Description

this is a remix of ex-pigeons design and its a Trx4m lcg chassis for the bronco and defender (only tested on bronco)

this is an awesome chassis that can completely change how your crawler performs it improves how steep it can climb, improves the flex by a lot, and it's very simple to install,

you can retain all of the stock parts, but it works better with longer shocks, the stock shocks bolts just screw into any of the multiple holes no nut needed, I've taken the springs of my shocks to improve flex but you can keep the springs on,

no supports, i printed in petg but pla should work fine 

 

you need a few extra bolts to assemble

M2.5 x 15mm, total 4 pieces

 M2 x 8mm, total 10 pieces

M2.5 x 8mm, total 4 pieces

m1.4 x 6mm, total 6 pieces

 

13/05/2025, i have now made extension arms so that you can use the chassi on the hightrail models, you can find the extension arms on my profile here Trx4m chassis hightrail adapter
