Griffin: So, it's not just a pure kv factor, it matters how many rotor/stator poles a given motor has as well. Hmm. I was hoping for something like "min rpm for proper ESC operation is motor kv/10", or something along those lines. I really don't feel like adding a couple more specs to each of the motors in my list.
Most of the time, manufacturers don't supply the stator and rotor pole count. Is there a way to get this information manually simply by turning the motor shaft and counting the magnetic "detents" during one full rotation? For example; a Feigao/Wanderer/Nemesis is a two-pole and has two magentic detents per shaft rotation. A Neu is a 4 pole motor, but has 12 magnetic detents per rotation.
macrow: ballooning depends a lot on the tire and the foams used inside. For a tire to balloon out, the sidewalls have to contract and good/harder foams will help limit this. 1" ballooning on a 4.25" tire is a 23.5% increase in tire size! That would make the tires look like pizza cutters and would seriously hamper handling. The calc only show theoretical speed, ot theoretical
controllable speed.
