can anyone give me the ground clearance dimension about 4" behind the baggage compartment wall for a -6. you guessed it, that's where the lower VHF antenna's going!
Pat,
That's going to depend on a couple of things.
Mine has 17.5", but that is with an Aircraft Specialties tailwheel and the airplane unloaded. The dimension will be less with Van's tailwheel.
The Aircraft Specialties tail wheel raised everything 2.5" at the rudder bottom directly over the tailwheel.
Since the location you're interested in is approximately 1/2 way back, my guess would be that it changes about 1 1/4".
