Georg you are right, The main rotor was 14.63 meter diameter and tail rotor 2.50 with both a big mass and probably an airfoil with low performances. Referring to the French version (was built under US license by Westland) : the helo empty weight was 1994 kg and maximum take off 2675 kg the engine power was only 520 ch. the maximum speed was 82 knt (153 km/h) Blades big mass + underpowered + weight => gave reactions delayed and difficult to fly when the conditions where bad. In order to use it, i first started from the bo105 FDM (every rotor spec and size are coming from it), i gave the s-51 engine power the s-51 helo weight/mass , contact points and mass positions. Everything must be done about the rotor . Sure Maik would be the best expert :) Cheers -- Gérard http://perso.orange.fr/GRTux/ ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
