R/C Off-road trail trucks pose a unique challenge for brushed motors. Low speed binds are frequent. To make things worse, not every truck uses the same direction of motor! Knowing your brushed motor rotation and timing is critical for proper operation.
Please note that advanced timing will make forwards faster and more efficient than reverse. If you use reverse a lot, 6 degrees advance is ideal for overall performance and longevity.

I built my first rc10 in 1990. I liked how everything was back then. Soldering lightbulbs together to drain cells. I had a shoe box full of cells that I'd match together and solder a pack up. Cleaning brushed motors, using commutator cleaning bars, timing, armature lathes. Today everything is RTR and ready to go. Back in they day people seemed more knowledgeable because you HAD to learn/do that stuff. A lot of young people today don't really seem to know/understand much (there ones that do, don't get me wrong). And it's because half of them have never even assembled a kit. They just put a battery in and turned it on.

I love how smooth, quiet, and dependable HH equipment is. Oh Im running the 12v servo too!!!. Wow that bad boy is no joke. Gotta love not needing BEC!!!!!

I literally just fixed the timing on the motor and I got this notification I have been into Rc for 35 years and have never done anything with timing this video taught me a lot after I fixed the timing the motor worked flawlessly but I learned from your video that it was spinning the wrong way and so I did a 180 with the timing and now it spins correctly that just absolutely blows my mind you could do that again thank you again in case you’re interested it’s a team kinwald the dirtinator

Hello, 1st, thank you so very much for the educational videos. You make learning your products fun and entertaining. Also, learning the technical aspects of your products is invaluable and so very useful. I’m new to crawling. My question: Prefacing my question. I am an engineer from the aerospace industry, I work for an airline. All components on commercial aircraft are tested and retested for certification purposes. Regarding new aircraft, you can find many RU-vid videos such as the testing of the A380 wheel and brake assembly. Specifically, you will see the wheel and brake spin up testing the brake assembly to failure. Do you have the equipment to test shaft HP on one of your brushed and similar brushless motors. I would like to see a video of you spinning up the motor measuring Current Draw, Voltage Drop, Shaft torque, watts, and perhaps spinning the motor to ultimate failure. Thank you in advance! Rob-

I went on your site to order two motors and when it got to the part where it asked me do I need reverse rotation I got confused all over again.

Hey John! Thanks for these videos. They're very informative and in my case, somewhat of a refresher... I ran semi pro in the 80's to mid 90's.I have a question... Back in the day, we used to put "socks" over our Endbells, secured around the can with a rubber band or a zip tie. Kept larger debris out of our Motors. This is a bit of a question from the last video I watched about running in water.... I was wondering, would that old trick help our Rigs today, especially when going through water?? The way I see it, it won't keep everything out, but it should keep out the bigger chunks, that can jam up Brushes and Bearings...What do you think?Carmine 🚂
@HolmesHobbies
@HolmesHobbies 6 лет назад
That would certainly help. I prefer to just run sealed can motors though. I don't like getting water into expensive ones.

Great video! This will be a life saver for moa guys 👍 I'm building a dual 2200 kV Axial dragster and I've been researching... It looks like two ESC /two motors is the most reliable setup. I've seen a theory where they would use one ESC with two sensor motors. The first motor was connected with the sensor wire and the second motor operated sensorless .. stating that the first motor would give the ESC feedback to give both Motors the proper power.. my Layman's Theory is that I know my RPMs won't be any higher but using two Motors will help share the workload so I can use higher gearing just giving me incredible wheel speeds for hydroplaning vertical pit wall climbing Tire ripping speed on 6s because I'm also a purveyor of power breaking parts😯 so my question is if I used to ESCs with two Motors can I bench run them and adjust the timing through Castle Creations link to try to help out with synchronicity with a rpm gauge? Thanks 👍

Im building a electric bike, and i have a question about the rotation of the motor. I've built my diy bike, but the motors spinning the wrong direction. How can I reverse the direction of the motor? I have it hooked up to a 2 pin rocker switch and a 22.2v 1400mah battery and it all works, but how would i have to change it if i wanted to make it go the opposite direction? Its going clockwise now, but i want it to go counter clockwise. If i swap the connectors on the motor ( like connect positive motor wire to negative battery wire and negative motor wire to positive battery wire ), would that work?

adjusting the turns gives you more torque to or is just for durability of the brushes
@HolmesHobbies

peak torque will be around 30t range for a 540. this also increases brush life compared to faster motors.

Hi friend. My Hackmoto V2 13T motor rotation direction label says counterclockwise. But my Vanquish VS4-10 Phoenix crawler transmission rotates in reverse when pulling forward in the transmitter. Is it ok to just reverse the motor wires without damaging the motor to make the transmission move forward when applying throttle in the transmitter? I also ordered your Torquemaster 540 35T motor.

@HolmesHobbies

Depends on the rpm that the motor is spinning. For a crawler that is normally close to zero RPM, 6 degrees of timing is a very good setting. Each little mark represents 12 degrees.
@salinbabu6992
@salinbabu6992 6 лет назад
Hi John, I recently purchases a 540 35T sensored motor. Out of Box the rotation was faster in forward direction and slower in reverse. The current draw from a 3.6V 1900mAh Ni-Cd in the factory setting was Forward-1.06A & Reverse-1.04A. So I tries to advance the timing slowly by 6 degrees and the current rose to Forward-1.08A & reverse-1.06A, at 12 degrees the forward was 1.2A & reverse- 1.18A. Finally at the third notch(marking) the current had risen drastically to 1.72A at forward direction and 1.68A for reverse(and speed reduced too a lot). Would this increase in current draw impact the life of the motor significantly?
@HolmesHobbies
@HolmesHobbies 6 лет назад
Yes, increases in current will affect motor life, more significantly past 12 degrees of timing. The lower the better for brushes.
@salinbabu6992
@salinbabu6992 6 лет назад
Thank you. So, currently I've kept it at 6 degrees. Should I go back to the factory setting for longer brush life?

why is the motor more noisey from one direction to another direction
@HolmesHobbies
@HolmesHobbies 7 лет назад
Ric Gruber good question! You are hearing brush noise, which is common on stand up brush rebuildable motors without brush dampers (our pro handwounds have dampers). The brush seats in one direction during break in, while in reverse the brush wants to sit a little different. The sharp brush edge catches the comm gap, and makes a little noise. flipping the brush or sanding the sharp edges can help.
