Lubing the Brakes
Your aircraft’s brakes have been lubed at the factory. If the braking action is not to your liking,
add or remove O-ring Lube as required.
Note: The main wheel brakes on earlier versions are activated by a simple on/off control.
Later models with the black control box use a pulsing action.
Sufficient lubrication applied to the wheel drum and the brake “o” ring allows smooth, straight
stops. At 60+ flights, the prototype model’s tires show little wear.
 Remove the wheel by removing the axel set
screws using a 2.0mm hex wrench.
Important: Do not lose the Nylon washers.
 Apply a generous amount of Super O-Ring
lube BVM# BVM5779 to the wheel drum
surface.
NOTE: Some early models have inflatable tires
with small air fill nipples on the outside of the rim.
Inflate to 30-40 psi for good ground handling.
Wheel Bearing Maintenance
 Apply Super Lube BVM# 5784 into the wheel
bushings.
 Reinstall the axel, wheel, and brake.
