Hi Tomas, Thanks for your valued input, elimination has saved some time. As i stated the increased head speed WAS directly applied to 'Bank zero' which gave the drifting experience, so it wasn't any radio settings or Spirit settings in any other Bank.
I was driven away from a vibration issue as the
transmitter vibes were less than 13, Perhaps you can tell us what this telemetry value vibes actually means? and how it it can be of use to us?
I connected to the vibration analyzer, the vibes were excess of 120, this is the sab fbl mounting that bolts between the rear side frames, I changed to the fbl mounting that bolts to the gearbox, (with the 4 little rubber mounts) and the vibes were in excess of 300. Having checked Tail bearings, blades previously plus I'm pretty heavy on maintenance and oiling up, I changed the gearbox out, the vibes are NOW 39-37 in the higher head speed range now! PROBLEM SOLVED. The straight cut gears in this box will be Binned, although i will add, to turn the gearbox by hand they are as smooth as silk. I have the new helical cut gears, will change them out.
Thanks SAB for stitching us up with that bad design
