Re: unnamed drum spinner

I take it Needle Bearings are up to the impacts and RPM then?

Re: unnamed drum spinner

For a drum yes as the impact energy is actually very low. Boner only has around 700J in it when it's going full speed and that's with a 3.8kg drum.

The danger from a drum isn't from a single large impact like a disc but rather a series of smaller hits that keep coming again and again.

Re: unnamed drum spinner

Yeh I've heard before that Boner is only 700J but it must us them very effectively!

Ok that's interesting to know. What sort of RPM does Boner spin at?

[typhoon_driver]

Re: unnamed drum spinner

around the 4000 rpm mark. The reason for the low KE is the relatively small diameter of the drum. If I took the same 4kg and increased the diameter then I could in theory store more energy in the disc than typhoon 2 however the resultant disc would fail on impact from lack of structure.

Re: unnamed drum spinner

Did a bit more work today, I wired and fixed in my led and put in some 25 amp fuses from tecnobots to protect my esc. Tried to screw it onto the base plate but my countersink sucks so the screw heads scape along the floor so need to get a new decent countersink tomorrow hopefully! I can't weigh it to see how it's doing because last time I tried I broke my mums bathroom scales so I no longer have any, what type do most people use to weigh featherweights?

Re: unnamed drum spinner

Also what receiver should I use with the spectrum dx6i transmitter, I know it should failsafe on all channels but I don't know which receiver does that?

spektrum br600

Re: unnamed drum spinner

I think the Giant one only fail safe's on the throttle channel. At least that's what I believe mine is doing.

Re: unnamed drum spinner

The BR600 was purpose built for robots apprently but I'm not sure if they make them anymore

Re: unnamed drum spinner

I thought the br600 worked only for the dx6 not the dx6i or the dx5e

Re: unnamed drum spinner

The BR6000 (not 600, just to save confusion) I believe will work on transmitters DSM and DSM2, but they are not made anymore so better going with one of the other suggestions.

Re: unnamed drum spinner

my giantcod rx failsafes with both a scorpion xl and some cheapy 50a escs

[PJ-27]

Re: unnamed drum spinner

What the cheapy DSM2 one?

I can get it too failsafe on my Sabertooth by adjusting the trims and fooling the start up auto calibration, but not ideal.

Re: unnamed drum spinner

yep, i use the £7 one
