The cat’s out of the bag — and here’s what our team has been working on lately. Introducing the RV-15 Engineering Test Prototype aircraft. This airplane was built to evaluate and test the design, and what we’ve been learning from this engineering “tool” test airplane will result in refinements and changes that will appear in the final “kit” aircraft design. You’ll have a chance to learn more about the prototype airplane during our forums on Tuesday morning at AirVenture in Oshkosh, coming up in just a couple of weeks! Source: ‘Van’s on ‘Youtube‘.
