ORIGINAL: XE521
The original Rotodyne used a fixed rotor shaft. Due to the problems of routing the linkage around the air ducting etc. they located the swashplate in the dome housing above the rotors (see below). Because the Rotodyne took-off as a heli the rotor angle could be kept to an absolute minimum. If you want the angle I'll leave it up to you to calculate it from the dimensions show below.
Thanks for the explanation. I wasn't completely sure about the rotor system used on this craft; it's an interesting design.
Referring to the model, I'd say a DC rotor was probably the best solution regarding simplicity, reliability and cost (if there's enough room for the rotor to tilt, of course). A swashplate has more versatility, but that comes with a significant increase in complexity and weight, which IMHO are heavy arguments to go for the DC rotor if you don't need that extra maneuverability.
BTW, very interesting pics! Could you please send me too those files you mentioned earlier in the post?
