Yes, I know, not so cool as a pulsejet but here we've not so much room to throw long long flames

The LAPU fits my Seagull Miniclub fibreglass axle, I guess the Ludic half axle too but I've to try yet.
I took an old grass trimmer engine, some parts with a rubber wheel from the clutch of an old moped, some old plywood to join the engine to the rubber wheel with that sort of ninepointed star and to build a very simple frame. A rubber band (new!) keeps the driving wheel on the landyacht wheel.
Nothing new, just a try to make things as easy as possible.
