May I use this gyro with a helicopter with tail motor, no tail servo?

Theoretically yes

No, this gyro put out a signal for servos. This is a PWM signal with long LOW and short HIGH periods. The length of the HIGH period defines how far the servo should travel. Your motor (I assume its non-brushless) needs a certain voltage to spin at a certain rate. The higher the voltage the faster it will spin. These are two totally different concepts.

hello is there any way to make this a standalone gyro for a tilt camera? i want to connect only the servo and power to the gyro, and it will just keep a horizon. nothing to do with a tx/rx

The gyro is amazing. I used it in the road car model to manage and everything is in perfect order. I recommend this product for its sensitivity and price.

i figured for the price i couldnt resist trying one of these and i am not dissapointed this things works great just as good as my 401 futaba gyro you need to look at the mods section on this as i had to do that but the little time i spent doing the mod was more then made up for with the low price and great performance
