kv help

[dominion343]

Question I lookin for motor for my miss geico 24 and confuse about the KV. IS THE KV different from the KV IN RC car cause I noticed that in some boats the kv is lower like 1500 or 1600. Can someone help me pls

Generally yes kv is kept lower in boats because of the direct drive vs geared cars.

Another factor is the lower kv with voltage higher will run cooler for motor- esc- in boats. outrunner like 2835-2700 on 3S would be a good choice with a 632 Octura prop that is b & s. Just a suggestion only. Others can suggest also. Single lipo should work out ok for less weight concern.

Wow! !Complicated how will I find the voltage on the motor and how can I find the rite esc and lipo for it? I really like the hobby I was in rc cars in the late 90s early 2000s but now im out of the loop when it comes to brushless and lipo. Im starting from scratch trying to get my mini t and hpi rs4 pro sport2 and now I buy my miss geico24 and the power she came with didnt satisfy me.hope u guys can suggest something for her that wont break my back lol.sorry for sounding like a noob thanks again guys really appreciate it

When you read where boats use 15-1600kv motors, they are for boats using 5S and 6S lipos where the rpm will be close to 30,000 rpm which is the sweet spot for boats. 1600kv x5s =29,600 rpm. 5S is 18.5 volts so 1600 x 18.5 =29,600 rpm. Generally for bigger boats than your G24. I have a Villian which is 31" and I use a UL-1 with kv of 2030 on 4S. 2030 x 14.8 =30,044 rpm with a 440 octura prop. Outrunners have more power than inrunner motors and I suggested a 2835 which can use 2S thru 4S lipos for juice. I would read forums on the G24 to help you decide and give you more info. Hope this helps you out, have a good day!
