Chris, Tom,

A 2-3 inch span of the 1/8" Cf tube will be enough to stiffen it up. It only weighs a couple grams tops with the glue. I just put a 35 inch section on my scale at it is 7g

So is you use 3" sections on each side its only 1g in CF plus the glue. The result is really rigid and nearly no weight. I tried it on my model. I took the titanium ends off with a little heat and then slid the 1/8" tubes over the top. A little thin CA down the tube will secure it well and I used some med to build up some fillets like at the ends of the hollow tubing. then sanded the CF rods ends and reglue the ends in place.

If 2g is too much weight to add loose some of that thread you stuck on the balsa sticks. I used about four 1/2 inch sections to tie the tubing to the balsa sticks. The tube doesn't need to be a mummy inside the thread just supported to not move.

I used the teflon sleeve material from CST. Works great. I also have a small 40 size model I used the system with and used some 0.050" CF rods with dubro antenna tubes for guides worked well. These smaller rods got a little flex and I just installed some short 1/8 in sections at mid span. Now its stiff and solid.

Model looks really good. I'm curious on the AXI motor.

I had plans to make my Brio E power but after I got it from Central I was very disappointed in its quality of both materials and workmanship. I may do a Genesis however I'm not a big fan of chip airplanes either.
