help protos 500

[victor gomez07]

hello friend need your great help and I am very desperate and can not do with my protos 500

what happens is the following

once the engine accelerated to more than 80% the blade grips Rear not working properly no runs to end

as if it got caught and could not serrvo tail with the inertia of the blade grips

and remove blade grips and so it works properly

and change blade grips

any ideas

[Hankstone]

are you saying the blades don't spin or do you lose pitch control?

lose pitch control

no slides to either extreme, with high rpm
Thank you

[Hankstone]

Does everything move super smooth and buttery? Pull the fork deal off the slider and feel the slider on its own. Is it as smooth all the way through as it can be? If not get fine steel wool and polish the part of the shaft that the slider moves on. If it's great but when u put the fork back on (can't remember the name of that part) it's sticking then u need to check alignment and relieve the binding. Or buy a linx tail lol

Check the grip assembly as well... is it correct?

thank you very much friend, if it moves properly without snagging, the problem comes with high speed, it appears as if the tail servo does not have the strength to move the blade grips until the end of the tour

Thank you very much Greetings

What is your tail servo. Without tail blades on, nearly any servo should be strong enough to move the grips

so it is if I remove the grips tail if you make your work corrrectamente
} is the place I return to again and do the same strange thing is that already bearing change and nothing changes

tail servo is

MKS DS-8910A+ Titanium Gear High

[jmtyndall]

That's a very good tail servo. I guess you could try another in case yours is bad.

The 8910 should be plenty strong enough if your tail mechanics are smooth

Yeah, maybe the tail shaft alignment is off during higher load / rpm and causing binding in the slider mechanism. I would check the tail case/shaft bearings for wear. Sometimes these bearings can wear out after 40-50 flights. Also I've had some tolerance issues with new pitch sliders and the fit is too tight. This has required using 600 and 1000 grit sandpaper wrapped around a hex driver shaft to slightly enlarge and deburr the opening in the brass slider.

thank you very much will try to change the axis, this does not have to be changed if it improves, also will try again to change bearings blade grips and if not I'm really desperate and do not know what might be happening,
this problem is not possible to fly
thanks and regards

What FBL are you running?

flybarless is my IKON
and change the grip tail with their bearings and follow the problem seems to already high speed servo can not follow it to the end of the tour
I still have the problem please help bring me crazy
They believe the solution is to place a standart size servo

[flint723]

I agree with trying a standard size tail servo. The Protos 500 tail seems to work much better with a servo that has 4-5kg of torque.

thanks friend I will try because I had a Futaba s9275 and 8910 mks torque 2kg and can not seem to

You said it works after you remove the tail grips. What about when you remove only the tail blades?

I'm interested in this problem. Keep us updated please.

If I remove the tail grips tour regulate ago but I return to tour takes place and not at the end of the limits all without the blades

[babyuh1]

Check the spacing of the grips. They might be binding the bearings.
Is this the thrust bearing tail?

hello friend is the original bearings, the servo is a mks 8910 and can not seem to make your journey with high speed as if he were pushing force

I would recommend you upgrade your tail grips to the "thrusted tail rotor":

I had a similar situation with a recently built kit (in the last two months). Once I installed the thrust bearing equipped tail rotor, everything worked well.
