Tim, my flaps were 0.4 degree out of alignment, but curing this didn't reduce the sideforce. The Gurney Flap is named after Dan Gurney the US F1 and Sports Car champion who discovered that a small lip perpendicular to the trailing edge of the then fixed racing car rear wings could be used to adjust downforce to suit conditions. Just try the web for a LOT of information. Brian Tarmar G-OBJT Book yourself something to look forward to in 2005.

And probably copied from someone else's application prior to that time. There's nothing new under the sun!

According to my memories it worked very well. I can't take the credit for that as it was Russel Lister who came up with the idea.... And it does work very well. For those who missed the original posting the technique is stupidly simple.... A light bungy cord connected to the control column leads from there towards the port side where yachting sheet(rope) clamp, attached to the thigh support, is used to hold the bungy in place. The aircraft roll is trimmed via a fixed roll trim tab so that the plane flies level with just the pilot on board. With just the pilot on board there should be no tension in the bungy. With a passenger on board you simply tension the bungy until the plane flies level and clip the bungy into the sheet clamp.
