MJX H8H Is The Most Versatile RC Crawler EVER!

[@FeralRC]

The tire tread design is basically an exact copy of the Traxxas Canyon Trail that comes stock on TRX-4. Also I can't help but notice a ton of similarities to the CrossRC Emo X line. This includes that rear lateral arm suspension design. That's certainly a good thing as the Emo X has been an excellent product and we run our original X and X3 all the time. If a brand is going to mimic another then it's good to see it be a high quality brand.

[@DoRC]

Definitely very similar! I didn't notice that. I was thinking more of aftermarket tires.

[@Boogie_the_cat]

Wait, EMO? Emo? Is that the truck that My Chemical Romance and Fall Out Boy drive? PS, I hate myself for even knowing those names but I dated a goth chick once, so I know, I just know damn it.

Not really bashing, not really crawling, not really crashing, guess you were brawling? Appreciate the tear downs and seeing what you get for the money. And the FOC system is interesting, performs well.

[@DoRC]

Yeah I like to call it trail riding or trail bashing. It's what these vehicles are really good at. Kind of just bombing around in smaller areas. I guess maybe rock racing would be a reasonable term? I don't know. But yeah the brushless system in this is the best I have felt in this type of vehicle.

FOC motors are also supposed to be quieter than standard brushless motors. Less whine.

[@DoRC]

This one's pretty quiet though the non-foc hobby wing sensored motors are also quiet. The castle ones are pretty whiny though.

Nice video!! Truck looks cool. I had a buddy that had a Traxxas Summit, it was sort of a crawler/basher type of truck. This video reminds me of that truck.

[@DoRC]

Yeah this is more on the crawler side of things and the summit is more on the basher side of things but they do kind of have a similar feel.

[@DoRC]

[@jasonwolfe1305]

Just FYI, that thing on the rear axle isn't an anti-sway bar. It's a Watts Link and its purpose is to help locate the axle laterally so it doesn't move side to side while the vehicle is moving.

[@DoRC]

I'm not sure I quite agree with that. First of all the suspension already is four linked which means it's constrained laterally and the WattsLink geometry is a little bit different. What's links tend to always have the bell crank on the axle and the other end of the arms attached to the chassis not the other way around. It's possible they had the same goal in mind with this but since the pivots are So far out of alignment I'm not sure it would really achieve that goal and I don't know why they would do that since it's already four linked. In feeling it it does seem to give anti-sway tendency with its geometry but You could be right. They may have been going for a WattsLink setup but they certainly didn't set it up the way that it normally is.

[@jasonwolfe1305]

@@DoRCit’s definitely implemented opposite of how a Watts link normally is. Is there any kind of spring in that central pivot that resists rotation?

[@henrysimas4747]

@@DoRC at first I was thinking of the WattsLink setup too but I noticed it was backwards and useless since its already 4-link It could be a sway bar but why not just make it like a traditional set up I think it would be cheaper to make and more efficient. You might be right in thinking it helps with articulation.

[@DoRC]

@@henrysimas4747 Yeah that was my thought too. When I first Saw it I thought WattsLink but then it's not set up like one and I guess it could still be working like one but I've messed around with it since then and I'm honestly not sure what it's supposed to do. I think it's entirely possible that whatever they intended it to do it's not doing :-)

[@Baker_7498]

@@DoRC in theory it should be giving more lateral support to the axle and also raising the roll centre which would make the truck roll less in turns and side hills

Yeah it took some pretty gnarly hits in my testing so I think it's at least reasonably durable.

[@dc9808]

Best looking land cruiser type body I have seen, looks great. They left out dig ... I think for $200 less the 1/10th scale fms K5 is the winner here. Although having brushless is a big plus. As always nice video. And that body does look tough!

[@DoRC]

Yeah I think it just depends on what size you want. This is significantly larger than the FMS truck so that's a big advantage too.

[@lyricofwise6894]

The scale size is meant to be in between that and an axial scx6, but the price close to former since scx6 costs $1100

[@frebify]

I have both and even paid about $400 for each. Got the pink h8h and it had a set of pink aluminum beadlocks and a pink servo horn inside as a surprise. I would say the h8h is the better buy simply for being app controlled and foc

[@DoRC]

@@lyricofwise6894 Yeah it's a bit smaller than the Rlaarlo but definitely bigger than a normal 1/10 scale crawler

[@applefordguy76]

My Cross RC Emo rigs have that rear link system. Its called a Watts link.

