I'm starting to understand exactly how important these things are to tuning and preserving the life of my motors so i am in the market for one now any suggestions I saw a couple on ultimate hobbies in the $30 range one is an ofna PCR themometer . Anyone have input as to the reliability or performance?
I don't think you need pinpoint accuracy or precision for our use. The temp probe is used as an aide to tuning. It shouldn't be used as the main thing for tuning. As long as its close you should be fine. And for only $30 I don't see how you can go wrong. It costs the same as the MIP on board temp guage.
I have a cheap temp guage that I got a few years ago at Fry's for $70 or so. At the time that was the cheapest one I could find. It has worked really well for me even though its a bit on the large side. I've been looking at the new small ones thinking about how easy they would be to carry around at the track.
The new one from TempGun is great. Very small, comes with a strap as well as a upright mount. Very easy to operate. You also get a metal case with an extra battery. Normally sell for 30 to 35 dollars. Check it out here www.tempgun.com
