maybe this in a post from hf user coom in the [Vid] BeastX V3 - Test flight will help with this
"Edit: Oops, it's seem you're right ! The module is limited to 500°s, it was 420°/s before."

times while doing 3D because the tail over rotated. I can live with a little inconsistancy during big piro manuevers, I have a higher tail gear ratio and larger tail blades availible so I may not even run into this inconsistancy issue.

Did you try what I said ? Move your rudder stick in any direction and check the BLUE DEL ! It has to stay "ON", if it goes off (even for just a few moment), then your travel adjust (tail channel, generally the 4th) IS TOO HIGH !
Check for that, I had the same issue on my MBX V2 ! To set it correctly you have to put your rudder stick on the maximum left, then reduce your ATV until the DEL stay ON. Do the same for the right side. Remove 1 or 2 point to make sure that the stick will never go to the point where the DEL is going off (or going to flash). Please, make sure that you check that before searching for anything else.. |

I lowered it 10 points and got it to hold but still wasnt pleased with the piro rate.

I gave it to a friend and bought a Vbar.

blink would you mind updating this thread after you get the vbar dialed and and let us know if the problem went away, just want to see if it does it still

With respect dude, he went over this ground 2 pages ago. I can understand that not everyone wants to read through every post in a long thread, but it's a bit hard on the OP to demand that he accommodate late-comers. The key post in this thread (to me, anyway) if you care is post #12. Chances are that V3 changes this game |

I've seen somes posts like "try with 106% on your ATV", but if I go upper than 83% on my 8FG, I'm in the fast-pirouetting mode, which is not subservied by the gyro. Quote:

I take your point. Evidently, 100 on JR is not 100 on Futaba (and neither may be 100 as far as the Beast is concerned). In which case the only way to go is via setting the ATV on the bench just shy of where the LED goes off. Then, at that point, you get 500*/sec - the fastest piro rate that the Beast will control. Though not even that's assured, see post #12. It's interesting that the otherwise excellent and comprehensive manual is quiet on that rather crucial (IMO) point of calibrating the rudder throws. The note on page 63 will appear rather cryptic to the casual reader. PS: extrapilot, might be worth playing this game on your "asymmetric" rig: does your LED go off at the same ATV, left and right? |

Personally, no. I have 86 (left) and 93%.
Not a good idea to post that here |

Whichever day it ends up being, I'm sure it won't be on one of my days off. I don't usually have that kind of luck.

Mine remains solid blue, I do not even get a blue flashing led at any maximum (full rudder deflection both sides, with full up/down collective, full cyclic) in Normal or Idle-Up modes. Additionally, the data log clearly shows the system is sending a ‘go to neutral’ signal to the servo once 500deg is exceeded. It would not do that in any sort of passthrough “blur” mode, else you would have no control over the rate beyond 500deg via your TX. Mel’s post re: some other FBL unit is incorrect. It may be that they have more margin (i.e. non-blur is limited to 480deg/sec), so that even with FFF piros, the lag in addressing the reversal of relative wind does not push the tail out of the controlled mode. But, due to processing lag, and servo response time, it is physically impossible for a machine at 499deg/sec in FFF to maintain 499deg/sec; the phase lag would amount to something like 25deg rotation before any deviation/correction can even be executed. Regards R

I read your post over in the other thread, and I agree with your analysis. I just find it hard to understand how Blink can find the vbar's piro rate - actively managed well below 500*/sec - adequate yet the Beast's piro rate - once stabilized - too slow. Very odd.
Let's wait for V3 to come out and perhaps you can post the results from that. Cheers. |

Took out the Vbar today, fast piro rate with no issues. Really happy with Vbar!!

Too bad you couldn't do a comparison with V3. But it sounds like you're happy with what you have now, so that's all that really matters. Good luck!

All has changed now !!!
on Microbeast Version 3 the tail can be quite fast and is still able to have fully control on the rate, even under load conditions. The "free wheel mode" is only there for doing some fancy thing like very fast "pin wheels" ... best regards, Walter |
