Here is my new Carlspad. I wanted to build a sport / pattern type plane. The wing is actually developed from the wing on my Edge 540.
Wing span = 60" Wing Root = 12" Wing Tip = 10" MAC = 11.03 Area = 660 sq. in Wing Aspect = 5.45 CG = 4.5 Weight 6.25 lbs Wing Loading = 20 oz/ft Wing thickness max 2" tapers to 1" at tip Wing spar one piece popular with 2 degrees of dihederal
Fuse length = 55" Horizontial stab = 22" Vertical stab 12 base 7 at tip including rudder
The plane is powered with a .61 ASP The plane flies very well, it does loops, spins, knife edge, axial rolls Plane has very mild stall, nose drops slightly, with no wing tip stall Landing speed can be slow, likes a little power on I have 50 + flights on this plane with no problems or failures

I Thing It's Not pure SPAD
The idea that drives Spad is use what You have to get in the air. Look close, it's more Spad than You think This one was built by ChrisSpad and it's pure Spad.
The Carlspad is made completly from coroplast, except I used balsa for the ailerons to save weight and add stiffness. The frame is made from 1x 1/4 popular attached to the firewall running back to the stat of the wing saddle. I used two pink foam formers for the back of the fuse. I made the turtle deck from foam covered with sign vinyl.
