Default HBX2098B - My Rig.

I have a somewhat modified HBX 2098B

It's got a few aluminum upgrades.
Driveshafts, front/rear axles, and uhm. Tires, Steering linkages.
I love this thing, tiny, perfect for indoor winter time rc-fun.
4 wheel steering, and 4 wheel drive, plenty of articulation.







I suppose the best upgrade you can do to this thing, are the new tires. The stock ones are really hard... Getting new soft grippy ones makes a huuuge difference. The fact that they are slightly taller, and less "fat" also helps a bunch..
The aluminium upgrade parts, are mostly for the heck of it.
All the parts needs to be lubed with grease, even the driveshafts..
and the front/rear axle housings in aluminium, are of less than perfect quality, some parts are not made to spec, and they required some "run in" with a dremel at 25k rpm for a bit, to become "smooth" :P

If you decide to do that, note, plenty of lube, and to make sure it doesn't over heat the plastic parts in the diff.


The supplied screws to hold the outer hubs/cv shaft housing to the axel housings where too long, and would actually screw into the driveshaft itself..
These are tiny screws... I didn't have any, but I just sanded them down on a grinding wheel.
The steering linkages, did not come with enough bushings, and the stock bushings are not long enough, meaning the steering would lock up if you tried to use them in stead. I pm'ed the seller, and he sent some extra bushings, so now you can tighten all the screws to a decent torque, without the steering binding up.






I also used a lot of locktite



Them missing bushings...


Meh, it's a really fun, and CHEAP toy..




At less then 100$ shipped...

Honestly...that car is the only "micro" I would ever consider buying. They are super cheap in the moment and maybe one is under the tree ...who knows?

Cool to see something else than the scx24 and trx4m. Iíve actually also thought about picking one up. It has some very good features.

I just wanna say, that if you need spare parts for one of these, aliexpress or Banggood is your friend. There are not that many parts on Ebay.

And yeah, the features are great, 4 steering modes, front, front/rear front/rear in parallel for crabbing, and rear steer.
It has really low range gearing, so it can crawl slow, with enough torque to go just about anywhere the motor has a reduction gear built in. there is also some reduction in the center gearbox I believe.
It has 50/50 4x4, locked center, and front/rear diffs, and due to the gearing, it will hold itself at any angle and never roll.

It comes stock with proper, working beadlock rims, I've had at least 3 sets of tires on them

Upgrading the motor is a bit of an issue, since it has this reduction gear set in the motor itself. I would think just putting another same scale motor in it would result in it being way too fast.
Like for example a brushless motor off a mini-z or similar. I do have a "Rocket 3500kv / 18A ESC combo, https://www.surpass-hobby.com/index....product_id=198 I could try, but I presume it would just fly with that thing on. It's rated for 60 000 rpm I think :P



^That's a lot of reduction...
I wonder if I can just transfer that reduction gear onto the brushless motor I have ? hm....

It also uses 4 wire servo's, and those are "impossible" to find upgraded replacements for. Should you want any.
