Jet setter, they move as desired, just move too much. Even a small wind disturbance makes the model either zoom or go into a left spin. Interestingly it doesn't push down or go into a right spin....weird. One thing certain, it's practically impossible to fly which is a real shame. These small Guillows warbirds are really well designed and build into lookers.
I removed over 30 grams of weight from the parts during the build (around 30%), yet the model remained very strong. It has cartwheeled wing tip to wingtip almost every attempt at flight, and not a scratch. Over tall grass of course. I doped on light Esaki instead of the supplied tissue. Esaki is very strong and extremely light....love working with this material.
