Funny you should ask. I'm still trying to decide which hook-up will be best for this application. I believe it calls for twin 'Y' connects on and for the aileron RX plug in the book but I usually hook up seperate aileron servos, aileron for left and AUX 2 for right connect. I'll sleep on it for the night and start again in the morning. I should go by the book but I dunno, we'll see. Other than that, it's pretty much done. I'll install dummy motor after a test flight [if it does'nt cause cooling problems like it did on the Super Stearman] and go from there. This really is a top quality ARF and I can hardly wait to get the second one........ I'll also include weight and balance needs tomorrow too with the pics applicable for the OS 1.20 install.
