Just as an FYI, I took a look at 500FL Pro pictures and saw Align has modified the tail drive gearbox and the antirotation bracket for better elevator linkage clearance. I don't see much in the way of the pitch and aileron servo clearance being different as it is still a DS510, but it's a DS510M. So, maybe they're ignoring the slight hit at extremes for these servos as well? :)

Haha! I know you like that idea. :D
You triggered me to look inside the 500EFL manual.
They use the D6FF Metal Servo Horns and tell you to use the most outer hole.
There is no info about how much mm this hole is. :arggg: :arggg:

I asked a fellow freak and will post it here as soon as I know. :thumbup:

Using the outer hole may be because the frames are narrower, but the reality is, the only thing I see less width doing is making the swash to servo geometry a bit odd. I could be wrong, though. The swashplate in the pictures I've seen definitely have balls with standoffs; one larger than the other.

This one from rotaryguy?

The number on the swashplate is completely different I see on my 500ESP swash.
I do see the inner swash has the two shorter balls.
More I can't tell without seeing them next to each other.

Yep. That's the picture. I'm helping a friend build a V2 550 and it has a similar ball/swash setup.

Did you check out the metal servo arms on the 500E? Overkill for a smaller helicopter given the torque needed to move the blades and trouble in hard crashes because the servos can be totally destroyed instead of having a broken arm. In the three years I've had my ESP, I can't tell you how many servo arms I've broken in crashes.

I listed the specs on this product page (http://www.anythingheli.com/align-d6ff-metal-servo-horn-hsp61013-for-ds5-ds6-futaba-600efl-pro-gaui-x5/). My measurements were 18mm and 21mm. I hate that align does not put this info anywhere on there specs so I measured myself and did it for them..

Hope this helps.

Correct sir!! The second hole from the outer most hole. Then put short balls on the inner swash ONLY for the links, NOT the mixing arm links. Sorry for the late reply. I've been out having WAY too much fun with my 500:D

OK, to make sure we talk about at the same thing a picture.
You mean the hole with the arrow?

Yes it helps!
Got the same info from a fellow freak.
Thx.

Good point for not going with the metal arms.

I believe you do! :thumbup:

Align always gives you mm measured from the inside out.
To prevent confusion I wanted to make sure, thx.
You are now on the 16 mm hole.

I think this looks like the best answer to the problem.
Even the metal horns don't have 13 mm holes. (But and 18 mm and 21 mm.)
So, use the 16 mm holes on the plastic horns and the shorter balls on the inner swash ring.

I have to verify this myself but hitting blue/blue on Step J and L must be possible.
Problem now is, this weekend it's great weather in The Netherlands so I follow DVUSHELI and fly the :BSS out of it.
Wrenching we do afterwards. :thumbup:

Please chime in if you have the original Align FBL head and swash and already use the above suggestions. :thumbup:

I'm actually using the KDE head:noteworthy Mixing arm locations are preset, so everything's perfect from the start!!!
If you want the setup right and fast, make the blue light come on, and then set ur cyclic pitch to 6* at the links. That way, there's no second guessing.

I can't believe how much more confidence I've gained since using this system!! All I did yesterday were flips, rolls and tic tocs. It feels like I'm flying the sim, I swear!! I just have to dial the tail in a bit more and it'll be perfect. Too bad there's a hurricane coming tomorrow, so no flying:thumbdown:

Join us overe here, tomorrow we go to the field. :lol:
Perfect flying weather. :YeaBaby:

Edit: be careful with the hurricane, we only see this on TV, it looks horrible.

What I wouldn't give to take trip over to that side! Thanks, hopefully it won't be too serious. Just enough to cancel work on Sunday lol!

So, since weather is bad I started wrenching.

I now switched to the 16 mm hole on the servo arms and used the shorter balls on the inner swash ring.

BANG, blue and blue on Step J and L. :clap

If I measure cyclic pitch it shows me 13* without binding. :thumbup:
That is much better than before.

Weather sucks, so I have to wait before test flying it. :thumbdown:

13* cyclic is alot of pitch:wow2: You'll b running a total of 25*

Test it slowly.

:YeaBaby: I already reduced my ATV's before the first flight.
Otherwise a roll or flip will be a total blur and out of my control.

Weather needs to clear up a bit here first.

OMG, I could not resist and ordered myself a shiny new pair of Align 3G blades. :face
(HD420E)

Let's see how they perform compared to my 425D FB blades.
