Those are cool. A buddy of mine got a clear plastic one from Auto-sone for like $50. He put it together, ant it has a hand crank that pooerates the crank, pistons, cam, and even the valves open and close!! it also has a fan and alternator. Very useful for explaining engines to people that have no idea.
I havent seen those, but I have seen the clear plastic ones.
I have one and I only paid 12 bucks for it at a hobby store.
Sorry to hear your friend paid 50 for it
I jsut sent the guy an email. tryin to get power numbers and a price. I also have one of the clear plastic ones, need to make another one, i put the thing together in about 2 hours, rather shoddy job...was TOO sleepy...(it was about 3 or 4 in the morning)
We have some irrigation pumps that take about 70 HP to turn. I wonder if one of those little things wouold save us from having to run two generators to feed an Electric motor, which is very old.
These Conley engines in the link above have been around alot longer and run on nitromethane. They are glow plug type 2 strokes. I have personally seen a 5 ft dragster go 130 mph in at the Houston drag strip. I'll bet those mini engines in the first post could do much better since they can be supercharged!
I am getting rid of that Kohler on my lawn mower and put in one of those! I love the exhaust on those things, talk about bark!
Hopefully, these can replace the 4-bangers in Honda's!
