Well my mx400pro is still down. I need an ar6000 Spektrum receiver and ESC to get it running again. I could put the original motor and ESC back on it but I really dont want to downgrade it's performance. I decided to purchase a trex 450se v2 kit (with motor and ESC) so I moved the receiver over to it. The trex 450se is a lot more unstable in the wind than the mx400pro but it's cyclic performance is way better than the mx400pro. I can definitely see why most 3D people use the trex and not an mx400 heli.
Unfortunately I wont be able to get any more graphs on the mx400pro until I get spare cash to get the spare parts for it and that is going to be a low priority because I want to save for a Jazz ESC again. Previous one died from a crash in the pond.
I have the micropower elogger in the 450se right now and I am trying to decide where to install the RPM sensor on the trex but I plan to go with the magnet sensor whenever I get a chance to go to my local hobby store. I plan to put it in the spare set screw hole of shaft collar on the 450se. It has a hole on both sides of the collar unlike the mx400pro. I think I am getting off the subject quite a bit though here :).
I assume you are using the default ESC. It seems like when you were upside down(2.5 - 3 minutes into your flight) your RPMs increased. I would try to tweak my throttle curve to reduce some throttle at low stick in idle-up to bring it down some or increase pitch at low stick in idle-up if the pitch is too low for your taste. It is nice to be able to analyze performance like that with the micropower elogger.
