1350kv...Why did I buy this?

[redshift]

One other thing, compared to your 7 cell terminal voltage of about 9.6-10 volts each, the lipos may feel slow. Keep in mind any voltage advantage with your Nimhs will quickly burn off. The 2250 is worth holding onto, you may find it is a better match for the lipos. As you see the potential of the lipos you will likely want to bump up the speed.

Remember the main advantage of lipos over any other chemistry is it's voltage holding ability, which spells consistency over a full run. I am very used to my 4S Hyperion setup snapping my truck skyward until cutoff. And it's not a light truck by any means...

So the point is, get a few runs with the lipos. Keep in mind any loss in speed will be made up either by gearing the lower kv motor up, or using your 2250. You have the advantage of having 2 motors to experiment with, that is a good thing.

Hope that helped...
