aaaah.. i seem cant keep away from unusual planes...
Pegna PC1 was a design proposal for Italian Piaggio for the Schneider Trophy Contest 1921 by designer Pegna. It had a motor/prop who was tilted up for take off/landing. .. Same guy also drawed other seaplanes who was winners of Scneider in the early years.
This is a biiig posibillity im gonna build.
And.. LGF Roland was a submarine seaplane who could be disassembled and stored in "buckets" Looks kind of "stupid" with the big prop/cowl
weird, but fun, and not a troublesome build (if make big enough to get a battery inside.
