Re: "Jet" pack
Thanks for your patience Dan, got it. I kept getting aerodynamic effects ie tail feathers on rockets confusing me. If hovering everything rotates round the COG quite happily. Light bulb on. The clever bit if you were DIYing a jet pack would be to integrate the laser ring gyro type auto stability fro...

Re: "Jet" pack
If the lift point ie nozzles are high above the COG won't that stabilize a flying whatever? Ruins the maneuverability of course. Hi Metiz, Just thought I would clear up some common misconceptions about Jetpack dynamics. Jetpacks are naturally unstable. There is no correcting force that will stabilis...

Re: "Jet" pack
The Martin Jet pack has just flown to 5000ft and been parachute recovered http://martinjetpack.com/Jolly good but this whole jet pack flying belt thing has me well exercised. First up I'd love to fly one I'd sign any waver / disclaimer and have at it. BUT There are a number of problems. Where are yo...

Latest from Laffin Gas. Carolynne persuaded me to write a summary of the technology they are using.
As for my having "an opinion worthy of respect." Maybe maybe not. I throw myself at the mercy of the court.

Re: Large holes tesla turbine toy for micro GT
Tesla turbines moving gases are considerably less efficient than a conventional staged fan or centrifugal impellers. On the hot end of a gas turbine they are a disaster as the thin webs and large holes make them structurally weak and very prone to warping / disintegrating.
