Hello all. I am new to the hobby and I am currently building my first heli.
T-Rex 450 XL HDE. I have everything built and servos installed, except tail servo (back ordered) My question is shouldnt the motor run when throttle is moved up? All servos move fine and I have a steady light on the gyro (401) everything seems to be hooked up correctly, do I need to adjust something in the radio to allow the throttle to work with the pitch servo. As I said this is my first heli and any help would be greatly appreciated. I dont have the receiver or gyro mounted yet, just trying to make sure everything works first. Is there a way to check the esc and motor to see if they work? If anyone is near the Joliet, IL area I would be interested to hook up for a beer and bull session and maybe get some set-up/ training help. IM BUYIN!!

My set -up is: FUT GY 401
FUT S 9650 (back ordered)
Hitec HS 65 servos
Hitec micro electron 6 reciever
align 3550 kv motor
align 35A esc
Hitec Eclipse 7 w/ spectra module :arggg:

Double check what channel you have the ESC/throttle on. Verify the servo direction of the throttle. Is the radio set up properly for the correct swash (mechanical)?

[opsguy49]

Yup, everything is correct. The directions for the esc say it should beep when power is connected and gives info for programming. It doesnt make any noises at all, so I think its no good.

I remember experiencing the same thing when I built my TRex (it's been quite some time though), I think I reversed the throttle servo on the radio and it worked. It should beep. Reverse the throttle servo function and leave the collective stick at bottom, then plug in.

I also suggest setting your throttle hold switch prior and making sure it's engaged. If I remember correctly, depending on the collective stick position the ESC will determine if it goes into "flight mode" or "program mode". It's been a while since I played with my TRex, so I may be wrong..... (either way, I think it won't go to full throttle on start up, but I'd set the throttle hold just to be sure)

The esc was bad, I went and got another one today and it works great. I went ahead and picked up a tail servo also since theres no telling when the backordered one will come. Gyro and tail servo set-up tonight . woo-hoo
