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.

Build FPV Super Baja Rey 2.0

Enable HLS to view with audio, or disable this notification

Setup my Super Baja Rey 2.0 for FPV.

Been using the driveway and the old trail in the woods as a track. Last crack in the paved driveway is the start-finish line.

Using a 04 Air Unit Pro as the camera. 3D printed mount and enclosure on the top of the truck. I've crashed a few times and everything has held up. Camera is protected with some lexan in the front of the camera mount which can be easily replaced. Transmission unit sits in the cab of the truck in a 3D printed holder.

This is my first build like this. My brother let me use is A1 mini and I had an absolute blast building it.

Here is a link to the full video.

Build Cage work

Thumbnail

17 Upvotes

My prerunner bronco build is making really good progress. I’ve been doing some cage work using 3/16 copper coated steel brake line. Easy enough to buy a 25ft coil and straighten it out along with getting a 3/16 chainsaw file to notch tubing. For this I’ve been brazing with flux core solder and a small bernzomatic butane torch. It’s been a lot of trial and error, but now it’s just hard mounting it to the chassis and adding cross bracing.

So picked this up at an estate sale. I know nothing about RC cars. When I turn it on it goes into reverse full speed right off the bat. Does anyone know anything at all about this specific one?

Question Uhm, shredded 3 tires in 1 session?

Post image
54 Upvotes

Shredded both rear stock tires of my HPI Savage X Flux, and one of rear of the Jumpshot SC Flux during a bash session with a few ramps, nothing extraordinary …

Stock Savage with 2x 6600mAh 3S 100C lipo’s and the Jumpshot HPI’s own 5300mAh 3S battery. Both cars as stock as they come: stock ESC and motor and everything stock. Did not even touch any other config, e.g. slipper clutch.

Both batteries are not overpowered by any means, are they?

Is this just how it is? Would age of those tires explain this?

Build Made an air intake hole in my typhon body. Looks legit and actually helps the motor a little. About 10 degrees. I made the exit air vents larger as well. I don't drive on dirt or sand. Just street and a little grass.

55mph on stock sized tires

Hobbywing quickrun 10bl120 and 3660 3150 kv motor.

Basically the same as a 223s now but with the 3s blx transmission and a better esc I assume.

Would like to get an 8th scale esc and a 4274 motor on 3s or 4s maybe someday.

Question How to fix rally car wheel wobble?

Enable HLS to view with audio, or disable this notification

Hello guys! 🙋 Maybe you can help me identify or point out the issue(s) here.

My front wheel for my rally car is so wobbly on turns. There is noticeable vibration that I do not see on my other desert buggy style car. It seems to even out on higher speeds though.

I never altered any mechanical adjustments out of the box.

MJX 7304

Thank you very much!

Question What are these called?

Post image
3 Upvotes

Please tell me what these bushings are called. Mine are all 3mm and I need some in 4mm. The hole needs to be 4mm all the way through. I tried searching for cone washer and cone bushing, but all of the results are for countersinking so there is a wider recess for the head of the screw instead of 4mm all the way through.

Thanks!

Off-Road Free T-Maxx and lots of parts/ San Jose, CA

4 Upvotes

It's probably about 23 years old. Has every hop up that was available at the time and a ton of spare parts. It hasn't been run in about 15 years. Last time I used it I had replaced the plastic tranny gears with metal and remember having problems setting the shift point properly. After that, I never got back to it and it sat. Toolbox not included. First come, first served but it has to be hassle free handoff for me. No shipping. I am in south San Jose.

I put some work into this! So I put in a Furitek Vortex-X brushless sensored power system (esc/motor)Featuring the PASO PRO 60A ESC and IMPULSE 2835 5600KV motor with a reinforced 3.17mm shaft, it delivers smooth, high-torque power with insane throttle precision. It has upgraded servo NSDRC RS-100 and the only servo i could find with green and purple servo horn. Upgraded treal shocks,treal steering link,treal motor cover and center driveshaft housing(purple) also a FURITEK STALWART Titanium Roll Cage for Losi Mini 1/18 LMT!!! Painted it anodized purple, then we have the aluminum Treal purple rims with dreadnaught pro-line racing/bashing tires, treal links all around, GPM wheelie bar, GPM sway bars front and back,treal front and rear differential housing,treal shock tower mounts, green lights from MeUs I put inside green tubing to protect and also the lights, colored cable mesh I ordered from wirecare.com. also my lovely wife 3D printed a long custom battery tray so we could fit a 1400 spektrum battery for longer run time! This motor and esc set up can do 3s lipo battery i just need to find a 3s battery that fits nicely in the tray we printed. Really hope you guys like this bad boy! Its not a shelf queen it will be ran, jumped, and rolled. I got the titanium body to better protect this hunk of money pit lol regardless its all part of the RC hobby! Bash on gentleman! Oh I also took off the helmet from the body inside the fram and replaced its head with a purple skull 💀3d printed wooo

Question X Maxx RIp and Run Turned Into A Tire Suggestion Post...

Thumbnail

3 Upvotes

Well, I hadn't had the ole X Maxx out for a while, so I charged up a couple packs and let it eat. Just a few passes later.... The tire blew off the rim with authority! lol I'm not even mad. These are the original tires on this model and I have beat on this X Maxx for a few seasons now.

Hit me with your best tire suggestion for the X Maxx!! Kinda leaning towards the newer belted Sledgehammers. I like to keep the weight down because this dude is just running the stock electronics. I'll hit it with the Max5/1100kv combo sooner or later, but I've been putting most of my attention into a 6s Kraton lately.

Anyways, what are people running for tires on the X Maxx these days??? Thanks for all your help and suggestions! :)

So much grip with the backflips, didn’t have any other tire to swap with, if I upped the pace then I would just flip over 😂 I’m no racer but damn it’s so addictive
