Maiden time!
OK the plane is not finished yet, this was just to make sure things are on the right track regarding CG, engine cooling etc.
It went really well, AUW is 8 kg dry with only 250gr in the nose. The plane is slippery and aerodynamically balanced, combined with low wing loading makes a very easy to handle warbird that has a very gentle stall (no wing drop, I tried hard as you see on the video) easy take-off and landing.
Engine still very rich as I'm half-way through the 4 litre break-in, but no problems with cooling
