Du-Bro 101 – How To Install Spinners/Nose Cones on RC airplane

Using a Du-Bro spinner is not hard but you want to make sure you are selecting the right size for your model and cut it right to fit your propeller. Here's our suggested method:

  1. Select the color of spinner needed for your model.
  2. You can paint Du-Bro spinners by scuffing the surface and using a primer to help promoting paint adhesion. Electric starters will rub this off over time.
  3. Select the size of your spinner roughly 1/5 the diameter of your propeller.
  4. Use a ruler or calipers to measure the depth of how much you should trim from the opening for the propeller blades.
  5. If needed, also measure how much you should widen the opening for the propeller blades.
  6. Use a marker along with your measuring tools to create a cut line on the spinner dome, focusing on removing the propeller leading-edge portion. Try to blend the cut line with the arch of the opening.
  7. Cut and dry fit the propeller until you are satisfied with the fit.
  8. Balance your spinner with the Du-Bro propeller and spinner balancer.
  9. Balance the spinner backplate first by itself and then with the dome.

 

 

 

Du-Bro 101 – How to Set-Up RC Airplane Fuel Tank

Du-Bro 101 – How to Set-Up RC Airplane Fuel Tank

As we do with all the DU-BRO 101 videos, we want to take a task that modelers face and make it as easy as possible.  Setting up a DU-BRO fuel tank for your nitro or gasoline powered RC airplane is not difficult, but there is a procedure that should be followed to insure success.  

Below are the steps outlined in the video, please contact us if you have any trouble as we are always happy to help.

Assembling a Du-Bro fuel tank is not difficult, but you want to make sure that you get everything done correctly. Here is our suggested method for assembling a leak-free tank:

  1. Remove the center screw and disassemble the stopper assembly
  2. Input a 30-degree bend in the last 3/8" of the brass tube for the vent line. A Du-Bro Tubing Bender (part #785/786) works perfectly for this job.
  3. Cut a notch in the end of a short piece of flexible fuel tubing (1/2"-3/4" long).
  4. Connect the notched piece of flexible tubing to the bent section of the vent line.
  5. Insert the brass tube of the vent line into the rubber stopper.
  6. Insert the brass tube of the feed line into the rubber stopper.
  7. Use flexible fuel tubing to connect the clunk to the brass tube of the feed line. Size the fuel tubing so that the clunk is near the back of the tank, but does not get stuck in any position.
  8. Temporarily remove the flexible fuel tubing from the brass tubing on the vent and feed lines.
  9. Slide the rear plastic segment of the stopper assembly over the brass tubing on the vent and feed lines.
  10. Slide the front plastic segment of the stopper assembly over the brass tubing on the vent and feed lines.
  11. Insert the screw into the stopper assembly and turn it just enough to engage the rear plastic piece.
  12. Reconnect the flexible fuel tubing to the brass tubing of the vent and feed lines.
  13. Push the stopper assembly onto the neck of the fuel tank. Ensure that the stopper is fully seated.
  14. Carefully tighten the screw on the stopper assembly. Do not over-tighten.
  15. Perform a pull test on the stopper assembly to ensure that it is securely attached to the tank.
  16. Hold the tank up to a light. Verify that the end of the vent line is near the top of the tank. The clunk should be located at the rear of the tank.
  17. Install the fuel tank in your model. The vent line is usually connected to a fitting on the engine's muffler. The feed line is connected to the engine's carburetor.

Du-Bro 101 – How to Install a Remote Safety Ignitor on RC Airplane

Du-Bro 101 – How to Install a Remote Safety Ignitor on RC Airplane

--Video Below--

There's no need to place your fingers close to a spinning prop when removing the glow driver from your model's engine. Du-Bro's Remote Safety Ignitor allows you to move the glow driver connection to a safe and convenient location. The standard Remote Safety Ignitor (#793) works great on most 2-stroke engines. The version for recessed glow plugs (#794) is perfect for 4-stroke engines and others where the glow plug is less accessible. Installation is easy:

  1. Decide where you want to mount the connector housing. The location should be easy to reach when starting your engine and it must have balsa or plywood sheeting to support the housing.
  2. Drill a 3/8"-diameter hole through the firewall.
  3. Cut a 5/8"-diameter hole for the connector housing.
  4. Fit the Remote Safety Ignitor into place by feeding the connectors in through the large hole.
  5. Connect the glow plug clip to the post on the engine's glow plug.
  6. Clean the area where the ground terminal will be connected to the engine crankcase (example: engine mounting beam)
  7. Connect the ground terminal to the engine.
  8. Secure the connector housing to the airframe with 5-minute epoxy or GOOP.
  9. Seal the hole in the firewall with 5-minute epoxy or GOOP.
  10. Go fly!

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

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.

Du-Bro 101 - Servo Mounting for RC Airplanes, Cars, Boats, or Helicopters

Du-Bro 101 - Servo Mounting for RC Airplanes, Cars, Boats, or Helicopters

Mounting servos is a fundamental part of the RC hobby. We have a few tips to help you with this task.

1. If the servo comes with rubber isolators, use them.
2. Insert the brass grommets into the isolators from the bottom, so that the flange of the grommet is between the isolator and the model's mounting surface.
3. Set the servo into position on the model. Mark the locations of the mounting holes using a mechanical pencil with the lead extended.
4. Drill holes into the servo tray using a pin vise and a drill bit that is slightly smaller than the diameter of the mounting screws.
5. Consider using Du-Bro Socket Head Mounting Screws (part 893) with a Du-Bro 6/64" ball driver (part 442).
6. Insert and remove a servo mounting screw into each of the drilled holes.
7. Apply thin CA to the mounting holes. This will harden the wood around the holes.
8. Set the servo into position and secure with servo mounting screws.
9. Servo installation is complete! See DuBro.com for servo horns and other control system products.
