Default WINDRIFTER Craft-Air/Dynaflite

For some of us in the know, this was a great 100 inch thermal bird back in the day, and from what I have read was quite competitive against it’s contemporary ships. It was designed by Tom Williams in 1974 and has had a few revisions over the years. Although Craft-Air has been out of business for years, you can build it from a kit or find a plan. The neat thing about this classic sailplane is you can purchase a Dynaflite Butterfly for the complete wing parts, but you will need the plans for the fuse and stab. I have read that other companies are selling short kits and full kits to build this model from. For those of you who make lists of beginner or starter types of sailplanes, I think this should be on your list. If it’s a choice between a Windrifter or Gentle Lady, you can get more out of the sky from the 100 inch ship. This could also be a good choice after a first build on a two meter sailplane.

I have just completed building this Windrifter. I used wing parts from the Butterfly and then I traced parts from a Windrifter kit that I purchased from someone on the forum. It fly’s real well. It has very predictable manners and is soft and nimble in the air. For a big ship you can turn very tight circles and it responds quickly to inputs on the controller. Turn response is faster than with my two meter Sig Riser.

I had a chance to use a few carbon strips to upgrade/strengthen a bit, but not much.
At 46 ounces it flies very slowly, and I am enjoying this one more than my first one![8D]

Any WINDRIFTER stories out there? Any Info?

For those of you interested in a Wind Drifter, Skybench Aerotech makes a short kit of this classic. It sells for 78.95 + shipping. The short kit is laser cut and comes with the plans. Details can be found on Rays' site.

I built one in the mid '90s, built from plans, the only mod I did was make it a full floating tail, no elevators. It was a great thermalling glider, and would climb in the least amount of lift. with a bit of ballast (I used a bigger battery) it flew well on a breezy day, and could climb just pointed into the wind and trimmed. It was one of the gliders I really regretted selling

By the way Daja... Nice looking job on the drifter! Always nice to see a well built woody hitting the air. We need more builders and fewer ARFs!

I have a SD100 kit, it's a windrifter wing with a plastic Sailaire looking body. My friend used to fly one in the early '80s it flew very nicely.

Is there any company out there that has the plans to the Wind Drifter. I bought the kit in 78 or 79 and put it together but then through the years the wing got beat up and the fuse needs updating. The Drifter still flies well but now I'm putting in new servos with a new radio. Would like to get a new fuse but don't know who to contact. Any suggestions?

Thanks for the info, the wing is in pretty good shape (a few patches here and there) but what I am thinking is to swap the original fuselage for a Sailaire fuselage, to me  it looks better and may also perform better.

The sailaire fuse is way too big, you'll need the SD-100 fuse.

I had a copy of the Windrifter back when I was in college that I built from a Craft-Air kit & flew with a hi-start & a Kraft 3 channel radio. It was a great sailplane to fly, but it has been so long that I no longer remember what happened to that plane, even though there are a few pictures of it somewhere.

Flying weight depends upon how you build it, and what you put into it. The standard flying weight with R/C systems and batteries that were available back in the day ranged from 32-38 ounces.

Windrifter
99.3 inch Wing Span
916 sq in Wing Area
11.5% . . Flat Btm Airfoil
32 oz . . . Low weight / 5.03 oz/ sq ft Wing Loading / 3.87 oz/ft Span Loading
38 oz . . . High weight / 5.97 oz/ sq ft Wing Loading / 4.59 oz/ft Span Loading
9.22 inch. Average Chord
10.76 . . . Aspect Ratio
