Just a quick post. Some people who have flashed their Turnigy 9x to use the er9x firmware can load my Xieda 9958 model into their radio using the eepe (EEPROM Editor for er9x FW). You can get a copy of eepe for Windows, Mac and Linux here: http://code.google.com/p/eepe/
Then use the eepe program open up my Xieda 9958 model and save it to yours.
Some info about the settings…
Two primary flight modes:
- The FN switched to ID0 will put your heli in a more aggressive mode. Negative expo to make your cyclic controls more sensitive in the middle. The throttle curve is a little more aggressive. Uses curve 1.
- The FN switched to ID1 has zero expo and a more “gentle” throttle. Uses curve 2. If you want a linear throttle curve. Set your throttle stick to use curve 3.
Flip the rudder D/R switch to add more negative expo to the rudder. If find it’s good to have the head of the heli whip around quicker using the negative expo.
POT3, which is labeled as “PIT TRIM AUX.2” is a mix that adjust endpoint. Fly with that POT at 100% for full throw. Rotate it slower if you need to go into “junior/beginner” mode. Same function as the factory transmitter junior/senior mode, but with more choices in between. :D
The flight timer is set to 5mins and will beep at the last one minute and each of the last 10seconds of flight. It is link to the throttle stick so the timer only counts down when the thottle stick is move away from zero.
Lastly, the throttle cut function works. Just activate the throttle cut switch and your main motor shouldn’t spin. Good safety.
Let me know if you guys have any difficulty and I can write up a more thorough guide. Also, remember you need to calibrate not only your sticks, but your POTS as well. It’s all done in the same location. I do it each time I flash the firmware.
