Yep and running on Wildcat 10%nitro/18% oil.

I've found that the 1.60 does not like running lean in the beginning... at least I can never get away with it... always seem to get flameouts from going lean on verticals.

Once I have a couple gallons through it, I'll be able to lean it out a good bit. Even with it fairly rich it has lots of power. When it's broke in and leaned out it'll be even sweeter... then some may add some hotter nitro and really have the power...

I would have to agree with the CAPtain... It flies very well at this weight and could handle a 40-50cc engine fine... but you will exacerbate the snapping. Like he also said, the BME55 if it comes in all it's supposed to, will open the gasoline pumps for MANY of these 1100-1200 sq in aircraft. Also the new ZDZ40RE-FAI might prove a good match as well...

I'm not sure why this sudden trend in trying to put 50cc engines in these large glow planes. The question would be why? When there are SO many great choices for 50cc applications with 1350-1450+ sq in. of wing area. They still are fairly easy to transport and fly inifinitely better than a weighed down 1150sq in aircraft. Each aircraft is intended for a certain flying weight, going above that often destroys the flying characteristics of that plane.

Some get into gas that way... I dunno maybe it makes them feel more comfortable staying in a large glow plane but adding gas to it than jumping to the next larger airframe... but in the long run they miss the real benefit that the 50cc class really affords...
