Just wanted to say Thanks to RcTech for all these years of Great Information.
the SX12 is probably one of the best GM speedies around. If you have the GM commander charger you can use it to program the ESC. That is the feature I love most about the SX12. It is more updated the V12. Check it out. Everything that I have bought that is GM is top notch equipment except the battery case (not there faught) because it is just a re-badge of some elses design. But if you buy a GM Speedie it will give you what you crave. I have used the Quatum Comp2 for awhile and I love it but the SX12 has a better programing for stock and 19t which is what I run most. Now for the MOD motors the GM has a very high continuious amp rate.
