TRF,
Our goal is to complete construction on 31 January. That is just two weeks from now. A lot to do in short time.
Progress is made on the booster (tail unit). First we fabricated a frame for both assembly and shipping. It is made from 1-inch steel tubing and locking castors. Note the booster is 120 inches length and 117 inches span. It weighs about 220 pounds. We think the frame is a good investment given the boosters scale.
The assembly frame is pictured below. Note second photo where we added A-braces on either end along with some corner braces. The fame is quite stiff.
Servo boxes are built up including internal X-braces. Those appear strong and tough. Still we may fill those with 3 pound density foam. There is a lot of momentum in a near 300 pound booster landing 15 feet per-second.
Rudder boxes are also built. Those will be foam filled pieces considered sacrificial bumpers to an off center booster landing.
This coming weekend is devoted to skinning the booster. Will be our most challenging piece.
