RE: Never to late...
Hi Nick,
I am glad I was able to help you.
I do not have schematics, but if I can help with anything else, please let me know.
I will probably be converting mine to 2.4 using a 2.4 RF module, probably using one from a Hitec Aurora A9, that is, if I do not sell the ProLine - the sticks are really nice in the ProLine radio.
