Brushless Worker Hurricane Cage + Flywheels

thingiverse

Stock motors in a Worker Hurricane are subpar. However, they can now be upgraded to a Brushless setup. Performance on 3s averages 142fps with highs reaching 167.9fps. **Version 2:** An update to version 2 was released on May 5, 2019. Both the upper and lower cage have undergone changes, and are not compatible with v1: - Integrated barrel. - Reduced (eliminated) barrel jams. - Enhanced performance. - Easier installation. You will need to remove 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 that 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. If you get it wrong, you will soft-brick your Arduino. If you're unsure what this means, get the Nano instead. You may struggle to fit a nano in. **Printing Info:** Flywheels must 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 are needed. 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 assume that you have a 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 else is set to default. **Wiring:** Firmware has been uploaded. - Rev trigger connects to Pin 4. The side of the switch connects to Ground. - 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. **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.
