Title: It continues with the TRex 450 und CC3D
Post by: jochene on August 14, 2015, 09:25:52 am

Hello there,
Last night I had a little time to test my 450'er again in rate mode (swashplate and tail rotor).
Then I have tried "axishold" on the swash plate and tail rotor. Also works pretty well.
However, my problem remains that I have a see-saw on the swash plate to short control movements after taxes.
However, I still fly with low head speed, have the correct reduction is not found.

Hi
Trying to get cc3d and Librepilot to work on a 450 (FB) and so far not success.
Is it possible to get your config file to 'import' and maybe I can compare with min config.

@jochene
Is your flybar weighted or designed for beginners?  That will limit the response speed, and with a slow response speed, there is no easy way to get it to respond faster (we recently removed feed-forward).  The solution would seem to be to reduce your PID's to stop the oscillation.

If you have flybar weights, you could start by moving them all the way in, or removing them?
