On Sept 19, I went to fly with the Alamo Rocketeers over in China Grove.
Since my truck is broken, I went on my Harley Sportster with whatever I could carry in a knapsack. It's been a long time since I did that. You're limited to rockets that are either small enough, or that disassemble. Sturdy is important too. The Campitch 1 is certainly small enough once the flybar is removed. The hard part is getting by while leaving a new 25LB field box at home. It helps to have friends.

After ignition it's only spun 180 degrees and the wing is already extended for ascent at least part way. The pads' rod angle adjuster is slipping.
That's the wing in the foreground after bouncing off the ground, and tossing up a small cloud of orange soil.
The hub is falling after making a respectable altitude, wingless.
No major damage to speak of, but the cam follower pin was sheared off where it came out of the reinforcement plate on top of the wing. The pin was essentially a 2-56 steel bolt. I've already done repairs and replaced the 2-56 with a 4-40 socket head bolt, and widened the
camtrack slot to take it.
In retrospect it's not too surprising that something happened, given the number of MC's that come apart under centrifigal loads. I would've been much less surprised if the 2-56 pin was simply bent but still there. While I was at it, I installed the heavier return spring I had pre-selected as a possible upgrade. I never liked the limited wing attachment method on this model. A secondary safety attachment would be nice, but how to do it without making the next failure worse?
