Das Cerberus (oz15715)

About this Plan

Das Cerberus. Radio control triplane model, for 3x .19 to .25 engines.

Note this is not a plan for a complete airframe. This is a plan showing how to modify the original Das Ugly Stick (oz5175) design, by building it upside down and then adding 2 more engines, creating a low-wing triplane.

Note this here is currently the best copy of the plan we have, greyscale at 240 dpi. The plan appeared in Airborne magazine 1981, a time when paper print quality was terrible (see article file). If anyone out there has a clearer scan of this plan, we'd love to see it.

Direct submission to Outerzone.

Quote: "G'day Steve and Mary. Following recent discussion on RC Groups about a Twin Stik I remembered my tri-motor low wing version that I designed when I was a bit younger.

With 3 x OS Max .25's I christened it 'Das Cerberus' after the three headed dog that guarded the gates of hell. Well it actually was not a dog but flew very well as I used the throttle stick to control the wing engines and a separate servo channel (on a Tx slider) to control the nose engine.

This meant that if I lost power from a wing engine it was simply a matter of throttling back the other wing engine and opening up the nose engine which enabled the model to be flown safely.

In fact, the model in the photo was flown in some r/c streamer combat events (three props eat a lot of streamers). Once when I lost a wing engine the other flyers lined up for an easy kill - until I closed the nose engine throttle, gunned the remaining wing engine and Das Cerberus pirouetted on the spot and the hunters became the hunted ??

Probably easiest to use an Ugly Stik plan for the basic dimensions and incorporate my modifications."
