If anyone needs a SF-4 mag, I have one that I am planning on bring toSun n Fun to try to sell. It will have a price of $60 in the Flymarket.From my past experience the Fly market is much better at SNF than atOshgosh.Dick Navratil________________________________________________________________________________

WaltIt is a SF 4 LN-8 with the drive gear. It has a great spark. I picked itup for my plane but ended up going with a new slick system. I am trying toget what I paid.Dick----- Original Message -----

If the magneto advertised is a Bendix-Scintilla SF4 it will bedirect drive only (no impulse coupling). The Bendix S4 mags,on the other hand, could have an impulse coupling or be directdrive. The S4 is a newer design.My book on the SF4 isn't handy as I write this, so I cannot pro-vide any other details at the moment. These are sometimes called "box mags" because of their boxy appearance. They are big and heavy, but are very reliable and produce a strongspark. Some parts can be difficult to obtain (Aircraft Sprucecatalog has an exploded view of this magneto and they can supply a few parts).If you wish more info. on them, I'll dig out the book (hope I canfind it!).Graham Hansen (Pietenpol CF-AUN)________________________________________________________________________________

Dick,The best I can make out of the AS&S manual is that is a left hand drive mag,and the A65 needs a right hand drive. does this sound right? Do you turnthe gear to the left or right to "snap".thankswalt----- Original Message -----

I may be interested in your SF-4 mag. I have two but expect to need parts. I willbe taking them apart for inspection in the next few days. I cannot attend Sunn Fun. Perhaps I'll know my specific needs before you leave.Dave Boyd, Champaign, IL
