everything was up to par imo..
the canopy light years ahead of any blade 550 or 600x ,
the alum , does look dull , like its good ole Chinese (mix our own kind of metal) alum , I think if this bird hits the ground hard,
than some alum will bend , but I cannot say that %100 as I never hit the ground with this bird yet.
I look at the Chinese metal like this,,
"its got that metal look , with the plastic breaking point" so I presume some parts will need to be replaced in the event of a hard crash

but what do you expext for $220?
heck me getting 94 3d flights out of it , makes it worth the money imo,

you could always replace the alum with more assault alum for half the cost of a trex and just know that it could bend in a crash , where as a trex might take the hit better and not be so prone to bend so easy,
again I don't know this , but I presume so ,

It's not a revisiting of the tail rotor but if I have to point it out, you obviously don't understand. A lot of
- "i think"
- "not sure"
- "i doubt"

Back in the day, we went by magazine articles written by credible writers. Now you gotta filter all the information.

Let me try to some some light to the situation:
Tail rotor is "all chalked up" ... So the vibration got transmitted elsewhere. Hmmm ... perhaps your tail rotor spindle bolt?!? What do you think you are paying $200 retail for a kit .. (cost $120 or so to make?)

I know the reason why but I'm sure you will not agree with it anyways. Now I have learn to "slowly not to care anymore" .... best of luck

now I get the angle, clone/cheapy takes on the big boys and makes points.

Might want to consider upgrading critical screws for trust worthy supplies, Chinese metallurgy sometimes from poorly refined recycled mix, lot more impurities but who's watching, until something fails. It's like that with low grade supplies costing pennies while higher end processing and refinement costing more, always been that way with cheapness being associated with disposable. One manufacturer took a slam when people complained the screws were like butter (early Sab 380) anyway it's like that with everything.

Nice save! good job keeping your head and getting it on the ground in one piece.

drive a rotary, fly a rotorcraft

did the tail sound like this one?

Watch at YouTube

somethings not right, it shouldn't sound like that. Is the problem anything like the 700e first gen tail failures due to a destructive rpm with main head speed around +2100?

hell no lol

that thing sounds bad !!!!
at first I think the owb let go? I dunno tho .
I do know that thing did not sound good,,
ive done quite a few overspeeds but holy sh*t lol..
I fly at %97 flat curve and mine sounds nothing like that

I really don't belive there was a vib!! how??
my tail fin wasn't vibrating ,,

if there was a vib , wouldn't my tail fin be moving?
the bolt broke on the threads ,, isn't that a classic example of metal failure form stress?

i think the bearing in the grip might have been going out , which is why i no longer have the shield on , and maybe that play caused the failure?
don't know , but i know i did not have a vib, at least not what us humans call a vib? because why wasn't my tail fin moving>? that's why I'm shooting down your tail vib theory ,

explain how i can have an imbalance in the 5000+ rpm tail , but no vibe?

hmm unless maybe he has the stock main gear? that would be loud, but the way he was nailing pos to neg pitch I'm sure that would have stripped it clean?

is that your vid? cuz i dunno why that heli sounds off,
but again , i think in the start of the vid , that the owb slipped?

no it's not my vid, wish I could fly half as good.

cheap kit = cheap fasteners, probably the simplest explanation,

Yes there would be a vibe you wouldn't see obviously if the tail grip bearing on one grip was damaged with a little play as you described, the cog would have offset on the shaft axis ever so slightly. So then if you extend one grip out even a half mm you have the cog offset by 1/4th mm to maintain equilibrium. Try the main gear, is it cnc'd? no? it's not perfectly round either and the loose sections will cause a slowing down of the main shaft and a speeding up into the closely fitting teeth, all happening at the rpm the heli is set to. Using the tail fin as reference for vibes is not absolute. Very high rpm will uncover those inconsistencies quickly and often destructively.

Do you think about the majority of bearing replacement by now also?

I don't think its my main gear, I have the trex slant 112t. its pretty straight to me, infact switching from the stock main gear to the trex made it half as quiet!
I think this kit has both cheap and good bolts, if I remember, my head spindle bolts has a 12.5 grade stamped on it?
so some are good bolts, but some are plain junk, I did a review and pointed out the good and bad ones.

today I am going through the heli , for an official faa report lol

thus far no bearings have slop.. tt bearing good, tailshaft bearings ,, good. main block bearings good, main grip bearings good,

tho only bearings thus far are the tail grip bearings,
I think I'm gonna buy a trex carbon boom, just to add more strength in the whole tail

again I beat the piss out of this heli, and it stood up to all but 100 flights without flying apart,
so any "sunday flyer" would love this heli,
besides who in there right mind would pay $1200 for a sab just for sunday flying?
be smart ,get a model to match your flying , I dunno maybe its just me .

some people wipe there butts , and than take a poop,, I can see some people on here are like that

but no , only the tail needs replaced as far as beaings icanfly,
I think they use decent bearings in this kit,,, I'm pretty sure "atomic skull" confirmed this,,(not sure tho)

I really think you should get one, because once its side by side other helis , you see its right on par,,, only the alum is a bit softer ,
