The MK Skymaster 60 must be M. Kato's answer to Hanno's Magic and Matt's Arrow since they are quite similar. This was in the pre-calypso days when the planes were loaded with equipment that you just had to have. Trike retracts, internal pipe, wheelbrakes, flaps, spoilers and the like. The Skymaster, like the Magic has a removable top to access the pipe. The Skymaster looks very small and fast from seeing the plans, it's airfoil is the thinnest I have even seen on an F3A model. I'd probably go for the Magic if I'd ever build one of these.
