18" Dodo Delta
(2-pack) 2 planes for: $59.95 plus shipping *** Please choose USA or International shipping The drop down price includes plane and shipping. |
This EPP 240 gm delta was designed to fly with a quad motor by James our foam cutter at Crashtesthobby.
At Crashtesthobby if you design a plane you get to name it. Meet the Dodo Delta. The Dodo Delta flies amazingly well. Most sub 250 gm planes are boring but this one will wake you up. I am estimating the speed between 60-80 mph as shown. With the wingspan of only 18" The Dodo feels fast and aerobatic. See the videos below. Roll rate when set extreme is 3x second and it has vertical performance. At the same time it is a delta which gives it great stability at lower speeds.
The planes below weigh in at 220 gms with battery and paint. The nice part is that the entire weight of the foam parts is only 60 gms so it should be easy to keep it under the 250 gm all up flying weight. It is not designed to be laminated but possibly could be and keep the weight under the 250 gms, The problem with laminate on a delta is it adds a lot of weight behind the CG and makes the plane hard to balance.
As with all of our wings this is cut from EPP foam. This delta is 18" wide and a 12" chord with a fat 14% symmetrical airfoil. With the thick 14% EPP symmetrical airfoil the Dodo Delta flies like a much bigger plane and can handle a lot more power and weight. Speed is much more consistent all the way through loops and rolls and other aerobatics than a flat foam plane.
The Dodo Delta is designed to fly with a quad motor and small servos. As shown they are flying with either a 2230-1780 kv motor or a 2204-1800 KV motor with a cut down 7x6 prop to a 5.25" length. They have about the same power output and vertical and are fairly quiet. It has 5 gm servos and a 6100 Spektrum receiver with a 12 A ESC and a 450 mah 60C 3 cell battery. Flight time is about 5 minutes with the 450 3S battery.
The Dodo Delta has big elevons so they don't need to move more than 1/4" up and 1/4" down on both elevons and elevator. I have my dual rates at 50% and the planes are still fast and acrobatic. The motor is set at 0 degrees thrust to the center line of the wing.
The colors are Krylon for plastics red or orange and black rattle can paints masked with duct tape.
Deltas are sensitive to CG. As shown I am flying with the CG back 4" from the nose of the plane.
We are still setting up the instructions but the plane is simple and straight forward.
Glue the two cores together and use a glue hinge on the elevons.
The plane is small enough that with the nose mount motor no spar is needed. Keep it light.

I just finished a new video on the symmetrical airfoil Dodo Delta build. This time I laminated it. I did a high speed video so it isn't like watching Jello set. This plane was a little harder to trim and I had to add 1.5 ounces of weight to the nose to get it to balance and track well but now it will fly hands off. It is sensitive to the big elevons and I have the elevons moving about 1/4" to 3/8" up and down. Elevons set with top of wing and elevons flat with little reflex. See video above.
