I may have used the wrong sheeting on the tail pieces.

] Oh well. I have an excuse to visit the LHS now!! I can look at some engines while I'm there. I just might take the Saito 100 out of the 4* and put it in the Chippy then get a Magnum 91 four stroke for the 4*. I'm going to use two aileron servos instead of the bellcrank setup. I'll just copy the servo tray design off the 4*. I am looking forward to this season since I got the basics down last summer (barely). Thanks for the replies.
