I’m in that wonderful honeymoon design stage where everything is possible and even major changes can be completed in half an hour.
I’m referring to the Tiny Cedar Flea, of course. I currently have two candidates…
My first design candidate was the open cockpit version. Which has been joined by a closed-cockpit contender. Different airframe shapes, but wings and powerplants identical.
Oh – and the current preferred powerplant is the OpenPPG 33hp equivalent electric motor. With a second battery – over 2 hours of flight time.
Your preference?
Both designs have their merits:
For example, the open cockpit version is simple and easier to build.  It will be constructed in two parts:  Both top and bottom halves are basically the two halves of a normal cedar strip kayak.  But it is also (being an open cockpit) quite draggy, and I’d expect a poor glide ratio because of this.

On the other hand, the closed version is more “racy”, far cleaner aerodynamically, will glide much better.  But because of the closed-in cockpit with a hinged canopy, much more difficult to build.  It is also a bit more cramped, and probably won’t accommodate larger pilots (although a “XXL” version is quite easy to design).
Both have identical wings:  front: 4.4m, rear: 5.8m, with a combined wing area of 12.25 m^2.  In the old language, this equates to: 131.8 ft^2  And that’s a lot of area for a plane with an empty weight of about 120kg (265lbs)
As for power, the OpenPPG electric motor (33hp equivalent) is advertised to give 70 minutes of flight (in a PPG – which are notoriously draggy machines – after all, they are dragging a huge parachute behind them).  An amply-winged airplane should do far better than this.  Even so, 70 minutes isn’t bad.  But if one hooks up a second battery pack (20kg) and switches to the second pack in mid-flight, one gets 140 minutes (minimum).  That’s 2hrs 20min.  Not at all a bad endurance.  I’m very comfortable with this.
So it comes down to preferences:  sleeker profile or cheerful and open?  Ease of build.  Glide ratio.  And the comfort of a closed cockpit for those less than balmy days.
I’d be very interested to hear your thoughts on this.
