Tamiya tt02 servo mount,diy or tamiya?

[twaleta]

Hello all.I recently converted my tt02 to a rally car and it is super fun.But when i was getting ready to drive today,i notices that one side of my servo wasnt bolted in (but it was before).So i unscrewed my servo/mounts and noticed my screw was missing.I put the one screw i had remaining in both holes of the mounts.. And in one of them there were no threads at all!!! (I have noticed for some time that one side the screw just kept on gurning before but thought it was normal)Keep in mind these are the stock plastic mounts.I have a week go get it ready for some racing/bashing with friends.I can either try to make something myself,or order a tamiya mount.Im using a low profile savox servo.Which one is cheaper and would take less time? Also should the new mounts be aluminium?

It sounds like you stripped all four servo screw holes of the stock (kit) servo mount, do I understand correctly?

If that is the case then you would need to replace the mount. A good solution would be to ask here on TC if someone might send you his mounts; a lot of people feel the need to replace the kit mount with an aluminum one and they might part with their plastic one for free to help a fellow TC member.

I do use the stock one on one of my TT-02's and it's been working perfect, but I use machine screws and I rolled thread with a tap.

The Tamiya aluminum one is a big chunk of aluminum and I find it hard to get enthused by it.

Back when the TT-02 came out, people started using the RM-01 mount... It's long since become impossible to find, guess why 😅

Now, to try and help you within the next week, here are some ideas:

1- if you still have one usable hole per side that is more than enough to carry the servo loads. You don't need all four mounting screws.

2- if you are really desperate and must be ready in a few days etc, you can attach the servo directly to the lower deck with double sided tape. Obviously surface preparation is key, but if you clean the lower deck and servo with rubbing alcohol and use the right tape you could actually get a bond so strong that it will be very hard to remove the servo later on! I have done it with only 5mm wide strips of tape and had no problem. I use a thick clear double sided tape made by 3M and available at the Home Depot, assuming you're located in the US

Best of luck!

@twaleta  If the holes holding the servo is stripped then I would just drill through the servo mount and use a machine screw and nut.  If the bottom screw hole is stripped, I would try a larger screw... just to get your car back on the road, and buy an aluminum one as back up.  They don't cost much to start and they can be a pain to make unless you have a drill press and tap.

GL with whatever you decide!

@Pylon80 @Willy iineforgot to clarify it was the holes on the mounts were you screw it into the chassis.Sorry!

Absolutely as Willy says - just try a larger diameter screw for blind holes or a machine screw with a nut for through holes.

So much stuff is thrown away when it can so easily be repaired, or at least made to work, because people are too quick to say it needs replacing...

There’s also the CA glue trick. Fill the hole with CA glue and let it dry. Then you can form new threads as it will cut them into the hardened glue. Very effective on stripped threads in plastic

I recommend aluminium upgrade. Stock mount is almost like rubber.

If you do not want aluminium, just buy sprue with mount or use nuts, as someone above suggested.

Where are you from?

I've gotten away with putting super glue into stripped holes, then using the stock screw.

Alternatively, there is a cheap "Option 1" or "RCRacing" aluminum servo mount. I've tried one of them out and it was fine enough, same basic design as Tamiyas mount but cheaper.

For future reference, always turn the screw in counterclockwise at first, then turn clockwise after you've felt a notch. This helps to prevent cross-threading.

Yeah i guess so... But a solid aluminium one would seem more solid and the force of the servo would be split more.

Yes stock mounts are pretty bad... Aluminium would be good.Im in chicago

Yes the glue trick would work... But one screw that the hole was stripped fell out,and i cant find it.So i would need to buy screws anyway.So i think ill get the alumium one? Would it fit for a low profile savox servo

You could hit your local hardware store and look under metric screws, short 3mm.

The cheap aluminum brands that I mentioned come with machine hex screws and shims.

GPM is my choice for aluminium servo posts. <£4 each.

@twaleta if you choose this route, make sure you have some spacers as you may need to push the servo forwards, just like how you need to flip the stock servo posts for different sized servos.

Thanks.Ordered the tamiya one tho because it came with screws

Yes thanks for the screw length
