Post subject: Flybar alternative materials ? |
 |
|
Trex 450 SE V2 ..... (clone) .....
When will someone come up with a flybar material that is more suited to the job ?
Thin metal rod is IMHO prone to damage without even crashing .... any touch ... even when I've moved the 450 - I've caught the flybar and that's another one bent.
Is there any other flybar available ? One that is not so easy to damage ? I realise that you don't want something that is too strong as then you damage something else ... but present is ridiculous ! |

Easiest solution is to go flybarless, not cheap though.

But - I may be wrong ... flybar less is more twitchy / sensitive ? Not exactly a beginners set-up ? |

Be glad that the flybar bends rather than something else. Flybars are real cheap. You can make one yourself.
There are carbon fiber but remember the tougher the flybar is then the damage gets transfered somewere else.

I appreciate that you don't want it too strong ... but the present bar system is so poor - there must be better ........
CF ? where - any links to sellers ? |

Hi solentlife,
With the 3 axis gyro taking most of the strain the flybarless helis are almost like co-axials to fly, but good wind handling and without the blade strikes. Take a look at some of the new Walkeras, they are really amazing.

I'm temp. financially embarrassed - so purchase of another heli is not possible ...
To change to flybarless - would that mean replacing the Gyro I presently run ... a G105 ? Despite it's obvious clone / budget origins - it does an excellent job.

I'm still interested in possible replacement material flybars that would be more suited to training modes ! |

was thinking of the same problem with my kestrell..(new on this as well) i am thinking of finding a tube similar to an injection needle of a softer metal/alloy might be strong enough to be straight but weak enough to break or bend when it crashes.. hmmm this is what is good about this hobby..you think of all sorts of remedy I know its crazy but ever thought of going organic like a lightly laminated bamboo stick? it can be straight and will break you can go as thin as a few milimeters and still be stiff enough.  |

There is more stress on the flybar than just twirling the ends around. It is another gyro whose job it is to trim the rotors against adverse movements. To do this it needs to have a high degree of ridigity or else the corrections will not be fast enough and can result in a cumalitive control action giving the dreaded TBE or even total loss of control in the worst case.
Slackness or over tightness in the linkage/seesaw can also do this. Looking at the bamboo growing around here I doubt that it would have the stiffness required for accurate control until it was thick enough to effect the flight times due to excess drag. Remember that most of the heavy strains will be in the vertical plane - the worst one - in this case - to thicken for flight!
