All you have to do is take a razor plane to the LE and rough shape it. Takes about 3 minutes.
I made a sanding block from a piece of 4" wide x 12" long countertop board. It's pressed particle board. It's 3/4" thick. Since it was manufactured in a plant. It's been pressed, glued and cured under heat and pressure--it will never warp. 4x12 is the perfect size to wrap a sheet of sand paper around it. 3/4" won't flex--no matter how hard you push. Long sanding blocks don't cause warps in your LE or sheeting. Short sanding blocks are good for Martha Stewert.
After you shape the LE with the razor plane, all thats left to do is sand it. Start with 80 grit to knock off the majority of it and give it shape. Go to 120 to clean up the groove marks left over from the 80 grit. Finish with 400 grit.
The whole process shouldn't take more than 10 or 15 minutes per wing.
Whats the big deal? It's a $125 kit that was designed 20yrs ago. Where ya gonna find a kit that size and with that much heritage and nostalgia associated with it for the same price? Where ya gonna find a huge trainer with a flying stab and enough square inches to accomodate engines from .46 up to 30cc? Where ya gonna find another kit THAT cheap and it flies THAT good?
Stop whining and build it.

It will be beautiful when your done. They fly so sweat, it's almost a sin. The Senior Tele makes a perfect "mule" plane or utility plane. You can load it up with all kinds of accessories and it won't even notice the weight. Camera mounts. Skis. Float mounts. Glider hook. Bomb drop doors for candy or other cool stuff. Test plane for new engines. Night flying.
BTW--Mine is on the way. I won't be building it this season. I'm probably going to build an 80" Midwest Citabria first.
