Hammer, Two servos? Why go thru all that BS when one standard servo will do the job. However. I did not add the pieces under the servo plate to reduce the depth the servo goes into the fuse.( see attached pic.) I glued the plate directly to the wing.Plenty of clearance now. I placed the battery on top of the tank. You will be tail heavy !
Give a hollar if you need any help !
