Has anyone else run into problems with the green side springs? Both me and a buddy bought a set, and the top loop on the spring is too big in diameter, and doesn't click into the side spring retainer, it just falls off. Could this just be an issue with a certain run of springs, or is there something I need to do to make the springs fit correctly. All the other side springs I bought fit fine, except the ones I want to use.

What do you guys think?

I've had the identical experience with the green springs. They are too big for the 12R5.2 spring retainers. My fix is to use the original plastic spring retainers (#4640) which fit a little more snug--though still a bit too loose--and then hit them with a spot of CA to affix the spring to the retainer. They become a permanent unit that way, but the plastic retainers are cheap so no big. After that, they work fine.

You can just make the top loop smaller by pinching it with a pair of pliers.
Carefully.

Associated makes a Aluminum screw kit #8558 that should lighten it up a little bit!

Shorten all wires
Like Joe says, the aluminium screw set will save a lot
Airbrush your bodies instead of spray can paint
Tire's can really make a difference (size and rimm)
And if all this doesn't work, some of the guy's even remove the casing's of all the electronic and replace it with shrinkwrap.

Regards Robert

Default 12r5.1 Modification

Hey everyone, I'm wandering if anyone has come across ordering a drill bit to make new holes into the carbon chassis fitting 3mm flat head screws. Any info on part no. or the bevel angle on the flat head screw is greatly appreciated. I tried looking it up on granger.com but lordy, it's taking me forever.

You can manage to lose weight by using a pack in the 4,000 - 5,000 mah range.

I've hardly ever used more than 1,900mah in an 8 minute heat.

What does shimming the front ball on the side links do? Also, the damper tube ends?

Thanks for the info guys!! Although I'm a little concerned about the durability/strength of the aluminum screws, I'm going to give them a try. I believe this will yield the biggest loss. Also, I'm switching out my servo to the Sanwa SRG-HR and will be shoegooing it directly to the chassis. I'm hoping that by removing the mounts it'll reduce the weight even more. My bodies are usually a one color spray bomb. I'll have to consider either getting custom paint work done or invest in a air brush system. I would like to explore and try all of my weight reducing options before going to a smaller capacity pack for the obvious reasons.

Regarding tires, I'm currently cutting/truing them down to 43mm (rear) and 42.5mm (front). I've bought some Parmas and will start to cut/true them down to a 41-40mm range. I tap the board time to time but I'm not a complete hack. I hope that cutting the tires down will get my tire chunking issue under control.
