Gluing tyres???

Another introduction to me was how much thought & engineering goes into the tyres (tires) for scaled RCs. There's a whole universe of tyres with different compounds, tread patterns, foam-filled, etc. If you're into racing you can buy slicks, for off-road use, get bead-lock rims with mud-terrain tyres - unlimited choice.

The regular (non bead-locked) tyres are usually glued onto the rims, so they don't come off when you RC is in use.

The mighty little Teton comes with it's own set of mounted wheels. You can buy the entire set [Traxxas Part #7672], just the wheels [Traxxas Part #7671], or just the tires [Traxxas Part #7670] if you want replacement parts. They come in sets of 2, or just buy replacements from another manufacturer.

My tires & wheels are in fairly good condition but over time the glue came loose, and one or the other tyre keeps popping off when we drive the thing around on our little off-road patches.
As I already had everything apart whilst fixing the steering servo, now was a good time to glue them back on.

Traxxas, or many other manufacturer will gladly sell you tire glue [Traxxas Part #6468] but a little bit of browsing forums seems to advise that it's pretty much the same / similar to cyanoacrylate fast-acting adhesives (yes, Wikipedia ), what we commonly refer to as Super Glue / Krazy Glue, etc.

You'll need a 3/32" or 2.5mm hex head bit to remove the screw that holds the wheels to the hubs:

These tyres are malleable, so you can pull them off without a struggle:
The Radio / Remote Control Cars Thread. (RC)-02.-20200419_123439-edited.jpg

Apply a thin layer of cryanoacrylate adhesive () into both inner & outer grooves that hold the tyre. Flatten any blobs with an object that fits in the grooves, e.g. toothpick, matchstick, agarbatti (incense) stick end, etc.
Mount the tyre before the glue dries and wait for a few minutes before it sets:

After fixing the issues, we were elated & went a little bit wild:


This, & a little jump off a small concrete block unfortunately resulted in a broken suspension arm:

Needless to say, replacement parts are available [Traxxas Part #7630] but the replacement parts are also plastic and as this is now an older model, they're getting difficult to find. So I am looking for some aluminium (sturdier) replacements.
I'll put a write-up when I have them in hand...

Default Suspension Arms

Suspension Arms.

As mentioned in my previous post, after getting a little overzealous in our running of the RC with our upgraded servo, we ended up breaking off one of the suspension arms.

Now, I wanted to get aluminium arms but reading a bit into it, I learned that plastic arms provide a bit more flex and are recommended by hobbyists. So decided to stick with plastic.
That's when I came across: RPM R/C Products.

They make tougher high quality injection molded replacement parts at a great price - that's what I was looking for [RPM R/C Products Part #70862].
(They cost a wee bit more than the Traxxas replacement parts but they're heavy duty & seem solid):

Begin disassembling.

Remove the camber & toe links from the wheels. A long-nose pliers will help & you can use a bit of force on them. If you break any you can of-course get replacements [Traxxas Part #7636].
Pull the shock absorber off the lower ball mount. Later on you'll also remove the ball mount & transfer it to the new arms:
The Radio / Remote Control Cars Thread. (RC)-05.-20200427_203808-edited.jpg

Unscrew 6 screws to remove the bumper:
The Radio / Remote Control Cars Thread. (RC)-06.-20200427_205635_205825-edited.jpg

Removing the small screw uncovers a steel pin that holds the arm onto the wheel.
Some times these pins will slide out with little pressure from a paper clip.
Remember to take the ball joints out using a 3/16" or 5mm hex head bit:
The Radio / Remote Control Cars Thread. (RC)-07a.-20200427_205021_205050_205302-edited.jpg

Other times the pins are stubborn & you'll need to hammer them out with a nail & hammer:

Disassembled:

Comparison:
The Radio / Remote Control Cars Thread. (RC)-09.-20200429_172110_173524-edited.jpg

Put in your nice new suspension arms.

Just a couple of shots to show how the pins hold the wheel to the arms, & the arms to the chassis:

The Radio / Remote Control Cars Thread. (RC)-10c.-20200429_174045_174318-edited.jpg

Putting the bumper back on is not difficult but look out for the 2 tiny parts (they tend to fall out):

All back together:

Just a couple of pictures that I had showing a small disassembled portion of the car:

Now you're ready to go out & break something else!

Got a Thunder Tiger S50! It's 1/8 scale 4WD monster truck with 2 auto gears and one of most biggest & powerful 8.6 cc Nitro engines in this scale. Getting spares in India for this is difficult now and they are procured from Ebay.uk

This was my first RC car. It was a monster. I did quite a bit of work on it. But eventually moved to racing and the MTs are not really designed for that. I have still have some arms in my boxes. The arms will break on impact. Get a set or two. Another issue is the fuel priming bulb. Get rid of it.

Try looking up associated Sledgehammer. Its the same car.

Hi Team, require your help finding a battery for my old RC Car.

I recently found my old toyish RC Car which was lying in the storage room. It is a RadioShack Desperado and it doesn't hold a candle to the amazing stuff on this thread. However, for nostaliga sake, I was trying to get it back to life.

The issue is that it uses a 9.6v ni-mh battery which I am unable to find online. It can also be powered by 8 AA batteries however the same would require a battery holder. The battery holders that I have seen online do not seem to come with the adapter which can fit in the RC Car.

Request your help to guide me where I can find something which would bring it back to life.

Attaching some photos of the RC Car and the original battery and charger for reference.

Best,
Enigmatic
