Hello there
Do any of you experience changes in your heli after a few flights?
I find once I get my heli dialed in, a few flights later I'm having to adjust a fly bar after a stall turn of hearing a strange noise in the tail rotor drive system. Does any one experience this?
Let me know please
Thanks

I don't adjust anything until I have a crash, no maintenence really to speak of other then the usuals of any other heli such as lubrication when nescessary and inspections.

Hello
I'd have to adjust the tail rotor belt because it has run a little lack
Sometimes have to adjust the flybar because it has shifted in a stall turn. Tighten up engine screws although there are two lock washers installed. tighten up a screw or two on the mainframe,sometimes the skids. That sort of thing.
Thanks

Adjusting...

if you build the heli right and use loctite in the appropriate places you should have service free flying for a LONG time....

once a machine is dialed in it shouldn't have to be touched at all...unless you crash like OICU812 said

Hi Shawn,
Well, Unfortunately thats not been my experience.
I flew 5 packs this afternoon. The tail rotor belt shifted somewhat.
Not sure what is causing it to move. Bob at esprit said he was experiencing the same thing and he used a set screw in the tail boom to stop it from moving. I'll check mine later this evening and see if it is really moving from the mainframe side or the tail rotor side.
I also have issues with the engine mount screws running slack.
Have you or any one else experienced this. I've had to tighten mine so frequently that I have had to change out a set because I rung the head.
Would also like a better quality screw there, perhaps stainless steel.
Thanks

Well I have no reason to lie, I have not had these issues. In regards to the paddles, have you wicked in a small amount of thin ca when you turned them on and let to set? If not then this would be reason for them backing off or changing angle in hard turns. I just got back from an event where my flybar 6003D was flown by myself and 3 other top rated CDN pilots, "not me, lol" and the helis did not flinch on any mechanics. In regards to the tail I still have yet to ever see the tail box move in any fashion, once it is snug it is snug, I have no setscrews or additional parts to keep it aligned in any way. In regards to your motor plate, did you use loctite on your bolts going into the motor plate? To me this sounds like you have not, I have never seen or heard of anyone else here having this issue and there are over 10 Logos locally other than mine, blue loctite at a minimum for all bolts without the nyloc nuts.

I have had over 50 flights in the last few weeks on my L600 3D and nothing has moved yet. It all seems VERY solid.

Hey Shawn
Ill try the locktite on the engine mount screws. I used locktite on the vblade set screws not the cage that locks the fly bar with the 2mm nuts. I'll try some locktite there. What do you recommend for the tail rotor. I can actually see where it does not sit well on the drive pulley now. Strange. but this is so.
How was the fun fly for you?
regards

ANy bolt that goes into metal should have blue loctite minimum, with this or any heli period. Any bolt that goes into plastic can be helped by the smallest amount of ca on the threads. Do not use loctite however in plastic, only metal of course. As stated there is no modification needed on the L600 tail case in regards to shifting or movement. Unless of course you overtightened the clamps at one point and they are not offering a tight grip no more? In such case than you may consider a packing tape under the clamps, wrap around boom once or twice to increase the OD. I have not seen or had to do this on this heli, only guessing here as I have not seen or had this issue you speak of but it should work for you. Funfly was good, got in late last night very exhausted, long drive indeed.

What about L500? I am about to build one and read a few instances of boom slipping? People recommend tape being needed?

The 500 has "half moons" on the inside of the case, if you over tighten the case on the 500 people have cracked the half moons and seen slipping. In order to avoide this do not overtighten, you can also if you care to use a small self tapping screw on the side to reatin the position of the 500 case "if you feel so for your own". The tail cases for the 500 and 600 are entirely different BTW.

Just make sure the adapters for the boom are seated well as well as the frames and tighten it up. It should not slip at all.....Ron

Also Bob at the freak as you know has a 500 Logo build video full of tips, I suggest if you have any questions, watching this may save you those questions as I assisted him on the video, cheers.

It took a bit of fiddling to get my L500 boom clamps to fit nicely inside the frames. It's tricky because the clamps are designed to be slightly to small to make sure that everything is really snug and holds well when it's all bolted up.
As with most things on helis where there is more than one bolt holding something make sure that you tighten evenly. I usually do two turns, then move diagonally to the opposite screw, then to another and to it's opposite. Sure, it takes a while, but you need to take your time and make sure you get it right.

Sounds like your rocking a high frequency vibration from a slightly out of balance motor or something.
