Troy:

I've got a YS-110, but I wanted to ask: will a JETT 90L (which uses a 12x6 or 12x7 prop - nothing bigger) be appropriate for the Focus Sport? From the pictures, it seems that the model does not particularly require a very large prop. The JETT turns at 15,000 RPM and has great throttle response. In theory, that should be OK for the Focus Sport.

Please advise. Is this model totally unsuited to engines like the JETT? Is it made specifically for 4-strokes like the YS-110?

Thanks,

Atul Saini
