Hi all, Icompletedmy Pica 190in about 1999 and I just pulled it out of hibernation after 10 years .I just rejoined a club and I have it on a couple of videos on youtube

A seperate ply chamber for the manifold to sit in was fuel proofed with epoxy. When in the plane you can only see the flared tips .An attempt was made on a scale looking tail wheel with a hacksaw , dremel etc which is suspended on a medical syringe for a shock absorber .MY Eff Dubya weighs 12 pounds with 3/4 oz cloth and resin airbrushed panels rivets etc. and ispowered by an OS .91 surpass which believe it or not flies it with no probs. Awesome plane I love it!
