Ive sold the both the hull in this thread and the catamaran hull and decided to build another which ive now finished. Took it out twice but then on the 3rd occasion for some unknown reason my boat just burst into life. I couldnt work it out at first, then it dawned on me that the speed controller ive been using has was stuck in recovery mode and faulty. I thought was something was a bit off because the lipos would come in dangerously low, but it hadnt crossed my mind it was because low voltage cut off was stuck on. Ive replaced the esc and sure enough the boat runs as it was intended
Now the other hulls are gone ill never know what they could have been cable of.
