Dazz, My son also has one, but he purchased it ready fitted with RC etc. We had lots of problems with drive linkages, loose shafts and so on. On its maiden launch it took on about a litre of water. We got it exchanged, but had the same problems. After many hours of re-building it is now seaworthy and going beautifully. One thing I forgot to mention, we had to wait five months for it. Pete M
