aerobird throttle problems

[xt600]

When flying my aerobird callenger in cold weather I was having trouble with the throttle cutting out on me when I would adjust my motor speed.
I then got this bright idea that a shot of tv tuner, cleaner and lube into the throttle control of my radio would smooth things out, afterall it always worked great on that scratchy volume control.
What a mistake, it was like I dumped sand into it, it had kind of a gritty feeling to it when I moved the control.
I cleaned the lube out the best I could and added a little silicone grease,but it's still not right.
Does anybody know how I can repair this or is it new radio time?

dismantle it and try to clean it better. try using denatured alcohol as it won't harm the electrics and might break down the lube you used.

Cold weather is causing the batteries to dump earlier. go with a larger Mah battery or try to use them Hot off the charger.

Thanks for the advice,I will give the alcohol a try.
I know the batteries are not the problem,as this can occur immediately after I install a fresh pack,when I retreive my downed plane,mess with the throttle and get the motor running,I can continue flying for several minutes or until I make another throttle adjustment.I have two aerobirds and never had this problem with my other plane.

After 300+ flights you can imagine that I have come across various things that
need to be fixed on my Aerobird. I fly it in the snow, the wind, the cold, I
fly it anytime and everywhere. My Aerobird is not babied.

On a couple of occasions I have gotten the interior quite wet. This lead to
some erratic motor control or problems with servo control. However when I let
it dry out, all was well. But not this time.

Two weekends in a row I flew it over snow. On landing, I got snow in the bird
which got all the electronics wet. Sure enough things didn't work right. So
I packed it up and took it home to dry out. But this time the problem did not
clear up. I was getting a pulsing of the motor above half throttle. What do
I do?

Since drying out did not help, I concluded that something had been left on the
circuit board that had been on the snow and it was causing a short. So I took
some electrical contact cleaner. In my case I used TechSpray RID-OX contact
protector/enhancer.

I sprayed the circuit board, still in the plane, especially the X port area.
Then I let it dry about 20 minutes. Problem gone.

About 2 months ago I had a similar problem with my transmitter. I was
occasionally getting full throttle even though I had the control all the way
to zero. I opened the radio and checked everything. Nothing obvious. So I
sprayed the throttle control with the Rid-0x. Let it dry overnight. Next
day, problem gone.

Net net, if you use your plane as freely as I do, you are going to get some
dirt someplace where you don't want it. If you see a problem like this, pick
up some contact cleaner, like Rid-Ox, and try cleaning the circuit board. If
your plane is not working right, it is worth a try.

Clear skis and safe flying!

================================================== ==
I also used it on my Zagi

This product was recommended by the local electronics store for this purpose.
Cleans and seals to protect from moisture and corrosion. He encouraged me to
use it freely.

On advice of a friend, I originally bought it to use on my ZAGI electronics.
Since we fly near the ocean, before I sealed in the electronics, he had me
fully assemble the receiver connections, then put it in a plastic bag. Then
spray the receiver and connection area of the receiver with this to reduce
chances of corrosion from salt air sneaking in.

A few months ago, I dropped that zagi in the ocean water about 2 feet from the
shore line where It was washed over by waves for a few minutes till I could
get to it.

I opened it up a flushed everything with water several times at the beach and
when I got home. I pulled everything out and let it air dry after one more
washing. After a week the micro 555 receiver range checked fine and after
inspecting al the interior components of the receiver I saw no signs of
corrosion. It was all fine EXCEPT the receiver battery and the plane locator,
both of which had to be replaced and neither of which had been sprayed.
EVERYTHING GOT A LIBERAL SHOT ON THE REASSEMBLY. So far so good.

I will keep my eyes open for any sign of problems and will post if I do see
any problems. However after about a year on the Zagi and three months on the
Aerobird transmitter all is working fine.

I will put the Aerobird at risk and fly it where I would not dare to fly
anything else because it will take so much abuse, put up with so much and, if
fatally damaged, $45 and I have a brand new fuselage and a full complement of
electronics, ready to live the free flying life again.

My HItec Micro 555 and Electron 6 receivers cost more than that.

Yes, my Aerobird is taken everywhere. That is its role in my fleet and it
fulfills that role well. Parkflyer, thermal glider, slope soarer. :)
