I want to start with an apology if this question has been asked and answered somewhere in this thread of 2500+ posts. I tried a search but didn't find my answers.

I recently picked up a used 1/8th e-buggy with a gen 2 RX8 and 1900 T8 G2 motor, and the hotwire interface - gen 1 I guess since it's a black case.

The motor and esc seem to be very clean and in great shape... But, the fan is missing a few blades. Guess that's still a problem since the Gen 1 RX8 I had 3+ years ago also ate fan blades LOL!

I'm looking at fan options. I read somewhere that the fan is only rated at 5 volts, but the voltage fed to the fan is dependent on the main pack voltage. So a 4S or 6S is way over voltage for the 5v fan.

Is this true? Or is the voltage out to the fan regulated at a certain voltage?

If so, what's that voltage?

What's the best replacement fan option?

Any way to stop breaking blades?


Again, sorry if this has been asked/answered somewhere.

Thanks in advance for any help.
