All the input on the "Heavy Wing" has been great  ,and I'am sure it 's been beat  to death.As Columbo says "Just One More  Thing" Does any one have a pict. of one on  a plane? Is .025 thick enough  ?  About how long and how wide,and how much is is hanging off the wing? Pop  rivited?   I just want to get it right Thanks again to you all  !!                                              Joe N101HD 601XL/RAM

just put an aileron trim on it.  Zeniht sells a great kit for it.  most planes this size have a heavy wing situation, just trim it.

Before you rivet it to anything make a small tab and use aluminum tape to  hold it in place then keep tweaking it untill you have the size and angle you  need then rivet it on. It doesn't take a big tab try not to go overboard on your  first try. Look at some rudder tabs and start there.

again, longer and narrower is usually better/more effective than shorter and wider. More tab area bent to a shallower angle is usually better/more effective than smaller tab bent to a greater angle.

We didn't have a heavy wing problem largely because we put the battery on  the right side in front of the rear spar and probably the most helpful was off  setting the main gear 2 feet to the right....... O no!!!!

Members,

      When I had my ZodiacXL built I was  sure that I would need wing trim so I ordered it to be installed.  This  aircraft is so small and light that just the pilot if he is a big guy will  cause the left wing to be low.  Also a pasenger who will be on the  right side of the cg will sometimes cause the right wing to dip so the  only way to insure that you fly level no matter heavy pasenger, or what  ever, if you have a trim tab on one of the wings, this can be corrected. I  would advise all builders to install wing trim so you have a way to adjust in  flight.

A couple of comments - 

1.) Twist in the horizontal stabilizer can also contribute to a rolling tendency as will asymmetrical wings or any errors in rigging.



2.) Careful fuel management (to reduce weight in the heavy wing) and sticking some weight in the "light" wing's baggage compartment (if you have one) can be helpful as well.  You'll get better overall performance if you don't have to crank in a lot of aileron trim.



The wing heaviness problem described on this forum is not unique to light aircraft like the XL.  I had to add an aftermarket electric aileron trim to the left wing of my C182 (2950# gross).  It had 40 gallons of fuel (240 lbs)  in each wing when topped off and tended to "lean" as fuel was burned.  Without the aileron trim the Cessna 300 Autopilot didn't have the strength to keep the wings level.

I flew with Bob in his plane a few weeks ago, he trimmed it up to the point  it was stable hands off. That was the third 601XL I have flown in, one of them  had no trim and it was uncomfortable to fly. Personally, I wouldn't build one  without the Zenith electric trim, in my opinion, it is well worth it.
