Hi,
[sm=72_72.gif] Did anyone change the setup for the elevator servo. I really don't like the 2 push rods attached to each other with collets. [sm=spinnyeyes.gif]
Any ideas or suggestions? [sm=49_49.gif]

I don't like that setup, either. Maybe I'll go with two servos for the elavators.

I don't care to use colletts to join the wires. I feel that they could come loose, and the wire could slip.

I'm sure there is a way to prevent this. I'm not quite to that point in the assembly process. I'll dig into it when I get there.

I'd worry about the wimpy tailwheel assy first. Mine broke during a crosswind landing. Got a leafspring setup for 18 pounders now. The elevator works great, and im only using a Hitec HS-425BB.

I used two wheel collars, and there is no way that they could ever come loose. Thats one thing im very sure of. I cranked down real hard on those phillips head screws.

I was thinking about wrapping the wires, and soldering the joint, or two servos.

I understand what you are saying. I usually fly larger models. The GP method is not acceptable with them. I may be worrying about nothing.

My first GPSS died when a tx was turned on during approach, sniff sniff, and thats the one that broke the tailwheel prior to the interference crash. I went straight to the leaf spring setup on the replacement Stearman. That wire would be fine on a 40 size plane, but can't take the abuse of of a non perfect landing on the Stearman. I landed, was rolling, got hit by a cross gust, plane spun 90 deg's, tailwheel wire broke right below the lower hinge. That was the only time I ever had to walk to get this plane back to the truck. I don't have a kill switch yet, so it just sat there pointed into the wind idleing until I could get to it. Leafsprings rock !

Ya, it's a cheap setup. I like the leaf spring units from CB Assosiates, and use them frequently. This time, I'll use a DuBro unit, that I was going to use on another project.

Tell ya what... put 2 collars on there, and crank down on those screws good, then decide. Aint no way their comin loose... Just position the rods so that their side by side when ya thghten the screws. Using 2 servo's is a fine idea, but I don't think it's an issue. Ya have to do what makes you feel secure though.

Thanks. I'll look at it more thoroughly when I get there.

I was hoping that would be today. Late, yesterday, I discovered that one of my ponds has a leak. [:@] I need to get that fixed before I can work on the Stearman.

Only way to go really. I've had 5 or 6 TW wires break in the 6 years i've been flying, but have never broke a leaf spring setup. The one on my Stearman went thru that awful crash, and only the wire was bent slightly. Them dudes are tough as nails !

That sounds weird (leaky pond) I'll take your word for it though. Is it large enough to float fly off of ?

I've never encountered problems with them either. nI bought the DuBro unit because of it's appearance, liking the yoke. I'll give it a shot. If it doesn't work out, I'll replace it with one from CB Associates.

Maybe I could fly a Park Flyer from it. A very small one. It's a plastic pond, from Home Depot. Something happened when I cleaned it yesterday. It held water before that.

I'd rather work on the Stearman.

Im always lookin for a slicker setup. I think the guide bushing could be atteched to the main leaf better on mine, but so far, it has not come loose. Im sure is will eventually though. I'd feel better if it was silver soldered, brazed, or something.

Never had a problem with that. I don't think it's a concern.

Who's worrying now???

Hahahaha ! I was really scratchin my head here over that leaky pond.
Park flyer... I think your onto something there... My bud just recently gave me a Folker triplane. I still need a Lipo and 2 micro servos, and a small 33 crystal. More fun !

Time for a Stearman fix.

I think the Stearman is the coolest looking biplane ever made, but thats just my opinion...

Is that yours?

If I remember correctly, this one has a 26cc powering it.

I just mounted a G-23 in mine. I expect similar performance.

Think I'll head out to my shop. Although the motor fits completely within the cowling, the plug and wire will protrude. I need to make the proper cuts to accomodate this.

Tom,
For what it is worth, I used the wheel collers to make the initial set up then feed them throught the opening in the firewall, wraped them with copper wire, soldered, then feed them back through the firewall. I can not remember the exact sequence, obviously this has to be done before the fuel tank instalation. I have used this on both Super Steaman, that I have built works just fine.

I had a plane that had the same setup for the elevator and the collects came loose ...it just seems to be a Mickey Mouse[sm=lol.gif] way of doing it. I'll probably use it thought the alternative using 2 servos may be more of a hassle than it’s worth. I going to rap the wires with thread then CA it, then secure the collects it place….should be okay. I just wanted to see if someone had a better idea.
I ‘m using the Sullivan tail wheel 10 to 22 lb assy…I just have to adjust it for the right height.
