  • Thermy 4: Project Cancelled

    Sorry for the lack of updates. Today I’d like to announce that the project “semiscale-soaring plane based on Thermy 4” is cancelled. With this project, I overstretched myself (again). The initial idea of a modified nose grew into a complete redesign of the fuselage… and the wings would benefit from some changes as well… I’m […]

    Thermy 4: Planning the Fuselage

    After drafting a first version of the nose, there’s work to do on the fuselage. So this week, it’s going to be a lot of frames to draw.

    Thermy 4: Planning the Nose

    Based on the design variations, I’m moving on to the actual planning and start to blueprint the nose. If possible, it is supposed to give the aircraft a semiscale appearance and that means I basically have to start from scratch. In order to create parts repetitively and precisely, the blueprinting is going to be computer-assisted. […]

    Workshop: Building Boards for the Thermy 4

    In order to build the Thermy 4 I will need building boards, which are in widespread use with model aircraft builders. They serve two purposes: First they are supposed to provide an absolutely even surface because most workbenches sag over time, which means one can’t build really straight wings or fuselages on top of them. […]

  • Thermy 4: Design Modifications

    As already mentioned at the start of the construction report, I’d cast an intermediary eye on the Lentus Thermik by Multiplex. I especially like its semi-scale appearance, that gives it a similar look as modern soaring planes. Most notably the bulbous nose and the T-shaped tailplane are spectacular and provide a great silhouette during flight.

  • Thermy 4: Make a Wish!

    Since I’ve braced up and actually want to build the Thermy 4, I want to begin with getting clear about one thing: What do I actually want? The question isn’t quite as trivial as one might think. I’m planning big on this airplane. That is, I want to incorporate as many features and wishes as […]

  • New Construction Report: Thermy 4

    In March 2019 I happened onto an issue of the FMT, which included the first part of the diagrams for the Thermy 4. Right away, I knew: That’s what I’ve been looking for! The model incorporates everything what I’ve wished for: great wingspan (4 metres), take-off weight below 5 kilograms so it’s legal to fly […]
