RE: Rotor Hub Dimensions
Hi ya'll,
First do believe rotor size and model weight plus flying speed all effect
the airstream force the rotor sees.
Believe the the larger any of those items are the greater the ASF! and the amount can increase dramatically with minor increases.
There seems to be a simple answer to all rotor control needs at least up
to 60" rotors. FMA direct has a jewel of a standard size servo with 120 in oz and at a reasonable cost. Model # PS905MBB
Learned the hard way> with a 5 to 6 lb craft with a 54" rotor you will need at least 1200 mah batteries!
Good luck!
