I do not understand this.
(sorry, i do not speak english very well)
I tried a 3400mah (no hard case) lipo pack in one of my 1/12th scale cars.
It is 2S , 7,4V, and has about the same footprint as a 4cell Subc pack. In fact it has the same length , but it is a bit taller, and also a bit narrower. In any "non- t-bar" type of car it fits perfectly, maybe you have to put the center shock 5 mm higher but...
The motor i used was a 27turn, 5 degrees timing .Nothing wild here, and still the car was really fast , weighed less than 700 grams, and the runtime was superior to 15 minutes, easily. Any more runtime would be quite pointless since the best odourless traction compound i ever tried hardly lasts for 10 minutes.
So my question is : what is the point in going to 1 LIPO cell when all our electronics can't handle it (some speedos don't even turn on when plugged to 3 subC cells, let alone servos ,PTs, etc), and are designed to handle 7,4V?
why would i put a 7x1 motor with 3, 7 V in my car, when my car is already too fast for me
with a 27X1 and 7, 4 V, and already has too much runtime ?
let's just get rid of Tbars !
