I haven't had these problems with mine. Did you torque the crank bolt to 40NM? Also apply grease to the pedal thread?
Could be that the manufacturing tolerances are out with your set?

I used grease and a torque wrench, but the threads felt extremely tight.. I'm not entirely sure if the 40Nm reading was accurate or if the wrench clicked too early just from the thread friction.

Maybe I could try using a bit of threadlocker instead? ???

Something doesn't sound right. I did 2 x 5hr ~150km rides on mine including some rought road and they are still tight as.
Maybe get someone to check it out, a fresh set of eyes is sometimes helpful, or perhaps there is a manufacturing issue.

My feeling with a lot of chinese cranksets is there can be manufacturing variations affecting quality and fitment so that can cause problems despite proper installation. Good thing is Aliexpress has a good return/refund policy.
I bought another set recently and there is something different about this other set but I will update soon.
Did another ~6 hour 150km ride with 2000m elevation on my original HUD crankset and still going strong without issues or needing to be tightened.

that's very common due discontinuity in production and poor quality control procedures

Hi there. I’ve had issues with lateral wobble in the chainring whenever I install the crankset; I’m not sure if anyone else has experienced this. I’ve tried everything—placing spacers here and there, using a different power meter, swapping chainrings—but nothing works. The problem goes away when I install Dura-Ace cranks, so I gather the issue lies in the alignment of the crank arm with the spindle, though I’m not certain—which is why I’m asking if anyone else has run into this. I’m thinking about buying a different crankset and reusing my current chainrings and power meter. The options are: Budget: Rpantahy High-end: Cybrei or Elilee

I've noticed there are two versions of this crankset. I returned one set due to the chainrings/spider being out of alignment. It is a problem with the mounting face. However, I've heard it can be a common problem with many chinese cranksets. I bought another set and it is still not perfect but much better and acceptable.

This is the two different types. IMO the model with the deeper spline works a bit better.

What's a good USD price for the 280g version? Cheers

I purchased two sets so far from this store:
https://www.aliexpress.com/item/1005011776046372.html
I think price pretty good and quality ok. First set was perfect, second set slight run-out on one side (<1mm on 50t chain ring edge) but passable.
I purchased another set from another shop but sent back for refund as run-out was maybe 1mm or more and short spline type.

I have 3 sets of the slightly heavier carbon cranks and all have been fine with xcadey and pp5 powermeters.

I’m thinking about buying a new crankset to fix the wobble issue I have with my chainrings. I think a smaller chainring wouldn't make the wobble as noticeable, but since I'm running a 55-tooth ring, the oscillation at the edge is huge; the chain slips off the teeth when I put down a lot of power, so I'm worried about having an accident. I’ve been looking at other chainrings—Elilee and Cybrei are the easy choices, but they’re a bit out of my budget. The other two options are Rpantahi and—the one that appeals to me most, even if it weighs a little more—Leese cranks. I’m not sure if anyone has experience with any other carbon cranksets they could recommend; I’m looking to spend around 200 euros.

the effective weight of 167.5mm version with all the hardware is 308g.
The 280g is only the 2 arms with shaft, so the 280g weight is "fake".
I payed mine +- 320€ with all the unexpected duties included (36€)

I had a similar problem with my coree cranks combined with a leoseek spider powermeter, i turned out that there were not enogh clearance and the crankarm bent/deformed  the spider when torqued down. I managed to fix i by placing a thin spacer (0.5 mm) between the spider and the crankarm.
