The Marks Models Windward was my first "real" radio controlled glider (sailplane).
It had a 72" wingspan. My old
Digitron 3-channel radio went into it at first, and then
was replaced by a Cirrus 4-channel rig. If I recall correctly, the Windward lived
two lives - one before the big crash, and the other after (which also eventually
succumbed to a big crash). The covering for the first incarnations was silkspan
and dope, and then Solarfilm was used on the second. Solarfilm is not sold any more,
and as I recall was nowhere near as strong and stiff as Monokote. However, as with
most aspects of my aeromodeling back then, the choice for covering materials was
based almost entirely on available cash.
I would like to acquire a Windward kit for old-time sake; it will be preserved
and never built. Please let me know if you have one you are willing to sell. Thank
The plans and kit parts are shown below.
The AMA Plans Service offers a full-size version of plans at a very reasonable
cost. They will scale the plans any size for you.
Here are a couple photos that I pulled off the Web.
