Kolbers,
I just finished my "Uncle Craig designed" boom support, with my own modifications. Since my ailerons do not unhook like the usual method, I did not need the tall support shaft, to carry the ailerons. My ailerons are secured with their own cushioned frame, and cinched down to the boom support in the provided hooks.
I made my wing support pads with the ability to "rock" a little, to allow for slight differences between the wing's and the pads. Another change I incorporated are little tabs on the back side of the main square tube, to allow for a tow bar. My intention, eventually, is to actually tow the plane , fully assembled, to my local airport. At least, that's the plan...we'll see. The entire cost of this version of my boom support was very close to $75, and about 2 1/2 days to build.
Also, I have included a photo of the main wheel dollys I just finished building (I have two). I had made a fairly small cheapo set out of wood, with small castors, and they didn't work worth beans!! This set is made with much bigger castors, steel channel frame, and the wheels end up being much closer to the ground. Total cost for the castors, scrap steel, and paint...about $50. Not shown in the photos, yet, because I haven't rigged them, is the orange strap binders for each dolly.
If anyone wants any additional photos, email me off list. I have several more photos available.
Credit goes to Uncle Craig for the design. I just saved myself a quite a bit of work by copying his stuff. BTW, those castors (on the boom support) are the smallest pneumatic tires I have EVER seen. They actually have tubes and a valve stem. They weigh very close to 2 pounds, for the tire & wheel!! Cost for each castor was about $9 (ea), IIRC, from Harbor Freight.
I have separate photos of just the wheel, if anyone is interested.
