Hey yall,
Looking at putting a YS120 SRX into a Glogo.
Is a different pinion required than the one that comes with the kit.

YS Recommends:
You should be using an engine to main rotor gear ratio
of 1-7.5 to 1-8.2. Please check with your helicopter manufacturer to obtain the correct gear ratio.

Hi Ryan,

please excuse the late reply.

The GLOGO comes with a gear ratio of 8.15:1 (13 T pinion, 106 T main gear), which is well within the range recommended by YS.

See Product Data here.

So ... I don't quite understand the question grinning smiley

Kind regards
