There have been mixed reviews on the issue of MGM's "speed" of service. For me, it was 6 months before I saw anything from them, and they never replied to a single one of the 15+ emails that I sent them during that period.
SH Z-Car, Custom Crawler, 8s Savage, 12s XTM XLB 1/7 buggy, 4wd 4-link rear/IFS Pro4 truck, Custom Hyper 10 Short Course, Belt-Drive Mammoth ST 1/8 truggy, 4s 17.5 MM Pro HPI Blitz
Actually, I think spending three days messing with something that I have a LOT of experience with is sticking with it a little TOO long.
Believe me, I tried everything. I wasn't just going to send it to Europe without exhausting every possibility.
Let me say that this is a very good speed controller. It took awhile to get it programmed, but I like the features. I set it up the way I wanted, then I let it automatically program itself. After its first run, I shut it down and restarted it. The settings were still there, but it had adjusted itself perfectly.
This thing ran until the batteries (Pro-Match IB3800s) gave out. No thermals. Not even very hot. It kept taking abuse all day. I am very impressed.
When my 16020 returns, I'll test it once, then shelve it as a backup. The 12016 is more than enough for my 13-pound E-Maxx with 7" tires.
