I recently purchased a GS Strom Pro that has been fully assembled & just barely broken in. I am new to Nitro RC & have been doing as much reading as possible. It has a RB Concept 1003-S7 engine & it came with an infrared temp gun. When do you check the temperature for tuning purposes. Do I check it at idle, at higher RPM's while running on a stand or something, or do I check it after coming back from ripping around at various RPM's (typical use). I ask this because at idle it seems to run quite a bit cooler than when I check it immediately after ripping around and driving it up to me and checking it while it continues to run. After it idles for a few seconds it seems to continue to quickly cool down. I've seen readings as hot as 240 or so but it quickly cools to under 200 as it idles. I think I need to keep it in the 200-230 range but at what RPM range, is this a max temperature range? Help, any info you can add would be much appreciated, thanks, Mike. P.S. On a less important sidenote, anyone know how to quiet down this thing when I want to start it up or run it in the neighborhood, it's got a Omega Efra 069 pipe on it.
