OK
After another full day trying to get the Ailerons set up with failed result. It is simply, I have too much down and not enough up on the both Ailerons. The results are
STBD
21.4 Up
22.1 Down
43.5 Total Movement
Port
23.1 Down
21.4 Up
44.5 Total
Should Be near to
22.5 Min to 25.5 Max UP
19 Min 22 Max Down
41.5 Min to 47.5 Max Total
Setup as by the book. QD’s in the Fuselage and the Wing root vertical Stops at 24 degrees before wings rigged and adjustments.
On trying to correct so there is less down throw by altering the long lateral pushrod in the wing in the opposite so it hits the stop, stopping the opposite aileron going down too far. OK now I measured the deflection it is now correct from its new position Not Neutral but slightly up. Now to bring the aileron back to neutral I have to shorten the aileron link rod. On doing so it puts the aileron back to exactly where I started from ???? Nothing gained at all just a waste of time.
All I have to do is to get less down and more up. What am I missing ???
AirEupora I have Used Buds method a few times now and yes it works every time for the first setup to get everything in the neutral position. BUT still too much DOWN and not enough UP
John, I’m getting within the correct ratio limits as you will see from above. It all just wants the deflections moving up about 2 degrees.
Any suggestions will be very welcome

Start with the short push rod in the wing , set it so that the aileron gets 23.5 up then hits the stop in the wing. (wing out of
the airplane.)
Next set the wing root bellcrank vertical with aileron neutral. (long push rod)
Then adjust the in fuselage push rods to match the wings with the wings rigged.
It's important that the aileron stops work and not the balance weights hitting the skin first.

Flying with a little bit of up aileron is not a bad thing, bit of washout but also reduces drag in the cruise.
I tried to line up the flaps with the ailerons. The print out of the section from Don's digital figures
gave a small amount of reflex at the trailing edge. Just like the gliders use.

I'm wondering what you are using for your neutral point. I followed Bud's suggestion and came out on the money, but it did take a couple of tries before using his method. Bud what’s you to use the bottom of the ailerons at the splint between ailerons and flaps. I used an electronic type of level.
The two angles in the fuselage have to be vertical. Then the two angles on the wings have to be vertical. Follow on out to the bell crank making sure you have full travel here and that the bellcrank is in neutral position. The ailerons will be the last.
I have read a number of the fellow Europa builders that fly with a little up aileron.

Bud
Thank you for your very Knowledgeable reply. I have now sorted out the problem. Well I say problem it was Myself that was more the problem and not the Aircraft.
In the end it was simply the Aileron stop in the wings. I set up exactly as you have described. When I rigged the wings, both Ailerons where in exactly neutral. All looking good.
Checking the deflection with the stick the STBD Aileron mass balance was hitting the wing surface on the down movement.
This is what I was doing wrong I was altering the long push rod QD in the wing root to try to correct the problem. After many attempts I discovered this does not work!!!!
After your setup description, I drew the logic out on a piece of paper and thought on simple term as to why and how to correct the mass balance hitting the wing surface. ( The ailerons are going down too far) It is quite simple, Just Lengthen the Fuselage short link rod to the QD bracket to plush the Port wing stop closer to the stop, as this stops the STBD Aileron going down too far and hitting the wing skin. This took a few attempts but I got it in the end.
Now Both Ailerons are slightly up instead of neutral. I correct this by small adjustments on the aileron link rod (as I had nearly 25 degrees up) Once Checked again I managed to get about 24.3 on both and 20 degrees down, these are within the limits and I'm a happy builder again
One point it will make is to use a bubble inclomiter ( The warp drive propeller incloniter is perfect for the job) As far as the digital inclomiter. I found a better use for it as my new workbench table leg.
Thank you far all the PM messages too, One builder had put together a few notes, this made setup much easier.
Thank you Again for every ones help

<?xml:namespace prefix="v" /><?xml:namespace prefix="o" /><![endif]--> Richard,
As you have found, setting 24 degrees as the up stop saves a step and a few riggings.
I can't tell you how many wing boxes I have ground out because of mass balance arms made too tall, or ill fitting wing boxes.
Glad you conquered the dragon.
Regards,
Bud
