Believe it or not, surprisingly, they Fly well ! I made the T-34 Red and white Low wing trainer. I expected it to drop like a bar of lead cause I painted and detailed it, but it was onme of My mostr sucessful Rubber motor Planes . I do not do many, but have done almost all the ones that are supposed to be Rubber. Like the Javelin, etc. The Bird Dog 900 was My best Rubber powered flyer. So much so that I am currently making a 40" WS Dumas RC One. The ones like The Javelin surprisingly did not Fly as I expected. I am no Rubber expert, Dihedral, by its very nature, must decrease lift the more You add. I'm no David Lewis, but even I can figure that out. I did a second Javelin, lowewred the dihedral on the Polyhedral wing, changed the tail/wing Decolage(added shims on parts I may want to adjust), used My own balsa from LHS, and a FAI size rubber, and prop with help from Mitch, and it did MUCH better. Than I joined a Club, and they're all RC, or Quadcopter Guys, and have not really messed with rubber power lately. But the newer Laser Cut wood is a big help in weight. As for your weights; I only dream of getting one with kit wood, and tail design that light. Oh, and not just the Bird Dog, but all the Cessna Guillows seem to do well. I think it is their Wing shape. But thats just My guess. If anyone knows why they do Fly well compared to similar Planes, plkease tell Me. Sadly if I choose to do a Rubber powered Plane, and I was seriously competing, it would not be a Guillows. But for some reason I Love their kits. Maybe cause It is how I got My start into the Hobby. They do not advertise much in periodicals, but they are in every Hobby store I go in. I remember the 50 cent stick ones in a bag. They Fly awesome too! Even RC conversion is a simple task on them. Anyway, good luck, and I wish I could see the photos, but apparently there are problems here as I have seen other recent posts about the same thing.
