- Part 1 of Project Wheeled RC Tank. Putting together the electronics for a first test and run into a problem with the radio receiver and motor drivers.
Check out the motor driver running in #shorts:

You claim to have fabrication skills and learning machining? For me it all integrates into the project, as you will find I am sure. The more skill at machining and fabrication, opens up more design options.
Watch the guy at Fireball Tool for some ideas - quite a talented guy.
I'm definitely subbed to Fireball Tool...that guy has one amazing shop!
Ditch the DeWalt batteries and use standard lithium 4S, 5S or whatever the motors & controllers require. Yes, get RC ESC's as well - that have reverse capability. Also, junk the steering wheel radio and get something like a helicopter dual stick radio. A helicopter radio will give you mixing options for the different channels and the ergonomics will be much better.
Sounds like a lot of money to spend :)
The Dewalt batteries could get changed out at any point but I have a pile of them on hand and are effectively 5S batteries anyway right?
The steering wheel radio has mix control built in, for under $100 it was the most economical option that didn't need external programming via sketchy software.
You're right though, if version 1 of this RC works, version 2 might need some upgrades.
@@SomeGuysGarage Sorry dude, easy to spend someone else's money. The motors look healthy. Are they brushless?
The batteries will work fine, easy to swap them when depleted.
Never mind, I looked at the video again and see they are brush motors.
Should be a fun project!
@@zangzang1268 no worries, it really is :)
Yup, just 250 watt brushless pancake motors...the price was right.
Do you have to use a motor controller for those amp flow motors? Or could you simply just connect DC voltage to them, and they will spin? I have one here, and I am applying 18 V to it… But it won’t spin.
They should not require a motor controller, a straight DC source will work. Make sure it can deliver enough amperage though, they have a fair bit of current draw at startup and could exceed most typical bench power supplies...but a tool battery like I used should just work straight away. Oh, and make sure the motor is held down, the mass of the rotating assembly will cause them to jump if just sitting loose.
@@SomeGuysGarage thanks! The resistance of the motor appears to be about 1.7 ohm. Hope that’s normal.
@@vantongerent I'll double check mine later today. Are you using a battery or bench supply?
Also, be careful if you open up the motor...I did it once to re-seat a brush and it was very difficult to get back together (used some MIG wire to hold the spring loaded brushes in while putting it back together and then just before closing it pulled the wires).
@@SomeGuysGarage I'm actually trying to power it directly from an 18V-100W solar panel. I saw some youtube videos showing this was possible... but now I'm not sure. Thanks for checking!
@@vantongerent check with a battery (even a pair of 9v's should do to just get it to turn) or something else to make sure the motor is good. If you're using the same motors as myself, I doubt they'd turn with a 100w panel unless it was in direct sunlight and even then could be a stretch.
