Dalton,
The aircraft shown is mine and was built as Pats prototype. The engines are 2 Fox 15BB coffin cased. This was an exciting model to fly and it is probably one of the most consistent performers that I had. It was admittedly a little faster than a single engined model but it was one of the easiest models to fly. It really didn't need much to trim it either.
Now the bad part is about 60 flights later I was doing the inverted laps and the outside engine quit. The inverted landing was rough on it, Asphalt circles are like that on models. It needs work. I'll get to it sometime.
if you have 2 unused LA 15 engines laying around collecting dust then this is the one twin you should visit.
