RC Remote Calibration and Rebinding

This video shows you how to adjust the Calibration Knobs on the Metroboard RC remote in the event that either your board is beeping even though you aren’t turning the wheel on the remote and also if the drive wheel is spinning even though the trigger on the remote is in the neutral position.  This adjustment may be necessary if the knobs get bumped out of position or sometimes due to temperature variation.

In the second half of the video you will also see how to rebind a new remote to the Metroboard and also how to set the fail-safe (how the board behaves when it loses connection with the remote or if the remote batteries are low).



Timing Belt Tensioning

Once a month, or any time you hear a clicking sound under hard braking, you should check and adjust the tension in the timing belt following the instructions shown in this video:

These smart phone apps work well for adjusting the belt tension:

Note that the belt tension (which will change a bit as you rotate the drive wheel) should be adjusted such that it is between 200 Hz Minimum to 260 Hz Maximum, when using the above apps and "plucking the belt".


Abec11 Flywheel Pulley Insert Removal and Reinstallation

This tutorial will show you how to remove and reinstall the Aluminum Pulley Insert into an Abec11 Drive Wheel on the Metroboard Electric Skateboard. This is useful if you are installing for the first time or if you want to rotate the Pulley Insert to a non-drive wheel to even out the wear.  Also if your drive wheel is making any creaking or clicking sounds, the video will show you how to eliminate the noise.


Truck Bushing Replacement

This tutorial shows how to replace the inner truck bushings from Cylindrical to Conical to improve carving and maneuverability on your Metroboard Electric Skateboard.  This is especially helpful for lighter riders that find the standard bushing setup a bit hard to turn or for anyone that wants a more fun carving experience and tighter turning radius.  You can order the Conical Truck Bushings here.


Wireless Remote Troubleshooting

If you are having issues with your Metroboard IR Wireless Remote, such as:

  • poor wireless performance
  • 8 monotone beeps followed by the brakes being applied

Then please check the following:

    • Round AAA battery holder has popped loose inside the remote resulting in poor electrical contact.  Try removing and reinserting before every ride to ensure good electrical contact (since sometimes it gets bumped loose if it’s in your pocket or backpack).  Also, be careful not to bump the remote against your body as you are riding. 

 

    • Remote batteries need to be replaced (use only Alkaline or rechargeable NiMH). Note that often the colored RED and BLUE lights will still work, but the Infrared wireless LEDs WILL NOT WORK, because they consume more power than the batteries can deliver when low. So don't assume that because the colored lights are working that the batteries are still good.  Note that if you are using NiMH rechargeable AAA batteries, then you need a charger that can charge individual batteries (not in pairs, e.g., 2 or 4 batteries like some cheaper chargers out there) which is necessary since the Metroboard remote uses 3 AAA batteries.  This NiMH Charger will work well and comes with 9 AAA NiMH batteries so you will have some spare sets you can take with you in case your batteries die in the middle of a ride.  Do not use “super heavy duty” type batteries as they can’t handle the power demands of this remote.   Note that the 3 white arrow stickers on the side of the remote are to help you orient the entire round battery holder inside the remote (the arrow should point towards the joystick).  They are not to be used to orient the individual AAA batteries.  The individual AAA batteries should be oriented such that the negative side of the battery faces the coil spring inside the slot of the round battery holder (as is the standard orientation).

 

    • Try bending the leaf spring battery contact in the remote that is close to the joystick. Gently pull it out so that it interferes more with the battery holder as you insert it.  This should apply more force on the round battery holder which should result in better electrical contact.

 

    • Clean the battery contacts on the remote with rubbing alcohol on each end (the cylindrical contact on the back of the remote and the spring contact near the joystick).  Also clean the contacts on both ends of the round AAA battery holder as well . Use a clean lint free cloth with rubbing alcohol.

 

    • Clean the individual contacts inside the round battery holder for each AAA slot (both the coil spring as well as the tab).  Also do the same for each end of the AAA battery itself (since if you are using rechargeable they may be contaminated with finger grease over time).  Use a clean lint free cloth with rubbing alcohol.

 

    • Check to see if the Infrared (IR) LEDs are working on the remote.  You can't see them with naked eye, but if you take a video of them (with a smartphone or digital camera), you can see them emitting a pulsing purple light (see video below).  Note there are 3 Infrared LEDs (1 in the center and 2 hidden on each side as shown in the video). Do you see the purple flashing light? Note that you should do this in a room with not too much light in it, since in bright light it may be hard to see the IR LEDs. 

 

    • Check that the rear right screw of remote is tight as shown here.
