In case you've missed this, HobbyKing is now selling a RC transmitter designed for APM/Pixhawk, with all the flight modes mapped to knob settings with mode LED indicators. Just $58!
The Quanum i8 8ch 2.4GHZ transmitter has primarily been designed for the popular multi-rotor market, and has been mapped and matched to APM and PX4 flight controllers, bringing ease of use and programming to a normally complex product. It can however also be used with helicopters, fixed wing aircraft and gliders.
The Quanum i8 transmitter has 8 channels, the first 4 channels being the 2 dual axis sticks. The 5th channel is a 6 position rotary knob which is perfect for different flight modes on a multi-copter, the position of this switch knob is shown by the 6 LED's on the front of the transmitter. Channel 6 is a 3 position switch and channels 7 and 8 are slide switches. The stock radio programing is matched to APM and PX4 flight systems in channel mapping, direction, Aux channels and the 6 flight modes via the detent rotary knob for a plug and play solution. The i8 is a fantastic radio for other Multirotor FC systems with map able Aux channels, channel reverse and other custom features. Included with the system is a set of labels for labelling the various flight mode LED's.