[@DoRC]

Sort of. A Watts link is actually this but reversed and I'm not entirely confident that this will work as a watts link in This specific configuration. That's probably what they were going for but they kind of missed the mark a little bit. It also seems kind of odd that they would use a watts link with a four length since the four link is already plenty to keep the axle located

[@Nutz_forRCs]

FWIW, Mjx says the whole truck is IP67. Presumably this includes the electronics and drivetrain. Does that mean that the linkage and axles are sealed to prevent water ingress? Perhaps that’s why there is so much grease in all the gears? What do you think?

[@DoRC]

I highly doubt it. Usually when they talk about something being waterproof they're only talking about electronics.

[@Nutz_forRCs]

Do you happen to recall if the hexes can be easily upgraded to take 14mm bead locks? Surprised they’re using 12mm hex on 2.2 wheels

[@DoRC]

@Nutz_forRCs I'm sorry I don't remember specifically though I don't think they were anything special. I'm reasonably confident that you can find some 14 mm hexes that will work.

I take it you've never seen the traction hobby cragsman pro? Built like a tank and proper 1/8 scale stuff and made to last, with no expense spared. You're welcome!

[@DoRC]

Definitely a cool looking truck though I think part of versatility is being affordable and the cragsman looks amazing but at nearly double the price probably isn't quite in the same category.

[@praetor47]

honestly, the only thing truly holding this thing back (other than the obvious parts availability :)), is that very top heavy body messing a lot with the CoG hopefully the next version (if it comes) will be something a bit "smarter" (like a pickup), and i'm jumping on one as soon as i find a store willing to ship to my neck of the woods

[@DoRC]

I think that would be really a disadvantage only when compared to serious rock crawlers. Pretty much all of these trail rigs have heavy scale bodies on them so it's more of a inherent part of the trail truck subtype then a problem in my eyes.

[@praetor47]

@@DoRC well, yes and no :) i don't mind the heavy scale body at all (quite the contrary), i only mind the choice of the defender with full cage, which is exceedingly top heavy. you can even see in your bashing segments how much of a detriment it is to the performance, making it topple over nearly every time you're cornering

[@IsaacSchultz-lz8jc]

It is honestly great to see more companies using brushless even if it ads a little more cost to the car it always seems worth it to me

[@DoRC]

I agree. Crawlers typically have used brushed motors just because they tend to be smoother at startup than even sensored motors but this FOC control completely changes the game.

[@Nutz_forRCs]

@@IsaacSchultz-lz8jc agreed. Excited to see how the rlaarlo mk07 runs with the sensored brushless setup.

[@IsaacSchultz-lz8jc]

It will probably be affordable to and that should you don’t need to charge copious amounts for a brushless system

[@Nutz_forRCs]

Theoretically shouldn’t an 80amp esc should be able to handle 4s if you’re not gunning it all the time? I know the 10bl120 is a safer bet, but with a 1500kv motor do you think you could get away with it?

[@DoRC]

Yeah and 80 amp ESC would probably be fine. The reason I put the 120 in was because the stock ESC is not 4s compatible and the 120 is what I had.

[@Nutz_forRCs]

@@DoRC well that’s what I meant. When the company says the 80amp esc is not 4s capable, is that because it really can’t handle 4s? Or because they don’t want people to go bashing full throttle on 4s, blow the esc, and then make a warranty claim? Curious on your thoughts

[@DoRC]

@@Nutz_forRCs oh. I'm not certain but usually if the ESC isn't compatible with a specific voltage it means that it will either fail to start when you apply that voltage or possibly blow up. This ESC might be able to handle 4S but in my experience most of the time they won't

[@EinfachSimon0815]

Would a hobbywing max 10 g2 work with the sensoren wire?

