Dude, you cant get a pipe for that Bird for 3 hundy, and if you could, it would add what, 5-7hp? I'd spend $300 for 15hp all day, especially if I was adding that 15 hp to 50.
I've spent alot of time in lifts and can attest that your internal danger alarm would be going off in light wind. Big gusts should have you shitting your drawers and getting that thing down asap.
