The Hangar: Dart
Finally, after 3 months of nonstop technical difficulty (with a brief respite by the Polaris), this bird is finally airworthy. It is made of dollar tree foam board and colored packing tape using Experimental Airlines building methods.
The fuselage pod is 2" external diameter, which is a very tight squeeze, and 20" long. It is tapered down at the nose and up at the tail, and the bottom has clear acetate to toughen it up for landing. There are popcicle sticks going through the pod for wing tie downs
The wing system I am very proud of. It has two interchangeable wings. Both are 5" airfoil chord armin wings swept 22.5 degrees, but one is made from sweeping 30" sections and one is from 20" sections. So, there is a 33" and a 49" span wing for this plane. The 33" is a solid piece, and the 49" is in two halves with folding vertical stabs. When you take the spar out, it can be used to lock the two wing pieces together. The result is very compact. Both are secured to the pod with rubber bands.
I am using the same gear as always, GH supersonic on a 6x4 with a 2200 or 1600 3S. With the 2200 full forward, it balances on the 33", and full aft it balances the 49". AUW with the 2200 and 49" is about 20 oz, given the thrust to weight, and has a wing loading of a mere 8.4 oz/sq. foot! Should be a blast, pics coming soon.
Did the maiden. Word of warning: this calculator lies. It put the CG about an inch behind where it should be. The 33" just plain didn't work, and the 49" barely survived.
All fixed. As expected, the 33" is speedy and agile, and the 49" glides like a dream, gave a Calypso a run for its money.
Status: Completely intact, blown out of range, inaccessible, on an island.
Now gone, floating around in NY bay somewhere.

The Hangar: Polaris
This one needs no introduction. 100% scale, depron, GH 2212-06 motor and 40A ESC (grayson accidentally sent me a 40A instead of a 30A)
. The only differences from stock is that the spars are in an A-frame configuration, because I didn't have a single carbon long enough, and there are plastic spoon air intakes. A canopy has been painted on since the taking of that picture, and it won the Foam-Tac Contest!
Status: Decomissioned (Shredded by trees. Found it hanging a few feet off the ground by the guts, looked really cool.)

Plane rack
Just got a new rack to hold planes. A couple of 2x4's (lumber, not props) mounted vertically on a wall, spaced 2 feet apart. 1/2" dowels are set into them at a ~10-20 degree angle pointing up, and they protrude 18". The result is a set of prongs that wings and sheets of depron and the like fit nicely on. Hope this is useful to somebody.
The Hangar: P115
P115 as seen on my avatar, given to me by MeanBaby, pylon racing him at the field. (he technically won, and therefore must be crushed) There is a thread on it in the scratchbuilt forum, I think.
31" span, solid bluecor covered in packing tape, coro hatch and stabs.
GH supersonic V2 on a APC E 6x4 with a 2200mAh or 1600mAh 3s lipo. My second real scratchbuild, the construction is a bit naive, so there is a high parasitic drag coefficient. The top speed in level flight is about 50mph, way short of the motor's potential.
