It's official! Castle have lost the plot (in a good way)

So Patrick... Would the 9000kv motor handle 3s lipo? Maybe with the MMM and a very good 3s lipo. It would be for straight line speed runs, not constant use, and temps would be checked after each run.

No, 2S Lipo max, 7 cell NiMh max. That's it.

The bearings will not survive --

Hmm, what size bearings do those motors use? Do you think the rotor will hold up... If I kill it I will not send it back to you, experimenting is just that, experimenting!

Also are those motors still 2 pole designs? I just wonder as 9000kv at 3s lipo on a 4+ pole motor might be a bit much for a MMM or MM.

Thanks for the quick replys Patrick, always helpful!!

The bearing size is 14mm x 5mm x 5mm, which is REALLY big by 36mm motor standards. . . Helps with side loads and impacts (not than these motor ever actually take any impacts.... ) but is a little hard on the balls and race at really high RPM.

The bearings are rated for 75,000 RPM continuous, 100,000 short term.

Still a 2 pole design.

sounds like a challenge! must kill one on 3s (at my own risk)! is my math off? They are rated over 100k rpm and 3s lipo should be 99900 rpm.

I'll be waiting to see who's going to try 3S first lol. I can see it now, 300-400A spikes, oh man!!!! chase it!!!! it's smoking!!!! Bobby, how can I chase a ballistic missle , just let it burn ?

I will have one of them in my 3S TFE dragster for at least a couple of passes. Not to worry Pdelcast and gang, I always send a check in with my repair orders

My TFE dragster:

That's ungly. I'll take it out of your hands for free though. I'll make it look pretty lincpimp style.
