Ken, Which Ultra Sport is best, GP Ultra Sport 40, GP Ultra Sport 60, or RCM plans Ultra Sport. I am looking to a next plane to build after I fly the GP Super Sportster I am building now.
Unfortunately the US 60 is sold out now. The US 40 is still available from GP and is a fine flying airplane. You would do well with it as it flies just as good as it's bigger brother.
