Jim,

I know about the motor mount mods that need to be done but haven't heard about the "magbox" mods you mentioned. What's happening there? Thanks for you time and I wish I had listened to you earlier (oops). "Experience is what you get when you don't get what you want". Kevin

Thank Rich for all his help, send it back and try to get a refund. Don't waste your time trying to make another Skytec work. I tried that three times. 2. Buy a B&C, have Bruce Bainbridge upgrade the motor to a 320, no charge(better for high compression)and install it. 3. Go fly! The B&C starter has worked perfectly since the install. The modification to the mag box was simple and the motor mount only needed to have one corner cut off the pad. About 10 hours work, start to stop. As I've said before the B&C starter takes much less power to run it. Hopefully I've put the starter issue behind me. You can do the same. Sorry to hear of your troubles. I do understand!

My email was filteringemails without attachments and I didn't realize it.interest to many regarding Skytech starters.Skytech told me and after discussing what seemed to be the problem with Jimwell, but had more of a "grinding" sound in operation than I would have liked.After a 10 MAXIMUM total starts, in a hurry to get the airplane to an avionicsshop (onfield), I forgot to turn on the fuel, and, after a very shorttaxi, the obvious happened, I ran out of gas. Duh!!! I turned the gas valveon, waited about a minute, then tried starting again. The prop turnedfor somewhere between 6 to 10 seconds before the engine caught and Itaxied on my merry way. A couple of days later, I picked the airplane up,jumped in to start it, and was met with what seemed to be the grinding sound ofgears with missing teeth (the engine did start, however).find a tooth missing from the Skytech starters drive pinion gear. That wasthe bad news. The good news, I was able to find the tooth. (I thank the Qgod's for that one.)and they did all they could to help. I can't complain about their customerservice. Skytech, but as of yet, I have not installed it. All my mental alarms are goingoff related to something that can throw of a piece off big enough thatit could gum up my engine (read off field landing and/or a damaged engine)or at the least break off a tooth on the crankshaft gear, which at the least,is going to be damn expensive.kickback. control of the centerline distance of the pinion/crankshaft gear set. In an effortto loosen the tolerances in the manufacture of the starter, Skytechhas allowed the pinion to get too far away from the main gear on thecrankshaft. This results in an incredible force trying to separate the gears. Thisforce than further deflects the shaft that holds the pinion, which leads toeven higher forces on the gears, then ultimately to a broken tooth.the centerline distances this weekend and I will let you guys know whatI find. Please take it as so.know the ratio.worse. feeling to good with this right now. Quickie Builders Association WEB site http://www.quickiebuilders.org Yahoo! Groups Links
