Andrew Donatelli, aka Bipe Flyer, has designed a plane very similar to the Kadetito called the LST (Lynn Sipe Trainer). It's in the sticky at the top of the forum called 1/2A Trainer Anyone? Plans in both zip and pdf version can be found on page 33 of the thread, plus on page 1. A lot of folks have built this plane and all have been very complimentary on the build and flight characteristics.
