My TT Neptune came with a basic four channel radio installed...the tx is functional, but very plasticky and almost toy-like. I want to use my HiTec Optic6 tx with the Neptune, but the question is...which crystal do I use? I presume I'd need the TT tx crystal, but would they be compatible? I don't really want to strip the Neptune down again to replace the rx with the HiTec one unless I absolutely have to...
