I am building the platt spit of platt plans I acquired. I plan to use a US 41. It will be built for every weekend flying so it won't have any scale detail to keep the weight off and lessen the number of snags. I have a set of roabrt gear that will adapt for use.

The one Platt Spit I have seen fly flew beautifully on a ST2500, an engine flameout and off field hard landing busted it up after it was in service for about 10 years.
