I suppose it depends on which bits went missing! (That's my last byte at the gigacomment!) [badass]

if you are calm and collected when all about you are going berserk - you've missed something important!

This video might give some clarification of the difference between digital & analog, if anyone is interested in the technical side.

Any views on the benefit of a higher frequency pulse to the motor?
I would have thought that at some pulse frequency the reluctance? of the motor coil would start to resist the pulses and actually reduce the magnetic forces in the motor.
In electronic terms each motor coil is a substantial coil wound over a iron core.

Not sure whether it has any relevance, but a lot of servos do have coreless motors ?

I have never actually taken one of these 3.7 g motor apart so I don't know but I doubt they are. I have one that is US so when I have minute. ;)

Since 'coreless' is a relatively new offering for servos I'd be surprised if market penetration had reached down to us, given the extra cost.
A coreless servo is very easy to turn when disconnected and will be much lighter for a given torque than its cored counterpart.
Note that it will still have 2 brushes. A cored motor has an armature (that's the bit in the middle) where the windings are wound onto a central (heavy) metal core. The armature is supported at both ends by bearings and spins inside the external magnets.
A coreless motor has the magnets on the inside and the armature is wound as a cup shape that spins on the outside. Because the windings are self supporting the armature is much lighter and is capable of accelerating much faster. Keeping in mind that it has only one bearing at the commutator end I would say is unlikely to survive any kind of impact.

Although drifting off a bit, coreless motors tried to make an entry into the model rail arena.
As Simon put, because of the lower mass, the motor starts and stops a lot faster - but they seem to have less torque. Although irrelevant here, they also have a bad reaction to high voltage track cleaners that the older 'can' motors just shrug off.
-
So - their best use is for very fine stepper motors, where positioning accuracy is more important than loading.

if you are calm and collected when all about you are going berserk - you've missed something important!

I have been waiting for a Lemon stab receiver for the HE162.
Ordered on 17th December from Lemon direct in Hong Kong. Posted 18 Dec but China Post track and trace shows it only got as far a Ho Chin Min City, Vietnam, 2 hours later, then nothing ever since.
Complained to Lemon and a very nice customer services lady emailed that Lemon will send another today. with track and trace and also included a basic Lemon 6 channel rx for my trouble. Can't grumble at that - unless of course they both only get as far as Vietnam again!

Blimey! I admire your patience, couldn't you have sourced a rx in Britain?

balsa is best.

Eric is quite right, no rush.
It is not so much my patience as the 'skin flint' in me objecting to paying at least 20% more for exactly the same thing.

Who buys from the dealer, who buys from the Far East! (and all adding their own 'mark-up' to the price.)

Slowly moving on with connecting up the electrics.
An usual picture looking through the hole in the nose where the battery box will be fitted.

Showing the 3 plugs for the elevator, aileron and ESC as well as the battery wires from the ESC.
The Rx and UBEC yet to be fitted, or even delivered, but will be placed under the battery box requiring a temporary access to be cut on the fuselage underside.
The engine nacelle is now glued in place and the motor wires soldered directly onto the ESC. This time sods law was in my favour and the fan rotated the right way first time!
