Dragon Fli is based on Slik Fli.
I have read the article about Slik Fli and it is described as "experiment to determine desirability of several aerodynamic features". The general feeling from the article is that the plane was "so-so".

Rainedave, is there any plan you do not have?
It would be nice to see that one for .40 size Dragon Fly. At least to know the wing area and if symmetrical or flat stab was propossed.

I have made some comparison:
(Plane / engine / wing span / wing area)

Dirty Birdy .60 / 64" / 688 sq. inch
Kaos .60 / 58" / 623
Dragon Fli .60 / 60" / 645
Tower Kaos .40 / 55" / 566
Peppemint Pattie .40 / 56" / 504

I guess .40 Dragon Fli should have wing area about 550 sq. inch
