Hi there Chris.
I too have bought the Frsky system after your review, and I am pleased to add that the module simply slipped into my Futaba 9CAP without any sanding or modifying in the slightest. It would appear that Frsky did indeed listen to what you said and have remedied the module fit problems- which is better than a lot of the other manufacturers out there. Please keep the reviews coming as it helps us to make informed decisions in techno world of ours.....
