T-Rex 450 SE V2 with RX601
on request, my T-Rex 450 config
hardware:
ESC: Kotronic Jazz 40 LV (Governor Mode and Soft Start configured)
Gyro: GY-401
Motor: Stock (3700KV)
RX: RX601
rx channel assignment:
ch1 (ele): rear swashplate servo
ch2 (ail): right swashplate servo
ch3 (thr): esc
ch4 (rud): rudder gyro
ch5 (gear): left swashplate servo
ch6 (aux1): gyro sensitivity
dual rates:
rud dr: 100% & 80%, no expo set
ail dr: 100% & 80%, no expo set
ele dr: 100% & 80%, no expo set
be careful, heli is kind of agile with these settings, add as much expo as you like.
switches:
gear: autorotaion and/or panic switch, sets throttle to -100%
fmode0: throttle is bound to the throttle stick, min pitch: -3 degrees, max pitch: +10 degrees
fmode1: throttle 80%, min pitch: -10 degrees, max. pitch: +10 degrees
fmode2: throttle 90%, min pitch: -10 degrees, max. pitch: +10 degrees
you might configure some throttle curves, if your esc is not in govenor mode
gyro sensitivity:
GY401 works in AVCS mode, if sens channel is larger than 0% and in normal mode, if smaller 0%. The sens can be modified by using the trim buttons next to the “mix switch”, the current value is also shown on the main page. A good startpoint is 80-90%.
basic setup procedure (for those people, who don't know how to do):
1. move sticks to neutral postion, all swashplate servo arms should be aligned perfectly horizontally now, if not, correct the position physically, then use subtrim for fine tuning
2. in this position, pitch should be 0 degrees for both blades, if not, correct it physically
3. to set minimum and maximum pitch (i use +/-10 degrees), use min and max settings of the three “swashplate channels” (ele, ail, gear), but always use the same value for min or max on all three channels (be careful here, gear is inversed, so min = max and max = min!!!)
4. you are done, have fun.
