Unique designs, what purpose (other than because you could) did each design have. The second one is certainly very unique. Where do you find the time to make all of those designs?

Second question first... retire 10 years early...

The first was an attempt for a long distance electric for the Baker Marathon. Intended to use 3 sets of 10x3000 Nimhs in parallel for the maximum flight time.
Gave up that idea after burning up two expensive motors and speed controls. It now flies quite nicely with a Speed 700 and a single battery pack.
100 inch span. The flying vee-tail was an interesting exercise in allowing for tail wheel steering...

The second is a first cut at an SAE lifter for the 2003 72 inch wingspan rule. The pylon-mounted wing got most of the airfoil as lifting, not enclosed in the fuselage.
Flies fine.. but the flaps were overkill.
I'm looking for a practical use for both of these.
