I purchased a used KOBY 90 for a rebuild of a trex 500 went with a scorpion motor 1600KV and a 11T pinion running a mini V bar and a DX7 at normal end points when I get above 45% throttle it is at WOT have to set stunt 1 at 35% to get it to slow down I have a Kontronik program card but it seems not to recognize it NO lights on the card this does not seem correct could someone please give me something to try

Go back with a linear 0 to 100 throttle curve with default end points and put the Koby into another mode besides mode 4. Then put it back into mode 4. Something was misconfigured in set up because it should hit 100% rpm when your throttle curve is at 80%. Remember a Kontronik governor does not show true rpm and behave as expected without blades attached.

Remember: Check only with a full pack and don't unplug and plug it back in at less than full charge or you'll get an erroneously low head speed. The Koby uses the highest initial pack voltage as the basis for RPM for the whole flight.
