Spreader bar tension

[DarkHelmet]

Once again - that bolt at the back on the Aeros 14.9m2 wing.

I had Jenair out at the field and he told me that by loosening the spreader bar tensioning bolt the trike would perform better in the roll but should be slower. Did I hear him correct?

My wing has two "latches" to tie on to the bolt - one latch slightly shorter than the other.

By tightening the spreader bar I will go faster but will experience more bumps (this is my thinking). Have it in the first tightest spot now - should I expirement by tightening it more by going on to the second latch?

Usually after 100hr's plus you could tighten the sail more. It will improve your glide and the wing will definately be more responsive in the roll. Lighter controls. Up to a certain point the tighter the sail the better. The wing is more effective and you will have less drag. Better fuel consumption.

Yip, as KFA said,

When the wing is nice and tight, your airfoil is cleaner. Those ripples on the top of the wing creates drag, thus increasing your stall speed. If the airfoil is clean, less drag, thus lower stall speed and a increase in groundspeed.

Something else that can clutter the airfoil is if the little ropes at the trailing edge is not tight tight when over the battons. If not correct this will cause ripples and again the increase in stall speed.

To true. Be carefull, sometimes the wing becomes so clean that you hardly feel the neutral position and easy to stall if the experience is lacking. Happened to me once when I thought I knew it all and nearly saw my arse. Moved the hangpoint full foreward. Not one hole at a time. BIG mistake. Always make small adjustments at a time. You can always land, adjust and live to fly another day.
