thanks, so pitch is set, rotor track nicely after i did a quick spool up in the front yard to see if the rotor are tracking evenly, gyro is now the next thing. so heading hold is what the gyro should initialize in? or is that for 3d only, when i spooled it up the gyro was in normal mode(gp780 with green light on) and the tail held for the start but when it started to drift and gave it a little rudder, it just spun out so i was still on the ground but barely on the skid and i killed the throttle. i honestly have no idea where to start with gain values in my radio.

just make sure you read the instructions on the gp780 its not quite as simple as the 750 was. but it sounds like your gyro direction is backwards. and i recomend setting up the tail in rate mode then flipping it into heading hold, setting your gain then forget about it.

no need to use rate mode imo

Who cares... its just money...

the bob finless videos are one of the best things to hit this hobby for new folks ever.

letting that one get away was exspensive.

Ok so after reversing the gyro channel in the TX, and setting my gains at 0:72 and 1:40, the gyro intializes in HH mode and when i flip the switch to 1 it switches to rate mode. now the question is how do i test the gyro on the bench to make sure HH mode is HH mode before i try to fly. so far when it's in HH mode and i move rudder it centers back quickly but in Rate mode it stays at the stick throw and have to move the rudder back to get tail to go back. thanks

in heading hold the rudder servo will stay just about where you move it to. and in rate mode it will snap to center.

just take your time and make sure that you input mov es the blades the right way and that the gyro is correcting the right way then go hover it. if it drift pump up the gain if it seeks lower it.

same old crap. personally i hate it when my tail won't behave right.

Who cares... its just money...

i did the pinch test and when i move the tail(from behind the heli) to the right it pinches. but i will set my gyro back to normal in the radio and play with it again. thanks
