Here's the airframe and rotorhead attached. Don't be tempted to fix bolts from above, as they won't be seen working loose. And as part of a pre-flight check, don't forget the WING-NUTS SECURE AND SET TO FLIGHT even if your FBO has already done so. Note that perimeter sections have been replaced after we'd used the previous to build the phone-box at the weekend. The box is 1050mm tall and airframe 1050mm square.
