No, I don't have a temp gun to check. I was able to use the entire 3s battery and at that point I couldn't put my finger on the motor cause it was soo hot. I forgot to time how long the battery last, but maybe around 30-45min. It's too tight on the esc so there no way I was able to touch that. What other type of gears can I do for upgrades?
finger test doesnt cut it for figuring out what is top gearing. anything over 130 is too hot to keep you finger on, yet that motor can run 160 without damage. I have run a motor upto 190 without damage. 160 is a safe range. I like to keep the ESC alittle cooler...140ish.
Im not sure how big of a pinion gear you can fit on the caldera. but when it comes to gearing up, 2 teeth can make the difference of 2-5mph.
but dont gear up untill you know how hot your ESC/motor are running now.
