Hi,

A couple of things:

First: If your A-4 kit is the latest one, DO NOT modify the inlet! Advice to that effect applies only to the older design or the JHH one. If you've got the newest kit, with the redesigned inlet, you'll screw it up by cutting a hole in it.

Second: Avoid putting servos in the tail at all cost! If you use the recommended hardware (metal wire pushrods in plastic sheaths), you'll have minimal slop/binding. The servos in the tail 'work' fine, BUT it translates out to a lot of unnecessary lead in the nose. Two ounces in back might mean as much as 6 or 8 up front to counter it. This is a bird that you want to have as light as possible. Trust me on this! If you've got the newest kit, there should be plenty of room for the servos in the forward hatch area. Rig up the linkage first, then place the servo to meet it instead of the other way around. That way, you'll get the proper spacing between the servo and the inner wall of the fuse.

I've built this model six times, four for DF (Dynamax, Ramtec, Viofan) and two for turbine (P-80, JF-50 (for a customer)). I've built the scale and sport wing versions (recommend the sport wing...) stock, and with modifications (split flaps, dive brakes, scale refuel probe) and it's a really super airplane as long as it's not too heavy.

I hope this helps....
