Set-Up Choices 32" CAT

[Alexgar]

Running the 9XL on 4s in this boat would give you about how much speed?

Probably 35-40 mph

Use high C rated packs (30-45C) and you can get away with running 1p.

The pack configurations are quite simple really, it doesnt require much learning. "s" stands for series, and "p" stands for parallel. From that you can figure out what you have. The number in front of the s will dictate voltage, while the number in front of the p will suggest what your total capacity is. From there you can figure out how you want to accomplish your configuration.

You will get a million suggestions on what to run, especially wihtout specific goals. If you come up with an amount you want to spend, a speed you would like to attain, and a runtime goal, you will narrow things down a bit.
FYI- There are a couple combos listed here that I personally wouldn't reccomend running on a 120A esc. Just my opinion, but pushing the current limits of your esc is only going to shorten your runtime anyway. Let us know some more specific goals and we can send you in the right direction.

Also, More mah doesnt always mean more runtime, especially at the expense of voltage. My 32" cat is running 5000mah and getting more runtime than any other cat I know of at the speed I am getting.

Keith,

After all the great input from everyone, I think I'll opt for the 2s lipo's (35 C Hyperion) in series for 14.8 volts. I've a 10 XL (1668 KV) available for testing in this hull. Remaining item is the prop. This is a sport boat and I'm looking for the 30 to 40 mph range with good run time.

Thank you to everyone for their input into a first time boat project.
