Surpass Hobby 5 slot 16T crawler motor tested in FTX Outback Fury

We test a 16 turn 5 slot crawler motor from Surpass Hobby. All the hype says it should be faster and slower!? How waterproof is it? Can it cope getting stuck in the mud? After a mega amount of rain our usual crawling proves the ultimate test of man and machine as the going gets boggy, muddy, sandy and sticky all at the same time!
