Peter - Forgive what maybe a "newbie question from an newly back to the hobby old guy here in the USA. I'm planing to build the Harmong as my next plane. I looked at the article, I have the Hobby Store plans, and am not sure if you used a "std" or a "micro" servo for the ailerons. I plan to use an OS .25 AX engine in mine. Thanks and Thanks for so many great model designs! Leo
