I have them both.


The new MGMs are really nice. I like them alot. It runs alot cooler than the Quark. USB programing is really sweet. You can change all of the programable ESC prameters with it easy as pie. However, dont put to much positive on the USB programing thing. Its nice at first, but once you get it set where you like it you pretty much dont touch it any more so the USB programing thing really isnt that big of a deal IMO. But the thing that the USB does do, that is a big deal IMO, is the ESC actually has a basic data recorder built in it which is really nice to have. It records the Peak Amp draw, the Voltage of the battery when it was unplugged, the Max Motor RPM, and the max temp of the ESC. Damn good info to have and you dont even need an outside device to collect it. Also the fact that it has a built in Switching BEC for up to 6s lipo is huge IMO. One less thing to wire. Gotta love that.

Now the bad... The reverse/brake thing is annoying, but at least it alot better than MGM used to be. It only does it a very low speeds so its not going to damage anything like if it did it at high speeds. I wound up disableing reverse to eliminate the problem just cuz it bugged me. I really didnt use reverse anyway. The other thing is the shape of the ESC is rather hard to mount well IMO. The flat bottomed, hard case of the Quark is very easy. The MGM with heat sinks on both sides takes more creativity, but that little thing is worth it to get the extra heat sink.

There are extras needed to purchase with both the get the most out of them. The Quark NEEDS a heatsink at a minimum to run well, and many need to be taken apart and heat moded. The MGM needs a special USB data cable to program it via USB and use the data recording feature. Neither one is a very expensive item, but they are extras you will buy on top of the base price.

If I were to buy another ESC I would for sure go for the MGM again. But thats just my opinion. They are both still very good ESCs, and I have both in service right now. Its just a matter of what minor issues are more tolerable to you and th Quark heat just pisses me off.
