I'm looking at the Futaba 401....at $140 from Tower, it is not a terribly expensive gyro, and if nothing else, it'll give me a basis for forming opinions and making judgements. I'll just run my standard rudder servo (Hitec HS-645MG) on it and see what happens. I am thinking that this gyro is switchable from the Tx, so I can turn it on or off as I see fit. That should give me the straight lines for take off and landing...which is my main focus, and then turn it off at high speeds to avoid tail wagging.
Myself and a few friends play around with formation flying with giant scale warbird planes, and the T/O and landings in particular is where you really want to maintain your designated line on the runway.
( It gets real noisy if you mess up! )
Thanks for all the advice....I guess now it's time to take the plunge....if I can just get it before Futaba discontinues this one too!
