end has more problems than benefits. Why should you do that in the car ?

Status: online 		There was a 10 page thread about a guy who built a 3 engine T-maxx. Thats three XTM 24.7's making a total of 7+ claimed hp! His name was madscientist (or something like that). But I say for the hell of it, why hasnt someone built a 1/6-1/8 scale model v8 or v6 engine yet?!? Ive seen many scale vehicles, but most are battery powered When I'm older and when I buy myself milling equipment, I really want to build a 1/6 scale vehicle with a either a flathead or v6-v8 engine. I have seen 1/4 models of them but they are really large and it pumps the price of everything up (around $4,000+ per engine, $13,000 for a car equipped with a 1/4 scale v8) My dream rc would be a have a 6 to 8 cylinder 4 stroke thats fully functional. At least a 4 gear gearbox, even though its scale, I'd want it to move, at least 70+mph. Of course with lights, remote start and kill, 4 wheel mechanical braking. The car would be like a real car which means the chassis would be sealed, no worries about rain or snow getting anywhere, internal fans and watercooled engine. Now thats a project I definitely want to do Tom.

Thanks, I had it as a shelf queen with 2 K4.6 engines for a couple of years. I decided to take it down, mod the chassis to mount the Axials, and actually make it drivable.

Oh yeah! Wheelies are possible not just from standstill, but even on second gear or low speed third gear!

As for the filters, the really do not affect air flow through the fins, the filters only obstruct the top fin. Additionally, at speed, I count on the eddy currents (turbulence) caused by the filters to cause a swirl flow of cooling air above the top fins to help with cooling. This was not the original intent, but after thinking about air flow one night, I realized that this actually helps cooling at speed.
