Connect to the trainer

3. Turn on the trainer. Select the checkbox next to Fliiiight Smart Trainer, then select Connect.
4. Select "Diagnostic Tools."
- Re-center: Adjust for the current wheel position. The magnets will close on the wheel rim, pull the resistance unit center relative to the wheel, then release. Use this command if you've experienced wheel-magnet contact.
- Open: The magnets will open all the way. Open the magnets to easily get the wheel in and out.
- Close: The magnets will go to the wheel rim and stay there until they receive another command. In the absence of a wheel, they will go to their minimum distance. Closing the magnets makes it simple to check the height of the magnets relative to the wheel rim.
- Send a few different commands to check the motor is working.
- Backing out of this menu will restore the trainer to its default mode (if the trainer has not received any other commands yet) or to the most recent command, until it receives another commands. When the wheel is still, the default is open magnets. When the wheel is moving, the default command is 36% resistance.
Here, you can see feedback on the quality of your sensor readings, and tips on how to improve them.
- Spoke count: This should match the number of spokes on your wheel.
- Spoke quality: How clear spokes appear to Fliiiight’s high-resolution speed detection.
- Spoke baseline: This will alert you if the optical sensor is obscured.
- Average spoke (iOS): This a a measure of how reliable the trainer's current wheel model is.
- ADC torque: Your force reading.
- Motor Position
Trainer sensor tips
- Your wheel must begin spinning at least 27 km/hr (16 mph) for the system to engage.
- Make sure you don't have more than one speed index installed, or more than one object on your spokes in the path of the optical sensor, confusing the trainer's wheel model.
- If your wheel has wide, flat spokes, your trainer may not be able to distinguish the spoke index. Fold a piece of tape over one spoke lengthwise to create a wider index.
- Note that disc wheels, aero jackets, and wheels with more than 64 spokes or fewer than 14 spokes are not compatible.
