im trying to figure out how many Amps per hour my titan 12t pulls. it has the included spur installed and the truck lasts 20 min. i need to know the formula and the answer to this. note: it is harder than it seems.
PS there will be more math rc questions later on.

What is the size of the battery?
We need actual capacity, not what the label says.Whatever it is I just said... I could be wrong.

Need to know how many mAh it has... so yes, it does matter what battery; we only have one part of the equation: 20 minutes.
Whatever it is I just said... I could be wrong.

we can only work out an average from this because the load is not continuous
Does more $ = More fun?

the batt. is a 8.4 3000 MAH. the truck was lifted off the ground and was at full trottle the whole time. the servo was powered by a second radio and a reciever batt.

The need arises to change mAh to Ah... mAh / 1000 = Ah
To calculate run time of a battery... capacity Ah / Ah draw * 60 = time
Since time and capacity is known, using basic algebra you can solve for the unknown.Whatever it is I just said... I could be wrong.

Discharge amperage for a battery:
mAh > Ah * discharge C = Available Amps
so
(mAh/1000) * discharge C = Available AmpsWhatever it is I just said... I could be wrong.
