Finished Build...but with lingering question

SandMan123 · 12-02-2010, 07:59 AM

So I've done with the build now...but with the linkage setting called for in the manual the swashplate rides too high on the shaft, and there is not enough positive pitch and too much negative. I know how to fix this, but my question is: are the linkage lenths way off?

Sandman, my flybarred one ,using Futaba BLS451's was almost spot on, just required a few turns. My FBL one needed a few more.
The link recommendations are just starting points that will have to be adjusted to your servos. Slight differences in servos etc

Wishing all the best for a succesful maiden

PS. if using the stock ESC, program the PWM to 8Khz. Alot are finding the scorpion prefers this setting

Enjoy

Where did you find linkage length recommendations for the servo to swash rods. I had to do them from scratch. Luckily the the 451's were pretty easy to work with.

I took them from the manual that came with the kit. Does anyone know how far from the bottom frame block the swash should sit? In other words, what is the middle point (in mm from the bottom)?

The guide pin on the swash, when level and at zero pitch, should sit in the middle of the anti-rotation bracket. Just measure it.

Do you have FES or STD version?? I couldnt find anything for it. I just made sure everything was level and parallel and used my digital angle gauge ontop of the blade grip to ensure it was level or close to zero degrees.

I played with the swash for a while and found that 16mm from the CNC block to the bottom of the swash gave me level bottom mixer arms. From there, I just made sure that the top links were long enough to level the top mixer arms. So try 16mm and see how that treats you!

Okay, 16 mm thanks. I have the fb version

I have the flybar as well. How did the 16mm measurement work out for you?
