This laser cut kit has a 54 wingspan and 594 square inches of wing area. It is for .45 to .53 engines. The EXTRA 330SC won the world aerobatic championship in 2013. The plans are CAD plans with full size templates of all the parts. The kit includes the landing gear. The kit does not include the control system hardware. The airplane will mount an RSM GRW 525U  5 oz. tank. The tank is not part of the kit. This airplane has a 17 % thick airfoil. The first kits will sell for $180.00 postpaid in the continental US.

Thanks,  Pat

IC version of the Extra 330 SC I will use either RO Jett .67 SE or Enya 50 SS. Very good Stunt numbers for this model even though it is
basically Scale.

I used 1/2 inch outside doubler and inside doubler for vibration this is a little variation from the kit. Note large 2 3/4 in Carbon Fiber Spinner.

Looking good Walter. The kit is Profile Scale. The shape was taken from the manufacturers literature. The full scale airplane is an excellent precision aerobatic airplane, so I don't know why the scale model will not be a good stunt airplane. It may not be as good as some of the top modern stunt designs, but it will be better than a lot of designs.
