You'll hear = it click, unless it's stuck. =20 Good luck. I'll just finished welding my exhaust system, which was = the last major fabrication job, so it's nothing but hoses and wiring to = make it run again. I expect to be making noise by the end of next week, = and maybe ready to fly by the end of the week after that. =20 Cheers, Rusty Glad to hear that the major stumbling blocks have been accomplished. = The hoses and wiring shouldn't be too difficult, as you already have = that T-shirt.
