... spero si parli di qualche decimo

Beh, 4 decimi (quanto ne ha limato firedragon) non sono pochini...

[EDIT]
Comunque ho controllato il mio in questo momentoe potrei valutare il lasco in meno di un decimo, è proprio infinitesimale.
@firedragon:
sicuro non ti stia partendo qualche cuscinetto?

Issues and Modifications

Early reports have indicated a few areas to watch:

Teathering the blae grips and top links
The screw in the feathering shaft end has been loose in a few cases, leading to some side-to-side slop on the blade grips. Some people haven't noticed this, and the screw has come undone in flight, leading the blades flying off. Ensure this screw is tight and consider a drop of locktight. (Only the end with the cross-head is a screw, the other end is just sloted so you can hold it still while turning the screw)
The bearings in the blade grips have failed in a number of cases. They are 4mm outside diameter x 1.5mm ID x 1.2mm thick (Type: 681X) Similar bearings are used in the TRex250 washout arms. It's not clear which way around the bearings should be fitted, or if it makes a difference. Some people have teathered their blades, which should reduce the risk of injury.
Both of these issues could result in the blades flying off at high speed and these blades are going fast enough to draw blood if they hit you. Wear eye protection when flying indoors.
The main gear is only a pushfit on the main shaft, and can work loose in a crash. To check it twist the blade grips slightly and see if the main gear moves. If so hold the top of the main shaft and push up on the main gear with two thumbs towards the center of the main gear. Be careful not to break the main gear but it will sometimes take a little effort to push. It only takes 5 seconds to do. You will notice immediately if you try to fly with the main gear pushed down a little as you will have a lot less positive pitch.

Teathering the top links
The links between the swashplate and blade grips can fly off in a crash and are easily lost. There are spares in the box, but you could teather them with strong thread or dental floss.
Some helis have the servo links set too short, giving lots of negative pitch. Swing the blades so the tips are togther and adjust the servo links until the blades tips are the same height when the collective stick is in the middle.
The motor has strong 'cogging' making it much harder to turn by hand than the mSR and mCX. It also doesn't start turning until about 1/4 to 1/2 throttle. This is normal and not a problem - although it may worry people who are not used to it.
The feathering shaft from the Walkera 4#6 is the same size, and cheaper (but doesn't come with the washers, dampers and bearings)
Poor collective management can overpower the tail. It is possible to fit the larger tail from the Walkera 4#6 but this adds extra weight and is not really necessary.
The linear servos jitter slightly at rest. This is normal.

Horizon Hobby response to Bearing Failure reports
The following annoucement was posted to Horizon's German site (Google translation, with a few manual improvements)
Dear Blade Enthusiast!
The company Horizon Hobby has this week to the Blade mCP X to the market, certainly the most innovative platform in its class. The Hubscvhrauber is a fully functional CCPM helicopter Flybarless and is therefore to be considered as a performance helicopters. For this reason, we have a service bulletin pointed out that these helicopters are operated with the same care needs, such as a 700 helicopter. With these security measures, a sound and safe operation is ensured at all times.
Since the appearance once again play a role in the forums with an attempt by the helicopter targeted rumors and false information to discredit. It turns out that members have to submit comments on the operation and safety of the helicopter without such or to have ever flown. Obviously, this is the typical reaction from the forums, but have little in common with reality.
It is written, that there are problems with blade holders and bearings. We have checked those comments and unfortunately could not find those problems, neither in our lab in the US, nor in our service station in Germany, nor in our manufacturing facility in China
We have a tensile test performed on the rotor with a load of 35kg and could pull off the blade grip in any case of the camps. In flight, in accordance with existing calculations the maximum tensile is 3kg. We want to ignore the two cases, not known to us, are they investigate further, because the time is unclear whether the helicopter in question previously had a crash and so a base damage as a result of that could be developed. There are scattered wild theories that claim that the bearings have been installed incorrectly. These theories are groundless.
The Blade mCP X has been developed to the best of my knowledge and belief of Horizon and represents the state of the art dar. There is certainly no unsafe product, and the pilot is much enjoyment, when operated with due caution.

mezzo decimo a volta con lima diamantata.... quello e per il mio...

cuscineti buoni ...1.5x4x2 (MS) Bearing (x1) 681xzz [1.5x4x2] - £0.75 : RCbearings.co.uk, For a friction free RC!

Altra cosa che mi piace poco: ha lo stesso motore di coda dell'msr, o lo si rinforza con un po' di termoretraibile o dopo due schianti si apre come una cozza...

Comunque vedo che ci state già studiando sopra, tempo una settimana e vediamo a chi è rimasto un pezzo originale...

Io non so se è proprio lo stesso motore. Nei miei esperimenti con l'mSR ho scoperto che i motori del Blade mCX2 sviluppano molti più giri per volt rispetto a quello di coda dell'mSR. Magari hanno usato lo stesso motore del BmCX2, altrimenti ci hanno lasciato un buon margine di miglioramento sul motore di coda

Il cuscinetto che hai linkato non dovrebbe andare bene. Nel post di fulvico con la citazione in inglese, le misure riportate per il cuscinetto indicano uno spessore di 1,2 mm, mentre quello linkato è spesso 2 mm.

infinity · 13 marzo 11, 13:39

ho impostato la radio come da manuale
Ma il gyro non lo devo assegnare in nessun canale? va di default come l'msr?
Un'altra cosa. Ma perche devo scendere la corsa del pitch a 75% (positivo negativo)? non potevano diminuire la massima incidenza del pitch, direttamente dalla curva del passo?

si sbagliato e il 681xx tipo RC-Bearings.com

provato fuori . motore tiene bene per cca 4,5..5 minuti in volo a stunt2 100% motore con 2 lipo hyperion da 160 e molto meglio. adesso ho da volare. ieri aspettavo in campo per una batteria che finiva veloce. adesso o tante piu potente...adesso si divertimento. vedro quanto tiene il motore...

gioco su manine e. ho dovuto limare il spindle da 0.4mm per avere le manine senza nessun gioco...

Secondo me il bulletin è fuorviante. Dopo aver smontato e rimontato con i frenafiletti (vite sicuramente a battuta) il gioco sulle manine era sempre presente, uguale a quello che rilevo ora (ho controllato e la vite a croce è ben serrata).
Secondo me l'unico modo per eliminare il gioco è limare lo spidle come ha fatto firedragon.

anche io ho un decimo di gioco, ma è una normale tolleranza dello spindle, non è motivo di rottura dei cuscinetti, la vite del resto è ben salda, difficilmente riuscirò a smontarla in futuro

4 decimi sono esagerati, qualcosa non va sicuramente

ora mi tocca tradurre tutto il post di fulvi

Dai firedragon, questa è la strada che porta a casa

Io preferisco la lipo unica. Vediamo quando mi arrivano le Hyperion, non vedo l'ora

Alex, non me ne volere, ma E-flite proprio non ci prende con le lipo
