am using the existing rap 30 gearing which I believe is 90T main and 9T pinion
on 550 blades. But am going to a 50 size motor, will this gearing work for the 50 size motor and 550 blades or should I just convert to 85T main 10T pinion for the 50 motor? if so can I still use the 550 blades or go to 600s already got the new gear parts just needa conformation

30 main gear is 86T. If you're putting the OS50 in it, go with the 50 gears and blades.

The gears I sent you will work even better, it's the Titan gear ratio of 8.7

Will 11T that pinion work with the R30 V1 clutch bell?

The stock R30 main gear is 86T and is the only one that will work for the 9T pinion. Count it again

The stock gearing for the Titan 50 was 1:8.5 standard. You could buy the 1:8.73 ratio as an option.

yep ur right I just posted it wrong, the titan and reg 50 had the same gearing, the optional gearing is to swing the 620s a little better with a .50

The tooth count is molded right into the top of the gear.
