I had the nitro V and was not happy with it. The Return to shore system was great, but it required the boat to have a clutch. That stupid little clutch slipped way to much. It takes alot to get a heavy boat on to plane and the clutch couldn't handle it. I also didn't like the exaust set up, it has a 10" piece of silicone tubing that burns apart after a tank or two and you have to keep replacing it. The drive line was OK but it was made out of cheap parts. The set screws stripped the first time you tried to remove them. And last but not least the prop is plastic and easy to break, but hard to find. The shaft size requires you to use their prop only.

Just my 2 cents on the Nitro V.
