Ok im new to nitro. Just got a used Jato with the 2.5, im running 20%or VP fuel, my local shop said to run a medium plug because a hot would cause overheating problems. I have had mine tuned out great and only once I hit a high temp of 250. How much hotter would a hot plug make a car run??
Hobby shops are not always correct.
Glow plugs have little to do with overall engine temperature.
20% fuel, hot plug, 2.5 engine: No problem. I like the LC3 hot plug with 20%
No slipper/tall gearing/power = broken parts.
Thanks I appretiate it snook man
