Servo / Gyro Articles

Which servos you use tends to be a matter of personal preference but for the hard facts refer to the
following comparison table.

TrexTuning recommends the following configuration for a good 3D setup:

Hitec HS65MG for cyclic
Futaba 9257 for tail

 

This following table lists a number of gyros that could be used on the Trex. Obviously any gyro 'could' be used but I have tried to list here the ones that are small in both size and weight and therefore are more suited to a micro helicopter such as the Trex.
I'll try to add specifc information for each gyro as and when I get the opportunity to try them and set them up on my Trex test machine. In the meantime you will have to make do with the manufacturers default information and setup instructions.
I have only listed heading hold gyros as a way of keeping the list fairly short and comprehensive. I'm sure there are many more than I have listed but I have also tried to keep to main brands in the interests of brevity.

Also accompanying the various gyros and their reviews is this useful guide to gyro's by Steve Peregrine :

Once again TrexTuning has some recommendations on the gyro to use for your setup:
