Cheers guys, thanks for the encouragement (always nice to get approval from all your experienced minds
)!
About the shocks...at first I was a little dubious too, but they actually shouldn't be a problem area. They're bottom-fillers so there are no caps to be blown-out, they have 3mm hardened shafts and they're fairly smooth. If I have any issues with them then I might look into changing them for some beefier big-bore units, but for now they seem fine and smooth. LST shocks won't fit unfortunately, but they would look pretty uber on there lol!
BrushlessBoy, the Havoc's wheel-mounting design is actually pretty solid (though it doesn't look it in the photos there). What you can't see in the pics are a large, aluminium wheel adaptors that key into the stub axles and then interface to the wheels over a large area using a proprietary design. It's a really strong setup, but it kinda limits wheel options...so at some point I'll probably fit Schumacher's optional 23mm hex kit. She'll also be getting a wheelie bar on there for sure (the stock rear bumper is cracked anyway, so it's not on atm).
I really can't wait to finish this thing...it should be an fun basher!
The one concern that I have is LiPo physical durability when I'm doing serious jumps, though I'm hoping that the RC-M battery trays will take care of that. And yeah, a 1515 will be a handful...but I'm told that the Havoc handles its horsepower really well for a RWD truck. Should be a lot of fun! I best get on with designing a motor mount...
