Hello, Mark:
If it´s the FSR, I run one during a season, lots of power, I tame retiming the sleeve and fiting a .275 venturi, but it did very well with a Claus Maikis Indigo (beautiful plane, by the way),
Hope it helps.
Regards.
Manuel.

Mark,

While there are probably better engines out there for stunt, everything you need can be had from our moderator, Randy Smith.
