Du-Bro 101 – How To Balance Propellers on RC airplanes

--Video Below--

Balancing your model airplane propellers will give you better performance and help your equipment last longer. Don't worry if you've never done it before. We have a few tips to help you balance nylon and wood 2-blade props using our Tru-Spin Balancer.

Nylon Props:

  1. Clean any flash that may be on the blades and hub with 200-grit sandpaper.
  2. Prepare the prop for mounting on your model (ream the hub or install spacers as required).
  3. Set both side plates of the balancer to the same height.
  4. Mount the prop on the balancer shaft.
  5. Set the balancer shaft on the side plates.
  6. Hold the prop horizontal and gently release.
  7. The heavy blade will rotate downward. Mark the back side of the heavy blade with a marker.
  8. Add small pieces of tape to the back side of the light blade until the prop remains horizontal when released.

Wood Props:
  1. Prepare the prop for mounting on your model (ream the hub or install spacers as required).
  2. Set both side plates of the balancer to the same height.
  3. Mount the prop on the balancer shaft.
  4. Set the balancer shaft on the side plates.
  5. Hold the prop horizontal and gently release.
  6. The heavy blade will rotate downward. Mark the back side of the heavy blade with a marker.
  7. Carefully remove material from the back side of the heavy blade using 200-grit sandpaper.
  8. Remove small amounts of material at a time and re-check the balance often.
  9. The propeller is balanced when it remains horizontal when released.
