quote:OK,V4 2 stroke-sounds like a converted outboard engine,possibly direct injected. You need something like that in this application for it's power to weight ratio,or you'd have no useful endurance at all. But if he wants to go another step,the plated Wankels that are slated for the Moller Air Car would be a better option. Actually,I seem to recall that a similar vehicle using them has been looked at already.
Clever little dicks some of these Kiwi's, check out the late great John Britten's V twin Race bikes-possibly the only Motorcycle I'd ever have unprotected sex with.  :o

I may not agree with what you have to say, but I'll defend to the death your right to say it.

For the past 7 or 8 years I've been on my ride-on up to 6 days a week during summer months ::) Just purchased a brand new 15.5hp engine a couple of weeks back and not for what I'd call chicken feed :(  Enough time and money wasted on the bloody things already in my eyes. Like Bobcats and forklifts, good fun for a day or so but then the novelty wears off. Old dirt bikes, 40years+ and counting and I still can't get enough! No contest ;)

Here's a couple of shots from the lawnmower races yesterday.
The green mower in the photos is the one with some 4 cyl 4 stroke motor in it.
