I have an issue with spacing in the tunnel. I currently have the stock tubing and two AC hoses on standoffs crossing the spar. It turned out nice and snug.
Fast forward a year and I'm working on my avionics installation and wiring routing. My problem is I plan to put my headset jacks into my throttle quadrant/arm rest deal from Aerosport. This requires me to run about an inch bundle of shielded cables down the tunnel and up about 6 inches or so rear of the spar. I'm not particularly comfortable shoving those into the remaining space... concerned about chaffing on everything else there.
Reducing my scat tube to 1 inch over the 2 inch stock tube should give me enough space to get the bundle by. I just wanted to check my logic in that getting two 2" to 1." reducers and a length of 1" tubing will do the trick?
Also not worried about not having enough heat either. Flying my buddy's RV-10 I've used the heat twice, for about 20 seconds each time.
