Actually the fact that Hobbico has discontinued all of their sticky-backed covered ARFs is an enormously good thing. I've got a Kyosho P-51D ARF with this type of covering and it absolutely SUCKS! If you puncture your only repair remedy is packing tape, it's very weak compared to any iron on covering including the lightweights like TowerKote, the seams come undone, and when it sags heat don't shrink it. I'm counting the days before I rip all the covering off and cover the entire plane with some real iron on covering.

As for 60 sized trainers, take a look at Sig's new Kadet Senior ARF or World Model's Super Frontier Senior.
