Brushless Worker Hurricane Cage + Flywheels

thingiverse

Stock motors in a Worker Hurricane are crap. But you can now upgrade them to a Brushless setup. Performance on 3s averages 142fps with highs to 167.9fps. ** Version 2: ** An update to version 2 was released on 5 May 2019. Both upper and lower cage have changed, and are not compartible with v1: - Integrated barrel. - Less (as in no more) barrel jams - Higher performance - Easier to install You will need to cut off the barrel nubs **Shopping List:** 2 x Turnigy Viking 1308 4100kv motors: One CW and one CCW https://hobbyking.com/en_us/multistar-viking-brushless-outrunner-drone-racing-motor-1308-4100kv-cw.html https://hobbyking.com/en_us/multistar-viking-brushless-outrunner-drone-racing-motor-1308-4100kv-ccw.html 2 x Brushless ESC of 20a or more. I prefer BLHeli and have the Turnigy BLHeli_s 30a units installed. 30a - https://hobbyking.com/en_us/blheli-s-30a.html 20a - https://hobbyking.com/en_us/blheli-s-20a.html 1 x BEC module https://www.aliexpress.com/item/Receiver-Power-Supply-5V-3A-Brushless-ESC-External-Type-BEC-UBEC-Support-2-6S/32882504953.html 1 x Arduino Nano or Pro Micro https://www.aliexpress.com/item/New-Pro-Micro-for-arduino-ATmega32U4-5V-16MHz-Module-with-2-row-pin-header-For-Leonardo/32768308647.html Please be aware with the Pro Micro, you must ensure you select the right CPU clock frequency and voltage in Arduino. The default is 3v3 / 8mhz instead of 5v / 16mhz. *You will soft-brick your Arduino if you get it wrong.* If you aren't sure what this means, get the Nano instead. Despite the advantages of the Pro Micro over the Nano, this is the real Achilles heel - a moment's inattention will give you a bad day. You will struggle to fit a nano in though. **Printing Info** Flywheels need to be printed at 30% infill, with a 3d infill pattern (e.g. cubic). 4 Walls, floor, and roof layers are required for structural integrity. No supports required. I use Polymax for flywheels as it's nearly indestructible. Cage needs to be printed at 100% infill.Supports are required. I use ESun PLA+ for my cages. Upper cage can be printed in any settings you like. I typically use a 25% infill **Installation Process** Screw the motors into the cage using the included hex bolts. I have videos on the details of this particular build, but I have assumed that you have a fairly basic level of knowledge on brushless setups. There are plenty of videos on brushless nerf builds - especially based on Ultrasonic2's Ultra Stryfe. The process is fundamentally the same. My ESC's are tuned in the following way: - Timing = Medium High - Startup Power = 100% Everything it more or less default. **Wiring** Firmware is now uploaded. - Rev trigger connects to Pin 4. The side of the switch connects to Ground. The stock arrangement with the slide switch can be used to break this signal to provide a safety - Speed Pot center pin connects to Pin A1. One side of the Speed Pot connects to 5v from the BEC, the other connects to Ground - ESC A connects to Pin 10 - ESC B connects to Pin 9 (You can connect both ESC's to the same pin, but it will be a challenge to fit a servo split adapter in the shell). The other side connects to Ground. Typically, in an ESC, the light colour wire is the signal, and the dark colour one is ground. **Video Info** Pt1 - Demo https://youtu.be/QGZdFIZZkgs **Shoutouts** Shoutout to Ultrasonic2 as I cut my teeth building a number of brushless setups based on his files. That experience allows me to develop this. **License** Absolutely no commercial use of these models, firmware, circuit diagrams, etc are allowed. My exception is when you pay a general purpose print lab / service (such as 3dHubs) to print models for your own personal use. If you have anything else in mind, please contact me.
