Hi from The Rockies in Canada. I am a paramotor and paraglider pilot for 28 years. Love your vids, great flying you did today., loved the low save over the river, the best feeling. You guys do lift in knots, thats cool. Most maintained lift on my pg I have been in, 10ms, to 10000 ft. Highest on pg just shy of 15000', ppg 12200' Blue skies friend, cheers Jerry

[@PureGlide]

Hey thanks for watching! I've got some more mountain videos coming up so you'll feel back at home soon :) Yeah we do everything aviation in knots, feet and miles, and then everything contest in km and km/h. The rest of NZ is metric :)

[@soaruk3697]

Get yourself over to Invermere and take a ride in a sailplane. Seen 2000ft/min in the Rocks and 16000ft. Guys fly up to 1000km regularly there...

[@joeevens1368]

Very nice. As a long time hang glider competition pilot, I can relate. No doubt that having a motor to save the day has opened the usable envelope considerably. Not dissimilar to the ability we have to work all the way down, still looking for the low save at or below 300 ft. We have been working microlift for several decades when necessary and have learned, as well, that it's not over until the ground comes up and makes us land. Yes, low cloudbase days mean close spaced lift, but on any day, the lower one gets, opportunities often increase as the small bubbles of micro drift along, join into lift lines, sometimes drifting for miles before building enough energy to make a real climb. This is where never giving up can make all the difference. It's the only way to gain the confidence to turn a 2 or 300 ft potential save into a great day. With that motor for backup, saves below 500 ft will become much more common for folks so equipped. As you say, It is quite amazing what lower performance machines can do. My current glider, An Atos VR, at 13.8 m span, can climb in a mouse fart and also handle the big air of the western US mountains. pretty cool, though it makes 20 to 1 at best. At 130 fpm sink rate and with an excellent circling polar, micro lift is real. I've actually had a handful of saves from 100 to 150 ft, and one below 50 ft. Many from 300 ft. Only the most stubborn of us even know it exists.... I've been enjoying your video's.

[@PureGlide]

Hey thanks for that! If only we could turn as tight as a hang glider sometimes :) I was flying with one the other day in a normal thermal, and *almost* kept up with his climb rate!

[@joeevens1368]

@@PureGlide Heh heh, I've spent many hours thermalling with sailplanes on the flats between Chelan, Spokane, and Moses Lake Wa. While I can hang in there with them at times climbing, when they decide to go on glide, it's like they vanish. I'll see one head off, and look for them the next circle, and they are gone. These are typically serious racers, flying contests in big air, so very high interthermal speeds...A few decades back, in the mid '80's, we were flying a contest out of Chelan, and the sailplanes were flying a big meet out of Moses lake, so our tasks crossed daily out on the flats. This is dust devil country, big and small, where it is not uncommon to head for a dusty that stands from the ground at 2500 ft to the cloud at 12,000+ ft. real boomers where you are sometimes flying thru chunks, dust, grass, small pebbles, etc several thousand ft above the ground. Anyway, one day I noticed a sailplane chasing his shadow around this big barren field that was trying to go off, with tiny disturbances swirling and disappearing. This guy starts diving the field, dusty's spinning off his wingtips, zooming up and circling, trying to trigger it. He hung in there for ten minutes or more, gaining a couple hundred ft a time or two, then diving again, before he landed in the field, which was typical, with fluffy dust and grit above the ankles to wade thru. About the time he landed, disappearing in the cloud of dust, it finally kicked off and got me up. Saved my day. Good times, Thanks for triggering the memory....JE

Fantastic videos, a few questions… what’s a good slow speed for long distance? And links to sites about cloud formations and best clouds for thermals? Thank you 👍🏻

Thank you! What speed to fly is a very big topic in itself, and depends on a lot of factors such as the strength of the thermals, how much water you have on, what height you are. But as a rough guide I normally fly around NZ at around 70--80 knots! As for clouds, check out the cloud appreciation society on facebook, that's a good way to see lots of clouds!

[@ukaszbarcik7025]

Great video, as usual! Having an engine gives you some comfort that normally you would not have and you actually mentioned that. I think this is the key that keeps your mind calm and focused on task. Would you glide into the ocean if you did not have it? I think flying glider with engine even when not used is mentally different than flying glider without it.

[@PureGlide]

I certainly did push myself in my DG-300 before this glider (with no engine), it depends a bit on the weather! In this case, not sure :)

[@Rickenbacker69]

I recently had the opportunity to fly an Arcus for a few years, and I found that the engine gave me the confidence to push much harder. I'd still set up for an outlanding before starting the engine, but I can't say I counted on having to land. The trick is to stay disciplined, and abort the flight at the same altitude you normally would, as if you didn't have an engine at all.

[@JohnVK5JAK]

Excellent video. I originally learnt to fly in Gliders in 1982 before moving to powered fixed wing and rotary. Why do you have two yaw indicator strings on the canopy instead of just one??
