I'm considering building the baby blender. I have a hobby king radio (6 channels) (HobbyKing 2.4Ghz 6Ch Tx & Rx V2 (Mode 2) to be precise) which I plan to use. However, I know that the baby blender is 4 channels, could I add a servo to the bottom to make a bomb bay? And if so, which channel to plug it into and would it even work at all? Thanks!
