The Jeti's goal was to make the best with the several years experience in development of this kind of controller. All controllers contain new type of voltage regulator for receiver and servos – so called BEC. By using this component the new possibilities occurred - to use BEC for models with more battery cells. Also the fact that number of servos is independent from supply voltage is very important.
SPIN controllers together with JETI Box provide the best system which allows an optimal setting for any kind of drive.
Please note that opto speed controllers do not provide power to your receiver and servos, therefore a separate, stablised power-supply should be provided using a voltage regulator such as the Jeti Max BEC or Max BEC 2.
