BeastX issue still there on my 450 pro.

[Lynx.1677]

Guys, I have tried everything and even having the grips the right way round hasn't solved it at all.

I found this vid of my flying my 450 Sport with the Align 3G v2.1 a while ago.

You see the move I do at 0:35 seconds, fast backwards inverted to half piro with two piro's, (I do that before and after too). Well that done at that speed with BeastX causes the head to really bog like mad and generally puts it into a weird orientation and I crash.

So, why is it the seemingly inferior Align 3G unit can cope with such a move and the BeastX can't. I am using the same servo's, same collective pitch same cyclic pitch, same motor, same esc, same blades etc etc.

The issue is either setup or firmware, perhaps both. Now, with the Align 3G I had to get my servo's 10mm in from the centre ball to cure the nod. With the BeastX they are about 14mm from centre to ball as I have no more DS3 servo horns. Perhaps this contributes to the issue somewhat but even when I had the 3g 12.5mm out it was not as bad as the BeastX is on aggressive moves.

Stumped still.

Having seen your other thread, about step L in the setup process, makes me wonder if you have too much cyclic pitch, causing excessive bogging -could that be it? ...have you been flying with 15 degrees cyclic, as mentioned in the other thread, or have you got it lower than that?

Got to be worth trying to get hold of some shorter servo horns as well and seeing if that helps.

Also, at point J, you DID get the blue light right?

there were a couple of really good setup videos floating around. Looking at the move you do its very harsh on the model and pushing the aerodynamic limit. If you have the setup wrong it will definitely over pitch it and do all sorts of nasty stuff.

The beastx dosn't work aswell as the 3G on 500 size & up" now I've beast to of my 450 size heli's 450pro & Mini-T & have noticed a big difference between them.
When I first done the pro I thought is was really good but in ya mind you know it's not right, Mini-T confirmed that"
When I first mod the MT it flew just like the pro but when coming out of some 3d stuff I'd suddenly loose it"
I found a spare Blade 400 swash plate smaller than the align which was also part of the mod on my MT, having mod my MT with swash, took for test flight yesterday morning & can't believe the difference in her all problems solved done 6 lipo, then flew the pro one pack & gave up.
I think the problem is swash size so I'm now going to mod my pro with smaller swash.

Yes, blue light, 6 degrees works out fine at this point.

Interesting about the smaller swash size! Would love to know the science behind it and if it is indeed the only cure.

The swash' lower disc can be same size (Align) but upper disc needs to be smaller, the swash balls of your Align will screw onto the Blade 400 swash & for 13 quid worth giving it a go' as I will be this week ready for weekend, I'll be happy if I can get it to fly same as my MT!!!
My 250 beast also flys just like the MT so I'll update you once I've done it".

I honestly think I have got to the bottom of the issue. That issue is firmware. When doing these aggressive moves, the beastx is giving extra commands that do not come from the user. This happens when you use a lot of cyclic and rudder when loading the head.

A guy who shall remain anonymous wrote to me.......

"The BeastX has some issues with regards to piroing and cyclic input - The more Cyclic the more severe the effect, the effect being the model would do something un-commanded. Now I think this could be the issue with you. Putting fast large cyclic inputs in and the BeastX gets a bit confused and does something uncommanded..

Luckily this is fixable with a firmware update..

They know about the issue, but do not seem to care.. i quote

"Yeah they know, i even talked to main guy in germany, they kind of hated me because i spoke badly about their product, be it was he who called me at least.
(after that i gave up on all threads which turns into which system), i only post in those i cn give a clear answer how to fix a thing"


After that i have spoken to several "pro" who experienced same thing, its only for us who do advanced piro moves, thats why you dont hear more about it.

I suspect when PC software comes out you will have better way to tweak it."

[shikari_chaos]

Well update it already! lol
Hopefully they'll bring out the fix in the next firmware yeah!!
Glad to see at least they know that there is an issue and it can be sorted in the firmware. and yes lets hope the PC software gives you that flexibility to solve any niggles one may face

Let's hope so. For now though I am selling the BeastX unit and going down the miniVbar route. And if that doesn't work I am going to sell everything heli related for 15pence.

If the outer swash balls (going to the servos) stay at the same diameter and the inner swash balls (going up to the head) are at a smaller diameter then you are getting less pitch change for a given amount of servo travel so wouldn't this have a very similar effect to putting shorter servo horns on the heli? Interesting, as Lynx.1677 has already highlighted the long servo horns as a possible supect.

+1 as above

Because I was having problem when flying my MT with the Align swash I put it down to poss when I went through the beast setup I couldn't get the 6 degree! even by moving ball links along the servo horns so I fitted the smaller swash which allowed me to get the 6% regulation bang on, I do know that when I setup my 450pro I could only get as near as 7% (blue) & that ment moving the balls on the servo horns so I'd be supprised if someone else can' so that's why I'm going try smaller swash on the pro.

I tried setting up adjustment L to almost the lowest setting which was red. The strange thing is I noticed no difference in flight at all. I then put it to all the way upto max again and it flew the same.

So, onto the next thing. Adjustment via radio. I was just about to try it when I herd of disgruntled cows showed up so I legged it. Last time they cornered me I left my starter in the field and they slobbered all over it.

Its the 'regulation' 'J' I was referring to' on my pro can't get it to go blue @ 6 degrees whereas my MT with the smaller swash plate can get 6% @ blue, pro won't allow me" can only get blue @ 8% just under which could count for it's behaviour so I need to try the smaller swash just to satisfy my own thoughts.
