Art,
That is not up trim, the APG when positioned as the directions indicate will give you the proper neutral aileron

, no way you can set the neutral by the "TLAR" method. I've built the 4*40 way back when it was introduced, and my favorite plane now is my 4*60 with a Saito .65 on it, this is the only plane I have built that actually has the engine installed that's shown on the plans

, just happened that way[8D], good luck with your 4*40, I'm sure you will enjoy it!
