Broken Heatsink

[obochoman]

I Just purchased a used Hpi nitro star G3.0 from friend for dirt cheap. I was able to get the thing to run but it is not tuned yet. The only issue i see with it is that its heatsink is broken; the top couple fins are broken off. Does this make the engine unusable? I don't want to pay for a new heat sink that will run me $30 when the engine new costs $80. Can I run the engine with the broken heatsink without issue?

thanks

If just a couple of fins are broken off it shouldnt be a problem post a pic

Yep, tune it and run it and forget it.

Cut it off and smooth out any jagged spots, it'll be lighter and more aerodynamic...you should gain a good 10 mph. Seriously though, I'd just cut it off, one little fin won't hurt it. It's the hit that broke that fin that I'd be worried about.

Not a problem at all. I just filed down the edges on my picco .26 max from where the entire top fin broke off. Its been holding on by just two pieces for a while now and a rollover yesterday took it off in one piece. Ran her today for several tanks in 86 degree heat and temps are fine on engine still.
