It will need more work but the waterproof XL5 I just purchased from shizzon will go well in it. I plan on having it fully waterproofed and able to submerge. I like the small scale aspect of this and the losi MRC platform has gotten great reviews on rccrawler. It has a more scale type chassis on it which is a bonus too. I plan on making a nice little flatbed setup but haven't gotten beyond that. Any ideas from anyone???????
