Ultra Stick .60 engine discussion
 

I'm flying a Ultra stick .60 with a K&B .61 flies good, but wanted more, so I've purchased a OS FX .91 For all the power a man could want- Anyone out there using this engine on the plane? What props are being used and how is performance?

Thanks!

I'm using a Super Tigre G90 throwing a 14 x 6 APC prop which gives me plenty of power to spare.
