NiMH or Li-Po?

[liborlad]

At the moment I'm running a CF/Al Gmaxx chassis with UE and GA upgrades in most places on my Emaxx. I'm now planning on changing to a brushless system and was pretty set on a 9L/9918 combo with 7 cell GP3700 packs.

This would cost me about $360 for the motor and extras plus another $300 for 3 sets of decent batts. However I've been reading the discussion you've been having with lipomax and I'm thinking maybe I'm going in the wrong direction.

Would I be better with a 10L or 7xl running with a 6s Kokam 3200 setup? Are the feigao motors up to this, should I now look at the lehner motors?
Would these batts fit OK on the Gmaxx chassis? Will the koolflight UBEC work OK with a higher input voltage? Can the 9918 work at the higher voltages these cells run at?

Sorry for all the questions guys but I'm now very unsure as to the best way forward. I'm not using the truck for racing so top speed is not a major issue, anything around the 40mph mark would be more than enough for me. I am interested in real good punch combined with long runtimes.

I'm happy to spend around the $600 mark for this upgrade. your views would be appreciated.
