Hi!

Any idea about the gear ratio Curtis is using right now on
his OS 91 C spec. ??

Thanks

8:0 in his 3D machine. He uses 7.6 or something in his FAI machines.

Thanks Simon!

And how's your Webra doing? Will you stay with it or go for a japanese big block?

Best regards

On the website of Curtis it shows he uses 8.4:1, or was that with the old OS91? I'm still in doubt to go for 8.45 or 8.18 with my YS91 for my new ship.

Arjan,

I believe 8.4:1 was what Curtis was using with the old OS 91. Unfortunately the engine-part of the site was not updated since then.

The gear ratio mainly depends on your flying style. For F3C you should not go higher than 8:1.

Best regards

I'm currently selling the Webra Vigor to make way for another CS with a C Spec 91.

No problem with the Webra, it's going very well actually, but now I'm pretty heavy into contest flying I want two identical machines

Glad to hear you like the CS. I'm working on one right now. I think I will stay with the YS 80 for the moment. Was running one in my FREYA-EX last year with very good results...

Looking forward to hearing your report on the C-spec.
Best regards
