with it but it isn't specified what kind of mods (if any) the heli's have had done to them.
[EDIT]--------
I now know that mild 3d manuevers are for sure possible with my setup and will now be using this thread to post my looping progress and/or looping questions in, rather than making more threads on the topic.
