U replaced the 4-in-1 with a what?? and it works with your Dx6i? HHmm I have no idea what the 6200 is all I do know is the 4-in-1's are for co-axels no?? They do the swash mixing, and you can replace them with?? So if its possible I could even replace the 4-in-1 on the LamaV3 and use my Dx6i with that as well???
