Bon, j'ai bien essayé de me débrouiller tout seul, Mais là... Je cale
Comme dit dans le titre, je voudrais passer mon Mini-Quake en Brushless à un cout très très réduit
. J'ai pour le moment cherché le moteur, mais y'a tellement de choix sur la bay, que je n'y comprends plus rien 
Pour rappel: le mIni-Quake est un petit MT 4x4 ech:1/18 pesant environ 1.2Kg motorisé d'origine par un moteur taille 380 (axe Ø2.3mm).
-Pour les Kv (trs/V/mn) je pense qu'il faut taper dans les 5000 ? Je me trompe ou pas ?
-Pour la tension admissible, faut tabler sur un moteur acceptant jusqu'à 18-20V ? Je me trompe ou pas ?
-Hormis les Kv et la tension, y'a surement une question de puissance, de nombre de tours (de bobines), d'ampérage, de résistance, sensorless ou pas... et c'est là que je plante
-Après J'ai vu du Outrunner... du Inrunner ... c'est koi la différence, quel est le mieux ?
Voici qlqs moteur sur lesquels je me suis arrété, VOUS les pro du BL, donnez moi vos avis, merci

Il y a beaucoup de moteur non destiné aux voitures, mais ça devrait être qd-mm compatible ? non?
Pour le choix du Controleur, faut il obligatoirement une carte de programmation ?
J'ai trouvé ça:

35G Programmable Brushless Car ESC 60AContinue 80A burst with BEC x1
(1)Features:
This device is designed for Non-Hall (sensor less) BLDC (brushless direct current) motor especially
for RC car with all necessary protection including low voltage, throttle signal losing and over heat with
self-check. function Intelligent starting output character, linear throttle curve and supporting high speed
(up to 240,000 RPM with 2 poles, 40,000RPM with 12 poles) will make controlling more attractive
and interesting.
With program card adopting LCD panel, all parameter and option can be easy configured
accurately. More parameter and option, such as model type, start output power, middle range of
throttle, brake mode and etc. can be chose according to modeler requirements.
Fast direction switching (<0.5s without load) can help to operate complex activity.
Can apply to aircraft model also.
(2)Specification
· Input voltage: 5.5V -21V (support 2-4 lithium batteries)
· Continue current: 60A
· Burst current: 80A (within 10 seconds)
· Max speed : 240,000 (2 poles), 40,000 (12 poles).
· BEC output: 3A/5V
· dimension:( length x width X high): 58x27x28 mm
· Weight: 35g
(3)Parameter
1?Low voltage threshold: user can set proper voltage threshold according to cell quantity in
range of 00.0-49.9V, the default is 5.5V.
2?Brake: Off, soft brake and hard brake. Default is off. Soft brake works like an ABS system,
hard brake means keep breaking till stop.
3?Timing: low middle and high, default is middle.
4?Startup mode: fast, soft and ultra soft. Fast apply to low inductance and start-load motor,
ultra soft apply to high inductance and start-load motor. Soft applies to case between above two.
5?Protection function: reduce power or cut off for selecting, default is reduce power. In reduce
mode when over heat or low voltage occurs, output power will reduce to lower than 50%.
6?PWM frequency: 13KHz and 8KHz, default is 8KHz. 13KHz is an option for low inductance
motor.
7?Throttle mid range: 0-29%, default is 5%. This setting applies to car mode to configure loose
range of throttle range.
8?Governor speed: To set the constant speed for RC helicopter.
9?Start power: to set the ratio of output power when starting in range of 00% - 49%, default is
00%. Under default setting, output power is decided atomically by system according to throttle
stick position.
10?Model type: airplane mode and car mode.
11? Forwards and backwards scale: to set the throttle scale of forwards and backwards. Default
is 50%:50%.
12?Direction type: Mono-direction, Bi-direction and conditional Bi-direction. This setting is not
??available in airplane mode.
Note : The detailed explanation see "ESC for RC Car."
