Check out the Woody Valley Cosmic. A few guys at the flight park are flying them. It's sleek single suspension harness but isn't an all out race harness.

Hang gliding general :: RE: CG-1000 harness feedback needed

When a pilot goes upright with a standard harness he sinks into his leg staps and the harness scrunches up a bit to allow the pilot to get more upright. There is no scrunch with a backplate harness and it's not possible to sink very far into your leg loops because of the rigidness of the backplate. Single suspension harnesses also require some type of slider mechanism or the wouldn't get upright at all. The slider gets the pilot more upright but also hangs him lower in the control frame, giving him less flare authority.

I didn't get a chance to try a CG1000. When I ordered my harness Jordan was building harnesses part time and was not actively pursuing new orders. Several friends have flown them and gave them decent reviews. The cg1000 is an older design but is fairly sleek. I believe it has a tubular aluminum backplate but I could be mistaken here.

I have checked my Tenax as baggage a few times. The backplate was broken that way ($500 replacement). I would think that was a fluke except a fellow pilot shared that the exact same thing happened to him. Also, pay attention to how the reserve is connected to the harness. Make sure you are still connected if the slider totally fails.

My Z5 weighed about 20 lbs or approximately10 lbs less than my Tenax. That is with a Lara gold parachute in both.

It's a bit more difficult to run in a single suspension harness because they are so rigid. The backplate keeps you very upright for your run (not a bad thing) and the boot has more of a tendacy to hit your feet.

Since the main advantage is a reduction in drag there are not as many external pockets on many single point harnesses. My Z-5 had a lot of compartments I could access in flight. I could easily access my radio, camera, landing streamers, granola bars, etc. harnesses like the Rotor, Matrix, and Tenax have fewer external compartment. There is plenty of storage but it may not be accessible in flight.

Like I said, wanting one is reason enough to get one. They can be flown safely and are the preferred equipment for XC and comp pilots. A lot depends on the type of flying you plan on doing. Single point harnesses are very comfortable but have some serious tradeoffs. I wouldn't recommend them to a new pilot. Why complicate thing when you are new to the sport? If you get one be sure to fly a few times in mild conditions to figure out the flare timing.

Fly safe,
Dan

At least he was still walking around after attempting to go it on his own. Hopefully he realizes how lucky he was.

Day 4

5 more good flights from the small hill today. Actually there was another instructor there who was supposed to be working the big hill, and he told me he would have taken me over there after my first flight today except that the wind was coming over the back of the hill, so I would have been launching with a tail wind. Hopefully the wind will be more cooperative tomorrow. A north wind would be ideal, but the weather forecast is calling for SW.

Weather forecast for this evening was looking dubious so I went over to the LZ and got a tandem flight in marginal conditions right after we wrapped up at the training hill. Practiced some reversing turns, I think it was a worth while flight.

Went back for another in the evening but the weather was not cooperative.

A friend of my family, Dr. Robert Gumbiner, FHP Founder (an HMO) owned the jet that crashed in this article. Aircraft wake turbulence can be deadly.

I agree, as to the sources. The wake of any powered aircraft is about the strongest when at low speeds, with high power settings. That would include most aircraft, when climbing hard. With aircraft, the usual turbulence would be worse with wheels and flaps extended also, as in a missed approach (go-around), but nobody here should ever be near that scenario.

I met a guy this last weekend wanting some lessons after he bought an old UVed out Z-3 and a Supersport. Never saw the wing because he had already blew his launch in a 15 mph crosswind. Zero lessons. Purchased the glider and equipment from a SF Craigslist ad for $600. Said he took the money and said don't get hurt.I traced the ad and matched the name from USHPA member list. Expired since 2006.

Lucky_Chevy you really seem to be highlighting the negatives of single suspension harnesses and that's really helpful for someone like me also looking for a first harness. I'm seriously considering the CG-1000 and read a lot about here and elsewehre and I do have a few questions/comments that pops to my mind when reading some of your comments:

Quote: A single suspension harness will not go as upright as other harness types.

Did you try the CG-1000? Almost all comments I read about this particular single suspension harness is that it's very easy to put in the upright position. Maybe not as much as standard suspension harness but that would probably give a better position for finals (with legs behind), which is great for new pilots.

Quote: Single suspension harnesses are more fragile and can fail in new and exciting ways.

Could you develop? Examples?

Quote: Oh, backplate harnesses are also heavier. I fly a Woody Valley Tennax. It is one of the lighter single suspension harnesses at 30lbs. Some go over 40lbs.

According to their website shipping weight is around 15 lbs. Does a Z5 weight less than that?

Quote: It's a bit tougher to run in a single suspension harness when foot launching.

It's tougher to access gear in flight.
Again, why? Could you explain?

Thank you!

Our own NMErider installed dazzle tape on his keel, and maybe on a kingpost or two. You can see it on many of his videos. I like that it has a much more "widespread" pattern in reflecting light (with vibrant colors!) than straight chrome tape. It seems to work better when new, but it would be worth a "once a year" replacement program.

Ok, I just watched your video Janica. I would probably like to avoid that helicopter.

A helicopter in forward flight puts out a wake profile almost identical to a fixed wing aircraft of equal aspect ratio, wing loading and air speed. This is because the air mass "sees" the spinning rotor a solid disc.

The turbulence you need to Stay the "Holy Mother of God" away from is from a hovering or very slow flying helicopter. And remember, that turbulance will drift downwind. So, just like a person like me after eating spicy foods, its best to stay upwind. A helicopter in normal forward flight operations poses no particular threat to us and the alarm every time a helicopter is spotted is not called for.

Saw this happen at AJX @ 8:45 AMish on May 23, 2015. There were 2 pg pilots on the 750' launch when the 'copter did this.

As a relatively new pilot I am processing the recent rash of accidents and fatalities - too many just in my area, and in too short of a time. Struggling with just landing safely and wondering whether to continue is foremost in my mind. I knew Trey a little and was devastated and of course shocked to hear of his loss and can only imagine what those close to him are going through.

But two days later I got on the pony and had my best flight ever at a new site...this sport seems to be mostly dreams spiked with a few awful nightmares.

If you are standing next to the edge of a runway where large aircraft are landing you can hear the vortices go by.
