I just bought a Uproar 60 and am seaking advice on engine choice. I want good vert. but not too expensive. Thanks!

OS 61fx makes it very fun. A 91fx would be even better. Be sure and use 4-40 pushrods for the control surfaces or other heavy duty methods. Flutter from my cheesy 2-56 pushrods caused mine to crash @ full speed. Use throttle management. This airplane is a smooth flier that enjoys inverted 2 feet off the runway. As far as not too expensive....maybe try ebay.

Thanks for the reply. I wasn't sure if the 61 fx would have the performance that I wanted.

Try www.justengines.co.uk
they have info on the Irvine range of engine, which are just brilliant, and very cheap. They run smooth, eay to set up, and very powerfull. I think that they make a 72 which should do nicely.
Good luck!
Robert.

Robert, thanks for the advice. I have been to the just engines site and looked at the irvines. They look very nice and I have seen nothing but great comments on them. I think I may have a winner!

I have the 53, for about 2 years now. I never had to do any maintenance on it, and it runs soooooo sweet. Excellent engines, you should really try one!

For 99 bucks you can get an MDS .68 that would be perfect for this application. Just remember no more than 10% nitro, use an OS 8 plug or a cheap idle plug and put a speed prop on her, she loves to rev!
