MMM 2200kv Combo ships....

[XSKAPE]

Got an Email from castle. They are waiting on the motors. Should be in stock a week or 2. So i believe they will ship then :-)

PS. 21/51 pinon/spur on 4s and 1/8 diffs will do fine on an E-maxx? what about 5s?

This is great news. I can finally retire my Feigao and throw away my temperature reader. I think you can only get the motors in the MMM combos though. Hopefully there will be some nice Christmas specials on those.

21/51 would be nice speed (43 mph), but i think 51 Spur is too little and the motor could hit the transmission (maybe in the High GC holes), and where did you find a 51T Revo Spur?

You'll be okay. I'm running 51/20 on my gmaxx using a strobe slipper setup with UE 8 spider gears.

[Smashwings]

ok, so no problem then, I was thinking about an E-Revo and the E-Revo transmission that have problems with low Spur gears.

Maybe you may add a little tire balloning to the calculator, if you tape the tires there's a little balloning too.

I want about the same speed for my E-Revo when Combo arrives, for me 20/54 about 40 mph, 4s, for the track.
