View Full Version : I guess you need to loctite the servo arms too...

After upgrading to hyperion servos somehow it slipped my mind that I should put some loctite on the screws that hold the wheel on the servo.

Well that little mistake bit me in the ass today when just testing out the 440mm 600 flybar and stubz paddles.

Luckily I was only about 2 feet off my driveway, when all of a sudden it pitches hard left and back. I instinctively hit TH and watched a chunk of blade go flying off through a fence almost hitting my dog.

Of course it bent the fly bar and nicked up one of the paddles. :mad:

Oh well, I didnt like those blades anyway, but it still sucks, tomorrow is going to be a beautiful day :bawl

This is probably futile, but I'm bored.

Isn't the following easier to read : ?

LOL, NOW there isn't.

The original was all one sentence / paragraph, with no capitilization :

lol marco with your complete mastery of the subleties of the english language i'm surpised you haven't been given a personal commendation, on behalf of all english professors and authors alike.

since that may be a long (and some may say overdue) time coming, then i shall hereby dub thee poet-lauriate of the hurricane 550 forum!! please kneel and take thy sword of verbal masterage upon thine shoulders and stand sir marco of sheep-shaggery.

woah actually... i'll do the honors with you standing up instead. too many puns to be gained from the previous position.

anyways, as poet-lauriate, your official dutie shall henceforth include:
using continuous "stream of thought" technique when posting
delivering complete, complex messages through but a single, unbroken paragraph
taking regular breaks for the consumption of "creativity enhancing miracle plant substances" (or cemps for short)
using your camera phone for the taking of striking and sometimes mysterious pictures
acting on behalf of kiwi-land for the enjoyment, amusement, and complete neural enhancement of your fellow forum members.

however, with great power comes great responsibility, so it shall also be your personal responsibility to use your body to diminish and reduce the damaging effects of the helicopter-vs-ground incidents of your fellows.

and always, always, pass the :smokin:

I have some loctite 661, can I use it anywhere when building the heli for the first time?
I know it's used to bond cylindrical fitting parts, and "holding gears and sprockets onto gearbox shafts and rotors on electric motor shafts."
I got it from a friend's factory.

that sounds like green loctite.. which is good for securing bearing to METAL holders..

buy a bottle of blue loctite.. it doesn't cost much and a little goes a long long long way

It's kinda implicit in what MM said, but I'll say it explicitly - be careful putting any thread lock on things as it can have a strange effect on some plastics. Finless has a video on how to use it (basically use it sparingly and wipe off excess - often better to put into threads with a cocktail stick rather than putting on the outside of things if it could get onto plastics or into bearings etc..)

I managed to get some on the plastic cases of some Hitec HS-45 servos one time - when I went back to them the next week they had all weakened where the loctite was and the case just crumbled away. Fortunately I was able to buy new cases otherwise my clumsiness would have killed 3 almost new servos (at about $25 each)

well, i got her all back together ready to do a test flight after work tomorrow, she is all loctited up and i hope these new blades will be better than the "3D" blades that i had on before, i also put on trex 600 tail fin's since i broke the rear fin in the last incident, i just snapped some pics of her looking good:

oh you're going to looove those blades. i have them on mine and will never buy another blade for my hurri. more pop, way faster cyclic, and good airfoil. you may have to tone down your swash percentages by around 2% if you find it too twitchy. let us know what you think

Be careful.

If the servo output shafts are metal you should be ok using threadlocker, but if they are plastic (like on the 821 servos) don't use threadlocker or it will eat/weaken the plastic output shafts to mush and they will fail.. would just be a matter of time..

I bought (8) 821 servos last year (used) from folks saying that the servos had weak output shafts, kept breaking during flight (some even on the bench during testing).. saying they were junk etc.

After replacing the output shafts on those same servos.. I'm still running em on the hurris. The problem was the previous owners used threadlocker when they put the screws into the output shafts.. which was the cause of the output shaft failures and the the servo arms falling off, not a servo problem..

ya, the servos have metal output shafts, thanks for the tip though
