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
