If you're concerned about having as low a weight as possible or want to have as low a CG as possible (if you're adding weight anyway), taping is the way to go. I think Erik has said you can remove about 20g of weight right off the bat if you take off the battery strap, plus removing it helps improve the L-R balance of the car before you even have to add weight.

If you can't get a file in the tape slot, use a Dremel. For a short-term solution wrap some tape around the slot so you build up a cushion. This will prevent the tape from breaking in a crash.

Also, I've seen a ton of Pro 4 racers having problems with their batteries coming out, or using the plastic pieces on the chassis that are meant to keep the stick pack batteries in place. Many times they aren't filing down the chassis and/or they are using the battery strap but the clip posts are too high. Just use the cross wrench to tighten the posts down a half-turn at a time until the batteries fit snug in the battery slots. This also helps hide those bent battery bars.

I also used those foam bumper tape piece under the batt strap which seemed to help holding the battery pack on there.

But now i use strapping tape

my remedy to stop the batteries flying out looks hacked but works. i attached a small peice of carbon fibre to the stick pack screw holes. this made a small extension, i then made a screw hole on this CF peice and used one of the servo mounts aS a stoper. i have the alloy servo mounts.

Has anyone tried the Tamiya toe blocks off of the EVO III on the HPI car? I thought i saw something about them fitting a while back but I can't find it.
ALso, does anyone know what degree of rear toe these blocks are? all I can find are the A, B, C, and D listing. I'm looking for 0 an 1 degree blocks.

I'm no authority on *anything*, but I have a 34 in for SoCal (rubber) and I wasn't lacking for speed anywhere that my meager skills could use. It seemed to pull great on the straights and I could accelerate out of the tight spots with anyone in my class (Novice), and it stayed really cool.

Now if I could just stop hitting stuff.
