Here's the final result!
It's not as bad as the previous one... but not yet perfect...
I followed all your advises and after inserting the silicone I put a drop of engine maintenance oil on it and with the tip of a zip tie I molded the silicone in place. (It's much easier with the oil... )

I think the outcome was quite reasonable... do you think it's worth a try on a working engine?

Thanks for all your help!

That is better. Try to make the angle less steep. More of an angle (less vertical)will create less turbulence, the gas will flow easier.

I'll keep that in mind for the next crankshaft...
Thanks for all the help!
I couldn't have done it without you guys!

PS: this crankshaft was just for test. I'll try it on the "new" Mega ZX21 crankshaft (the one without the inserted conrod pin) and I'll post my "on-track" experiment (if the engine doesn't eventually fail )

Sorry, I didn't understand your question...
There's nothing wrong with the crankshaft (it's the original crank from a Mega ZX21 with the pin inserted in the crank - which usually breaks). The crank was drilled and filled with silicone in order to make it lighter.
I'm not sure if this answers your question, but...

Default Art Carbonell wins International Puerto Rico RC Event with Murnan power

Puerto Rico RC Events hosted a great race at their Carolina track this weekend. Racers from the USA & PR attended. The event turned out great! Local hot shots and international drivers waged an intense battle for the top spots in qualifying and the finals.

After an intense 45 minute final that featured rain, tire stops and very close racing Art Carbonell ended up on top. Art's equipment:

Mugen MTX-4
Murnan modified NovaRossi LS3
Enneti Tires
Maxy Fuel

A big thanks to everyone in PR for their great hospitality and fun atmosphere.
