Dynamite Mach 2 .19 Engine...any good?

[towboss]

Ordered one cheap off eBay, but don't know much about them. Any feedback?

My only dealings with Dynamite is the tool sets (nut drivers) and the Bigred engine. Very happy with the quality of both and the engine is probably my most reliable nitro engine I have. Holds a great tune and seems to be a solid quality product

The main bearing is an issue and should be replaced right away, other then that it's a decent engine.
