Hey thanks for the tip..I'm home for some R&R and right now I'm working on an esm stuka sometime next week I'll get started on the zero. There is a piece of ply wood with threads for 2 screws does that wood go horizontal or vertical I seen the manual and there are 2 pics showing them in both positions which one is correct and also I want to use pull pull system and suggestions? I also have a small servo for the tail wheel so I can do both is I want. What did you do? Tahnks for welcoming me back I appreciate it.
