Default TRX weightloss tip

My TRX need to loose some weight to be a competive scale crawler. What's the best tip to loose some weight?

I've changed the body on mine to a proline commanche body, got rid of the shift servos for the axles and made a custom battery mount.

I know the links are quite heavy, but what else?

There's a lot of plastic that can be taken off like the fender wells. Remove remote locking diffs and servos and install from lockers.

Maybe shave a few grams by replacing stainless/ steel screws/ nuts with aluminum... low stress areas like plastic, lexan, rx box, etc.

My rig is 8.2 pounds with no brass and I run a hard body. It’s SORRCA C1 legal and I took first place in both C1 and C2 (still on 4.19 tires) with it yesterday. Weight can be a good thing.

None of the classes have weight restrictions. They for the most part are about tire size, tire coverage with body, and bumper sizes. That is a kind of "in a nut shell" answer!!!! You can find SORRCA rules here: 2018 Rules are up!

Mine's 8.5 with brass. Got around 110 gram on each portal cover on the front axle. Got SSD portal covers on the rear axle wich is about 70 gram on each side.

Think my plan must be to get some titanium links, lighter wheels, lighter chassis (come on Brazin ), convert to single speed and brush less.

There's already brass everything for the TRX on eBay and AliExpress. No wait, not sure if I've seen brass tires. Male that almost everything.

Yes to losing rx box, but side rails help hold my body and I trimmed off about 1/2 the width, still works great but lighter weight and squeezes past obstacles easier.

Interesting they don't spec even on their own website lol. Pictures they have up appear to be Defender chassis though, therefore probably 12.8" wb.

I took a drill bit to the body mounts/posts and shock mount braces to shave a tiny bit of weight, drilling through where it was strong enough to take it and dimpling other areas it wasnt. I cut off the bottom of the body post that hung below the post mounts as I never plan on lifting the body any more.
It was a minuet amount of weight
