r/FCX24

fcx24m Tacoma. I got it today. I ran it for one battery And it ran great climbed some awesome stuff. Battery died, I charged it, plug it back in and now it is doing this. The back wheels are skipping under any amount of pressure which just makes the front wheels spin and it won’t climb anything anymore!! They also seem to spin much more freely, while the front wheels turn the motor over. I don’t know what’s wrong but it definitely wasn’t doing this before. I didn’t even drop it or crash it or anything. please help, it is my first crawler and it was so cool for the first 30 minutes :(

Retro white rims. How it looks?

Just got myself a used fcx24m Range Rover as my first mini crawler, honestly the best money I've spent on an rc so far. Iooks great and performs well and Im loving the second gear, looking forward to building this thing into an amazing trail truck :)

Hi everyone!
I'm trying to get my FMS FCX24 K5 Blazer over this specific rock, but it keeps struggling (as seen in the video). I’ve already installed a few mods, but I feel like it needs a bit more performance to clear this obstacle.

Here is my current setup:
Tires: INJORA 1.0" 56×23mm Swamp Claw (S5 compound)
Wheels: INJORA 1.0" Stamped Steel (-3.78mm Offset)
Shocks: INJORA 45mm Aluminum Threaded Oil Shocks
My questions for the community:
Is it even possible for an FCX24 K5 to climb a rock like this with the right setup, or am I hitting the limits of the chassis size/wheelbase?
What should be my next upgrades to get better traction and stability?

I’m currently thinking about adding brass weights (steering knuckles or portal covers) to lower the center of gravity, or maybe looking into a weight distribution tweak.

What do you think?

Any advice on suspension tuning or specific parts would be highly appreciated!

Hey everyone, i was looking at buying some upgrades for my fcx24 k5 blazer. I was looking at some injora wheels and tires but just wanted to know what you guys recommended. I also didnt know if the brass hex things, portal axle covers, heavy brass high clearance links and steering links were worth it. I didnt know whether to buy of amazon or get them direct from injora. Just wanted to know what wheels you guys think look good and what upgrades are worth it. Thank you!

I’m ordering parts for my long delayed Unimog build and I this is a good motor option. Has anyone had experience with one in a trail or crawling rig ?

I also think the transmission needs to be swapped and only see the trx4m listed with this motor.

Any advise is appreciated. Thanks.

Usted the alixprss Lightning kit (rack lights, front ambas and rear stop and ambars and added 2 3mm leds for the front bumper light buckets, some simple mods make it more enjoyable, mini ayrton at the wheel.

Hey everyone! How good are the stock tyres on the K5? Should they be replaced? If so, what tires would you recommend for traction while still maintaining the stock look?

FCX18 photo for show, but I am planning on swapping the brushless out runner system from my LC80 into my FCX24 Unimog and wanted to see if anyone has encountered any issues in the process.

I do see the parts between the platform are interchangeable and plan to use the tires, shocks and axles from the LC80 as spares.

I am thinking the wiring of the Unimog may be plug and play for the Outrunner motor and placement should be in the same location. I would also use the receiver from the LC80. My other issue is whether the two speed transmission would also swap into the Mog. I do not see any adequate aftermarket transmission options for FMS trucks.

Performance of the Unimog would be greatly improved and with some down low weight and some good tires, I’d have a good trail rig. Doing some research on this seems pretty straightforward. Does anyone have some pointers or tips for me?

I have the wooden flatbed ordered for the Unimog as well as some better wheels. I have the FairRC black mod.

My LC80 was ran twice before having power cutoff issues. I actually got a replacement esc from FairRC and then realized the issue is in the wiring. I’ve been through the truck as well as the tech at my local shop and it’s very poor quality wiring and still cut on and off with the new esc. That’s how I came up with the idea.

Any tips or knowledge would be helpful, I know the FMS aftermarket is lacking and rather than have this thing broken up on the shelf, I’d rather use the parts from it to build another truck.

Do anyone now any good tyres betwen 50-54mm for my Fcx24m?
