I am tinkering with the idea of mounting one of these in a Williams GP-38 which has spare room inside shell for the unit, still not sure if flush mount it or just surface mount for the first try, I have a cracked shell to experiment with for ways to mount it, on nose, in cab, on front of frame, etc.
I just ordered a set from Hong Kong with external mic I can trim or muffle so not getting the engine noise, and will see how the shipping goes.
Thanks for the idea Shawn.
