I'm setting up my Rave 450 with Mini Vbar and getting low numbers on collective and cyclic using the 12mm holes on my servo arms (12.5 is suggested in the manual). I think 70 gain gives me 13.2 degrees pitch and the wizard is telling me to use 60 gain for cyclic. Vbar is optimized to run 80-100 gain but I don't know the effect of lower gains. Is this going to fly well or do I need to go closer in on the arms to increase the Vbar numbers? It's not a simple solution as this will give me less ideal geometry from servos to the swash.

For FBL the arms should/can be 10mm long. That is as far in as they can be without jamming into the center. I put some shorter brass balls on the swash plate (found them in an old robbe kit). That improved the cyclic ratio number, if it affects flying - I doubt it. But the numbers looked better.

Good luck
Petter

Thanks, I went over and reviewed MrMel's videos and Lo, he had the Rave 450 and similar (low) numbers but said he thinks it's gonna fly fine so I'm good with that.
