The later offset gimbal head provides much better stability than the original spindle head.
I whole-heartedly agree!
I first learned to fly gyros using this spindle type head on a towed glider. On the glider the tow line and weight of the tow vehicle tames it down a bit, but in free flight it is absolutely
treacherous! The control pressure feed-back and reactions to disturbances are exactly the
opposite of self stablizing. It is trying to kill you every second!
Igor Bensen knew and admitted this in is book
"A Dream of Flight".
In fact I would go so far as to state that without the introduction and adaptation of the off set gimbal rotor head, the sport gyro movement would have died in its infancy.
In short, don't fool with that thing. Get yourself a good offset gimbal head. Your entire flying experience will be much enjoyable and
SAFER!
