this is my first flybarless system . can i still setup my endpoints or trims with the radio , or am i limited to using the computer program ? i don't want to screw it up .

Make sure all trims are at zero, tail and cyclics. Leave your end points at 100%. Then when you program the BW you set your +-12 degrees by the BW and let the BW know where your 8 degrees is. You also program cyclic travel and make sure there is no binding on the BW. You also set your end points on it for the tail. If you get more travel on the BW in one direction on the tail move your servo up or down the boom until both end points are nearly the same. When you are finished adjust the rest of the pitch range with a gauge to your liking. Before flight turn both pots on the gyro to 11 o'clock and go from there. Make sure your blades etc are well ballanced and the heli runs smooth in the first place. There is a video one of the lads here done that may help you and I would recomend looking at it if you do a search. Good luck......you will love it!

thanks valkman . so its all done with the BW as I thought. so the only thing i can do with the radio is the pitch and throttle curve . i did get binding on the tail with the BW but then i adjusted it with the radio settings . my BW settings on the 450 are at 1:00 and seems pretty good their . its raining here now so no more testing today . thank you again.

You set the end points on the tail also with the BW. If you get binding reduce the limit with the BW. As I said if do this and your ends points are different in one direction than the other move your servo up and down the boom then re-adjust the tail limits on the BW. Do this untill the limits are nearly the same. - +10 should be ok in either direction. Before you fly make sure the swash moves in the right directions when you tilt the heli. If you tilt the heli right the swash moves left. If you tilt it forward the swash tilts back etc. Basically the swash will try and stay level when you move the heli. If its wrong as soon as it lifts off the heli will flip over so make sure this is right. Let us know how you get on buddy.

yea , i cant slide it . all i can do is set it with the ball links . but that wasn't the problem , it was the ball link . i had it too far out on the arm. i still needed to adjust the epa though .

Ah I see. You have a fixed servo position. Reducing the EP on the TX will also affect the piro rate. I dont understand why you cannot adjust it enough from the BW. Does your tail pushrod not have enough adjustment on the links? If so can you not modify it ( make it longer or shorter ).

i can , it was easier with the radio lol

i took it for a quick flight today . it wanted to flip over then realized the elevator was reversed .?.? i tested it before and it was fine but somehow it got reversed . I fixed it and flew almost perfect . It was really sensitive on the cyclic so i added some dual rates and expo . i wish flybarless was around when i was learning to fly , it makes flying smooth too easy .

Glad it all worked out...btw, somehing I remember as someone once told me about FBL helis. When you first spool up and taking off, try not to add any cyclic inputs as the FBL system will try and fight you on this and cause the heli to tip. I thought it was very interesting as thats exactly what happen to me on the very first time.

Dr. Evil , i heard the same thing but this felt more like flying with a flybar but more stable. hard to explain but my flybared helis are literally hands off flying , this was similar but smoother . on takeoff it handled just like a flybar as i still gave it some adjustment . it really felt like it had a flybar , that's the only way as i can explain it . the only time it felt under gyro control was when i let the controls go , it just sat their happy in one place , not like a flybar .

i got a bit of a problem with a flybar , to make it more stable i raise the headspeed . for a flybarless system raising the headspeed makes it super quick . this would be great for 3D or even 4D but not for normal flight . i already have expo and D/R set and don't want to go any lower . i am thinking 8 degrees of cyclic is too much, should i reduce it in the programming ?

Can you not adjust the end points on your elev and aileron and leave the pitch as is? You probably will so something different anyway lol! You could have a look and see what others are doing on their Beastx etc.

never mind ,figured it out ;D i did alot of reading on flybarless systems and my setup is spot on , its the blades their too light . i tryed heavier fiberglass blades and it was perfect . light blades makes it way to agile for me , i will let the experts fly that way

I may be stretching mine to a 700 at some stage so I'll bear this in mind.
Happy flying ;-)
