I started building my third 450 about 3 months ago with all the bling stuff, ally this, ally that, CF this and CF that, you catch my drift? The build also included an FM as orientation is something I have always had problems with. The other 2 I also build my self and they fly 100% correct, ( I love building, flying is ok) I have up to now not been able to get this heli to fly, it is a HK450GT,
Initially I had cheap HXT 900 servos on it, just over half throttle they would start jumping up and down, I rebuild, ran the power wires one side and servo wires on the other side, same thing, thought FM was causing problems, removed it, same thing, though Walkera ESC was the problem, replaced it with a Turnigy Plush and still the same problem, bought Hitec HS-65HB servos (wow they are not cheap) same problem, swapped motors from one of my other helis, a Turnigy Typhoon 2218, same problem, stripped al the movwable parts today, and spun the motor after each bit got cleaned and put back, bit by bit..........................PROBLEM FOUND...........CF TAILBOOM........it was causing such vibrations that none of the electronics were working properly, replaced it with a normal one and spun it up inside the house, it seemed ok.
Now we are having a terrible windy,stormy day, but still thought.......stuff it, the heli doesn't know there is a terrible wind blowing............it made for challenging hovering..............BUT..............for the first time this heli flew 100%, wow I was happy, for 1 battery pack she flew and did everything exactly the way I told it to do.
Must admit, a lot of the stuff I tried was from trail and error I read on this here forum, IOW to everybody here who have had problems and to every one that has helped those members.....here is a BIG THANK YOU........all of that is what helped me sort my problem.
Now I can for the next 2 hours teach my 10 and 11 year old sons how to build helicopters, the are both busy with 450's, we do this every Sunday for 2 hours
