Motor Help!!!
 
Where can i find out how many amps a Tekin Redline 10.5 Motor draws???

Don't think you're going to find that posted. Amp draw is a function of too many variables to post a given figure. Only way I'd know is to find someone running your setup or a very similar one thats used a onboard data recorder to see what the setup is drawing.


This'll give you a range in amp draw. I did this with my Slash and a Sidewinder/5700 setup and saw a range of 8amps to 40amps, average of 18amps with spikes as high as 114amps.

I have a math equation that will tell a person what lipo to use but i have to know amp draw of motor in question....

This is starting to sound like a homework question...

Amps = Power (watts) / Volts...

Novak lists there 10.5 as a 235 watt motor...
235w/8.4v = roughly 28 amps...
HOWEVER, as stated before, there is a lot of load variables that will likely make it much less or more than that.

You'll need a load constant to base the amperage off of.

As far as a LiPo calculator... Data logging helps a lot, & the rules of thumb come into play.
On my 1/8th Scale, a 150amp pack is a good starting point (5000mAh x 30c).
1/10th scale a 60-100 amp pack is sufficient (3000mAh x 25-30c).

Any more "punch" is a personal preference.

well i found a deal on Tekin 3400 23c packs, these will be fine for my 10.5 on a short dirt oval right???:weird:
