Those of you who have used the Hubin FM timers with Castle Phoenix ESCs (not ICE, not EDGE, but simply Phoenix 35, 45, etc) or Castle Talon ESCs (Talon 35, Talon 60, etc) know that the Phoenix ICE/EDGE High RPM mode settings result in different actual RPM.  For example, I found that my Phoenix 35 ESC produced about 300 less actual RPMs than was set in the programmer; the Talons are different by almost 1,000 RPM between actual and programmed.  Only the Castle ICE or Edge ESCs will match the set RPM between programmed and actual.

I've worked with Will Hubin to add support for the Phoenix and Talon ESCs, and it has been done.  He gave me a new chip for the FM-9 Programmer (requires you to take the programmer board out of the case and swap the chip in the socket - make sure to watch for the chip key orientation!!).  The new chip adds two more modes: Phoenix High RPM and Talon High RPM. With the ESC set to Governor High RPM in the Castle Link software, these two new modes will allow you to achieve actual RPM that are within 30-50 RPM of the programmed value, as I determined with my Fromeco tach.  My son Luca flew his airplanes (SV-11 and Initiation) with Phoenix 35 ESC and FM-9 set to Phoenix High RPM all week at the NATS, and everything worked flawlessly.

You can order upgrade chips from Will Hubin directly; $7 each, shipping included.

Hmmm. Not sure. Call him.

I ordered two of Will's timers with the Talon mode (one with the retract feature).  I received and installed them and now find that the rpm setpoint is right-on with the actual rpm.  I measured 10,600 to 10,620 rpm with my Fromeco tach and the setpoint was 10,620 rpm.   Thanks to Mike and Will for initialing and making this change.
