a thread for the odd question i may have.
First has the name atom been taken?
Also anyone tried these speedo's ive linked their rated at 16v max and have you ever overvolted them?

[plargen]

i use them in night fury and scruffy but there are a few software versions on ebay so only some work properly

[ady]

Ok. i was gonna try some as a punt as they were cheap. I have a scorpian in another robot so will use that.
I am replacing a motor on my k9 but i need some reverse screws for the drills can these be bought anywhere seperately.

[plargen]

unfortunately the supplier i got mine from seems to have stop selling them each esc will happily run 2 drills on 4s and barely get warm after 3 min

They kept coming loose on k9 so i threadlocked them. Think i overdone it with the threadlock and ruined the screw getting wheel off lol. My spare motor also seems to be missing the screw i think their m5 or m6 reverse thread.

I had a set of those ESCs in Hardwired 1 and they had a brake function on, but happily took 2 drills each. They did also eat themselves after I put them in my beetle. They work fine in Scruffy/Night Fury from what I've seen but it's all really dependant on you getting the right ones which as far as I can tell is pure chance unfortunately...

thanks for comments i think i will pass on them and just share my scorpian between this fw and k9, not a problem.

Ok. I need to bend some 8mm thick strips of hdpe about 2" wide. I have a heat gun for paint stripping is that a good method? Or put it in the oven? Wondered what others have done and will it hold its shape once cooled.

[maddox10]

I use a combination of L angle and a dedicated (Leister) plastic bending/welding heatgun.
Or for smaller bits up to 110mm wide, I take up my bender, and go with the heatgun again.

Ady if you're still after reverse thread screws I have a couple spare you can have, m5 ones.

[ady]

Yes please sam!!

Quick question, when building a chassis out of hdpe, should I use threaded inserts on all joins? Including inner bulkheads and floor, or do some people use wood screws in places. To go into a full combat event

[RogueTwoRobots]

Neither ideally. The screws will wear down over time and the threaded inserts pull out. Barrel nuts and bolts are the way to go for HDPE.

[ady]

Ok thanks for advice

[overkill]

For places where barrel nuts won't fit, you can use Tee nuts:



They are a type of nut insert that is pressed in from the far side of the HDPE and will not pull out. I have used them for years without problems.
