G'day John. I am really glad to see someone "adding lightness" to their models. The Kadet with the 35 should really be a nice flier. My ARF Kadet presently has an Enya 53 which suits it really well. I gather the Kadet was originally designed with 29 size two strokes in mind. No wonder the wings get ripped off when someone puts a 90 four stroke in one. (Actually I did it as an experiment but the engine was only in there for two flights. It was insane and was sure to pull the plane apart sooner or later.)

Cheers
