PowerBox iGyro 3extra


Sold Out

The iGyro 3xtra starts the second generation of the iGyro family. The new iGyro 3xtra boasts a completely revised regulatory algorithm and set-up procedure, expanded features and enormously enhanced performance, making it the new “State of the Art”.


In contrast to its predecessor - the 3e - the new iGyro no longer incorporates delta and V-tail mixers. Instead the iGyro has a new, simple learning process enabling it to detect all servo mixer combinations, which can even include differential and unequal travels. The user simply sets up delta control surfaces, V-tails, flaperons and tailerons at the transmitter in the usual way. A sophisticated three-dimensional algorithm then divides up the control commands again into aileron, elevator and rudder for all five inputs individually. This method ensures accurate suppression of the individual axes when control commands are given, or when the heading function is in use.

Another significant innovation is the learning process for the installed position of the gyro: this simply involves movements of the model itself. At the same time the procedure also defines the directions of effect in the iGyro. In the past many pilots have been unsure whether they have actually set the direction of effect correctly, but this doubt is now eliminated.

If you are at the flying field and don’t have a smartphone with BlueCom Adapter or a laptop with USB Interface Adapter to hand, you can very easily adjust the gyro’s gain for each axis individually and accurately using the transmitter sticks - without any additional equipment at all!

The hardware has also been subtly improved: the unit now features comprehensive ESD protection to provide a complete shield against static charge problems in the model.

Supplementary features such as gyro characteristics, stick priority and lock-in feel also give experts the means to customise the iGyro 3xtra to their exact personal requirements.
