The advantage of the aircraft derivatives for power generation is their extremely fast starting.

The company I work for have some Olympus (concord) gas turbines and have no gearbox. The engine is used as a gas generator and they run another turbine in the exhaust stream that connects to the generator.

How do you go about parts for the 503 like a crankshaft as Rotax no longer supply parts? I believe Rotax don't want them pressed apart and rods and bearings replaced. I don't think there would be enough room for an endoscope to do a good inspection of the big end rollers and journal.

Does anyone think that RAAUS would do some work on sorting making it easier to replace the 503 and 582 on high drag ultralights now it seems they have the airspace access and heavier MTOW sorted. While these engines can be rebuilt, I would be worried about the condition of crankshafts (roller bearings) which don't seem rebuildable. (parts etc) Seems like the current process at the moment will price these aircraft out of existence. Is it possible to build a Drifter or Thruster out of second hand parts and call it home built?

Good for domestic, has large limitations for industry, jobs for our kids etc

Can you just drill a small hole in the top of the perspex and see what happens.

Regarding headsets that fit under helmets, catch up with a local cross country hang glider pilot. They have some pretty good setups now days.

Welding leads from a welding supplier make good jumper leads. Not sure the insulation is made of. lots of very fine wire to make it flexible. Available in different sizes.

I think they were 8mm, but can't be sure

Hi, Can we list the instructors who teach in thrusters?

Thanks Evryone.

Hi Everyone, Just wandering what material the windscreen is made out of on a Gemini and how thick it is? Thanks

Found this the other day, interesting development. Could be Nuclear powered as well.
