Nick, I switched over to an unbraced design two years ago, mostly
because it's easier to build and transport. Since I use a V/P prop,
the model has to be built a little stronger. The motor stick could
be used for a 35CM and the model weight with a V/P prop will be
around .3 grams. It's hard to get these models to rise off of the
ground with a high pitched V/P prop and the launch technique is
critical. Wing warping and motor stick bend under full power play a
big part in a successful launch. Sounds like a handful; it can be. I
used to use a retractable landing gear but it was too much of a
hassle, and abandoned it. I use a single wheel up front and two
skids on the stab. The wheel has to be .5" in diameter and mine is
made from .003 boron with two boron spokes; .005ID hypodermic tubing
as the hub, and .004 as the axel. My prop is very similar to Bob
Bailey's 35CM prop that is shown in INAV Issue 113. The only
difference that I can see, it that my prop has two 00-90 adjusting
screws. The prop weighs .064gm and I use one similar to it on my
35CM.
