The hobbywing have a stronger startup but less ramp, so it will still go 0 to hero thus sensored system or transmission swaps the only way to get them to "crawl", without a sensor cable brushless motors dont know what direction they are going at low rpm and dont have the guts to move the truck thus, i swapped the transmission in our outlaw.
You can put in a big full 550 can low kv brushless, that will handle the lower rpm better.
But your spending the same amount to resolve an issue that it wont cure.
If you have a spare esc to swap out, do it the photons arnt great maybe you will have better luck with the hobbywing, i got sick of turning it off on on every time it stalled in long grass.
imo cornering is nothing to do with the motor, all outlaws roll over, you need to upgrade to a front swaybar and stiffen the front springs, also move the battery tray forward and lower to move the CG from being near the moon.
Have you also tried, resetting the end points on the esc?, check the throttle is at 100% and expo to before resetting it
