但係又有post話唔得。唔知邊個啱!? RCTECH討論區
The tooth count is the same on both gears. The difference is, the spacing on the outdrives are different. The Gear case of the FF03 is narrower therefor if you were to drop a TA06 Rear Diff in the FF03, it would not fit. If you were to drop an FF03 gear diff in a TA06 gear case, it would slide side to side.
