Radio Controller
ALTA Pro supports a variety of radio controllers as outlined in the Flight Controller Specifications. A minimum of five (5) channels are required, with four (4) used for flight control, and the remaining one (1) used for mode selection.
A radio controller with between six to ten channels is highly recommended to make use of Return-to-Land (RTH) and ALTA Pro’s other functions. It is recommended to use a radio controller with a three-way switch for Mode selection and a two-way switch for the Return-to-Land function.
Flight Battery
ALTA Pro can accommodate a variety of Lithium Polymer (LiPo) flight battery packs. Battery packs must be 6S, having a nominal voltage of 22.2 V. Only run ALTA Pro using two packs at a time. Each pack must have a continuous discharge rating of 250 amps or greater, and a peak discharge rating of 500 amps or greater. For additional information on expected flight durations, refer to the Performance Section of this manual.
The use of flight packs which do not meet the voltage and discharge rating above (22.2V nominal, 250a continuous discharge, and 500a peak discharge) can cause damage to the ALTA and the batteries.
