Looking good D. I was thinking the same thing with the bracing. I should have left a vertical section on all the pieces that get narrow about midway back on the yf23. They would have stood up better and matched up alot better. But its just a big learning curve going from balsa to foam
It's not too big a deal with the green ,blue, and pink foam it is kind of rigid I bet the white being a bit softer and lighter it probably moves around a bit more.
