Thank you everyone for responding to my question, you all have been very helpful! I'll look into some better batteries (S2 or S3's) and probably get some FK-180's for the mod I'm working on.

I think the primary drawback with using FK-180s is their price/availability. If you can find them or are willing to pay for them, knock yourself out and enjoy.

Are these actual FK-3240's though? http://www.kysanelec...p?recordID=7071

Also, I don't have a 2S or 3S pack yet, though I do have these 3.7 Li ion rechargeable batteries:

Usually 180 motors have more torque compared to 130 which can sustain rapid firing but require shell cutting.

Alright. But would you think the FK-180 are better than the MTB Rhinos or if the Rhinos are modified enough to be the better choice over 180's? I don't much mind the shell modifications if 180's give better performance.

Just use MTB Rhinos from containment crew.

What are the differences between the two motors? I've heard that FK-180's are overall the better choice over most of the upgraded 130's

I've been looking into modding the rapid strike, and I have a friend that's modding his stryfe, so I've been trying to find some good FK-180SH-3240 motors, though can't find that exact model anywhere (Amazon, eBay, looking through a few forums). Though we have found one possible candidate, it seems to be a KS-180SH-3240 model (http://www.kysanelec...p?recordID=7071) instead of the previously mentioned model.

Could someone possibly point out where I could buy some online (other than a hobby store), or if the link was the correct model? Thank you!
