Upgrade to a Lehner... Which One?

[jhautz]

OK I think Im ready to upgrade to a Lehner 19 series motor in my E-Revo. I want to find a setup that will be able to run my entire 8000mah 5s lipo packs in hard bashing conditions with out stoping to let the motor or ESC cool down. I'm lookin for advice on which size and wind to choose. I want to get the best setup I can at this point I'm tired of always walking the line with heat. Granted I don't want to replace everything. Just the motor. Cool and Stable is my goal. However, I would like to make sure I keep at least 40-45 mph as a top end. I bash w/ nitros frequently and still want to be able to keep up on the top end.

Here is my current setup. I would like to be able to just keep the setup I have and put in a new motor, spurs and pinions.

E-Revo G-Maxx chassis w/ Gmaxx Motor Mount
580C-9XL
Quark MonsterPro 125 w/ heatsink and fan
2 Speed Emaxx Tranny - Ultramaxxed
70/24 32P Gearing
RRP Slipper Kit (I have a Strobe in the package still, will be upgrading with this rebuild)
TrueRC 8000mah 3s + 2s Packs.
RRP- Rear Diff gears w/ Aulm. Cups and Case
MIP CVD Rear / Stock Sliders Front
Dual 5925MG steering Servos
M8 Radio w/Spektrum


I am planning on continuing to run the 5s packs for the most part, I would however like to be able to run a 6s setup ocasionally (just for showing off to the nitro guys).

My initial thoughts are to go for the 1950-7. I am a little concerned about the sheer size of the motor. Looks really big and really heavy. Would a 1940 can due just as well for me? I don't really want ot get into making support brackets for the back of the motor and such.

Just looking for some input to make sure I make the right choice. To me this is a lot of cash to drop on just a motor, so I want to make sure I make the right choice.
