motor rpm ?

[britscoot]

with 14v what motor spins faster
2200kv or 2030kv?

also can i put 18v through them with a 120amp esc?

thanks in advance

The 2200KV will spin faster, KV is the RPM a motor spins at per volt so at 14V 2200KV spins at 30,800rpm and the 2030KV only spins at 28,420rpm, if you run the same size prop on the 2 motors the 2200KV motor will pull more current than the 2030KV motor in order to spin the extra 2380rpm.

yes you can, but I wouldn't advise someone new to brushless boats to run either motor on 18v unless you have a friend that is experienced with high RPM setups that can advise you on props for your particular boat, that's 36,540-39,600rpm and at these high RPMs you will need a small prop and even a tiny difference in prop load can put the amp draw through the roof and burn stuff up before you know it.

:iagree:
Stick to 4s for a while. 5s on those kv motors should be run in SAW style runs, not just sport boating around. Stick to 4s for that and you'll be good :thumbup1:

To add, it's not just all about KV. Size of the motor and type of motor will play a huge part. Can you please list what motor's you are looking at & what hull they will be or already in? You don't need a some crazy amount of RPM to be fast.

good advise!

i have a UL-1/120amp esc in a 22" hydro.Runs well.
I wanted to try the 1515 1y i just picked up.
The hull looks like it can take it.

Thanks

1515 1y, that's a lot of motor in 22" hull. I would personnally stick to the ul power, but maybe someone else that maybe has tried it or knows more about it can help. It maybe to much though.

[britscoot]

with the UL motor it is very stable and turns flat out.

I wanted to push the envelope a little.
cant hurt to try....

[britscoot]

looks like i will gain a couple of thousand rpms with the 1515.

oh brother!!!!lol

[britscoot]

scratch that idea!
its quite a bit longer than the UL motor!

It would end in tears.....lol

sorry have to do this...
