BeastX Knife Edge piro Problem

[waveydavey]

Cheers Lee, really appreciate that. I've just checked again and I'm 10mm out on the servo horn with the standard Outrage 95mm blades and a headspeed of 2150. My Tx gain is around 48. I hope it doesn't do it because you'll get a bit unnerved by it, so plenty of heigth mate.

Be interesting as i know the tail geometery isnt great on the standard velo, which they now fixed on the N2 and fusion, im not easily unerved mate lol, maybe try some different tails? Also try it into wind and down wind with left and right tail, it should be better left tail down wind if its the servo, if its the unit itll do it whatever

Hi Lee, I've seen you fly so I know it's in good hands. It is odd when it happens though. I was into wind and didn't try right as they had tried that earlier on the other machine and nothing happens, IE it doesn't piro. I was giving left stick

If its an issue with a combination of controls involving roll followed by rudder, then it should. E reproduce able. Y roping and then pirouetting I any attitude, or maybe even on the ground with the Heli stopped. I've not seen this on my 500(bx v3 with 520) or my 600n (bx v3 bls251).
If its mechanical then t should be possible to see it from ff fight just with a pirouette.

I impressed with the tail control on both my beastx helis!

My tx fans are at higher like 85% on the 500

Lol your one of the priviledged few as i dont do much anymore, it does sound like a weird problem your having, maybe just the unit, and the seperate beast may not do it

I never thought of trying it on the bench, would the fact that it's not moving stop any useful results

If it's the servo why would a 650 and a V Bar be okay.

Dave am I missing some logic here or is your thinking that you might have to off the beastx to cure this phenomena?

If two models exhibit the same behaviour using the same combination doesn't that make it more likely to be the combination or one of the components being used? So afterall it could be the servo is not upto the job or the beastx is not upto the job?

[waveydavey]

Either one really Andy. The odd thing is that Andy's with the 650 on the tail and the V Bar is fine. I don't know if you remember Josh's Logo exhibiting the same thing, but the same results. As for offing the Beast, I firmly believe it should be able to cope with my ham fisted attempts, it's as if the command is input, nothing happens, the Beast recognises this and then over does the rudder input. It may be totally down to the servo, but across 2 machines.

The one and only complaint I ever had with the BeastX was the tail Dave.

Sorry I cannot give you any advise on the problem but I had the very same isues when I was running them, inconsistant piro's.

I had Align ds650 and Futaba BLS251 tail servo's and both suffered the same.

I cured it by fitting a CSM 720 alongside the BeastX and since moved on to the V-Bar.

That is my point. If the beastx is upto the job then the fact that both machines do the same thing points to the servo. Leave everything as it is and get a different make or model of servo on there for a trial is my first suggestion.

After setting up one of these machines and seeing Daves model yesterday, I think the tail
dynamics function is were the problem lies. Model 1 set up by myself had a fantastic tail when the tail dynamics were turned up. It was only when the knife edge piro was tried the problem occurred.this pot is now turned down and the tail now behaves itself. Now when I set this pot I found that in turning up I was able to improve the tails piro consistency and get a vbar like feel. Maybee we have found the limits of the beastx tail.
As suggested in an earlier post, my next tests would be shorter servo arms with higher tail gains.

It gets even more bizarre, not even a 600 fitted with the original BeastX V3.08 will knife edge piro. Fitted with different servos they just won't go round. You can tease it round with slow application of rudder but V bar equipped helis have no problem. Anyone any ideas

I should be flying my beasted velo 50 tomorrow, so ill try it and report back, got me worried now as i like to stick knife edge piros in going through moves, it could go all wrong lol

[waveydavey]

It's not just the BeastX, V bar also on a Fusion. If you feed tail in slowly not a big handful as if you're trying to get the piro over and done with it will go round. But, if you stick full rudder in they go nowhere. We're thinking that knife edge the tail is effectively the elevator and is working really hard and hasn't got anything left to give. Or, the attitude is giving the unit a bit of a headache trying to work out why anyone would want to piroette in that position

Hi Dvae.

On the beast can you adjust the rudder lock gain value? If so could this be too high and be keeping to much of a hold on the tail rotor.
