i understand the receiver problem - you could swap the walkera's 4-in-1 for a cp's 3-in-1 (might not work exactly right because of the cp's ccpm though) but that would let you use the other receiver - or you could just use the stock tx while learning then move up to a hbk2 arf

no issue with the ccpm, because the ccpm is in the transmitter =) If you use a non-ccpm transmitter then you can use the 3 in 1 and/or the receiver from the blade and it will pretty much drop right in =)
