Nice. Looks like a very clean build. Great work on the covering, by the way. Much better than I could do.
I messed up the first time I tried, had a guy thats been doing it for 30+years help me with what you see,lol, he stood over my shoulder and got all drill instructor if I was doing something wrong.
Spend a little time gettting the CG right on this plane. The design sort of lends itself to being slightly tail heavy. At least my Tiger 60 AND my Tiger 120 were both tail heavy and the design is simply the same, but bigger on both cases.
I did a lot of research on the model before choosing the 61, everyone says they come in tail heavy so I just bought a bigger engine

If you look real close in the pic you can see the CG sticker still on the wing It is at 3-7/8 from the LE, the nose heavy side of the range. I had to place the motor a bit closer to the firewall then recommended but it works.
