Default ON-resistance

Looking at the new Quantum competition 2 it shows a "typical voltage drop @ 20amps as .013v. Is this comparable to the on-resistance #'s thats advertised for other speedo's? The original quantum comp shows .00045 and novak gt7 .00058. I think those #'s are ohms.

Use Ohms law; U=R*I, that is, voltage=resistance*amps.

The original quantum comp: 0,00045 * 20 amps = 0,009 volt.

The other way around: The new quantum: 0,013 / 20amps = 0,00065 ohms.

Maybe we've found the reason for LRP to change their way of spec'ing an ESC

Personal I find we're talking about minor marginals, but it might of course depend on the level of competition. But it's nice to see that my 7.1 still can compete: 0,00052 ohms.

Default thanks

Thanks for the info. I'm still happy with my novakC2@0.00049.

So true. Once you get a good speedo, you can have a lot of fun and races for years, without having to upgrade.
