The 30 has a higher gear ratio, but I forget the tooth count off the top of my head.

The problem with the Raptor is there's no room to adjust mesh so you pretty much have to run 8.5, 8.7 or the 30's 9.6

well, i know the 30's clutch pinion gear is 9 tooth and the 50 is 10tooth but the main drive gear i have seen one that was 85 teeth and one 86. i wondered if there is one with a higher tooth count. i have an old 30 v1 that i tried putting the 9 tooth pinion in and it somhow isnt happy. when i power it up, there is massive vibration in the clutch shaft system. the 10 tooth shows no problems or funny sounds. the pinions i have been trying are the v2 version as i converted the clutch bell and start shaft assy to the v2.

10/85 and 9/86 are the only workable combos unless you go to the Titan gear set.
You cannot run 9/95 or 10/86

I like the optional 11-96 gearing best myself. You have more torque to the blades to prevent bogging.

No it is not.
You have only the 3 combos available. You cannot adjust the motor/pinion, so you cannot change mesh

Can I run the OS 32 with the 50 gearing ratio just for forward flight? No fancy 3D ?
And just up the throttle curves?

That would be a super economical setup with very low power. As long as the motor does not overheat it would make a good endurance helicopter.

Also you will probably have to lower the max pitch to +/-8 so you don’t pull the engine down so much that the clutch starts slipping. I once helped a beginner that had the throttle curve so low that the clutch slipped during hovering. He was thinking that the Raptor clutch design was no good until I got him to lower the pitch and raise the throttle then he was a happy Raptor owner.

Ben, Thanks for the response!
Yes, I don't go over plus 8 either. I have a rubber liner from one
of those Raptor clones..forget the name? But never tried it.
