Thread necro:
I built one of these exactly as shown on in the Model Rocketeer, with the stab on top (while wondering about the line in the text about the aft launch lug being on top of the stab), with a lifting airfoil sanded in as best one can in 1/32 balsa. It had its maiden flight yesterday and it didn't do well....nice straight high boost on a 1/2A3-2T. But then it came straight back down rather than transition to a glide. It was trimmed to glide rather nicely (I thought) from a hand toss. I've replaced the crushed nose cone, but based on Fred Schecter's post (and what I saw) I think I will try to move the stab to the bottom of the tapered boom then re trim it for glide. I'm not sure how Wolf's redraw works with the 1/8 square spruce fuselage, so no taper toward the tail...or is there a little? The basic concept of a sliding pod is so simple that I'd love to fly something like this at NARAM this year, unless Jim Pommert can convince me to go the no moving parts route....

If you're having trouble trimming a slide pod, which introduces a huge CG shift, I'm pretty certain that trimming a no moving parts glider is going to be a lot tougher, given that the CG shift there is substantially less. My $0.02; YMMV.

Gee thanks, Bunny..... I've not done rocket gliders before....I think this is my first that isn't one of Frank Burke's RC RGs, on which one does the trim change via the radio. I can build to plans, but if the plans are not representing the actual working configuration of the aircraft, well...that's what this thread was originally about and where my questions still lie with exactly one flight's worth of free flight RG experience. Jim Pommert has already shared some details about how NMP gliders are set up and I am likely going to give that a try as well.
