i recently traded my buggy for a brand new ad2 with new servo's and a new sirio .12 engine. what upgrades should one do to start with? what size of allen wrenches do i need for maintenance? also, the person that built the kit over tightened the engine mount bolts, any ideas to get them loose? what websites have the cheapest parts? Tim

for the engine bolts use a dremal tool with cut off wheel to make a slot for a flat head screwdriver

the kit is solid from the box so upgrades are not necessary like most other trucks
