Thanks again for the video, Steve. I'm still amazed at what an i-phone can do.

Looks great! I will have to see about those engines, would be a nice repower for my 52" Bronco.

I used to live in Tacoma when I was at McChord AFB. Is that the field out past the Roy Y?

Airraptor: Yup! about twenty min. south of the Roy Y. Right by Hart's Lake.
Twin_Flyer: A pair of these engines in a 52" ANYTHING would be a missile! A guy in the club had a TwinStar with a pair of these and he was doing 100+ mph effortlessly.

I had a pair of OS .25FX's on my 52" bronco and it was in the high 90's, you should be able to get a bit more with the .32's. I loved that plane, still not sure why I sold it.. Wish I had put retracts in it.

Hey buddy, looking at your thread here helped inspire me to build my proud bird with an evo 46nx. Great lookin plane and I like what you have to say about its flight characteristics.

A .46 is pretty excessive from a standpoint of weight, but the power would be fun... I still have the plane and I still love the way it flies. Have to be careful because once I got the engine on the pipe, the wings flex a LOT in turns. Watch your ***** with that .46.

Oh yeah I plan on taking it nice and easy on the g forces. I agree with you on converting to glow as well. I just prefer glow over electric and its neat to change some things up. I dont have the time to build from scratch so taking an arf and making it my own satisfies me for now.
