Re: Gliding

Or just ditch the glider entirely...9min flight time might be a bit limiting but I suspect I don't have that much upper body strength anyway.

Yes, they're pretty common. Fold-away engines have been around for a while. There are two types - self-launching and sustainers (aka "turbos"). The difference is in their size & power. The sustainers are powerful enough to keep you in the air but not sufficiently powerful for a safe take-off. Up to recently all these engines have been piston engines with props, but it seems these little jet engines are becoming quite popular now. They have the BIG advantage that if you deploy them and the engine doesn't start (not uncommon) then they won't act like enormous air-brakes.

Re: Gliding

I guess they're the same sort of jet engine used in remote control model jet aircraft. And that is another world, see here for example.

Wow ! That's a very impressive model aircraft. The first one I built from a kit as a teen was an elastic band powered Cessna, balsa framed with tissue and dope covering. It took several weeks to complete the assembly. On it's first flight, I got as far as winding the elastic band via the prop 50 of the 70 turns required when the whole thing imploded

Models have come a long way since those days

Thanks for posting,

John

Re: Gliding

I wonder if this enters the domain of powered flight requiring a ppl (minimum); probably not due to the 'craft not being self launching. (Micro lights operate on a permit to fly, so maybe the same regs. apply.)

Looking at the video I think I've seen more 'thrust' from my wife's hairdryer, and / or the morning after a can of baked beans.

Using a hairdryer the morning after a can of baked beans could be an inflammable experience !

To infinity and beyond!

Can'nae take any more, Captain. The hairdryer is on maximum output - the long wet hair setting.
