The reason Scott Benedix, SWB, Inc.(one of our club members) arms does not offer 1/16" holes in his arms anymore is simple.....much like the nasty stuff Tam is going thru with his pipe collapse deal and possible law suit threat, Scott was spooked by a couple of Giant Scale pinheads who threatened to sue him when they had a clevis pin failure using his arms with 1/16" holes rather than 4-40 taps.....he did a run of about 100 or so of those couple of years ago.....

This pin failure may have been real on those vibrating 40% birds, but probably not a problem on our jets.....BV has switched over to H9 metal arms on the UltraBandit flaps, but cautions that the pins have to be precision fit into the arms which he offers as pair from BVM with the new UB's or as an upgrade on older ones......this AD came out after David Shulman stripped one or two JR 215's on one of the airshow UB's.....

I much prefer the SWB locking arms over the H9 versions.....My machinist buddy, Paul Jacques, up in Oshkosh, has milled/machined a couple of SWB 1 1/4" arms for those of us locally that fly UB's and precisely drilled holes that are a perfect no-slop fit....then we keep them lubricated with axle grease and some teflon powder......should last forever......I am also converting my JR 215 elevator UB/P-180 arms to SWB with 4-40 ball links......that is first plane I have really thought it might be necessary due to weight just under 50 lbs wet, high-G yanks and banks, and 200+ speeds.....all my other BVM jets have done fine for years with the 215's.......

In the future, Scott may come out with an arm for 1/16" clevis pin, but with a Delron insert to protect from vibration......but it is on the backburner right now, since his 4-40 arms sell like hotcakes.......lots of jet and prop guys still think they are the best of breed, and he still is a bit gun shy as these, win-the-lottery-type-lawsuit pinheads are always lurking......
