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)作者: AltezzaMak 時間: 2012-3-15 21:18
你買左邊款車?作者: pma 時間: 2012-3-16 00:24 本帖最後由 pma 於 2012-3-16 09:59 編輯
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?

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.作者: pma 時間: 2012-3-16 16:24
It's very clear. Thanks C Hing
