Thought i'd share as it seems to work well. 3-4min warm up & i can't touch the engine for heat ! It cools down within a minute or so. Don't have a temp gauge though would be intersting to know how hot the engine gets.

Just finished running in a new engine using it & it never failed to start on the 1st pull.

I know you'd hardly sell one looking like this, lol, but it was cheap as chips :D

nice idea, i used a hair dryer for my cen nemesis, but never worked as well as i would have liked.. your mod is a great helper when breaking in tight sleeved engines.
would be nice to know what temp it gets too??

i like this:thumbsup: and im going to make one :D cheers for the idea

Clean it up a bit and put some high temp paint on it and count me in. It looks like a great idea to have one since I'm just getting into nitro engines. Might have to pick one up for the tool box!
