My earlier plan was to make up the radiators from balsa - the plastic ones are >1.2gm apiece - but the weight savings came at an unacceptable loss of robustness and those that I deemed "robust enough" saved only 0.1 gram raw. The beast does use the protuberances to land on, so I did end up going for the plastic. Remaining to do - cockpit, pilot, canopy and exhaust stacks - and, of course, paint.
Another small test hop with 250 stretch-wound turns on the 4 x 3/32 motor (at the flying patch this morning) scared the bejesus out of me! Gradual climbing right turn with only a slight bank up to about 30 feet, then straight as an arrow toward the dreaded Blackberry bush (landed thankfully 10 feet short)! There was no sign of tip stall or any other problems typical of the breed - and it was a bit breezy.
Weight for today's "fright" - 60 grams (no canopy). A bit heavy, but there is a LOT of wing...
