Default Question on new YS

Dave,

I have a YS140 Sport on order ... I know the threads are 8 x 1.00, but does it step up after the threads, like a Saito, or will a 8 mm prop reamer/drill be sufficient?

Really looking forward to my first YS!

The crank is constant diameter, no step.

Enjoy your new toy, we appreciate your business.

Thanks very much Dave! This support forum is outstanding - hope i don't have to use it

The engine arrived today (wasn't expecting it until the end of the week) so I guess I jumped the gun on the question...

Followup on the new 140 Sport...

First, thanks Dave for the YS stickers!!

First ran the 140 2 weekends ago, one tank, adjusted per instructions from the web site, , had no problems...

Last weekend, took it back to field, ran another 1/2 tank, made final adjustments, went for the first flight - awesome!! I am now a YS believer! Running 30% Cool Power Heli, APC 18x6 prop,
kept it a little rich - to keep rpms about 8600! I still can't get over the power this engine has...
Also, engine ran solid throughout the entire flight... more flights hopefully this weekend.
