I have a spare Vision Plus 5.8ghz controller with the ch7 on the back (non tilt wheel). I have used the tilt wheel before and must commend dji on a great job. I've done a few tilt mods to my controller and still not satisfied after having a taste of what dji offered. So.. call me tight.. The upgrade 5.8ghz controller in aus $150. The upgrade 2.4ghz on ebay is $75. What I want to know is - can you take the 5.8ghz transmitter board (only) from the old transmitter and plant into the new tilt wheel transmitter? This will save me $75 and will put my spare controller to good use.
