I spent a few hours heat smoothing this morning. I’ve been using the 21st Century model airplane covering iron that I’ve had for many years, but today the handle broke. I find myself applying fairly heavy pressure during the process, and it’s probably not designed for that kind of use. I mixed up a batch of JB Weld and reattached it, but it will be out of service until at least tomorrow. I relocated the headset jacks to eliminate the aileron cable interference problem. I moved the front seat jacks to the instrument panel, since this will make for much simpler wiring and shorter routing. I moved the rear seat passenger jacks to the area under the rear door post for the front door.
