What are the different properties of the HS-80, HS-81 and HS-85 - I plan to use them in a DAM Mustang, but which should I use where? All are metal-geared, by the way! I plan to use ailerons, flaps, elevator and rudder. Alternatives are metal-geared 6 kgs GWS (standard size), standard Graupner and Hitec (not metal gear), and possibly two Multiplex FLs ... But I would rather save them for bigger models :-)! Thanks for any input, Tord, Sweden -- If reply difficulties - use [EMAIL PROTECTED] Tord S.
