The fan operates at constant speed so the rotating mass of the motor structure is not an issue. It should actually help maintain constant rpm, thus requiring a less torque motor.
Yeah, I think you're right. I don't know what's the required force to overcome the blade resistanceZeitgeist said:But a strong (driver) motor is key........right?
I just can't wrap my head around how you could get the force necessary to drive the linkage to change the blade angles - if you don't have a strong motor.
It seems like a lot of things can be fudged...... xmax... the rotational speed.. blade sizes....... But if you can't accurately control the linkage, nothing else matters.
Correct, they have some new, very high Bl drivers.Maybe it's just high B that people are after with Fi.
I think royalties may push the price up considerably if they were mass produced.Man, I sure hope this can be finished. If a person can (somewhat) mass produce these at a considerably cheaper price than the Thigpen, I think they could really make some dough. I'm not positive though...just a guestimation. Haha.
That's what I was assuming as well. Too bad. I would love to try one of these things out. I have a large closet in my room and it would probably fit perfect in there. Haha :bigsmile:robbo266317 said:I think royalties may push the price up considerably if they were mass produced.
I thought that was the whole reason why the Thigpen uses a GE? motor/speed controller is to maintain RPMs?Not sure of the shaft RPM (SRPM) of this system, but when the blades deflect, drag is imposed. If keeping the SRPM constant is important, then the max drag/resistance needs to be accounted for and consistantly overcome, without burning out.
