    My all time favorite rocket is a tube rocket conversion of the Estes Vagabond. It has canted tube fins and a 29mm motor mount. It has flown with a C11-3 to a G64. I believe it's H capable but haven't tried it yet. At least I'm not sure if I did. A CTI 3 grain H54 White Longburn would give it quite a ride. All this to say that since I like the basic shape so much I would like to use an upscale for an L3 attempt in a few years.

    In preparation my plan is to build a couple of smaller upscale and work up to the big boy. The first will be based on 4" tubing. Why? Because I have all I need in the garage. It should be a relatively simple build (famous last words) which I hope to launch at the Tri Cities Rocketeers Sod Blaster 2 this labor day weekend.

    Decision time! 38mm or 54mm motor mount? :):cool:
    Here is the dirty original with the nose cone skewed a bit:

    How does it all fit in there? By storing the chute in the nose cone.

    This rocket has flown around 35 times. It really scoots on an AT F42-T8:)

    Very nice! Be aware that if it's light enough you can get well into the transonic ( and possibly just beyond ) with, for instance: g76, g76, g80

    EDIT: disregard, I had thought we were MD but I think that's a retainer tail not the case itself.

    I saw the rocket earlier today, it is an Estes PS series 29mm retainer on it. Looks like a fun upscale, go for it Derek!

    Bingo! I checked my notes and it did fly on a G76 which delaminated one of the fins. The tube fins have 1/64 ply lining on the inside to provide extra strength. A bit of tape to seal the leading edge will solve the problem me thinks.

    Rich, I found another section fo 4" tubing so I have all I need to proceed.
