One of our club's members is building a twin ducted fan powered puller. Because he doesn't have the necessary equipment, he asked me to fabricate the engine mounts and clutches. Here's the result of a day's hard work:

No they don't. Except for the engines, everything you see in the picture is custom made.

The gears are bought, but were modified to attach them to the clutchbells. They're made out of POM (Acetal Polyoxymethylene Copolymer)

First try wasn't a big succes. Here's what happened after about 10ft:
Tried again with glassfibre reinforced gears on the engines and a steel gear in the center. The sound of this thing (especially indoors) is incredible! You can actually feel the soundwaves!
Also tried a few modifications on the Wankel. It's sarting to run better every time:)
