I am having trouble programming the MM using the 3PK. The receiver that came with the radio is a HRS (high response system) and transmits data too fast for me to keep up with the beeps. In the 3PK manual, it says to use a DSC cord and a two way cord to program any non-futaba ESCs. I have tried this, but i am still having problems. Has anyone programmed a MM ESC with a 3PK with a HRS receiver?

I know I can program it on a computer, but I only have a Mac

You could try to switch modulation. Try PPM. Page 16 in the manual. I have to admit that I haven't tried this myself with the 3PK, only the EX-10. It should work though. I don't know if you can switch back to HRS after programming the esc and keep the settings you stored in PPM mode. Do you have a digital servo?

Servo is digital, the manual says that you must use a DSC cord and a two way cord, but the guy at the local hobby shop said i could plug the dsc cord into the hrs receiver and plug the MM into the receiver, but this created the same problem. Can i use PPM mode sith a HRS receiver, the manual says not to.

I just thought you could try programming it in PPM or PCM mode and then switching back before you start using it. As I said, I haven't tried this myself and don't know if the settings will be deleted when switching back HRS.

Theoretically it should work, since the settings I am worried about are kept in the ESC, not the transmitter, so switching modes on the transmitter should not matter. I wonder if the transmitter will transmit through a HRS receiver in PPM mode. The fact remains that I am still trying to program the ESC through a HRS receiver, so it is a speedy signal problem. I could use another futaba receiver that was not HRS and just change the crystals to program the ESC, but i do not have any fm futaba receivers, only am. Probably gonna just have to use my brother's pc to get this done. Thanks for the help.

I think you still need to do the basic programming with the radio. Not 100% sure, but I think that you have to do the basic forward-nuetral-reverse with the TX. Everything else can be done with the PC.

That is not a problem, as its just hold the throttle then brake, it gets too tricky later on in the programming when you have to determine between 7 or 8 beeps that all sound like one.
Does the HRS receiver perform much better than a normal fm receiver?
