Thanks Mark I will give this a try and report back. My flaps are not flush either, I set them up with a digital level on initial rigging.

Flaps are but one item that can create a heavy wing - but easy to fix. Most overlooked (and fairly common) are low/high/in/out aileron brackets.

Recommend stepping back and spending some time to systematically rig your ship. Here is a post on how: http://www.vansairforce.com/communit...=165907&page=2

Don?t forget the wheel pants and gear leg fairings.

OK, so I adjusted the ailerons up so they are now even with the flaps. Sighting down the top wing surface, they appear to be reflexed by about a half a degree. Flew it this morning and I have picked up 3-5 knots. Not sure of the exact speed increase, but definitely an improvement.

Default Flap and aileron rigging

Flaps should be up against the bottom of fuselage; both the same. Ailerons should line up with flaps with elevators neutral and with a slight upward pull on both ailerons to take slack out... Tips should line up with the ailerons.
Heavy wing correction is another issue and is corrected in other ways, not by trying to raise or lower a flap or ailerons.

Default Flaps first

You really want to get this as accurate as possible. It is amazing that squeezing an aileron an imperceptible amount can make a difference. Imagine misaligned surfaces!!

Generally, get the flaps rigged first. The bottom skin flush against the fuselage. This is a solid baseline. Next the ailerons. Work and adjust the rod end bearing until you have perfect alignment. It may take a half turn at a time.

I like to clamp the aileron to the flap. This makes adjusting the rod ends easy. Adjust until the bolt will go through the rod end and the bell crank. Make sure the stick stay in the same spot!!! Don't forget to tighten the jam nut!!

Finally time to bring the tips into compliance. The alignment holes will generally be pretty close from my experience. Adjust the flanges of the tip to get the alignment correct.

Now work on the aileron to tip gap. Fun with fiberglass!!

Good advice (since the photos the OP originally posted indicated that the flaps and the ailerons are mis-rigged), but, this advice is only valid if it has been confirmed that the flaps and ailerons do not have an twist in them.

If they do, aligning all of the ends to each other may not be the best procedure.
