All over the place for height in hover???

[banditpowdercoat]

Yeahh That's better. 0,18,50,82,100 for Pitch curve. A little more twitchy in hover but way less stick movement needed to control hover.

Now we know the fix, any Idea why it's like that compared to my other heli? Need more input to get movement due to Protos weight/inertia? I've never flow a different 500 or larger only the B400 and protos.
I'm a physics kinda guy and need to know why and how it works.

0,18,50,82,100??? That's a wacked pitch curve. Why not run a straight pitch curve?

Because of me height stability problem. With straight curve, a lot more collective input is needed to correct for heli movement, or get heli to move, when in a hover. Now, It's a slight movement of stick and the heli responds. It was almost like, with a straight curve, there was EXPO on my collective. But the Dx6i has no collective expo. The Heli now feels more linear in collective.
BX is in transmitter mode too, so no Pre programmed Expo there
Also notices the V3.0.8 BX initilizes faster than the V3.0.0.

I did not read all this thread but check your transmiter potensiometers and see on screen display if you get erratic movement on your pitch curve graph maybe it could be a bad potensiometer that is causing all this pitch problems you are having. There was a recall on the dx6 transmiters having bad potensiometers.

That's all fine, and it doesnt do it with my other heli's. But thx

Something sounds messed up in your setup if you need to run that pitch setup, no one needs to run that on any heli to get response.

I'd suggest setting a straight pitch curve and re-setting the 6 degrees of pitch on the BeastX.

I think that this is all a feel thing when flying. I had to go the other way with my pitch curve, flattening it out in the middle to make it less responsive in hover.
To each there own. There's nothing wrong with your curve if you like it!

+1. I fly a similar curve on the mcpx to give it more pop. Rumor has it the new BX firmare will have some sort of pitch acceleration option that will help with rapid pitch changes.

BeastX already has pitch pump in 3.0.8. It's been out for quite awhile.

I run linear pitch curves and flat throttle curves.. and my baby jus sits there.. never had that problem you are describing.. but if you like it I love it.. but it does sound like something else is goin on.

[Dazhim]

Question... In your beast x there is a parameter. I believe E, that tightens the deadband in the center stick potion.. what is yours set at.. purple I assume is the tightest and the beastx will respond sooner to collective around this point. I played around with it and purple is a lil to squirrelly for me.. and blue kinda feels like a giant SR I settled on red flashing..

[banditpowdercoat]

Not a deadband issue as my other BX heli's work fine off this radio and deadbands all default on them all. It's not at mid stick is the issue but at hover pitch, about 5/8 stick or so. I'm thinking it's because I have the wrong washers in my FBL blade grip balls, spacing them out farther, making less pitch travel around center. My FBL head kit did not have the proper washer, I just learned yesterday what the proper washers are and have ordered more balls, Hopefully they come with washers this time

[banditpowdercoat]

OK, so anyone following this thread, or experiencing the same, I have found the problem, and it is confirmed by Corrado, maker of the Protos

My head(heli was used) had no washer between the thrust bearing and outer main bearing. MSH50135 This will cause the slight servo movements to be sticky feeling where large movements overcome this. Corrado states there is hundreds of Lbs force on the thrust bearing at 2500-2800 RPM I run 2750, so without the washer, it will bind, where when pulling on grips with your arms, it will feel smooth,as mine does

I only had one washer form a old broken tail assy, Same washer on either side of spindle. just replacing one washer made a dramatic improvement. I can't wait to get both in there.

thank you all for your help

I can't belive I missed that washer, been thorugh the manual like a 100 times now

[Dazhim]

Good deal.. let us know what happens when you take her back out.. I bought mine used to.. but had to do a rekit and I think she flies great.. got enuff time for a pack or two so I'm out the door.. b back n a bit(park across the street) Hey let me know how your beastx settings are diff. from mine I'm willing to experiment a lil..

[banditpowdercoat]

Yes, for sure. Just flew my Protos and the Blade. It pains me to say it but the blade flys better. Stops on a dime, flips nicely, I can flip 4' off deck. The Blade is far from stock tho. Only thing protos does better is stationary Piro's and punchouts. Man the protos got some power. Blade drifts on hover Piros n scares me
maybe I am more confidant with the blade, I dunno, I love the protos soo tho. I set it on my counter and catch myself just staring at it endlessly.

I'll get the BX settings later tonight and post a BX/Protos setting thread

[banditpowdercoat]

OK, Put on a new head bearings with the .2mm shims, MUCH BETTER
Reset to linear pitch curve and she hovers like a dream now. Guess the grips were binding due to the lack of the .2mm shim. The shim makes it so the inner race of the bearing pushes on the thrust, not both races at the same time
