Hi, I am a noob to nitro RC, and I recently bought a Tmaxx 3.3 on craigslist. I can hear the engine going put-put-put when I put the EZ start in, and the flywheel starts spinning. This happens as long as I hold the red button down. However, I cannot see the glow plug getting orange (am I even able to see that) through the top of the engine. (It is a relatively new plug.) Any ideas on what the problem might be?
