Don't be afraid to ask this question of some of the guys in the UK....there the ones who will have much more experience with Mtroniks. I've heard good and bad about the M3. From what a couple of UK drivers have told me, it was pretty advanced stuff that was put on the market too soon. The Cirrus has supposedly fixed all the M3's shortcomings and is reported to be a great unit.
I once thought GM had a great reputation, but after looking at many of the UK and German forums, It appears the SX-9 is NOT the one to have. Apparently even Horizon Hobbies will not replace a bad SX9 with another one....they'll send you an SX12.
I'm gonna try the Mtroniks. Good Luck

RCGT all the way !!
SX12 is an excellent speedo......they had problems with a low thermal shutoff on the SX9, so they discontinued it quickly, and are replacing it with the much better sx12......I think that is a respectable move by GM. Some companies would just continue to sell a bad product.
The SX12 has great specs.......
.00025 resistance (over half less than the GT7)
no motor limit
I've seen 2-3 MTronics low end ESC - very strange behavior from time to time. Personally I wouldn't spend money on them. I dont know of the high end stuff though.
There's a GM V8 and V12 in our club - people are very happy with them. One thing I rellay like about the GM, is that it's the cheapest ESC I've seen so far, with a 6 volt BEC. I've read somwhere that GM's not the easiest to program. But I havent tried it myself though.
