As i started building i tried to do it the cheap way.
How wrong i was, the used 820 motors couldn't handle the amps and after the third burnt motor i decided to put in the Ultras.
Wow! This was better, but the amps were even higher so i fried 60 very expensive cells; back to the drawingboard.
I also had to loose some weight so i came up with the new sanyo 4/5 cp cell which can handle currents up to 60 amps with ease.

This made the final difference and i went over 80 Kph with the propshop props; later i tried a pair of graupner 51 carbon props and this really made it fly, and also the sound of the props beating on the water is awesome, its almost like two Lamborghini engines are driving this beast !!

The next thing is the paint job, as i am a big fan of the victory team the colors of victory 7 are going to be used, check back for further updates..
Below you can find some pictures of the building progress and some action pictures.
