How do I use the IRTs to measure different RC needs?
Nitro Engine measurement: When temping out the engine of your Nitro car, you are looking for the highest current reading. That highest reading is typically going to come from your glow plug, and you can usually hit it from right over the top of your engine. Hold the “measure” button down on your IRT, and pass it over the top of the engine. Get right up on the engine, so that you are just about touching the head. Holding down the button gives you continuous feedback, note the highest reading that you get, that is the number you are looking for. With the higher D:S units, you can shoot engine temps from a farther distance. These units are good for cars with high riding bodies, or where the engine is buried down in there and tough to access. With a moderately warm Nitro engine, you are likely to see temps in the 180-210°F range. With a car that has been running hard for a while, you will start to see the engine creep north of 230 or 240°F. If you go much higher than that, you risk blowing
