AliExpress and Temu referral codes

36 Upvotes

Due to the huge influx of spam posts with AliExpress and Temu referral codes, and the complaints we have received from sub members, anyone posting these on the sub will get temp banned for the first offense if you are already a subreddit member, permabanned for subsequent offenses.

If you are a first-time poster on the sub (meaningful posts, not spam or one word answers), posting these links will get you immediately permabanned.

This is not designed to stop people posting links to AliExpress items in posts in response to questions or recommendations. or the infrequent posts we get of *"is this a good RC car?"* with a link to an AliExpress item (the chances are, at best it's an adequate RC car if it's from AliExpress).

Thanks to our eagle-eyed sub members for bringing this to our attention, and please do continue to report posts that violate the rules.

Off-Road Stopped Mojave Grom 3S heat issues with a dual fan setup + scale covers

Thumbnail

131 Upvotes

The motor/ESC on these little trucks gets ridiculously hot on 3S, so I made a dual 30mm fan duct with swappable scale top grills and built-in LEDs. The sealed compartment is great to keep mud out but it retains heat like crazy. I Did some bench testing and it completely stopped the thermal cutouts. Plus the rear vent glow at dusk looks pretty cool. What do you guys think?

Racing So much fun with a rally car

Drive it through the cones!

So much fun and quite difficult at the same time!

Seems that I managed to setup suspension (it got almost the same as was in stock mode 🤣)

Do you use any cones with your models?

I just bought it and the whole story got more interesting.

Are there any tips on setup shocks / gyro etc for asphalt riding?

Initially I thought the lower - the better but not. It turned out that suspension actually helps with turns.

I've had this about month now and I have to say, it's lived up to the reputation of being tough as nails.

I blew the spoiler off on a speed run a few weeks ago.

7 of the 8 wheel sides have needed to be glued

A couple of days off days ago it ripped the hub right off after multiple 15'+ verticle sends. Good thing it ships with 4 extras

I've had it de-tire itself a few times.

This thing just absorbs beatings.

It's a total blast..

BTW the 15mm spacers just keeps it on its feet a touch more. You can see the rest of the hub still attached..

3 Upvotes

I just rebuilt the diffs on my traxxas rustler 4x4 vxl and I noticed that, when turhing them by hand, they felt slightly notchy. They don't get caught at all and I can't hear anything. It's doesn't feel too bad but i just wanted to check if it's normal. I've treid loosing in the screws and that doesn't fix it. I'm using 50k diff fluid.

Question Rocks got inside my lipo

• Upvotes

I recently got a spectrum 3s lipo and some rocks got kicked inside the battery. It got in thru the gap between the wires and hard shell case. I got them out but idk if I should still use it. It charged fine and everything but I’m paranoid. Do I have to just trash this battery and get a new one?

Question Noob question: can i use a motor as a Servo?

• Upvotes

hi! i am starting my journey with the Rc world!
probably in the worst way possible!
i have a 3D printer, and a old little RC helicopter, and i am trying to turn it in to a car by ripping out all of the elettronic parts and rearranging them in a 3D printed chassis.
i am facing various challenges, but there is only one thing that makes me wonder if i can pull this amazing feat off;
i don't have the slightest idea on how to make the thing steer.
i have been thinking about using the little motor in the back of the helicopter used to make it tilt forward or backward an use it to steer the car, but then i wouldn't be able to turn with any degree of precision, or maybe simply solder a servo in the place where the little motor is currently placed.
is it possible to do any of the two option i mentioned in this post?
or i am completely coocked?
sorry for the many writing error, i am italian!

Something Traxxas obviously. I got it as a gift from my uncle and haven't messed with it. There's random loose wires and bolts missing and all 4 tires have bad ball joints or whatever the RC equivalent is. And some sort of mods going on. idk RC much at all. Just asking what's there, what's missing, anything. so thanks in advance
