As has been mentioned, I built that Muggy, although no mods took it a couple of steps further and actually made things nice. He really made good use of the voids in the rear bulkhead for the electronics.

I don't think that the Muggy is a good racing candidate by any means. It handles OK on the track, but nothing like a true race truck. Of course, a really skilled driver could probably surprise you with it. I saw a guy at our local track show up with a MGT with MT tires on it come out and whip everyone's butt. I'll list the reasons why I went with the Muggy.

1. It has a center diff. I think that the center diff is leaps and bounds better than a tranny. It serves to relieve some of the stress that the drive train endures by unloading to either the front or back as needed. For this reason, I wouldn't lock up the center diff. Locking up the center diff will also substantially affect the handling. It's great for crawling, but not for hauling butt. I ran 100,000 diff fluid in the center and liked it. I like the center diff better than the tranny because there are fewer parts to break.

2. It's easy to stock parts for the Muggy. The front and rear arms are the same. Front, rear, left, and right interchange. Parts are also pretty inexpensive and can be had on ebay pretty cheap from people parting out new kits.

3. The truck is big. I don't mean this from a standpoint of the stature of the truck. I mean that all of the parts are big. Everything from the knuckles, to the shafts are big. They look like they were meant to run the big 40 series tires and wheels. The Muggy shocks are what I loved the most. Boy, are they easy to rebuild and maintain.

4. The truck is tough. I put mine through some pretty wicked stuff on the track. It did very well for a truck that went 13lbs.

As far as back flips from a standstill go, it was easy to flip it onto its lid and have it bounce back onto all fours. It's really no great feat for a brushless setup. I saw no mods' video and the truck does look fast. I don't want to downplay what no mods did with the truck, but I do have to say that it's probably only getting about 35mph in the video. The truck is big and is good at climbing over things and eating up rough terrain, but it's no drag truck. You really should try to keep things sane. If you try to make it fast, you'll likely start breaking stuff just from the stress due to the weight of the truck.

Things really didn't come together for me until I went with the 9XL motor geared about 12/46. If I had it to do again, I'd go with a 10XL, or better yet, a 12XL on 5S lipo. I'd run the 5S2P 8Ah pack. The truck carries its weight very well.

There are some things that I had to do, which were already done on no mods' truck. First, I went to an aluminum center diff cup. It seems that there was such stress on the center diff, that the screw holes in the cup would strip out. Second, aluminum (the milled stuff, not the cast) front and rear diff cases. I cracked two sets of plastic cases simply because of the torque due to the heavy truck and the huge tires.

I'd also setup the truck with a motor/esc combo that would allow me to run pinions in the larer range. 11T on up. When I was running the 9T pinion on concrete, I would sometimes strip the spur gear when landing after a jump. This only happened when I had to apply brakes to level the truck during the jump, but I think that the larger pinions afford more gear contact and prevent this from happening.

As for the motor mount, I made it myself. It simply bolts to the center diff bulks. Since I was going that way, I used the optional Sportwerks aluminum center diff bulks. I then drilled out the treads that were there for the brake disks and counter sunk the holes, so that the screws passed through the diff bulk and screwed into the 1/4" aluminum motor mount. This made for a VERY rigid mount and also served to move heat from the motor to the chassis.

If you are going with Neu motor, I'd be sure to go with a controller that can handle the Neu. The MM required undergearing with the big truck. As you can see from no mods' vid, the Quark helped substantially. He is running a taller gearing than I could have. If you get the Neu, I'd go with a 1700kv motor or less. With the truck it's going to be better to go with a low kv motor and gear up, rather than get a hot motor and have to gear down.
