Re: Boats are cool
Yeah you can do 2-stroke glow, 4-stroke glow (alcohol with/without nitro methane, or diesel), or gas. The 91 is a Surpas. It has its own little fuel pump on the crankshaft instead of the traditional method of having a tapped crankcase and useing piston blow-by to pressurize the fuel tank.
Wankles are absolutely terrible RC engines. The age-old joke about the OS .30 sized wankle is that its the equivilant weight of a .60 2-stroke, the power of a .25 2-stroke, and the fuel consumption of a .45 2-stroke. The 4-stroke in the cap is a saito 1.80. piped out a huge pitts muffler on the bottom of the plane. Sounds great WOT knife edge with the exhaust pointed right at you :P
Na R/C engines are touch as nails. I had a funfly years back that nosed in over 100mph when the wings exploded from the air pressure pulling out of a dive. It was burried in the dirt. Didn't do ---- to it. The carb drum was notchy but it took like 10-15 min to get it to wear back down to the shape it should be in LoL
The worst I ever heard of is siezing the bearings or bending the rod from running too little oil. That only really happens to guys mixing their own fuel.
