I used the 9920 on my 8XL/16 cells powered savage. I did use a fan on it though.

Sounds like the 12020 is better. Can someone tell me where to get one and how much. I would have liked to buy one here but they are not sold here anymore.

It's not said the 12020 will be cooler than the 9920!

I just saw the MGM 16016 (160 amps, 16 cells). Is this a good speed control for my application? Also, if I used the heatsink motor clamp, would I be able to use the 7XL and 16 cells? Assuming the same max rpm as the feigao (50,000 rpm), and a kv rating of 2145 rpm, it should handle just under 24 volts. 16 cells is 19.2 volts. I have heard people used this with 5 series lipo.

The Feigao/wanderer series are most happy (cool temps) around 35,000 rpm. With that voltage, a 9XL would be a better choice. In another thread, MGM is coming out with some very nice new ESC's, so it might be wise to wait for those. :)

Not to mention the stress it will put on the drivetrain; plain simple; it's about the power/weight ratio. one single XL motor is more than enough in terms of power/torque to launch your truck at warp speed in the blink of an eye.
60mph might sound cool, but it takes quite some expensive upgrades to be a solid ride..
Te dynamite chassis is poop, it's a cheap molded chassis. (gpm quality) get the FLM instead, you can put cells on top and bellow the chassis as well. there are special braces available that make it work.

Well said. And yes the Dynamite chassis is POOP! Do the FLM. At speed, the added length (not to mention strength) of the FLM will be a HUGE benefit! If your shooting for "WARP" speed the G-Maxx chassis would be even better.

Sleebus: I don't think I would spend extra on the latest speed control if the older model would work. I do not race, I just need something to get the truck running and not let smoke, the older MGM is good enough for me.
Procharged: I do not like the G-maxx chassis because the low ground clearance, my supermaxx towers already lower this thing almost to the ground. Also, everything I hear about G-maxx is that they make great products, but they are easy to bend and not for bashing. Besides, I can't afford them. Fastlane machine is the way to go for me.

The FLM chassis is nice! I own one myself, and for similar reasons.

I already did this 8mos ago w/ my BL Revo. You will get ~45mph w/ the 8XL on 16cells.
Now this is alot of power, and its very fun to drive, but if your big/only goal is to do 60, then you need to ~2x the power. On 5s Lipo/8Xl/MM i did 48-49 mph reliabiably. My conversion parts were light, but this was a stock 2.5 chassis and talons. Dropping weight I could see 50-51 I'm sure. This is the very edge of what a MM can do.
To get to 60, I would say you need ~2500+W for an avg/light Maxx. My 5S setup was ~1800W realisticially. As speed goes up, each increase in power shows diminishing results.
You will need an expensive drivetrain to do this as well. G/l trying to keep the front down. The MM cannot provide enough power unless you get your truck to insanely light weight (~7.5 or less I would think, but just a guess.)

An MGM/Neu may do it. I would try to run as much voltage as possible with a low kv motor and gear tall.
This is not a budget project btw. Face up to spending the $$, or realign your goals w/ your budget.
Making a 60mph truck does not make sense for bashing either. Dragsters do not make good daily drivers. Low 40s is plenty for bashing. Trust us, we've done it, we know. I barely even run my 5S batts, and that's only on the street for speed runs. Even 35 is fast on rough bashing sites like contruction lots.

Johnnymaxxima used 2 7XL motors on 5s lipo to each. Would the same motors with 16 cells to each, full metal transmission, supermaxx differentials, and MIP cvds geared 24/51 be a setup to reach 60? I really do not have the money to get lithium. Is the extended center driveshaft that comes with the Fastlane Machine chassis compatible with supermaxx differentials?

xmods, what you're stating with a dual system with 32 cells (not to mention the supermaxx diffs) sounds expensive and heavy, and not efficient. if you're dropping that kind of change, i'd take the suggestions/advice offered and go with a single, good system.
i would also go with supermaxx cvds and not MIP. they're only $10 more a set, but are much more durable.

Dude, your talking FIVE AND A HALF POUNDS of batteries including bars, and solder. All in all probably TEN POUNDS of truck or more. I don't think you'll see more than 45 Mph with any motor that will actually fit in there.

Nope, one single setup is the way to go; but i think he has got no idea what power is waiting.. :)
Here is what lightweight does with 5S of poor quality lipo's. Good lipo's will give you about 20-25 percent more power..;
