What I would do just to have tried it, is to experiment a little with servohorn distance. Yes you want to have 90degree movement deflection, but you never know if mechanical gain is somewhat off compared to the electronic gain, if you follow my drift.
Some tailservos has such good resolution, that you can in fact go out on the servohorn without suffering anything from it. Also in the past some gyros like to work in a particular set "limit values". Cant say I have noticed that on the beasX, but you never know ^^

the slop in the tail grips is gone. test flew today but the wag is there and seemed more prominate. im gonna fly it as is till mon or tue when my 7200bx gets here. im droping the beast and rx for cleaner install. after that prolly do the bearings and hope for the best.im also gonna try mocing the ball in on the tail servo. currently its at 15mm out on the DS650

Maybe that might be a little too far out. I'm at no more than 13mm on the 550. Can't be more accurate than that as it is difficult to get under there to measure. On the 600 I am only at 11mm. There was no science behind where I have them, other than it is where I just put them to begin with, and since I have had no tail issues on either one, I have just left them there. Both have 650s too. Even on that very small sample of two of my helis it has to be worth trying coming in a hole. I know you are going to do, but I just thought I would re-inforce its worth in trying it.
Good luck. Cheers Sutty EDIT: No, they are both 620s, which I suppose changes things, but perhaps still worth a try.

Today I did some more flights after tuning my tail with the new V3 guide.
With Parameter D (tail headinglock gain) on very high (blue), Parameter F (revomix) off. When doing FFF the tail suddenly starts to wag violently. Landed safely and went back with Parameter D to high (blue flashing). This solved the violent wag. Maybe I could also solved it by lowering gyro gain. What is the proper way? Lower gyro gain or lower Parameter D? I was not sure about what the side effects could be from upping Parameter D, but for me it's violent wag. (Only seen when in FFF.) Is this "normal" and to be expected if you run Parameter D at a higher setting? All this tested on my Gaui X5. Thx!

Yes too high can Parameter D can definitely cause that. Probably a combination of the main gain and Parameter D too high though.

Could Dial 3 be of any importance here? I guess not and because that is already tuned perfectly I left it alone. My gyro gain is also close to perfect so in this case I backed off on Parameter D one LED.

Nope, Dial#3 won't play a role although it can cause some issues if you turn it up too high without having the other gains optimized already. Sounds like you're on track!

Yep, I feel the same, thx.
With my limited skills (no 3D) it's hard to decide what's better. A bit User defined revomix and Parameter D on medium (red) or revomix off and Parameter D on high (blue flashing.) I guess keep on flying and improve my skills.

Just wanted to say "Thanks" to you, Bob, Sutty, and all the HF's contributing to this forum. Did my maiden today on my X50Titan TT which was totally awesome. I'm a first time BeastX user, having a Trex550E with MiniVbar. MB setup was a breeze thanks to all the great setup tips, suggestions and videos. Your Tuning Guide was fantastic! You guys ROCK!!!!!

update. TT X50 torque tube : so i got the tail issues worked out. it was a mix of repacking the thrust bearings in the grip along with a proper mechanical tail setup and i had some binding in the swash. the bottom of my ele arm was bottoming out on the one way bearing on the main gear. all resolved now and flying solid.
TT X50 belt : I replaced my beast with 72BX and setup is going well. on the cyclic pitch geometry i get blue light at 6.5 degrees. should i leave it at 6.5 deg blue or 6 deg red? how does this setting affect flight characteristics?

You have set it up incorrectly and should change it. Blue at 6.5 is not the goal. 6 degrees is the goal, and the colour merely an indication to you as to how optimal your heli is suited to FBL control. Red will be absolutely fine. This has been well covered and is as described in the manual. Sure if you get purple or off when you set it to 6 degrees then you should probably look to change something, but red, no problem at all. All of my helis have been flown in the red at some point, and I could not tell the difference when I changed various things to get it to blue. My 550 is red right now, and flies brilliantly.
Cheers Sutty

7200bx setup menu G
At menu G all the servos are even. All my links are dead on even in length. After i leave the setup menu and move the collective pitch full up my pitch servo is lower then the rest. When i go full negative, my ele servo is lower then the rest. This is all done with a swash lvl tool. What gives?

After you leave the setup menu the controller takes control and the gyros are active. Measuring any sort of pitch, swash level, cyclic pitch, etc. is futile and inaccurate. You have to be in Setup Menu G with any color light on to check swash level. The BeastX does not have a menu for leveling the swash at high and low. Honestly, mine all punch out dead straight so I see no need for it.

+1, mine too. I look at it this way, there is probably a reason that the team at BeastX didn't bother to implement high and low levelling, and that reason is simply that it doesn't matter. I imagine it isn't too difficult to do, and they may do it in future, but I don't think it will change things much.
There are so many other things going on during a full push on the collective for a rapid climb, such as differences in servo torque and speed, differing amounts of slop, weather conditions, etc, that the MB will be working full time to keep it straight anyway. Since it has all this to do anyway, working a little harder as a result of the travel extents being different, probably doesn't make a scrap of difference. By the way, and this is a little embarrassing, but I will admit it here, just to prove the point. I had a minor mishap with the 250 over the weekend, and I lost a set of servo gears. I fixed up that servo by replacing the gears, and thought I had centred the arm, after re-building it, but I didn't check it. So, on doing my test flight, I thought, wow, the collective seems low, how can this have changed so much. I did a full +ve climb out to test, and it just gently went up, at about 1/3rd of its normal climb rate, but perfectly straight still. What's up with that. Brought it back down, and as I did so I realised what I had probably done, so I went into G to check it out. The repaired aileron servo was so far out I couldn't believe it. It was a quarter of the way around, when meant to be level at G with a light on, and yet, it still flew level, and climbed straight, just slowly, lol. Anyway, point being, even if you are out by 30 degrees, not .5, or 1 degree, the MB still somehow manages to keeps things straight during a climb. To fix it of course, I put the light off in G, positioned it close, switched to that servo, eyeballed and adjusted for square, exited set-up, went outside to test. Perfect, back to normal after two minutes or less of messing. Shows how good it does its job. Cheers Sutty
