In past i had Nomadio receiver in same place and it failed because some stupid rock stucked between PCB asnd RX body and screwd copper traces. Actualy when i opened it it was full of dirt. Now RX in custom box same place and when i look on that I see sand and rock marks on it.

Durability
 

The Muggy is very durable. I've had very few problems running at about 13.5 lbs on 4s. I have RPM arms all around, they are much better than stock. The front bulkhead seems to work loose and pull out the screws that hold it to the chassis. I drilled it for oversize screws and no problems since. I do seem to break front shock shafts (3 so far) in collisions. I've bashed, raced, jumped, cartwheeled, and hit all kinds of heavy objects. Overall, it's a seriously tough truck and lots of fun to drive on any terrain. I am curious about the Savage, it's a real animal from the vids I've seen.

how much runtime do you wreckon you can get from a 5000mah battery?

It's very nice, the more I see these the more I like them. it has everything I liked about the lst and none of the stuff I didnt like...I want one. By the way the clean installs make all the differance in the world great job.
