I just finish hooking up all the electronics, and perform most of the setup within the BeastX. The next stage will be to put on the FBL head and then adjust the swash travel, collective pitch and cyclic range. I will keep everyone updated.

Nice! Is the FBL metal head going into that?!

Just flew my SDX with FBL today, the Beastx is awesome! The preset "pro" setting fits my flying style. BTW, it flies superb with EDGE 603mm FBL blades

Rudy, it may just be the photo, but the wires entering the Beastx can not be tied down to tight so close to the gyro.

Tom,

I probably need to rework the wiring layout as it looks bulky and you are right, I think it is a bit too tight.

rudyy: try this sir, it works fine even with the nylon tie near the MB unit.

Head setup
I have just completed the setup as per Dr. Ben's instructions (Ref: https://rc.runryder.com/t641322p1/)

I am using the Outrage washout base with the modified Evo50 arms/SDX V-links. I am running 88.78mm rod from the swashdriver to the blade grip arm to achieve zero pitch.

For the swash driver arms (modified Evo50 arms), I am using an M3 ball with a conical base for the rod.

Rudy,

That should work fine. Note that you have the rods going up to the head is a mirror image to the way I did it. I can't see where it matters, but make sure you adjust the ball positions on the mixers to get the throws in whatever sweet spot range the BeastX prefers. That's the single greatest benefit of doing it this way. No compromise ever needed on the travel.

Dr. Ben,

It should work ok. The only thing left is just the test flight. I will be out of town tomorrow for two weeks. So, I will try it out when I come back. Now, I have converted both the 600N and SDX to FBL. I should be able to tell the difference between them.

1st Test Flight
I did a test flight a week ago before going out of town, and I immediately noticed something was not right. Further bench test revealed that any elevator input would trigger the swash verical movement. I went through the BeastX setup again and discovered that there were two 140CCPM swash options. So, I picked the other one and the interaction was gone.

Now here comes the cyclic geometry problem. I am no longer able to achieve the 6 degree optimal FBL setting. After talking to Dr Ben, he advised me to adjust the Hiller Bell mixing arm ratio (ref: So what do all those holes on my FZ-5, SZ-5, or SSZ-IV/V's mixers adjust????) as opposed to using the servo horn inner holes for decreasing the resolution.

I will try that and keep everyone updated.

Let me clarify a point here. When excessive travel is present in a system, it will become necessary to go in on a servo wheel to reduce travel because the mixers will only allow travel to be cut by so much. Typically the limit on going in on the wheels will be 10mm radius, becomes you begin to get into pretty serious issues of differentail travel if you swing the ball but so far off centerline with a combination of collective plus cyclic input. For this kind of set up, the servo wheel radius needs to be in the ballpark, and then the mixers will get you all the way to home plate.

I suggested that Rudy use the mixers because his ball positions were right in the middle of the adjustment range. There was lots of room left to optimize the system.

Dr. Ben,

I look at the pics from Piyaphan1 above, he is using a smaller servo horn (equivalent to using inner servo holes) instead. His setup does not have the mixing arm that allows such the adjustment I am going to make.

So what is the advantage of adjusting the mixing arm over using a small servo horn/inner holes?

Hi Rudyy, am using set-up similar to piyaphan1's (direct swash to grip) and the Beastx system. With 12.5mm on the circular servo horns I can manage to get the 6deg cyclic requirement of the Microbeast. I get +/-15deg pitch and the system flies well (extreme mode) and am currently testing the TX mode to try achieve faster roll/flip rates.

I considered Dr. Ben's set-up before since it offers more set-up options/tunability and relieves stress on the 2mm rod I'm using, but I figured I'm not up to the task of finely tuning it (read- lazy) the way Dr. Ben did . If in any case I do have time and passion to do it again I would rather like that indirect set-up with the mixing arm still on compared to going direct. I think I'll do that mixing arm on with my Eagle3 for FAI flying this time with the CGY750

Hi Lewd Skywalker, I think the main blade grip in direct setup is more vulnerable to damage in the event of a crash due to the long standoff protruded outward perpendicularly.

Rudy,

Adjusting on the mixing arms allows a finer increment of change versus changing the wheel radii. It also takes me hours to precisely level and track the swash and set up all the compensation mixers, and all that work has to be retweaked when I change the servo wheel radii.

FBL Update
I move the swash driiver linkage rod to the innermost hole on the mixing aem lever and reconfig the BeastX setup. Voila! It now flies perfectly. I do not see the point I will change my SDX back to FB at this point.

hi rudyy

how are you liking the beastx? i've been flying it on my SDX for about a month now and still minor issues with the tail. i prefer the way the Futaba GY520 holds.

overall it's great going FBL on the SDX, perceived more power and agility

Lewd Skywalker,

After the FBL conversion, I like it more and more. It has a lot more cyclic response than it used to be in FB and it tracks a lot better in windy condition. The FBL conversion has improved the efficiency a lot on the head. One extra thing I do is that I extend the travel of the stock plastic CCPM pin stay by about 10mm to give more throws on the extreme ends and avoid binding. If $$ is allowed, I will go for the blue metal elevator arm.


Where is the flybar?
