Another instance from Linehart on the "Great Take-offs in Gov. Mode" dated April 29, 2007:
Rudy,
I am loving this "Heli Fixed point" mode. With an APC 12-6 electric prop the Bearcat is flying insides and outsides, verticals and hour glass with proper line tension. I can hear the prop sing differently on the verticals and overheads.
The 4000 amp hour polyquest are consistently recharging at 3.18 amps. My JMP 3 timer is set for 34 secs
zero RPM. Total time 5:15. This is JUST enough time to complete the pattern. The static RPM starts out at about 9000 the settles quickly to 8600.
Thats why I asked the question. Maybe Linehart just got the name wrong.
Yup, BSD Micro does not list the JMP2 timer any more. I did read somewhere that JMP will make more as time goes on.
