MOONDOGGIE....you will be fine with a Y-harness...that is what I use....I have never set up the .40 size for flaperons...she lands like a dream as it is..harriers are a breeze......I do not know how much flight experience you have...she was my 2nd plane, and I could not have wished for anything better. The plane is still light in weight, yet sturdy as heck. She sets in for landings just amazing...just line her up..cut the throttle and she will float in almost by herself.....Depending on your engine...she takes off like you have never experienced....
I have tried a few other planes since..all I can say...the T _ _ _ T will be in my hangar, as long as this plane is in production.There is no plane, that I have flown so far, that can come even close to the fun I experience with the T _ _ _ T!!...period!!!Do I need to say more??....other than that...welcome to the group of T _ _ _ T addicts....you can not wish for a better place to gain experience than the guys here at this forum..I consider them part of my family..
