I have a picture of how I cut the cowl to fit the DA-50 with the pitts mufler, I will post later. The standoffs are 3" and the ruder servo has to go pull pull.
Both batteries will have to go up front and the receiver in the rear and she will balance right on the mark. I'm on my 3rd gallon of ashless 32:1 and next week will go to Amsoil
I had some problems with the ruder servo not having enough power at first but I fixed it with a Hitec 5955.
Plane flies great
