Gray Beard, don't forget to add a 1/4sq hardwood along the side to bottom seam on the bay just behind the wings and also run some tri stock up the sides to former seam. A block between the wing hold down blocks is also good insurance. The other weak spot it the bottom to sides under the horziontal Stab. I snapped the tail off one when I stalled it on landing, dropped the nose and hit dead on the spinner, right wing and at that point the tail snapped off. This was my second 4*60
I snapped my first in half just behind the wing on my first solo flight. I came in to low for a landing and clipped the road across the end of the runway. Took out the landing gear mount and snapped the fuselage. I got it back to gether and soloed three days later.
I've got five kits in the garage now, but I'm really thingking hard about building another 4*60. I haven't had a good fun day flying since I killed my last one. Actually the day before I killed my last one
