38.. I've had no radio problems on my UCD 46 using Airtronics tranny
and Hitec gear on 6v.. I have my ant. on the very bottom of the fuse
exiting near the tail wheel, I drilled holes in the bottom of the bulkhead
and installed a plastic tube for my ant. wire. My servo wires are at the
top half of the fuse running in the same bulkhead but top cutouts..
Again not problems to date...
