I have a old X-SPEC and i am thinking about to change the main
gear ratio to 8.25 like the turbulence, x-spec is 7.91 is tooo low,

what are the parts that i need, and can i use the same main autorotation hub and buttom gear that on x-spec, just change the pinion gear and main gear...

thanks

Tony

You will need a new main gear and possibly a new pinion. I've done mine a while back and made a nice difference.

Edited. See Terry post below. Mine goofed up the url's for the parts you need. No use fixing it for duplicate info when Terry has it right in his.

Thanks for the follow up Terry. The links looked right when I wrote the message, but they weren't hyperlinking in reality as I had wanted. We'll go with what you have above.

RE the meshing, as per the norm with Freya's with the plastic upper frames, the gear mesh is fixed and will be fine with the 11 T pinion or pinion/bell and the EX91 T maingear.
