Does aluminum-to-metal cause glitching?
 

Does aluminum-to-metal cause glitching? I cut a square piece of aluminum as a brace on this nose wheel. Will that be a problem? Thanks

I hate to be the one to break the NEWS to you but.................Aluminum IS a metal.:D

WILL it cause a problem? It might. Not if you have a 2.4 GHz radio though.

Still trying to find an alternative. I but the brace there because there is so much slop with the supplied plastic brace. ?

RE: Does aluminum-to-metal cause glitching?
 

Could, better to find another solution.

try replacing what you have with this or one similar

from your picture I only see 1 bearing block for the nose gear all the gear except that made speciall for a vk cherokee used two blocks about 1 " apart or they were built into the nylon engine mount and went from the bottom to the top.

RE: Does aluminum-to-metal cause glitching?
 

Since the nose leg mount itself doesn't appear to hold the engine consider using a 2-piece strut mount like one of these.

I don`t know about glitches, but I do know steel and aluminum touching together = corrosion.

RE: Does aluminum-to-metal cause glitching?
 

I wouldn't think that would cause glitching. However, if it becomes that much of a problem, move the back gear just ahead of the leading edge of the wing, and make it a tail dragger.

RE: Does aluminum-to-metal cause glitching?
 

If you don't want to replace the whole thing you could put a piece of 1/8" ply where you have the aluminum. It should last a long time.

Ok. I see the nose gear block. As you see, the nose gear must be way out in front of the firewall. What do I screw a nose gear block to? There is nothing there for that?

RE: Does aluminum-to-metal cause glitching?
 

Why do you have to mount the nose gear that far in front of the firewall for?? You should be able to mount the gear directly to the firewall, with the spring loops about 1/8" or so below the bottom of the fuselage.

Hope this helps

Its an arf T-34. The gear has to be foward.

Which brand it is??

Ken

Hi,

Brand is Hangar 9.

Please tell a newbie thirsting for knowledge what the heck "glitching" is. Thanks.

RE: Does aluminum-to-metal cause glitching?
 

For mbilar7: Glitches are uncommanded control movements, always blamed on the radio but also caused by poorly assembled and/or maintained airplanes - and by nervous thumbs!
For all: Metal to metal contact does NOT cause radio glitches. Think about it - your engine, or motor if you use those, all contain many pieces of metal, all in contact with each other and in constant motion. A spark, unseen but there, if often caused when two pieces of metal touch and separate (make and break), and that will often result in interruption of the received signal.
Even metal linkages on metal throttle arms are troublefree - IF a good tight fit is present between the pin and the arm hole. The problem might arise in the future if vibration causes the arm hole to enlarge and make and break occurs.

We learned of the interference problems in the 50s, with poor receivers etc. The practice was to bond between metal comonents, that is to say connect them electrically with a soldered flex wire.

Bonding is commonplace for main electrical services adjacent to water such as in the kitchen. It does not allow a voltage to develop between comonents (for safety) so no static interference when components are bonded.

I am of the impression that it no longer causes problems with modern R/C gear but I may be wrong!

Gary,
Ok, I went and looked at the manual for that plane. Can I ask what happened to the stock landing gear mount that came with the plane?? Why are you changing out and using an aluminum bracket instead?

As for your original question, no this setup will not cause radio interference. RF signals aren't generated from aluminum metal. The RF signals are generated from ferrous metals (iron) rubbing against each other.

i was told not to use metal geared servos for throttle on my trucks,because its not needed and could cause glitch. i think they said it was from the sound of the metal gears. not sure exactly, but that is what im told.

RE: Does aluminum-to-metal cause glitching?
 

Bull, just a fable. Why on earth would the servo manufacturers make a servo that would cause this problem? Answer - they wouldn't. Find a better advisor.

RE: Does aluminum-to-metal cause glitching?
 

Thanks all. I am not substituting the stock nose gear mount. I installed a back plate of aluminum as the stock plastic mount offers slop in that nose gear. See pic.

So, I will have the metal nose gear, rubbing on the aluminum plate. Why is it companies like Sulivan make the metal control horns but use a plastic lining. This is what everyone at my field offers as evidence you don't put metal to metal.

It's funny all the differing opinions!

RE: Does aluminum-to-metal cause glitching?
 

I've also gone through the manual. I'm just not sure how much the aluminum plate will help with stability. It IS a cheesey mount that they provide IMO.

And I didn't say that I don't believe in the metal-to-metal interference issue, I just said that it is NOT a factor with servo gears.

RE: Does aluminum-to-metal cause glitching?
 

when saying metal-to-metal in reference to causing a glitch it needs to be a ferrous metal to a ferrous metal, non ferrous metals won't cause glitching. servo gears are bronze and aluminum, those are non ferrous metals, the Sullivan clevis is mild steal, as are most metal clevis's, they require the nylon isolation or they'll cause RF interference.

I just confirmed something I tried in the shop a couple days ago. I rubbed a piece of pushrod material against an alumimum engine case and tuned pipe. BOTH caused glitching. [X(]

RE: Does aluminum-to-metal cause glitching?
 

then they are aluminum alloys, not 100% aluminum.
