The Department of Aerospace Sciences and Technologies of Politecnico di Milano has recently launched the Chippy program, aimed to obtain a very low cost unmanned air vehicle platform capable of being used in support of didactic activity in support of the M. Sc. “Flight Testing” course, with the additional capability to serve as an affordable and dependable platform for research activities. Starting from the unique requirements in terms of weight, power consumption and cost originated by the particular characteristics of a 650g maximum takeoff mass, battery-operated, academy supported unmanned air vehicle, Chippy's telemetry system has been designed and implemented using IEEE 802.15.4 wireless protocol, which has shown to be capable to fulfil pretty well most of the requirements and constraints. Details are given on the integration of the system with the air platform, as well as on the concurrent development of the complementary ground station. Finally, results of the on-field testing and evaluation campaign are presented and commented
