First a simple lesson in Ohms Law
Power (in Watts) = Voltage x Amps - a directly linear relationship
We all know a motor delivers a certain wattage (power)
if the voltage goes down the amperage must go up.
So I was running a Prince 25" mono with an Ammo 30-50 2300kv
on 3s - yielding a free running prop speed of 25530 RPM
First run on a 435 was a dog (GPS 32 MPH)
Running 3s2p 30c total 10,000 mah
Got wild and put a 437/3 made it 1/2 lap and the Hacker Navy 77 went poof.
The drive is a very free running system with no binding.
Figure it pulled more amperage than the Navy could handle.
See Ohms law above.
Mean Machine - suppo 200A modified - Aveox 1421/1.5Y
4s1p 3600 mah ran a x442 to a rousing 34 Mph.
Driveline spins with no binding.
Went with a X445 made it one half lap and the suppo went
"I will go no mo senor"
Will not arm or make any motor chiming
Replace suppo with a turnigy 100a HV
Ran 5s [a 3s and a 2s (same c rating) in series]
made it 10 FEET and major smoke - dead short in the ESC
even burned a cell open in the brand new Turnigy 3s lipo
Battery now shows 0 voltage.
I hate that smell!!
Went to fire up my favorite Delta Force Vortex.
Has been running just great
on 3s with a suppo 125a turning an Ammo 36-56
Now
It will not arm and run unless I feed it 5s - less voltage it will arm
but will not turn the motor.
Some days your the windshield and some days your the bug.
I feel like a SPLAT.
Sorry for the rant, but I'll have a better day tomorrow..
I hope.
