Between my addiction to Deltas and my addiction to speed I kept thinking of what would make the perfect Delta. It seems that the Delta’s I am aware of all seem to have shortcomings so I made a list of what I would change. While a Delta may never win the German Speedcup, I have not seen any real attempts to be competitive. I may not be qualified to design a world champion speed plane but basic issues can easily be addressed.

This Delta is my design and my goal is to have a very clean airframe that will fly really fast or really slow. Most Delta models either have everything out in the breeze, weight too much or both. Deltas look good by default so making it look even better should not be hard. These were my goals during the design phase.

1. Reduce all drag. Drag is enemy #1 to speed so a clean design is important. (easy full engine cowl)
2. Low weight. Heavy airplanes do not fly well and it increases drag.
3. Build in a couple of days, not weeks or months.
4. Cost $100 or less to build.
5. Look good.
