slop tip for x50e

[audio131]

found a alot of slop in links, traced it to the pitch levers ,the sleeve that the bearing ride on is a bit too long. if u grind it down to be flush with the bearing it will ride fine on the little shim it comes with and the slop is gone..

the washout arms have the same problem.. sleeve too long. arms rock back and forth.. will gind those too.

heli was much better today..slop all about gone. and with align 600d blades it was really good..

In the "dark ages" when I started flying helicopters I learned another build habit to correct this. I developed a habit of using locktite to secure all bearings on their respective shaft. Things that are side-loaded in flight like belt drive tail output shafts I'll use blue locktite, and for most others red. Generally blue is enough everywhere but maybe the pinion support bearing .Only takes a teeny tiny bit to secure the bearing. This removes any slop of the bearing sliding on the shaft, and also ensures that the bearing is secured and never spins on the shaft, wearing a groove in the shaft (don't ask me how I know this happens, learned it in the schluter/Robbe days). The margin for "too tight" or "too loose" is probably in the ten thousandths and freedom of movement is better than absense of slop, so I much prefer the manufacturer to have bearing sleeves a touch too long than a touch too short. I also blue locktite the sleeve onto the bolt that secures it. I've always found that the tolerances in the bolt mean that you usually have to have multiple bolts to find one that fits the tube perfectly without that ten thousandth of freeplay. Locktite eliminates it. This being said, I also do exactly as audio mentions, just a swipe or two with a file on the end usually gets them perfect before the locktite application. You have to decide for yourself if you want to locktite bearings to shafts, as there is a downside. When you need to dissasemble something it makes it more difficult,.. sometimes requiring a bit of heat to loosen the locktite.

no its not the bearings,it was the sleeves too long.probably a prodution over site..... my heli has no pitch slop now... at the same point ive been flying just as long as u.(dark ages)raptors have never been perfect . always took something to modify or upgrade.

[gwright]

I know what you mean, but my point was with the longer tubes the bearings can slide around and with them locktited they don't move, so the end-goal is satisfied.

[audio131]

it flys well now,, i actually like the heli so far.. those plastic bearing block have slop in the can move the bearing back and forth.. im waiting to get the metal ones in the mail,, should fix it.. the gear train is very smooth..

I've been doing that because my 2 JR helis flat say to do it in the instructions. It works,big time. The Vibe NEX they even had me put locktite on the bearing inner/shaft interface in the tail boom, in addition to a cou[ple other key areas. Man does that stuff ever hold on .
GWright ! You have lately, I havve seen personally, offered more valuable advice to more people and then are rewarded with disagreements, dismissals, etc. than anyone I know of just trying to.do a good deed.
I was considering going with a Raptor G4, saw that completely awesome display of that monster doing the slow 3-D thing , getting 10 minute plus flights so I sent this very busy man a PM. I got back several long paragraphs I'll be eternally grateful for, dear readers.
Plus, I bought and copied his set-up except with a Skookum which is all thats left to figure out and away we go.
Sorry for the epic length, I just wanted you to know all you do is appreciated,and valued.
Thank you. Doug
