i wan,t to buy a realy small engine, so what is the smallest ic engine you can buy?

Cox made an 0.010. You can usually find one on e-bay. It is an aircraft engine though, and no throttle for RC.



Here's a typical e-bay link:

Norvel made an .049 rc engine.

Thats the smallest I know of (other than CL or cox).

The one on the bottom of this side is fun, I fly one in a small converted electric plane: http://www.himodel.com/sort.php?sub2=CH
