Built from plan around two motors that were given to me. Yet to sail it (7/4/13) no water in lake!! Took 4 months to build from free plan downloaded of the internet. Build blog on this site. Weight with batteries 9kg, motors between them produce about 1000w over 1HP. On board lighting system from separate 4.8v battery. Maidened on 17/4/12 very successful! Gets on plane very quickly, much to powerful motors. (Motor: Emax BL2820-07) (ESC: HK 60A watercooled) (5/10)
