I have a pair of 13T gearboxes(no motors) for sale. $25 shipped. These were in a lightly used hurricane with high speed lock out never removed. Please email me at cas0586@yahoo.com. I will also try to check in here. Thanks.

I ended up using this setup in hurricane. Have not been around, sorry for the delay.

<t>Just trying to get by with the parts I have on hand. Not looking to buy more relays and what not. I have plenty of shifter switches... and what about the braking setup?

<r>I have done a few ESC setups with the two relay brake/reverse setup. Any reason we cannot use the factory shifter to control forward and reverse function while utilizing one SPDT relay for braking? Would this damage the ESC into the typical full throttle runaway with braking resistor? Here is my ...

sall

No doubt! Always an accomplishment building yourself! Easiest 18v solution with typical esc is to simply use a pot on the throttle wire.

sall

So, our three year now drives himself in this jeep with RC controller. Albeit with the throttle trimmed it is still funny.

sall

Very cool. I probably parts in my bin to make one. However, by the time I transfer and etch that PCB $12 for a 24V 500W controller sounds more appealing. Don't get me wrong I am a DIYer but... I have to concede sometimes.

sall

<t>You are definitely going to want to use an aux battery for the LAC and actuator. Battery voltage drops and the LAC becomes slugglish and unresponsive otherwise. Connection to the LAC are very simple. Power and ground from battery. Signal and ground from receiver(no 5v power from receiv...

Shifter Diagram.

A good byproduct of this setup is that when going from forward to reverse the motors will always be braked. Even if only for a split second.

<t>Will throw up a diagram of the FWD, Park/Neutral, RVS shifter configuration when I get a chance. I am wondering if 10 gauge OFC main wiring is enough for this setup. I do have some larger wire but connecting to the battery is the issue. Likely directly soldering to battery tabs.<...

<r>Here is how I did the 'floating' pedal. I don't know what to call it? Only showing one ESC but simply parallel the three pedal wires. I used the diode to prevent backfeed to the pedal.

What is a good 500 series with quite a bit more torque than standard PW motor?

sall

Will post my results with dual esc upon completion and a few hours of use. It is no surprise though. There is small differences in overall ESC from one to another simply due to part tolerances.

sall

<t>The brakes on the common ESC setup short the motors out to brake. Braking can be softened with resistors. The brake must manually be pressed. If you let off the accelerator all that happens is the vehicle rolls to stop. One could set the brake relay up so it's always active when the th...

sall

I will just drill hole in each ESC enclosure and mount a pot. Dial each motor accordingly and see what works... or doesn't work.

sall

As for the 'coast' setting without being on throttle does something around 4v to the motors sound right? On a 12v build low is in a perfect situation 6v to each motor. That is supposedly 2mph. So, a good voltage to the motors for a slow crawl about 4v?

sall

Yeah you can use a pot on the throttle connections for many different purposes. I will do some testing when I get the chance. I still need to do some modifications to each controller and get rid of some clutter from them.

sall

That was a concern I had when you said you were using dual controllers in your build crusher if you remember. The controllers seem to very well in tune with each other when I tested some things on the bench.

sall

<r>Just to verify with toycrusher, connecting the ESC throttle wires in parallels works with no ill effects? Build is progressing... <IMG src="http://i.imgur.com/prQxXKcl.jpg"><s>[img]</s><URL url="http://i.imgur.com/prQxXKcl.jpg">http://i.imgur.com/prQxXKcl.jpg</URL><e>[/img]<...

Has anyone actually tried using the YK31C brake controls? The early failures were with the LBD14, correct? Do they have the same internals?

sall

<t>Right. According to my DMM at 1.1V at the throttle return I start to get motor activity. So, I used the 5k pot to simulate that. I'll just have to see what voltage at the throttle return is the sweet spot for just rolling once the wheels are on the ground and his weight is in the rideon. Then set...

sall

<t>Well, what I mean is if the ride on is keyed on and either the shifter is not in N/P or the brake is not pressed the ride on will creep along. Fast enough where the brake pedal must be used or shifter in park/neutral for the ride on to be at complete stop. Slow enough to not cause any accidents i...

<r><QUOTE author="toycrusher"><s>[quote="toycrusher"]</s>Sorry I missed it till now. Diagram looks perfect. Since the motors are independent, 30 amp relays should be more than enough.

<r>ToyCrusher, I have the voltage comparator setup working on the bench. So it is not a hassle to add that feature. Just will take an extra DPDT relay per controller setup.

sall

I have two 24V 500W YK31C ESCs and a pair of #7 21T gearboxes with BaneBots mounted to drop into this jeep for another upgrade. Will one '500W' ESC per BaneBot be sufficient or shall I still consider an ESC bypass?

sall

The consensus is paralleling two ESC outputs equals fried ESCs. You can try it though if you want. It's a $30 gamble that the house likely wins. Relays are cheaper!

sall

<r>I don't know 100% that it won't work. If you read about how the controllers function in the mod thread I posted... <QUOTE><s>[quote]</s>"Basically YK31C is PWM controller for brushed DC motor with low voltage protection and current feedback limit.Core is triangular generator, which is comb i...

sall

I don't think combining the two ESC outs together would be a very good idea. I'd stick with separate relays for the each ESC and motor.

sall

Thanks, skinny. Looks like used a 5k pot. I knew it was possible was just unsure of the value. I'm just using it for bench testing some mods. See how it goes once I get my experimental YK31C.

sall

Thanks. They had them at Lowes in the specialty drawers. Got them mounted on the 21T gearboxes last night.

Try just connecting the rc signal to the rc screw down terminal below the power/ground terminals.

<t>So, a few weeks into a working setup here. I notice when under heavy loads or batteries getting slightly low the actuator becomes sluggish or some times unresponsive. I am assuming the motor draw is causing the LAC to be under powered. Does this sound about right? Only conclusion I can think of. ...

sall

Should be able to simulate the pedal with voltage drop across the pot? Just want something for bench testing. Suppose I can buy a cheap $2 twist throttle.
