5/32" Wire is THICK, or is it?

I needed gear wire and I know I have 1/8 someplace, but all I can find is my 5/32" wire. Used for RC.

I can't believe Stunt guys are using 5/32" wire on their models?

Are they?

I will need two lengths attached to the wings.

56" in span and 36" in length, MVVS .49 for power.

Thanks,

Charles

1/8" is the standard size for wing gear in Stunt Planes , 5/32" is really common for R.C.planes. Keith

18" wire is size used and will take abuse. 5/32 is much more rigit and will break a wing on hard landing. Don't belive me try it.

OK,

I guess I'll dig deaper and find my 1/8" wire.

Thanks for that.

Charles

Most of my control line models use 1/8 inch wire. However 5/32 wire can be used when more strength is needed. The 5/32 gear wire is installed into a steel roll pin which is mounted in the landing gear block.

I've mounted gear in blocks.

What is a "steel roll pin?"

Nice model.

Charles

A pin that is rolled from sheet steel, typically used as an insert or axle that grips after insertion.

I don't understand the point of this steal rolled pin.

Is it used to extend the axle the wheel is on?

Why not just weld a solid piece or make the wire gear again?

Unless the model is built in such a way you cannot get the wire out?

Photo? Another explanation?

Charles

If you have a hard landing or just from alot of use the gear can become loose in the mount as the wire works in the wood. The Roll pin glued into the mount and keeps it from getting loose. The Eclipse gear is mounted at the trailing edge of the wing has a small upward leg and the roll pin was needed. If you have a large hardwood block on the upward leg you may not need it. In the Sig Twister (which has 1/8 inch gear wire) the fuselage mounted gear has a brass tubing to hold the gear. That works fine till a hard landing then the brass tube will be bent. The rollpin works good here as well.

As has been posted 1/8 is normally plenty strong enough. I went to 5/32 on the nose gear of my Latency because 1/8 wasn't strong enough and was bending on a normal grass landing. Also used 5/32 for the main gear on my big FJ4 carrier airplane. The Score ARF comes with a metric size wire that is close to 5/32, I used 5/32 to make longer gear for prop clearance and it worked out well. All of these are special situations that we don't normally run into.

I still don't understand.

You're using rolled sleeves as a shim? And they sit in the grove of the hard wood.

OK, I think I get it.

That keeps the end from wobbling. (sp.)

That rolled pin thing. It seems it just makes the wire thicker. Unless it's glued in place?

My RC models with blocks, I glue in place the correct size brass tube. Then just slip the wire into that. Certainly the longer the tube the better.

Does anyone still use "J" bolts?

Charles

Hi Charles,
You know that part of the wire that goes vertically into the block up in the wing at the end of the Sig gear blocks? This guy glues a roll pin that has it's ID matching the wires OD. That's all.
I use rock maple for mine. Thousands of flights on asphalt with no problems.
My longer 1/8 wire gear is a little flexible, so I laminated hard balsa onto it as a fairing. Helps a lot. 5/32 is fine too, if the gear is real long and flexible with 1/8th.
Chris...

Yes,

Now I get it. One would think the brass insert would be a better option, smaller Diameter hole to drill. Leaves more meat around the wire.

I'm going with the .125 whire. The wire, from the wing to the axle is only 5".

What size prop does a MVVS .49 use? I'm guessing a 10" prop?
