SP17.5T麽打，好盈V3 120a電變，Futaba Gyro,齒比4.16,這组合可以嗎？有甚麽要注意，請指点一下。

齒比4.16，即係幾多摩打齒、幾多大齒？

齿比大了點，三點零到三點三都可以了

大齒用93，摩打由25至31，試到自己覺得架車有速度，自己可以控制到就OK！

真係要用到120A電變?

唔用120A可轉用什麼??

Depends on
a) if use ESC Boost and/or Turbo.
b) if you have good motor heatsink and/or fan

a) if No Boost/Turbo, 17.5 with 4.16 will be very slow (slower than white pig 540)
If use Boost/Turbo, then FDR really depends on ESC setting.  Usually around FDR 2.8 - 3.5, and 3.3. is a good starting point.  

b) And if use lower FDR like <3, need very good heatsink/Fan or motor get hot fast ; and the car be very fast.  
(of course, depends on ability, tires and car setup)

If use Boost/Turbo, ask friends at track side for nominal settings.  
Watch your motor temperature all the time after each run to see if your boost/turbo is too aggressive for track+weather condition.

Everyone is different.
