I seem to be having a problem w/ my engine on my Volcano, It's running really hot and I can't figure out why and when it gets too hot I can't start it, so then I decided to check the glow plug it was burnt, so I changed the glow plug and in 10 minutes the same thing happened it burnt the new one, I'm using medium glow plugs. Anyone else ever have this problem, it's the VX-18 Engine. It's only 6 weeks old. I also have the Tornado w/ the same engine on it and it runs great. One day it was running great and the next I have this problem. Any help and tips are greatly appreciated.
