does the tekin have a diode inside or is it outside? i dont think diodes are too important, because i would be able to put it under and use it as a rest for the wires coming off. That new sidewinder looks awesome for the price, but how many inches would you say. Is it as small as the hara and lrp, around 1''x1''? what brushless motors can be used with it? only the mamba's? im asking because i dont think they have a 17.5 available for it, do they?
