Adjustments on Aquilla wing

Postby JACO » Wed Mar 25, 2009 9:27 am

Hi all. I was wondering, how does the different set points at the hang block, and spreader cable work ? What will happen if I change it, And what will the effect be on flight ?
See pic 1 & 2.

Thanx all ….

Speed. The more forward you move the wing the more speed you get. But also the engine revs go up and it has to work harder. Also the bar gets cloaser to your chest with every notch forward. If you are going to move it then move only 1 hole at a time and then fly it after every move to feel the difference and if it is comfortable for you. Each notch should give you +/- 4 miles in speed depending in which direction you move it. Y

Massimo is right in terms of speed, although speed is not entirely correct. I'll explain:

If you move the hangpoint forward, you merely change the speed at which you cruise handsfree and level. You will achieve the same speed as when you pull in the bar a notch. You will need higher revs to keep you level, and as result achieve a higher fuel consumption.

Spreader bar cables: The tighter you set the cables (On the pic, the further right), you will gain speed, because your sail will be tighter with a better airflow. You will loose a bit of balance, as you will reduce a bit of dihedral. The looser you set the cables, the slower you will be (2-3mph), but your wing will be a lot more stable.

Play around with your wing, and find the setting at which you are most comfortable. You can't break your wing. Just please do not go and drill extra holes in your wing. Only use those provided by the manufacturer.

NB: If you want to change the spreader bar cables point, you need to lower your wing to the ground. Don't let it hang loose. You will damage leading edges or nose plate.

The ideal of course is to be able to move it manually or electrically in flight. There are two brothers here in the Cape who make electrically movable hangpoints for trikes. PM me if you are interested. If I see them tonight I will try get some pricing

have a look here viewtopic.php?f=13&t=2227

Unfortunately Junkie is no longer with us :cry: :cry: , but this is the hangpoint adjuster I spoke about.

BTW he did not die in this aircraft, buth rather a Bush Baby. This one is still happily flying in the Western Cape

Hi jaco,

If you you tighten up the spreader bar cables you will also find the wing will become alittle heavier in the roll. I like to have that setting on its loosest to have a lite handling wing. By moving the CFG forward on the hang point you will also increase your stall speed. It makes the stall alittle more violent too. Looking at the pic you sent you have a well ballanced setting, so unless you just want to experiment I would leave it. Now, if you are flying on a solo X-country then I normally would move my hang point (CFG forward. it does work well for me, but its a personal preference. The reason why Solo Wings has so many settings on the spreader bar tentioner is because sails do stretch over the years and this will alow you to maintain the tention. When a wing is test flown at the factory its gets set for the best handling at 48-55 MPH.

Hope this helps
