Mamba Max Settings ?

[Jason]

Hi, which setting in the mamba max 1/10 esc can affect top speed ? and by how much ?

Top speed is mostly determined by your motor, and battery. The esc is for fine tuning punch conttrol, lvc, brakes, etc. Mostly, the esc settings are designed to help keep all 3 components working together.

If you max out the settings on the esc for say punch control and start power for ex. you will go faster per say, but, your motor, esc, batts will not last.

If you want to go faster, buy a better, bigger motor and a bigger battery that the esc will be able to handle and gear accordingly.

Punch control has no effect on top speed, just acceleration via throttle response. The higher it is set, the more it will limit throttle response. However, it will not limit top speed, as it eventually lets the ESC go all out. I like the raw feel of power, so I never set any punch control, I leave it off. I like to modulate the throttle myself.

Start power has also no effect on top speed, it is just a setting to top with to affect the initial acceleration from a dead stop. It is mostly used to tweak the start to help minimize cogging. Some motors like higher start power to get off the line smoothly, some don't. Both of my motors are 2-pole Lehners (1930 and 1940) and have always worked very well on low, so I haven't bothered changing it. The lower the start power the better, however, as cogging is basically shorting, and would you rather have your ESC short when its sending more or less power? (Less, obviously.)

Thre is the one setting I know of that actually affects top speed, but not by much. From my experience it is quite a minute change from setting to setting and going from very low to very high still does not have much of an effect. The setting is the timing advance. The more it is advanced (higher the setting), the higher the top speed. However, there will be more heat generated and more current pulled. Its really quite similar to changing the gearing for more top speed. Lowering timing will have an opposite effect (cooler running motor, slightly less top speed and current). Similar to gearing for less speed.

Now, as I said, these settings are quite fine, and in all reality don't have so much of an effect. In my experience top speed is relatively unaffected, and if anything all that happens is more current draw and more heat, so I always set it on normal (on the low settings, I feel that acceleration is slightly adversely affected). If anything, this setting should feel as the super fine setting in gearing. The Standard setting is the pinion, the fine is the spur, while adjusting this is the super fine.

I wouldn't use it to get more top speed, instead I would do one (or more) of the things below:

Change gearing for more speed (assuming the ESC, Battery, and Motor can handle the increased strain)
Get a bigger motor with higher gearing, or a higher RPM motor (assuming ESC and battery can handle increased strain)
Increase the voltage (assuming ESC and motor can handle it, usually the gearing has to be slightly reduced to help cope with heat, but speed is generally always higher even with the lower gearing)
Better Batteries (hold more voltage under load and therefore provide more top speed)
More efficient motor (less power loss, more power spent on gaining speed than generating heat)

Obviously, if you bought a bigger motor, a more powerful ESC, and a high voltage, high current battery all at once, your limit of power would be mostly held back by the amount of money you wish to spend (and your drivetrain). I maxed my drivetrain out, so I'm glad I didn't spend much more than I did...

The 'on/off' setting greatly effects topspeed, and by a large amount...

Hey thanks BP-Revo for the Professional Explanation!

Lmao...

No problem Jason.
