There are small 4 stroke engines that use pre mix oil in the gas for lube. Go to Stihl's web site and look at their 4 stroke weed trimmer. I think a 4 stroke large scale rc would be cool. I love 4 stroke dirt bikes and quads. I would never buy a 2 stroke bike or quad ever again after my first 4 stroke. The rock crawler would be the shiznit.
are you serious....4 strokes will never give you the same excitment as a 2 stroke will. I race both(yz250 and yz250f) both race bikes....the yz250 is just more fun...ill blow away and stock 4stroke(maybe not a 4stroke race bike) but the 2 stroke it more fun.
its like with shifter karts...they use small 2 stroke engines and haul arse! Some one needs to make a large scale car using a yz85 engine with a shifter car setup, now that would be an rc car.
