in a flybarless heli u get more stability using a flybarless gyro .....the flymentor only provides stability but in flybearless heli FBL GYRO also compensated for drift due to wind making it even more stable ....if u use a simulator like phoenix fly a flybar heli first then fly a flybarless u will see the difference 

so the votes say it all flybarless is better than flybar and its a better one time investment on gyros ..and saves alot of crash cost ahead !!!!!!

how is kds 800 gyro @ 1700inr . How is the deal..

the price will tell u bout the quality itself dont go for it .......u can go in for their heli kits but not electronics

get the avionic G560 or hobbymate hb790

G560 seems a pretty good option.

g560 n hb790 are of same price
