Just wondering how many of you have built nitro powerer crawlers and what is your method of cooling the engine? Electric fans, etc.? Any pics you might have would be welcome as well.

I haven't completed my truck yet, but I can tell you that a 4-stroke motor will run somewhat cooler than a 2-stroke. Plus, the 4-stroke can be a bit more controllable at lower engine speeds.

I will be using liquid to cool the engine, with the radiator cooled by a fan.

Will you be using a miniature waterpump or use the siphon-and-pray method of circulation?

It will be pumped, with a reservoir, radiator and relief valve.

Heretique, Any teaser Images yet...

I have posted some images elsewhere, but nothing recent. So far they are just featuring the chassis and body. The suspension has changed from a Clodzilla-style cantilever to a crawler-type setup in the interest of increasing travel and improving the flexibility of operating the truck at slow speeds. This is the reason I decided to liquid-cool the thing.

As far as the cooling system goes, I'll post some images as soon as some significant progress is achieved.

Thanks Heretique... !!! Can't wait to see them... Take your time, no rush... none at all... ladedadeda... Now ???... Ok I will wait...

I did see your other images in the other thread... amazing work...

If I only had a garage or a room for a milling machine and lathe... !!! [&o]

I'll Have to stick to tube frame welding till then... But SOME DAY !!! [8D]
