Mamba x vs axe

[King Dork]

Assuming the same kv, startup is definitely smoother with the standard, less "spongey" feeling.

I totally agree with this. I have a Copperhead/Puller Pro 2200 in a TRX4, and a Mamba X/Puller Pro 2200 Stubby in my Capra. I realize apples to oranges as far as vehicles, but the escs have virtually identical settings and the combo in my TRX4 is definitely smoother low speed. The Stubby is still fairly smooth and more powerful than I expected. The standard has ridiculous power!

Mambax much more programming options, hobbywing is easier to program (computer program vs Bluetooth app)

Mamba has a stronger BEC

Mamba with a HH Puller pro will be an almost unoticable amount smoother, but gives more punch. The extra punch isn't really needed when crawling but it does have more punch.

Axe is a good amount cheaper.

For most crawling, the axe is plenty, you'll never use more than 4s on a crawler and even 4s is kind of overkill. You can program the Axe on the fly with an app, Mamba requires a castle link cable to connect to your PC.

You won't notice much of a difference trailing around and crawling, maybe on technical sections you can really fine tune a mamba to your liking, but most people wouldn't notice.

There is a Bluetooth tuner for Castle.

You want 4s so you can gear down even lower and still have wheel speed, this makes a big difference in low speed control and torque. If you have a direct power servo that can handle 4s it makes a difference.

For slow speed control and steering you will notice a difference on 4s.

I have had both the Copperhead and MambaX in the same rig set up exactly the same and for low speed there is no difference, for high speed there was no difference. The only difference for me is the Copperhead would stall after about 10 minutes. If things are different between the tow rigs it has to do with gearing or maybe something binding.

No doubt it’s probably the rigs. The Capra has absolutely horrible slop in the drivetrain. Next time I feel like wrenching on it I’ll probably see if the ring and pinion gears SSD shimmed. I’m disgusted at the amount of slop where the axles key into the diffs though. Not a lot of time on the rig and I’m fairly gentle on it. I beat the crap out of my TRX4 and have had it quite a bit longer and it’s drivetrain is far tighter than the Capra.

Interestingly enough, I was listening the sbg vs hd live takeover ep10 with John Holmes, and at around the 1:02:00 mark John claims the stubby pp has smoother start up than the standard.

What may be working against you in your example, is the overall higher ratio of the Capra combined with less torque of the stubby motor giving the feel of less smooth startup.

Just a thought.

I have gone from full size to snub nose Revolvers and those snubs do have smoother start up. Less mass to get moving???? But snub Revolvers have less drag brake. In theory I suppose the snubs maybe would have less torque but if they do I can't tell. I would think the puller pros would be the same.

That's not been my experience at all, although I could see it being true with no load on it. The stubby has a "spongey" feeling to me, where I have to squeeze the throttle further to get it moving in a sticky situation (not full on bound up) and then when it finally does go, it sorts slingshots ahead. Switching to the standard size in the same car mostly eliminated that spongey feeling. The standard size revolver in the same car never had that spongey feeling, but (besides the noise) it just wasn't as smooth at the lower end of the rpm range. More torque certainly helps.

It could definitely be a scenario where unloaded the stubby will start at a slower speed, but during actual use, the standard has a better feel

My Capra with 10.2 axles and transmission and a stubby pp, doesn’t feel much different compared to my heavier vs410 pro with a standard pp, as far as low end control is concerned. But I could see swapping motors on either rig may yield the same feeling you both are describing

I had to gear down on my heavier TRX axle trans setup (about 7.5 lbs) when I went to the snub and then it was smooth as glass. I now run it on 4s and it is smooth at low speeds and good wheel speed. I am using a MambaX.

My other two comp RCs ae under 6lbs. I only noticed an improvement with them. I run 3s with SW4s.

I have driven Puller Pros before but they weren't mine and it was just playing around so I really don't know ow they compare to a Revolver.

Alright yall talked me into it. As much as I was leaning towards axe. I'm going for the mamba x and hh puller pro. I'm gonna do the 2700kv I think. What's the difference on standard vs stubby? Obviously length. But will the stubby have less or more low speed startup?

I don’t think you’ll be disappointed. CC and HH are an awesome combo imo.

hello i'm thinking changing axe550 3300kv (current) to mamba x + hh puller pro 3300kv or 3800 will i feel the difference after changing esc or just same to same ? ps i'm new to rc world and also new to crawl cars

heard mamba has lots of settings to go but loud compared to axe but mamba has more power in bec and in dragbrake too i wish to compare in real world but just have trx6 hw axe system

will the changing worth or just recommend not changing as both are highend specs so just same to same for rc crawler newbie?

thanks for watching my comment
