Brushless motors
 

I have always run brushed motors graupner 700 neo, with jetti 600navy. but i now have a bigger boat, an the motor is not right so my question is what do i need to no before i get a brusless motor?

new esc?
new battery pack i run nicads?
diffrent shafts an props?

simple things which may or will make a diffrence thanks chris

RE: Brushless motors
 

a brushless motor will probably laugh at your nicads , they are 2 or 3 metal advancements behind. yes you need a new esc to go brushless, should be able to keep the shafts, keeping the prop depends on the new motor

RE: Brushless motors
 

You should start by selling me your 700 and esc for a good price

In my boat club we run spec classes in which we run stock Aquacraft SV27 and UL-1 motors or the stock Proboat black jack 26 motors which are cheap for their level of performance. We also run unlimited classes which can use any motor, a high performance low price one are the Feigao motors which come in all sorts of sizes. You will need a new esc specifically for brushless and currently our club runs lipo battery packs. You can get everything you need and learn more at www.offshoreelectrics.com.

nicads will not keep up with the amp demands of brushless motors ;)
go lipo, they are getting cheap

RE: Brushless motors
 

ok so a new esc an batts then, dont fancy lipos. So the nicads will work but drain very quick so its goin to be very expensive to swap over chris

RE: Brushless motors
 

nicads will not work in my opinion because they cannot keep up with amp draw of a brushless motor, this will cause the cells to get very hot and damage them.
also the small capacity of them will not yield very good run times at all
lipo batteries are very easy to charge and maintain

RE: Brushless motors
 

what size is the boat...... this determines the size of motor, batt and esc

is it for fun or competitions

i see your determined to run nicads and as people have pointed out, lipos are much better but if you dont want to go with lipos then theres no point going brushless

RE: Brushless motors
 

Guys are right... first change will be to go Lipo. I can confirm that even a brushed system will go though a noticeable change if you go Lipo. A bit like a new boat, as far as response. Check some of the prices here:

This will give you loads more power and the price is not that different from a good NiMh pack. BTW, if you login, the prices go down...
My opinion: go Lipo first, get the taste of it, than slowly upgrade. If you run scale boats, there is no real point, as the speed of a brushed system is a lot more scale...

RE: Brushless motors
 

I agree with Cornelp.
If you were to just change to lipo even with your brushed motors you would see a big jump in power! ;)
and not much money spent doing so

RE: Brushless motors
 

maybe lipos must be an option, what happens if the inside gets wet? was told to keep lipos dry??? iam running 3 boats graupner b24- gancia dei gancia an my new one which blow the brushes 32inc twister mono. but will really look into brushless-brushless esc-lipos

RE: Brushless motors
 

just like most electrics that get wet, let them dry out completely before turning them back on..
lipos will be just fine
