I have to agree with this. My post also disagrees with the second post above. I took an orion r10 pro out of my T4 and installed the 120A turbo, and I was amazed at the smoothness. The ONLY thing the orion had on the trackstar was a bit smaller footprint. But the big money orion program box compared to the $11 trackstar programmer made the size difference a moot point. Might be different if you're trying to cram it into a super small mid motor buggy I s'pose, but the performance isn't what the esc lacks.

I forgot to add above another of the main reasons I didn't go with the genII for my 1/10 scale stuff was also due to the fact I like having a remote switch. If the switch develops problems on a wired switch, you just leave it on and never touch it, unplug the battery to turn it off. The gen II esc's that I have (1-cell) start out in the off position when you plug the battery in. Not sure if that may become a problem or not, the swtich does seem much better protected on the genII's. I'm going to have to buy a gen II 2-cell to try it out. My 1-cell units work great, and are smooth as I could want. And I race all my cars, not bashers.

Honestly it comes down to what you're used to, and your budget. If you like big name stuff, maybe that will sway you against it. But if you like the best bang for your buck, then these products are amazing. Especially if you have more than one racer or basher in your family.
