Default Wing Spars

I recommend have the carbon spars handy when building the wings and installing them during the build. I was a bit impatient and found that the holes for the Carbon spars were too small, so had to remediate later.

I purchased a 1m length of 14mm Carbon wing tube (2mm thick) with a 16mm outer sleeve. The length was fine. Donít put it all the way through or it will get in the way of the thrust tube.

Lucky I had the wing tubes before assembly of the second half, it was much easier to enlarge the holes in the frames while the kit was still in pieces.
