Questions?? Blackout XTE Motor/ ESC upgrade Options? 2019

Hello. This is my first post here and I realize this has been asked / answered before. However, it appears that the motor linked previously is now discontinued so I'm not completely sure what my selection should be. With that out of the way, I have a blackout XTE that i got for free, I swapped in some 7.4v 5000 mah 25c Lipo batteries and after my second run with the batteries burned the motor out.


I'm looking to replace the motor for a brushless design and ESC as a result. What are some recommended combos? I've spent several hours today researching but don't want to spend $100 on a combo just to have something burn out again so I've decided to turn to those who are more experienced.


I was looking at the following combo:

(Sorry, can't post links yet) QUICRUN 3650 Sensored brushless motor G2 Timing 10.5T (3600kv) and QUICRUN 10 Brushless ESC Sensored (2-3S). I assumed the sensored version will better prevent motor overheating in the future? My main concern on this combo is the current at Max output power of the motor is 62A and might damage the ESC?


Info that might help:
  • 7.4v 5000 mah 25c Lipo's
  • 18T Motor Gear
  • 55T Spur Gear
  • The XTE Pro uses a 3800kv Brushless motor
  • At the time the truck mostly sees grass duty.
I'm willing to spend around $100 - $130 for a good combination, so if my money would be better spent somewhere else (for performance and reliability) please let me know.


Thanks

P.S.
If you could elaborate as to why you make that recommendation or what makes it better I would appreciate it as doing so would help me understand the train of thought.

Take note on the length of motor and the amount of room you have to mount a new motor. That extra protective plastic cover, around the XTE's ESC, may need to go/be modified when thinking about some 3656, or 3660 size motors. I'm not quite sure on the amount of power the tranny can handle. Even though the Pro version uses a 540 size motor, I'd be shoving in a 550, or even a 3660 motor in there. Why? I'd want to make sure I had enough torque to turn all four of them big tires. That's just me. Different motors have different quality. Most 4 pole 540/3650 motors could get the job done...just gotta gear 'em right.

Just check to make sure of sizes on anything for possible fitment.

Thanks for these notes. The stock xte motor is a brushed 550 --- I didn't realize the 3656/3660 designation was merrily a dimension designation, so the XTE stock motor has roughly a 63.5mm body and only a couple mm to spare. I'm pretty handy with a dremel so the ESC shield can be easily modified.

From what I saw in research it looked like a lower kv would provide essentially more torque and less top end power. I did look at that motor earlier but had a couple reservations regarding it being sensorless and the shaft diameter (just ordered 2 more motor gears for 3.175, but not a big deal since they're cheap). Regarding gearing, is it really just a trial and error deal? IE; test different gearing and keep an eye on the temps along the way? Assuming I understand everything correctly, consider a new motor itself being "better" and the XTE Pro (same chassis) uses a 3800kv motor and 18T Pinion gear... By jumping to a 4000kv motor I can counteract that change by dropping a tooth in the pinion gear and see a similar powerband?

I'll keep researching options before making a purchase decision. Thanks for any help.
