After comparing half a dozen heli’s, and changing my mind every other day, I finally bought a replacement for my Raptor .50. The verdict became the Align T-rex 600E Pro. Since I was planning to use a Castle Creations ESC anyway, I went with the Super Combo.
The partlist, mostly included in the Super Combo:

- KV = 510 rpm/V
- Input voltage: 11.1V – 50.4V (i.e. 5700~25700 rpm)
- 12 stator arms, 10 magnetic poles
- Continuous current: 75A, bursts 125A⋅5s
- Continuous power: 3.3kW, bursts 5.5kW⋅5s
- Phoenix Ice2 HV 80 ESC
- 80A continuous
- Governor built-in
- Logging built-in
- 3x Align DS610 servo on the swash
- Digital
- Torque: 9.6kg⋅cm at 4.8V, 12kg⋅cm at 6V
- Speed: 0.10s / 60º at 4.8V, 0.08s / 60º at 6V
- 1x Align DS650 servo for the rudder
- Digital
- Torque: 4kg⋅cm at 4.8V, 5kg⋅cm at 6V
- Speed: 0.06s / 60º at 4.8V, 0.05s / 60º at 6V
- Align RCE-B6X external BEC
- Input voltage: 2 cell LiPo (7.4V)
- Output voltage: 5.8V
- Max current: 6A
- LED voltage monitor built-in
- Linear regulator
- I kept my R319DPS receiver from my Raptor
- 35MHz band, synthesized
- 1024PCM receiver, 8 proportional channels, 1 digital channel
- Align 3GX flybarless system
- Input voltage: 3.5V ~ 8.4V
- Current consumption: <80mA at 4.8V
- Gyro range: ±300º/sec swash, ±600º/sec rudder, 12bit resolution
- Software included on 8cm CD, which I was unable to read in my slot-loading drive; but also downloadable.
- I immediately upgraded the firmware to v1.2 (local copy)
Build notes
- Page 5: The main head was pre-assembled, but wasn’t tightened. Make sure you check all bolts and loctite them in place. I also added a generous amount of grease to the thrust bearings.
- Page 7: I waited to mount the motor onto its mount until I figured out where I wanted to put the ESC and the 10AWG cables.
- Page 7: Although the drawing is correct, it wasn’t clear to me that the bottom “Main shaft block” had to be mounted upside down compared to the top one. I only noticed that by page 16 when I kept having slop in the main shaft, even with both “main shaft spacers” inserted.
- Page 13: The tail head was also pre-assembled, and since I was unable to loosen the screws by hand, they seem to be tightened (maybe even a little too well)
- Page 17: Fitting in all the electronics into the tight cockpit isn’t as easy as the manual makes you believe…
