Thinkin' most of these folks are using off-the-shelf props "geared" to gas motor RPMs... higher reduction ratio and increasing pitch would cut tip speeds/noise. If most of these eppg developers have a gas motor history they're probably thinking this is "quiet"sk8norcal wrote:sounds kinda loud...
interesting, I have to look into that... don't know much about props...Lock wrote: Thinkin' most of these folks are using off-the-shelf props "geared" to gas motor RPMs... higher reduction ratio and increasing pitch would cut tip speeds/noise.
true, less vibration also probably...If most of these eppg developers have a gas motor history they're probably thinking this is "quiet"

In the United States that's just how it's supposed to be. These would be called Ultralights, you only fly those where there's NOBODY around, although people fudge that a bit. No pilots license or airframe certification required if the vehicle itself is under 254 pounds, but people fudge on that, too.parabellum wrote: Almost every time they start being noisy in populated area, they end up meeting local police, so to avoid that they fly far from civilization
The 19kw Green1 has a Lipo battery that can initially climb at aprox 500 fpm and can sustain the aircraft at a very smooth and quiet cruise for up to 1 hour with no pollution. Our other battery options can allow for as little as 20 minutes or up to 2 hours power on, which makes the eUP electric propulsion system ideal for self launch motor gliders or local recreational flying. Flight training to UL license will be available at the Freedom Flight Park near Lumby BC starting in April, and many other locations around North America soon.
See, this is why I waste so much time around here. I get handed stuff like this and it's all worth it. Amazing.grindz145 wrote:humanbirdwings.net
In marginal thermal conditions, use electric power to climb up into the spring thermals and have a good XC training sortie when other HG's and PG's can't stay up. Then fly home headwind on electric power. It takes 10 kW electric motor and 22 Ah LiPo battery capacity. And good old hanggliding flying skills. E-help - mountain launch only.
