Subject: Re: Carbon rods in Dubro micro "clamp" for the servo..
Let me did around and look through my Bug file and see what I have. What in particular would you like to see? I didn't do anything too fancy. Just a small section of 1mm SS wire as a leader off the servo arm with a V bend for adjustment and the spring is currently a T bend arrangement. I originally had a Z bend spring but the twisting forces from that made the hinge want to delam and was starting to cause warpage. So... I went to the T bend and that solved a lot of troubles. Much nicer setup. Let me know what pics you want to see and I'll get them up, (even if I have to take them new) Heck, can't have too many pics of a Bug can you? --- In BugHLG@yahoogroups.com, John Gallagher <gldrgidr@...> wrote: > > Mark, > I was just about to ask if anyone used the string and spring method.  Any chance that you can upload some photos to the groups site? > I also debated about using a pull-pull setup using Spiderwire (non-stretch fishing line). >   > John > > > ________________________________ > From: Mark Stephen <mark.stephen16@...> > To: BugHLG@yahoogroups.com > Sent: Thursday, November 17, 2011 10:16 AM > Subject: [BugHLG] Re: Carbon rods in Dubro micro "clamp" for the servo.. > > >   > On my Bug, I have used string and spring. The "pull string" is .009 music wire (guitar string). Also use a piece of that same wire for the spring in the hing. Works great, and no mucking about with small bent or broken push rods. > > --- In BugHLG@yahoogroups.com, "gldrgidr" <gldrgidr@> wrote: > > > > Laurie, > > The teflon tubing is the best, but there is a lower cost alternative to the teflon tubing. It's Sullivans Gold-N-Cable #507. The yellow tubing works fine for the .020 to .024 piano wire that I recommended. I don't know if it's available on your side of the planet. These are available in most hobby shops in the US. > > Don't use the braided Sullivan cable that comes with it - very heavy. > > > > John > > > > --- In BugHLG@yahoogroups.com, "kb11troy" <kb10troy@> wrote: > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > Laurie- > > > > > > John is right about the thin steel pushrods- they need housings. I used .018 music wire in etched teflon tubing on mine and it works superbly. You can see the details in the photos I posted under "Rick's Bug". The music wire in tubes is a competiiton style DLG technique, but it works great in the Bug too, and is very light but relatively tough. The only place I know of to buy the tubing is Tailboom.com. It's not cheap, but if you buy 20' it'll last you for many, many Bug builds. The music wire can be had by purchasing single unwound guitar or banjo strings of the right diameter at a music store. Anything from .016 through .020 should work fine. > > > > > > By the way John- I didn't start the Bug thread, but I and Mark61(and you of course) have been doing our best to keep it alive. > > > > > > The Bug is a sweet little plane and about as much fun to fly as anything I know of.
