Build Update:

The structure as shown weighs (IIRC) about 6g... I have no idea whether that is good or bad; but the real worry is that the electric and radio componentry is currently standing at 77g without connectors...........
Don't panic Colonel; the Sportster is a similar size (32" span) but has a lot less wing area than the Ajax (135 square inches) and is perfectly happy at 146 grams, I reckon it could easily be 20 - 40 grams more without impacting on the flying performance, so if you can keep it to 180 grams or less all up, which should be doable, it'll be fine. The Witch (36" and 170 square inches area) weighs just a touch more than the Sportster but is an absolute floater. For comparison the finished weight of the Sportster and Witch wings is 28 grams in both cases, so your wing should certainly be lighter than those.
