well I would suggest you need only find the place to tap into the board. HL it would seem has little if any creativity, without something to copy they seem to be stuck with what do we do next.
I don't see this affecting the mamba, the sound module would have been the big thing but appearences have the slots in the same spots so I would think it is the same function same program etc.
the RC part well to be honest if it has nothing to do with the Mako stuff anyway so the 2.4 part is a moot point. there is enough older HL stuff out there that needs to be bumped to 2.4 anyway.
I think everyone wins on this one. Eventually.
