I'm kitbashing a great planes p 51d kit into A 36 Apache EW998 and I'm having some problems with the dive brakes, both in terms of size and in terms of their actuation. Anybody done this before or have any tips for them. Also does anybody know the size of the airbrakes on the original? Also is there a good muffler that would allow me to mount the engine inverted without too much of the muffler showing? The engine is a thunder tiger 42. Is there a good and inexpensive bomb release system out there that will fit in a wing pylon? All help is appreciated.
