If you want to replace a 3 kg motor (Bosch 750) with a 600 gram motor (propdrive 5060) you'll need more of'm.
Also, smaller motors run faster (the slowest propdrive is 270 KV, 2 times faster than the Bosch 750)
In short, if you want to have the equivalent of a "bosch 750" drive in propdrives 5060 you want at least 4 of'm, and be prepared for a higher gearratio.
One other thing I was wondering would any of the following in the link below work in a HW or MW?

I know NPC T64 are the way to go but, I'm looking at other options as well.
The NPC-02446 motor is advertised as "great" for lightweights.
The data from Robot Marketplace gives this motor a 500W rating.
You can get a heavy moving with those, but you won't be happy with the results.
If you want any acceleration, you'll have to use a gearratio of 6-7 to 1 with the 4" wheel. Trundling around @10kph. But you'll be there in a jiffi.
Have a look at what Ellis did with Sandstorm - good example

Maybe I didn't notice but, what motors did he use in Sandstorm?Quote:

I guess something like the Rotomax 80CC or bigger.
Bananaking, a Russian machine, uses Revolt motors, and because decent Brushless controlers for this kind of power ain't common (MGM Compro is one of the few commercial options at €800+ a pop) he went with Euans 300A VESC's (see that thread). Another thing were Ellis is involved with.
On Sandstorm its a really small package for a heavy
They are Maytechs either 50 or 63mm cans - one per wheel and a low ratio, something like 4.4 : 1
There is a write up somewhere, maybe instagram
So, 4 motors . As I stated at the start of this topic.
If I combine the data I can find easely on Sandstorm,
24mph(almost 40kph)
4-1 gearratio
Guess on 5" wheels.
Maytech 50 or 63mm motors.
I guess the Maytech MTO5065 170 HA-C is the lightest option. 1800W+ each. 7Kw of drivepower. Sounds a bit like 37V powered Bosch 750's or equivalents.
With 1 size bigger, the MTO6355 170 HA-C that power about doubles per motor. Giving the very nice 14Kw...
Not 1 kw of the NPC drive proposed in this thread.

By all reports its physically small for a heavy
Yes, and that is the advantage of brushless outrunners. More efficient, and if chosen well, not that expensive per Kw on the wheels.
The days of £1000 for 5Kw are gone.
