My spe40 has been in the air 3 times now. runs extremely well. instant starts and perfect idle. Probably have about 1 hour on it so I expect it to get even better as time builds. If my wife had not threatened me with several unpleasant penalties I would buy an spe26 so I would have an excuse to build another big plane. I don't supose my ww2 fighters taking up the family room and a 105" Jenny in the living room and my other stuff in the spare bedroom has anything to do with her attitude.
