Teething issues

Re: Teething issues

It's all running fine now, got two Argos motors each side at 16.8v running in parallel from each speedo. Wiring is fine (not amazing but adequate), both sets of power wires from the speedos go into a connector block with a deans connector to the battery. This is testing set up anyway, gotta add the power switch and LED. Just think it was one of those things! One thing I may do is put some rubber washers in the speedo mountings to isolate from vibrations. I've now set the electronize's to highest frequency setting and 125% speed and all seems fine

Re: Teething issues

Gone for 4 electronize 30amps now for 4 24v drill motors. Has anyone got any tips about setting them up? The older two are fine but the newer two like to suddenly throw on the brake every now and then. One especially doesn't like going in reverse at all and throws the brake on every second or so when at full throttle. Any tips? All of the speedos have been set at 125% throttle with the highest possible frequency. It's almost as if the new speedos are bouncing of the rev limiter?!
Thanks

Re: Teething issues

Just a check ..you have just the ONE BEC connected?

[Danjr1]

Re: Teething issues

correct. 1 parkBEC connected to the connector block where the speedos get their power from. It would seem that the problem only occurs to the two newer speedos when they are running in the same direction. Im thinking its something with the speedos because they run fine in the other direction? unless someone knows any better?

Re: Teething issues

Just out of intrest, what would happen if you had more then one BEC connected?

[Danjr1]

Re: Teething issues

Not a lot really. Before, I had 4 BECs running and it didn't seem to do anything? Suppose you run the risk of blowing something

Re: Teething issues

Is it possible that the BEC circuit I'm using is underpowered for the 4 speedos?

This is what I'm using at the moment:

Re: Teething issues

I would suggest not, the BEC is only powering your receiver not the ESC's

[Danjr1]

Re: Teething issues

is it powering the relays though in the ESCs? if so, its only pumping out 5v at 1.25amps i think. divide that up and each ESC would only be getting 5v at 0.31amps?!

Re: Teething issues

Its not no, as far as i'm aware its just a signal. The batteries are connected to the ESC to supply them and the motors with power.

Re: Teething issues

Hmmmm ok, looks like I'll be back on the phone to them in the morning! Thanks for your help!

heres a video of the problems. any help?

Re: Teething issues

I suppose you could try swapping one of the misbehaving ESC's for one that is working fine and that will tell you if its the motor or the ESC thats problematic? Only other things I can think of is things like making sure the wires are in proper contact etc and that vibration isn't causing any problems with any of the connectors. If your 2 ESC's that are misbehaving have any shared connectors that the front ESC's aren't connected to I would be inclined to start there.

Re: Teething issues

defo the speedos! just tried

Re: Teething issues

sent both off for servicing so we'll see what becomes of them
