1/10 Truggy 用 540 or 550 (有感/冇感) Motor 好 (新手問題)

買咗架4WD Truggy ，用540 (同幾多Turn) 摩打好，定係550摩打好。而Lipo電又用2s定3s/4s，15/16 唔知點選。我諗定咗摩打同Lipo，ESC就大概知用邊隻。
玩法: 大概都是在球場或草地亂飛，多謝回答。

How heavy is your truggy?
If it is ~ 1.5 to 2 lbs, then 540 motor is enough
If it is > 2lbs, then 550 motor is better.

Also,540 motor and 550 motor shaft are different size. 540 usually is ~ 3mm while 550 motor is ~ 5mm.  This depends on what pitch size you need for your car's spur gear. (ie 48 dpi or mod 1)

你買左邊款車?

It's OFNA Hyper 10TT and its weight (full load) is about 2KG. I guess 550 type is more suitable.
Another question is 3s or 4s?
Thanks C hing.

550 motor is always more suitable for heavier cars because they can give you more torque.
If 2S, choose a motor in the 4000kv range
If 3S, choose a motor in the 3000kv range
If 4S, choose a motor in the 2000kv range

In general, it is better to run higher cell with a lower kv motor.  this way, all electronics will be cooler.

It's very clear. Thanks C Hing
