What sort of timing do the PP 540s 2700kv run? and amps should they pull with no load? I have a PP 540s 2700kv I put in my toyzuki v2 it made alot of high pitch electrical squeal more than ususal and got hot fast. I just bought my self a motor analyzer for racing and tested the PP 540s 2700kv Here is what it tested at: kv=3159 voltage=7.4v rpm=23377 amps=9.5 average timing was 48dg ph.A= 51 ph.B= 46 ph.C= 48 To me this seems like too much amps with no load, I would think that it should be more around 6amps no load and the sensors seem to be out alot |

Throttle curve doesn't affect power or torque, just how the throttle is delivered. A nice gentle exponential slope gives better low speed control without sacrificing higher speeds. Quote:

What could be the cause of a stuttering sensored brushless motor? Example: A Trailmaster BLE Pro and Puller Pro 2700 kv combo that has always been run with it it's limits, never overheated, running stock gearing on 3S, who's connections have all been confirmed to be good, stutters when throttle is applied. The stuttering is accompanied by a high-pitched sound. This is all Hypothetical, of course. |

Hi John, Mamba Monster X + Puller Pro (Standard) 3500Kv 1. Will this combo work well on 4S? 2. Would I need to gear down to keep temps at bay? 3. What would be the performance difference vs a Castle 1415 2400Kv motor? For use on a heavyish Wraith for crawling and bashing Thanks Sent from my SM-G950F using Tapatalk |

Stock gearing is fine The puller will have far better startup , more speed, more power, and generally be a better motor for your wraith. | ||

Mamba X will be perfectly fine in your rig. MX is meant for 1/10th scale and MMX is 1/8th scale. You can take castles rated weights with a grain of salt. There Micro X is only 'rated' for a few pounds yet there going in scx and wraith without issues. Crawling is less taxing then racing so you can get away with it.

Don't get me wrong, I run the mamba x in all my vehicles, but they are all as light as possible and under 8 lbs. What kind of rig is this 11 lb monster? Sent from my SM-N920V using Tapatalk | |

The micro X is more than enough for most crawlers. I've seen 15lb trucks run a microX without issue.
