The GY502 gyro feels identical to the GY401 with the exception of a faster pirouette rate. The beauty of the GY502 is it gives you software options to adjust the tail control which best suites your flying style.

The GY611 is without a doubt the best gyro offered by any manufacturer to date. If you want the best tail rotor performance, order the GY611.

YOU WILL NOT BE DISAPPOINTED!

Look for the new “Todd Bennett special” Hatori SB-19 in Hobby shops now. It makes the YS .90 SR very happy :~) Countless hours were spent making sure this exhaust was done right.

If you are using the older YS 91 short stroke I recommend the Hatori SB-16 for very smooth power delivery and excellent exhaust note.
