I always thought it was better on top:-) But my last two planes are
internal and they are stright(little guide tube that's a pain to get wire
through with stops on both ends) and as far away from rods as possible
(even tho there C.F. rods) With both I get over 100ft. on my range
check with plane sitting on table. While flying I stay within 25-200yds.
But at times I do fly high.. The way I figure, It should get the best
reception since its an unblocked path..
