Yeah i bought the 5s just to see what it would do, i prefer to run 4s and i will be, so u think a 13t will do the trick? 48/13 will give good temps on the motor?

Hot motor and cool ESC/batteries usually means undergeared, but since you are geared kinda high, I would say gear down 2 teeth on the pinion (like big greg said). See if there is a change and regear accordingly.

[Mentat]

so my 48t spur gear is fine then? i can keep that and just fiddle with the pins to get the best result?

Generally, pinions are cheaper than metal spurs, but plastic spurs are cheaper than pinions. Depends what you have on hand and/or what is available for that vehicle.

BTW: To gear down, decrease the pinion tooth count or increase the spur tooth count.

thanks, i just ordered 2 pins for RC Monster. 10t and a 13t hope these do the trick

What temp gun would yall recommend? I need one myself.

This is one of if not the best gun on the market, U.S.made also.

Yes on the 8ight-t 1.0 a 15t/48t on 5s is more than enough iMO (40+ w/ tire bloat) on a 1515 2.5d (1650kv). Out racing on the track I often turn it down a touch on my Rx as well. To be honest 14t is the best gearing on a 5s setup w/ the 2.5d, but I didn't want to spend another 14 on a pinion right now, lol.

On to your setup.. I think 12t on a 2200 is WAY WAY more than enough, 13t is pushing it expecially on 5s lipo.. gear for 38-40 for racing, 45 for bashing and maybe a touch higher for some random speed runs only. Keep your MMM timings low to lowest as well, punch control should not be really high iMO (10-20% max).. as for the other settings having the drag break on will increase temps as well so disable it and learn to brake if you have that on.

Here's the temp gauge I use, had it for 2 years and it works very well and I'm still on the original battery.

i have 2 of those.

they read a little lower than the actual temp. when my savage was still nitro, the duratrax temp gun read 245F while my venom direct contact (loops around engine head or motor) gauge read 290F. i compared the venom gauge with a high-end temp gun and it is very accurate. with my brushless motors, the duratrax generally reads only 10-15F lower than the venom gauge.

Did you have the Emissitivity set right?

For temp guns I would recommend a Raytek MT4. I have used mine for years and it is spot on! They can be had on ebay quite cheap versus picking one up elsewhere.
