i know many of you are airplane guys, or at least the regulars here.
i have a nitro blizzard snowcat from kyosho, i fabricated a front blade attachment for pushing snow, only prob with this blizzard is its ability to push snow at low rpms, since i cant lower my gear ratios anymore than i have. from a dead stop is has allmost no pushing power untill it gets up into the powerband. i was thinking diesel might be the answer to my problem?
would diesel make more torq at a lower rpm ?
its a cheapo little kyosho .15 engine in it right now, i was considering 4 stroke or electric for power to my problem because eather one would give me great low end slow moving torq, but both options arnt cheap eather, electric would be cheaper but require heavy modifcation, and i love the sound and fun of IC engines.
do you guys think diesel is the answer to my problem? or should i look else were?

If you love the sound and fun of IC engines, then you should definitely get yourself a diesel anyway, just to play with... You too can smell like this ! Whether one would be ok for your snowcat is another matter. Sorry that's not really much help is it? Alan

Quite honestly I would use an electric setup in that application. If you want to stay with glow and top speed isn't an issue, I would make a custom gearbox. The little car engines don't have much torque to begin with, diesel would help but I don't think it would be the solution. Changing the gear ratio will yield much more torque than going to diesel.

You could fiddle with the clutch that's in it now. It might not be locking up tight at a reasonable RPM. You will need to make sure it doesn't lock up at too low an RPM or it will bog the engine. Check with the car guys for setting that up.

The second issue is the engine probably isn't at full throttle at the RPM you are running at(because you want to be going slow), meaning it can't make full torque.

electric would be an easy resultion, but i love the ease of nitro, and not having to change batteries and having spares charged up etc etc. problem with my current setup is, the forward reverse tranny setup is perfect for its application, its the same tranny on older kyoshos with the "quick reverse clutch" system.
the spur is where the 2 speed is, being its a old kyosho 2 speed i havent been able to find different bell/ spur combos, i might be able to rig some thing custom but i cant just buy things to try them, hard to find matching parts. i dont care about the 2 speed because i just want super slow torq for pushing snow. so if i could rig a regular bell and spur on it with a high ratio i would be set with what i have, i was hoping maby diesel could produce enough torq at the low rpms my motor engages, a higher engagement rpm would burn up clutchs even quicker, and still wont let me move as slow as i want with that torq. id love to put a 4 stroke in this but its a expensive project, i know a 4 stroke would completely solve my problem with the low rpms and torq produced. but i cant afford that issue right now.
thanks for your input guys

I do not have a kyosho engine, but assuming it is a schnuerle ported engine you might pull the cylinder and block the boost port (the one opposite the exhaust) with a piece of wood (not permanent). The boost port is mainly for high speeds. This should provide better breathing at low speeds. If there is a diesel head for it, give it a try.

If you are using gear reduction then you will need the high speed power of the engine, even to push snow.
