brushless upgrade?
 

I have a 1930-8 and would like to get a meaner motor like the 1940
To keep the same rpm I’ll have to go a 1940-6 which is the same as a 1930-8 but being a bigger motor will it have the same rpm but more power?

It will have a higher amp draw. The higher amp draw will make it have more wattage if the batts are up to the task. Mike raced the 1930 8t and a 1940 7t. The 7t may be slower but can pull a little tall gear.

but is it worth the extra dough? How much more current will it draw? I wanted it for a boat as well so I need it as fast as possible I haven’t made the boat yet I have designed it so it will be out of balsa, carbon fiber, alloy and some small ply it will be light about 24inches or more I was planning to run 4cell then maybe upgrade to 8cell:005:

Well I run the 1950. :) If that helps you.
I like the bigger motors. It just seems to work better alot of times.
Not saying it is right for all occasions though.

Yeah, bigger is better, to a point. Then it just becomes wasted power. I suppose if you made some type of truck specifically for towing something, then it would be OK...

a 1940 can pull a full aluminum maxx with ease.

It's more power than you'll need.

When you lower the turns of a brushless motor do you sacrifice power?
If so can I get the lost power back via a bigger gear ratio? Or would I have lost some power for good?
And I don’t care about gear ratios or amp draw as long as it’s not to insane like 150amps or a 100t pinion lol

If you mean like go from a 9xl to a 7xl. The 7xl will draw more amps. Have a higher
kv as well. You can gear lower for same speed. So then the motor has more
mechenical advantage over the tires. The higher amp draw on same voltage
is more watts which is power. Higher gearing heavier truck means more amp
draw.

I was thinking of going to a 1940 and go for a higher kv like 2613 that’s a 6 turn. is there any advantage in going to a 4 turn 3919kv?
