It seems that every plane I purchase is discontinued within 3-6 months no matter the vendor.

Purchasing from Great Planes or Horizon is no guarantee ( I have a NICE GIANT U-Can-Do for instance purchased last year... try to get parts for that now! ).

Your best bet is to learn to do your own repairs.

IMHO Balsa planes are - MUCH - easier to repair then foamies and fiberglass planes.

As long as you can obtain similiar covering ( and even when you cannot, there is always a solution ), you can repair just about anything.

The problem is not the repair, but the time involved.

Some plane crashes are not worth it for me to repair. In those cases I pull of the parts and components and drop things into a new airframe.

At other times I may like the plane so much that even after a bad crash I may elect to repair it.

It doesn't take much to repair Balsa and ply, and stock is available constantly.

You can fabricate almost any cracked part, and in most cases you can use the broken pieces to put things back together like a big jigsaw puzzle ( picking up ALL of the pieces is WORTH IT! ).

There are plenty of guides and books available to help you out too.

Once you start making your own repairs, you'll wonder why you ever fretted about being able to obtain parts for a discontinued plane.

Also you'll have a lot of fun building your own "Franken-planes"!
