RC Controllers with RC Motors

[Dauntless]

Just wondering what you use for a throttle. HobbyKing has a comment for one motor where they say to use a Servo Tester. That can be as simple as this.

Is anyone who uses an RC controller (Castle Creations, etc.) able to run a regular bike throttle? If so how is that achieved?

Also, I just saw this statement at HobbyKing and wondered if someone here by that nom de plume recognized the statement. Or maybe much of the comments posted are shills. Hard to say.

I run a pair of them on my bicycle, with 16 6S5Ah LiPo packs. This fellow is running a single one at 12S. It still goes pretty www.link

Hillhater's servo tester mod is super simple, just remove the pot and solder a single jumper lead. Your ESC must have a built-in BEC though.

I made a circuit using a dual 555 timer chip which I use on my bikes. Circuit here

about 1/2 way down the page - also shows it lashed up on veroboard. My mate did a PCB of it which I used on my current ebike.

If you're going to go with a Cycle Analyst for data readout anyway, the CA-LRC is a great unit that combines the functionality of the CA, servo tester, and BEC all into one unit and allows for full control of power output, startup speed, and few other features at a very reasonable price. Grin Technologies builds and sells them out of British Columbia, and we now stock them as well for folks that are more local to the East Coast in the US.

The servo tester gives a speed-type (throttle position correlates to motor rpm) throttle control, while the CA-LRC gives a torque-based throttle control (throttle position correlates to motor power).



We use these units regularly with Castle HV160 ESC's with great success. Either a resistance or hall-effect throttle can be used with the LRC.

Some ESCs have a built-in BEC, some have to use an external BEC (called a Universal Battery Elimination Circuit, UBEC), its the small green thing with the bar-code.

Some RC planes have accessories that use 5V, and a BEC is a small Voltage Regulator that "eliminates" the need for a second 5V battery inside the RC plane, by stepping down the main pack voltage (22V?) to 5V. If you are adjusting RC plane accessories that are activated by a servo, in your garage, a servo tester takes in 5V and adjusts its output. Here's a friction drive set-up with the basic components:

Tommy,
Is that the "Cycle Analyst V3 preview and first beta release"? I can't find it at bikes.ca, but I see it at FFR. I definitely want one, but I should be prepared to flash the firmware if new features are added yes?

MattyCiii,

We're currently stocking the Version 2.24 Beta4 units. They're the latest V2 units. We'll begin stocking the V3 units for folks when they've been debugged, we'll likely get a few early units soon for folks that want to be part of the beta testing process.

The V3 units will have major hardware changes, and a V2 cannot be converted to a V3 with a firmware reflash, however both V2's and V3's can each be reflashed with new firmware as it becomes available. We can reflash them for you, or you can do it yourself with the Pickit programmer.

Great thanks Tommy!
Crystal clear now.
