What head protection are you using when Speedriding ?

Submitted by Stoylen on March 13, 2007 - 8:25am.

Thank you! My question is just out of interest in knowing how the glider will react in case of using the trimmers in flight. I do not want to try this out my self, and I do not see that I will ever need to either. Anyway - thanks for for your response <img src="http://forum.speed-flying.com/my-plugins/bb-smilies/default/icon_smile.gif" title=":)" class="bb_smilies" />

RE: trimmers during flight

Submitted by kitesurfa on March 12, 2007 - 9:54am.

I am no expert and not 100% sure what you mean, but...

Trimmers should be adjusted as pairs as they adjust the angle of attack or pitch of the wing. IMO should never be adjusted asymmetrically to turn the wing as you cant reposition them quick enough to re-correct. Also you will have to release the brake to do the adjustment - Not really the thing to do when trying to turn in the same direction.

Pull on the brake to turn, which should also put pressure on the riser which will help turn the wing quicker, as does weight shifting into a turn. Another key factor is flying speed - slow speed flight will give slow unpowered turns.

Trimmers control the amount of glide and speed you have.

Copy of text from the manual -
The front and back risers of the NANO are fitted with trimmers that enable the pilot to adapt the
glider’s behaviour according to his level and the chosen slope. Trimming the back risers makes
the glider smoother, more forgiving and slower, suitable for beginner pilots, or pilots who have
little experience. Trimming the front risers enables expert pilots to enjoy a more reactive glider,
with greater speed and lower flight angle, to follow steeper slopes.

alt loss

it varies depending on heading into wind when you initiate the turn and recovery, wind speed, wing loading is a huge variable, and how much you pull the riser down and for how long you hold the turn, air speed as you initiate the turn, and if your turning out of straight flight or as the pendulum effect from another turn has giving you momentum to turn. i like to keep all big turning manouvers above 500 feet until i get the turn down then i drop 50feet at a time until i get low with a long 2 stage flair for landing then start fine tuning my initiation altitude for the manouver and quicken the flair on landing to soak up the minor alt adjustment ( i'm describing a front riser 270 hook turn into a swoop landing). i'm heading to my favorite fly zone in b.c. at the end of january with the intent to get some exact numbers on different riser turns, air speed, trim settings and condition descriptions for the ozone xt16. but swooping is different every day depending on conditions even humidity can change the performance of a wing, so the numbers only have a vague relevance and is only accurate to the individual who has figured the numbers. but i will post the info when i get it for comparison. i'd be very interested in some performance info of different wings too. not much out there.

Hi Al

Would be great if you could post your "altitude loss" data for the manouvers - I would be very interested in seeing this data.

altitude

Submitted by alclark on January 7, 2010 - 6:28pm.

i like to fly with an altimeter so i can see how much altitude is lost with each manouver before i try things close to the ground. and try pulling on your risers just to simulate asymmetrical trim changes with out actually changing the trim. altitude is your friend while studying the behavior of your wing. the trim is designed to be changed during flight but generally isn't once you are familiar with the terrain and have a trim preference for the slope. i fly an xt16 and the asymmetrical trim doesn't react to violently but it doen't help anything. and riser turns are a lot of fun. rear rizers for flatter turns and front risers for hook turns and swoops.

xt16 no wind take off

Submitted by alclark on January 12, 2010 - 12:44am.

hey everyone,

I'm 93 kilos no rig, and just got my ozone xt16 off the ground in 0 wind on a 4-1 slope today! granted i was hugging the ground for the 5 second flight(short hill) but I've never foot launched on a slope so mellow. I'm 8 weeks off a knee reconstruction and can't even run fast, i just went out to do some ground handling and some test runs for the knee in preparation for a trip at the end of the month, never expected to get off the ground! just goes to show, ozone xt16 and attack harness gets the fatties up easy!

Perhaps this is a stupid question folks, but I have been wondering about something for a while, and I figure it's better to ask first before trying it out in real life.

I've been flying since 1994, but I have never had a glider with trimmers. How will a speedglider react if using the trimmers in flight? Pulling them evenly on both sides is surely not a problem, but what reaction will be provoked if pulling the trimmers asymmetricly? Will it turne more radical than when using the brakes? Will it become difficult to stabilize it?

This is a security question, not a "acro" question:)

I fly a Nano 14 by the way...

What Back Protection are you using when Speed-Flying/Riding ?

Submitted by alclark on Fri, 2010-01-08 00:22.

i have a go pro camera and i use a snowbard binding strap for ankle/leg mount. really comfy and easy to make espeacialy if you have old snowboard bindings laying around.

Details of how to build a Leg camera mount.

Click on above images for full size.

Materials Required:
1 x Aluminium Strip 130mm x 45mm x 4mm
Hama Ball & Socket Head 38mm - 5011 \ Depends on size of camera
Hama Ball & Socket Head 50mm - 5014 /
6mm wavey washer
1m x 25mm wide webbing for leg strap
2 x 30mm Stainless steel 'O' rings
High Density Foam strip

Instructions: Cut and form Aluminium as shown in above diagram. file smooth all edges and slots. Spray paint mount if required. Attach Hama camera mount with suitable screw placing the washer between the aluminium and the Hama 50## Cut webbing to 600mm and attach to one side of the camera mount. With remaining webbing attach to the other side of the camera mount securing both S/S 'O'rings together forming a buckel. Stick H/D foam to angled parts of the camera mount so it feels more comfortable when attached to your leg. Also maybe helpful to add vecro on the strap for extra security in flight. Add video camera and test... <img src="http://forum.speed-flying.com/my-plugins/bb-smilies/default/icon_smile.gif" title=":)" class="bb_smilies" />

Some locations require skiing to the launch site...

Bit of research on the web notice most poles are around 60cm in length (shortest length) are there any that can reduce to around 45cm - 50cm in length making them less of a Hazard when carrying them while flying ?

Anything much longer than 50cm does not fit in the Gin Speedflyer harness

What make/size of adjustable/telescopic ski poles do you use ?

What head protection do you use when Speed-riding ?
