The 1st flight was completed. This informaiton may be useful to others wanting this airplane.
The recommended CG is 15mm in front of the main gear axles, I started a little nose heavy and set it at 26mm. With a fuel load of full the CG was 46mm in front of the axles.
Empty weight was 7.92 kg and full of fuel 9.39 kg.
Handling throughout the flight was fine. The ailerons and elevator were not sensitive. I started with 15-degree movement on each of these surfaces and will increase the roll rate for sure. I'll add 5 more degrees.
The biggest surprise is how much down trim is needed with full flaps, at least 5mm, maybe more. This is at variance with its bigger brother, which needed very little down trim with flaps.
