Peter, In regard to your first critique, please have another CLOSE look at the information supplied. You will see that the drive motor is located directly between the two main wheels. On first inspection, this appears to be a very elegant solution.

Subject: Re: [Aus-soaring] Glow sailplane I still like the single main wheel, preferably fixed. Simple, cheaper, robust and can't land wheel up. Yes it is tipped over at the start of the take off, but wing can be raised as soon as airspeed is sufficient. which might not take long with the wheel motor. Q4. Is the tail wheel stuck on? Seem s like this is a simulation at this stage. Turbofan required instead of turbo jet. Unfortunately nothing on the market yet.

I've thought about 2 single wheels a little further apart. More complex mechanism. Q2. Where is the jet air intake? Top of fuselage behind canopy. Pop up intake. Q3. Is the jet thrust sufficient for climb out? Should be but I'd like a little more while preventing running the engine at more than 80% thrust for longevity and reliability reasons. My rule of thumb is Thrust weight or around .18 to 0.2 so you can get 0.14 to 0.15 T/W without running engine at 100%.

I've though for some time that dual wheels and electric taxiing are a great idea although I'd have made it a taildragger with steerable tailwheel.
