TESTING the TOP SPEED of “The CHEAPEST Traxxas Slash” RUNNING a HUGE 31t..It DIDN’T Go To PLAN!!! 😕

[@noneya7937]

There is lipo and neckle metal mode on the ESC read the manual tells you how it works.

[@gourobkundu2173]

Bro, the current drawn will be off the charts. Look when you cycle in a really high gear, you cannot accelerate fast enough. Even after reaching a point cannot increase your speed. This is exactly what happens with the slash. After a point, the motor paired with the super high gear cannot provide the necessary torque to propel it to higher speeds. Also there may be a overstrain protection in the b esc. Go brushless. BTW loving your content, From India. Also , forgot to mention, those connector adapters are just a makeshift thing. They increase the overall resistance and cause lower top speeds and that limping at full throttle.

[@RCKnockout]

Thank you! You’re definitely right about that Bro! Lol 😂

[@NathanStorer-RC]

I'd say it's a safety mode. With the bigger gear on, it's going to try to draw more current from the battery. Traxxas' batteries generally only have a 30c discharge rate, and you have a 60c discharge rate, so your potential current is higher. You probably need to either find lighter tires, or go to a brushless setup and a slightly smaller gear.

[@RCKnockout]

You are absolutely correct! It was going into some sort of limp mode probably caused by the current draw that the esc was demanding

[@RCKnockout]

@Jacques Lee yeah I’ve been told to take it out of lipo mode. I’m not running this system anymore though so I think I’m good thanks 😊

[@RCKnockout]

@Jacques Lee that is true it might stay on the ground a bit better. I would be a bit worried about frying my esc or motor though lol 😂

[@mattfoster1684]

All traxxas ESCs have that Lipo Safe thing. Read the instructions to turn that feature off. When LSM is off the light on the ESC is solid red, not green. The threshold is quite low for that low voltage protection, especially with 2S. I run mine without that protection and just pay close attention to power loss so I don't kill my batteries.

[@RCKnockout]

Yeah I know how to change it. You think I should try running it without lipo cutoff on? But still using the lipo battery?

[@mattfoster1684]

@@RCKnockout Yup. That's how I run mine. Before I did the VXL upgrade and ran 2S I had the same problem with early cutoffs.

[@mattfoster1684]

With that gearing your launch is pulling a big load that immediately drops the potential voltage below the threshold. You're getting faster top speed than my brushless one with stock gearing, but I think you're torturing that little Titan motor. Possibly that's the intention?

[@RCKnockout]

@@mattfoster1684 so basically you just have to be more cautious about what your battery voltage level is. Not to let it go to low

[@RCKnockout]

@@mattfoster1684 I don’t mind torturing it lol. Wait..so your VXL-3S doesn’t go over 33mph with stock gearing?

[@jaredharris1970]

Could it be a bad esc ? Try resetting it and reprogram the mode

[@RCKnockout]

I don’t run this esc anymore

[@cbossplayz3555]

it could be trying to put out enough and it is just over volting the esc or it could just have too much torq in the gears and just so you know brushed systems can not take that much torq i would try brushless because it can take more torq in it i would try a castle sw4 they can take that much torq

[@fuzion1094]

More load means lower voltage at the battery terminal due to internal resistance of the battery/wires/connectors. It would not 'overvolt' the esc. If anything esc can overheat due to over current, but he said the esc is cool to the touch.

[@cbossplayz3555]

It also could have too much torq

[@cbossplayz3555]

Brushed can’t take that much torq as I said

[@fuzion1094]

@@cbossplayz3555 brushed systems have "less" torque. If it's over geared it won't go faster because the motor doesn't have enough torque. But it would not cause the esc to go into limp mode and blink. It could overheat and go into thermal shutdown, but the esc is cool.

[@cbossplayz3555]

As I said it is too much torque is making the brushed stressed out and that is why the gearing is too much torque for the brushed

If you had to cut down if the transmission in order to fit the pinion, that means the spur is too big. Big pinion + small spur = fast.

Yes it’s over geared quite a bit higher than Traxxas recommends

[@bryanglover3775]

As a rule of thumb it's 1 to 4 pinion to spur gear to split if you give him a 23 and say a 54 is about the same gear ratio and it won't eat the battery up as fast

[@SebastianLong]

My guess would be the adapter isn't allowing the necessary current through and the ESC thinks the battery is at low voltage. Also I must ask, why didn't you try a 3s?

[@RCKnockout]

It’s not a 3S capable esc. It says it can only go 2s

[@rc123channel7]

It will blow up the ESC

[@cuongandmari]

You should go down on spur and up teeth on pinion gear = faster. Instead, you up teeth on both spur and pinion gears therefore it defeated the purpose?

[@RCKnockout]

I just looked at the video myself. Cause what you said made no sense. I said in the video that I was running a 31t pinion and 86t spur gear. That means I went down on teeth with my spur gear. Stock was a 90t. Not sure where you got that from?

No problem; I’m honestly just curious what it’d do; and $20 isn’t bad. If I woulda known about it before I bought my vxl I would have tried it and bought a second motor and just swapped out motors when they blow and keep them in rotation warrantying them. 😂 I should try a 31 pinion with my VXL.
