i have spoken to mfg on a carbon tube for this jet and this should be tons stronger than the alum thin wall it comes with. since i have a 180n in it lets be safe and use this.
anyone want to buy half left over that will be enough for a second plane i wont need. im sure i can cut down the shipping tube and sent it back out to you once mine arrives next week..half cost with re ship will be about 100 bucks if anyone wants to step up and join in on a better upgrade for safety..heck my top model odyssey has a much larger and thicker wall tube than this pilot jet has stock.
