So I Have a Muggy Now!

[Unsullied_Spy]

A 1521 is more powerful than that motor^

Plenty of power on tap won't be a problem for a 1521, keeping the tires in 1 piece and keeping the front wheels on the ground will be. Throttle control is everything and having power to spare is nice, so if you can keep it tame enough to use then that's a great motor! The Muggy is a very tough truck. If you put the diffs in the LST aluminum cases and keep them well-greased they put up to a LOT of abuse and despite how hard I've beaten mine the entire drivetrain is still solid. The only failure mine has had so far was the front diff because the plastic case cracked and let the ring and pinion slip.

A stock Muggy with RPM arms and Lunsford titanium turnbuckles in the arms is almost indestructible. The aluminum diff cases and the new arms are really the only things I've done to mine as far as durability and despite being beaten mercilessly on a constant basis it continues to hold up to the abuse very well. The Muggy is an excellent truck, after seeing mine my LHS has finally decided to start stocking them

Well i got my battery yesterday and decided to give the 1515 1y a chance so i could at least see it run on 6s, i got a 11tooth pinion which was the smallest that would fit without center brace trimming. well i was suprized how great it ran, peak temp after hard grass running was 168 wheelies to no end. i can copy unsullied spy's back fip no problem actually it was the first thing i did after i saw everything was rolling smooth. its faster than it can be controlled top speed and im very happy with my build. battery temp got up to 110 with turnigy 30c 6s 5000mah. mamba fan ran alot but that is to be expected. its amazing to see something so heavy flug around like a ragdoll. the only problem i have is over excessive tire ballooning in the front even with 100k in the center. but i have some spiderwire fishing line im going to wrap on the tires to see what happens as i ripped a tire open when it ballooned and hit the body. but i replaced it and still have 2 more spares
