Don't feel bad. This happens to all of us - "dumb thumbs", not thinking, etc.

As for the PT 40 - remove the dihedrahl from the wing. Change the landing gear over to a taildragger and move the CG back a little and you will have a "new" plane.

Put the AXLES of the LG even with the leading edge of the main wing. I have also had excellent sucess with Sullivan tailwheel assemblies.

If you decide you don't want the "hassle" of converting the PT over, take a look at the SIG 4* and World Models Rambler 30. Both of these planes will make an excellent 2nd plane and provide you with a nice aerobatic trainer to boot.

Remember, you have to learn to walk, before you can run.
