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.

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

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...




CHICKEN!!!!!!!
