| The Hirobo Chinook is a very fascinating helicopter. It is a very complex machine and I think we could all learn from each other if we share our pearls on how to make this helicopter fly better. Now that we have a subcategory for tandem rotor helis, this would be a great place to share this information.
I find that blade tracking is very important on this helicopter and it is hard to check on a tandem rotor machine because you have to simultaneously look at two intermeshing sets of rotor blades.
What I do is remove the rear set of blades first. Then I spool up (but not to the point where the helicopter takes off) and watch the front 3 blades rotate and then adjust tracking. I use different color tape for each of the three blades to determine which blade(s) is out of alignment and then I adjust the ball link to get the blades to track properly. I then do the same procedure for the rear blades, removing the front set so I can concentrate on the tracking of a single set of blades.
I find that with both sets of blades tracking correctly, the Hirobo Chinook flies significantly more smoothly. Any variance in tracking really hinders the stability of this helicopter, much more so than a pod and boom heli in my experience.
Hopefully others can share some pearls to help us all get this helicopter flying smoothly. |
