Quite a few replaced the steel bar with a CF tube for the weight savings.

There were different versions of this CMP MQ-9 Reaper kit sold.
V1 came with a steel bar for the wing spar.
V2 came with the carbon rod. There were aluminum and carbon tubes for the V tail spars

I have built the V2 and wanted to beef up the wing supports.
I chose 2x12mm carbon bar to go completely through the fuselage instead of gluing in the
short aluminum bars for the wing attachment. That gave me more peace of mind after watching some of the video's.
Some looked like ornithopters in the air! Wings just flapping and the fuse undulating... eventually just dropping out of the sky.
I personally would like to see an 8mm carbon rod a foot longer in the wing. A hint for the carbon rod in the wing. Identify the spline in the carbon and place it up to give the most resistance against lift. This resulted in some anhedral while on the ground but should result in a more stable wing attitude in the air.
I posted a pic of my turret solution. Very simple. a piece of carbon rod, 2 wheel collars and 2 supports. I also built a hinged battery tray for access to camera and turret underneath. More pics upon request.
I also modded the nose gear. Wanted it back a little farther with more forward sweep to at least be a little closer to scale.

Hope this helps!
By the way, the plane pictured is for sale. Completely built with detachable wings. Never flown airframe only. On the Eastern Shore of Md.
