Cliffwhacker is the new flap-equipped slope sportster from Alex Whittaker's drawing board. It was the free plan with RCM&E's Jan 2015 issue with a follow-up article in the new March issue.

Easy to build, the model is a perfect sloper and handles a variety of conditions. Those who hate cutting ribs and formers will be pleased to know that a set of laser-cut parts and a wood completion set are available from the Plans Service.
