I have a crash and the first two fins on the blue head are dented. Will it affect the engine if I leave the bend like that?

No not really. It should be fine.

I'll take it
I'll give you 10.00 for that OS

Which way is it bent?
If the fins are bent but air can still travel in-between each fin I doubt it will matter much. If its bent on the carb side and blocking the fan flow your guess is as good as mine.

Got a pic?

If you're worried about loosing cooling from the dented fin, you could run a tad rich and go from there.

I've been running my rebuilt OS with bent fins for a while...

They bent after a nose first incident.

The fins at the bottom of the head are bent to the back for the heli - not completely touching but close. The engine runs fine with it like that - no difference.
