Id just cut the temp sensor lead (or remove it from the JST connector), I rarely run them.

ZachTetra · July 11, 2019, 5:32pm

How do you find the motor beta value for the temp sensors?

RAZerBlade · July 11, 2019, 6:45pm

Thanks @b264… Very detailed answer.

You mentioned I should go with 140kv if I run sensored and with big wheels. Could you explain that for me as I would think bigger wheels would require bigger Kv?

Thank you very much, very appreciated

Flasher · July 11, 2019, 6:49pm

@RAZerBlade Bigger wheels will need more torque to move at the same speeds. Less kv=more torque

RAZerBlade · July 11, 2019, 6:58pm

Thank you @Flasher! I will need to read more about KV and it´s effect on performance. Will go through the search function and come back in some days. (if anyone has a great link on that topic would highly appreciate that).

Best regards

If you haven’t, maybe start here?

There’s a section about kv ratings

So I bought these cheap velcro cinch straps to hold my enclosure temporarily and a couple of the loops have broken already from riding. I JB welded one of the broken loops already and will test it later to see if it worked or not.

@b264 you’re the JB weld guy - do you think putting a coating of JB weld on the loops as reinforcement would be a good idea to prevent any more of them from breaking?

Skunk · July 11, 2019, 10:24pm

Just replace the plastic loops with good zip ties lol.
Likely the jb weld will hold and it will just brake where the jbweld ends.

whaddys · July 11, 2019, 10:26pm

OMG zip ties that’s a good idea. I’m gonna rename this fucker Zipper cause it’s made out of zipties

b264 · July 11, 2019, 10:31pm

JB Weld is more like concrete, it’s great under compression but not as good under tension. If you used zip-ties as suggested above it’d be better I think

ZachTetra · July 11, 2019, 10:33pm

If you REALLY need it to hold, you can get U-bolts at Home Depot for a buck each. I use them for broken tow straps occasionally

whaddys · July 11, 2019, 10:33pm

just curious - what types of adhesive work well against tensile forces?

b264 · July 11, 2019, 10:35pm

Not sure but sometimes I put JB Weld on cloth or string or other things

Steel and bolts are great for tensile, @ZachTetra’s idea is gold

ZachTetra · July 11, 2019, 10:37pm

This is probably the best, hella cheap and low profile. Once its secure you can just dab some loctite on the threads so it stays forever

I’m a little slow sometimes; I’m not sure I’m seeing how to implement these on the plastic loops? wouldn’t I need to effectively replace the entire loop with two of those u-bolts with something connecting them on the top and bottom to make an entirely new metal loop?

ZachTetra · July 11, 2019, 10:41pm

Anywhere you see a plastic loop, cut it and put a metal chain connector in its place. They have the same size and shape, but easily 100x the strength

Edit: its just a 1 to 1 replacement, go to your hardware store and look for something similar that has the same interior length (long straight sections) as the width of the strap

whaddys · July 11, 2019, 10:45pm

cool, I’ve got some ideas now on how to make a new loop, thanks!

ZachTetra · July 11, 2019, 11:38pm

How do you record gifs you can upload?

Skunk · July 11, 2019, 11:42pm

I assume there’s an app for that

wafflejock · July 11, 2019, 11:51pm

I just got a pixel 3A and it has a “motion photo” option in the camera app that captures some frames and can save/export that out as a gif. Imagine there are also apps to do the conversion though.
