The Different Delta - for Sport, Not Speed

There have been many delta-winged models over the years, most of them designed for speed, but the Delta Vortex is different. It combines the user-friendliness of tricycle gear, nose-mounted engine, functioning rudders, a thick airfoil, and low wing loading into a beautiful aerodynamic machine that is incredibly aerobatic without the blistering top-end speed. When it's time to land, pull the nose up on this stallproof delta wing and put all those square inches to work slowing it for a picture-perfect, nose-high touchdown every time. Don't let the radical shape fool you - the Delta Vortex is an everyday sport model at heart.

For much more detailed info on the Delta Vortex kit, be sure to read Bruce's article "So What's So Different About the Delta Vortex?".

R/C Report    October 2000
"...enjoyed playing at both ends of the large speed range. While I can outrun most of the sport planes at our field flat out, with the use of the split rudders as speed brakes, I can also 'outslow' them on approach or flybys too."

R/C Modeler    October 2000
"Compact but big. With all this size are some powerful flying advantages. Besides stealing the show from your flying buddies, with a truly unique flying wing, the Delta Vortex's large size helps it to fly smoothly, more like a conventional airplane. The large size is also easy to see, even from a distance."

Model Airplane News    January 2001
"Landings are very amusing; you can set your approach very high and let it settle into the runway hands-off; the glide slope is that flat. Some trainers don't handle this well."

Flying Models    June 2001
"The balsa parts and sheeting were the best I've ever seen in a kit... The ribs, which are the single largest parts in the kit, were perfect... The kit is complete and all the parts fit perfectly together."

Fly RC    December 2005
"The extensive manual leads you through every detail of the rapid construction. I've spent more time assembling some ARFs! Bruce Tharpe has created a real jewel of an aircraft."
