Upcoming Castle Outrunner Motors - RC-Monster Forums

How much voltage can you run through outrunners in general? Can you stick 10S on a ~800Kv outrunner? This is all new stuff for me.

The max RPM will greatly depend on the diameter of the motor. However, many 800kv motors won't be able to cope with more than probably 6s.

So if I remove the center diff of my truggy and replace it with the 770Kv Castle outrunner, it should be OK, correct? Max RPM with a fully charged 6S is about 19,400. Run times should be much longer than what I get with my Medusa 36-70-2000?

Thanks for your input.

Can't comment on the max. RPM of the Castle outrunners, but as a guess I would say that RPM is too much.
Also, assuming a truggy diff ratio, your theoretical top speed is past 60mph which is IMO too much stress to put on a reasonably sized outrunner.
A kv of up to 550 will net a top speed of about 45mph, which is the highest I think you should shoot for (again, my opinion). Outrunners don't make the same power inrunners do.
