Default Supertiger 90k on a cermark f-20?

hello right now im negotiating my 61fx to take out an enya 61 heli and put a super tiger 90k on my cermark f-20. so here is the question would this engine be good to take the speed up?my guess is that im making about 100MPH with the enya 61 and want more! .if i put a small prop like a 12/6 would i get more speed? or i should stay with the 61?
thanks

That Super Tigre isn't really ported for speed...with at 12/6 doing like 13K rpm you won't get speed...ThrustHP predicts like 73 mph pitch speed on that prop.

Default engine

I put the 90"K" in my Direct Connection f-18 and it flew great @ over 100mph. The 90k is ported for RPM where as the 90G is not.
I did use the APC 12X6, a little more top end with that one. It's like flying a dart. The next set of DC f-18's I build will be carbon fiber reinforced and I'm going with the Jett 90 lite. IF you want more speed without spending the money for a Jett. You might want to try the MVVS 71.
Good luck
