Hi.

I own a impulse v2 31 stock setup today and one i know want to buy impulse or miss geico.
What is the big difference except the hull?
Do the cat get faster accelation or top speed?

The impulse have 6s esc and the cat have 4s esc.
The motors is 1800kv on impulse and 1500kv on the cat.

What is different with lower og higher kv?

Last question. How fast should both go on stock setup with the same battery packs?