Another nice review! And a crawler! Backflips included! 😂 (almost) Poor thing! 😅 Looks like a tough rig, full of features! That gearbox seems similar to the Yikong/Absima/Rebelcon. I have the 1/10th version, but they offer a 1/8th too, rebranding maybe? The axles have some hard edges that will surely catch on the rocks. Can't say I like the body, I'm super tired of Defenders and that colour... 🤢 Hope there are others. Transparent light lenses are not for me either. But these are personal preferences. Eletronics seem solid and above average for an RTR! 👏 Did you spot a free channel for a winch?

[@DoRC]

Yes it has a winch channel on the receiver.

[@just.jose.youtube]

@@DoRC another nice feature! Cool!

[@magnusstone]

Is FOC the same as sensored?

[@DoRC]

Not really. The sensored system uses physical sensors to detect the position of the rotor as opposed to using what's known as back EMF to kind of guess where the rotor is. The FOC system is a more advanced way of calculating when to fire the windings in the motor to make the motor work as efficiently as possible throughout its RPM range. FOC doesn't even require a sensored system.

[@magnusstone]

@@DoRC interesting! Any recommendations for FOC systems for bashers? Maybe a smaller one like LC racing?

@@magnusstone I'm not familiar with that many systems. I know the hobby wing axe crawler combos are FOC but I'm not sure how much benefit you would get on a basher.

[@boduke9428]

I really like the features this has. The light options are cool but the 2wd/4wd option is my favorite thing and what i most often wish my trx6 and SCX6 had. I'm not into crawling much and rarely drive the ones i have. This and the Rlaarlo one have definitely had me thinking about selling or trading mine and getting those just to have something different around. The only thing kinda making me hold off is I'm pretty confident I'll be able to get parts and stuff for a TRX or SCX6 five or even ten years from now. I'm not as sure about this or the Rlaarlo.

[@DoRC]

Unfortunately this one does not have the two-wheel drive four-wheel drive option. It has high low and locking front and rear differentials but it's always four-wheel drive.

[@RcPlayer-tt2vw]

Is that why we use dog bones in the rear of RCs , they are stronger ?

[@DoRC]

No. Dog bones are used in the rear because they can get away with it and they're cheaper. Because you don't have the steering angles like you do in the front the dog bone style joint is effective. If you use it in the front the dog bone will tend to fall out. On a solid axle truck normally the rear axles are just solid chunks of steel again for cost savings and because you just don't need the swiveling capability of a universal. In this case they're using them just because it reduces the parts count and I guess they determined that way was cheaper than having two different parts for the front and rear.

[@RcPlayer-tt2vw]

@@DoRC thanks I always wondered why they weren’t used in the rear , cost is one thing but you think if it’s better we would do it as a upgrade or a company trying to one up the competition. I’ve seen guys do it with the typhon , probably be smoother , be cool have center driveshaft a cvd 😆

Seems alright but think being a brand we're all the cars been cheap in price seems like there last new one the 1/10 truck and this there jacking the price up maby a few hundred lower it be a good buy....

[@DoRC]

I think this would be difficult to make for that that much less. They definitely are going a bit more upmarket but this is a more up-market car. It is one of the few crawlers that comes with a brushless system and it is quite a bit larger than most of the competition. I think other than the potential for parts availability issues it's pretty competitively priced.

Basically it does not bother me that hobby shops don't carry parts for this brand as long as parts are available online. I may fetch one of these. I very much like scale looking vechiles but the biggest gripe has been they are usually slow. This is why I no longer have interest in my Trx4 which Traxxas desperately needs to update.

I think it just depends on what your goals are. In The second part of this video I was primarily trying to show how durable the truck is and what it's limits are. It's hard to do that without pushing the vehicle beyond what it's normally supposed to do. I would definitely not recommend anybody take this truck off of a ramp but taking it off of a ramp and slamming it on its lid shows what would happen if it fell and landed on its lid :-)

Tires look like cut canyon trails Looks like they copied the trx4 maybe scaled it up a hair You never really did any crawler things tho At lesst not on this video Tbh I’d stay with the big brands when you buy something like this you can get into the losi team associated type scenario Where they make their platform obsolete within a few years and you have a car you can’t buy parts for few years in I’ve had my axial since 16-17 and trx4 defender a month after release

Yeah a few other people have mentioned that. I've actually owned two TRX4s but they were both purchased used and didn't have the original tires when I got them So I've never seen the canyon trails in person.
