Update on Werner’s Blackburn RC Model

 

Following is some additional information from Werner on his build of the 1912 Blackburn Type D Monoplane RC model. Plans for the Blackburn are available here.

Werner enlarged the CAD Blackburn plans 125%. The RC model uses three channels of control. No ailerons are installed as the rudder is used for turns. This approach works well for the model’s slow and close in flights.

Werner reports his Blackburn tips the scales at 0.585 kilograms or about 20.6 ounces. This is an ideal weight and wing loading for this larger modification. You can see the results in Werner’s flight video.

Werner installed a 2S 1300 mAh lipo battery to power a Roxxy Bl Outrunner 2220/12 electric motor. Flight times are around 12 minutes.

Enlarging a plan is a great technique if you want to adjust the size of your finished aircraft. You may have to substitute some wood sizes from the original plan. This is not hard to do. Always ensure you have adequate strength while not getting too heavy with excess structure.

Werner constructed one of his models from the Sig “Pioneers of Flight” series of kits. This includes the Demoiselle with my build here. By enlarging the CAD plans of the Blackburn, Werner’s rendition is around the same size as his other two models.

Adding a pilot figure to any model plane is a good idea. Having a pilot in the cockpit makes the model look “right” in the air.

Werner did a nice job hand carving a pilot out of lightweight balsa and foam. The addition of some paint makes the final figure come alive.

The large cockpit control wheel is a nice touch as well.

Spoke wheels help with the appearance of these antique flyers. Spoke wheels were used by just about all of the early aircraft. A spoke wheel offers a lot of strength at a very light weight. This was an ideal approach for the under powered aircraft of that era.

Aircraft in those days typically spent little time moving at high speeds on their wheels. The aircraft of that era had short takeoff and landing runs.

Pilots rarely conducted extended ground operations. Under these operating conditions the relatively fragile spoke wheels were a good solution.

A small amount of attention to an RC model’s dummy engine adds a lot to the visual appeal. As with the addition of a balsa “engine” to my Fokker Spin, Werner added balsa cylinders to replicate the Blackburn’s engine. Low vibration electric motors make these modifications a snap.
