Yes read up in the other thread, tldr you need to craft a 5mm bar into a drive shaft that will take the ring pinion, requires a dremel and lots of fine grinding work. But is doable, another guy used 8mm bar as he used 8mm bore pinions and lathed his down. Are you running 4s? i used hobbywing Xerun XR8 SCT on 4s and got 100mph on stock drive train with trx4 plastic spurgear it was paired with a Hobbywing Xerun 3660Sd D5.00 4300Kv G2 motor or a castle mmx 6s esc 2400kv motor.

bump before ebay gets it

Castle Monster XXL ESC+ Hobbywing 4985 1650kv Motor Combo. Selling this as no longer speed running my hyper 7. Both used at Rossa for speed runs (about 5 passes) Note the castle esc has got a crack in the plastic case but doesnt affect cooling or perfomance. The motor has had the bottom fins ground down to allow it to fit into a hyper 7 on stock mount. This doesnt affect performance. 5 speed run passes with these, ESC was NIB Purchased at ROSSA 2022 for £180 Motor was purchased 2021 never been in the wet, bearings all smooth, cable got nipped by lexan so heatshrinked to reseal cable. Looking for £220 this inc fees and postage as a combo only, wont split, cost covers postage as the motor is big and heavy. Any questions please ask. Thanks for looking.

this is a specific low cg build designed for hardcore crawling, the trx is more of a trail truck, built to withstand what kids would do to it, a pro low cg setup like this in the hands of kids will be destroyed pretty quick. anyway looks like a decent bit of kit that competes with the likes of the custom lowcg element chassis, trx4 isnt the market for this cars competition, element and vanquish are imo.

I run a 7.4v servo so have my axe esc in the trx4 set to 7.4v still using stock rx gear so yes it can take it.

Looks good! like the winch nice touch, dont like the servo on axle but looks pretty tucked away. Ive been liking these newer ones, always enjoyed my highrock.

Thats a very nice body m8, there was a sweet ute body from hpi id like to try but it wouldnt be any good for speed running, just looking sick haha.

Another horrible body what are they smoking. The sharp corners will crack on roll overs. Smh

Its a crawler it will be fine. The id connector wont function but the connectors should right? Got a pick locky of your adaptor and the esc connectors?

I eat my words, This actually might work, it might not sleave over the fancy female connector but the esc should have male pins that would fit into this connector.

Chop the traxas connector off the esc then put on a tamiya connector. Never seen adaptors for those, i dont think traxas would permit it. So yeah cut n shut. You selling the lipo? Dont cut off its connector.

This would be on 4300kv 3665 hobbywing xr8 4s setup. Gearing was traxass spur gear 32dp 34 - 38t or something with 24t pinion from the looks of it, sadly i dont have the exact details as i run 34 pinion and 24t spur now, both of these are pinions and requires a custom drive shaft mod to use.

The body hurts my eyes and thats nothing to do with the colour. Really needs some inner fenders to fill up the massive wheel arches. The window and handle scales look really weird, as does the front, like they smooshed the front of a Jeep with the back end of a FJ Cruiser. Drunk they must have been very drunk.

You dont see a cooked hobby wing often, what a mess, how are the batteries, if the esc popped it might have started a short on the batteries, check the cell voltages Most of the time these ESC's will cut out due to high load (amps) (not heat). The max 6 only uses 10 awg wire and should be 8awg for 8s imo, the current melted the connector from the pcb. But the fire probably came from the capacitors blowing out, tho the tops look okish.

Love the buzz from a new PB. Grats m8
