Hey Guys I need to get some quick moneyknow for another knee reconstruction, so I'm selling my boards in parts or full, the only problem is I don't have the trucks any more, I still have the mounts but I sold the trucks.
So for $400 NEG you get a preassembled deck only missing trucks,
You get:
Abec 11 wheels worth $60
Twin ESC 120A worth $200
2 motors worth $50 each
Battery worth $50
BMS and charger worth $50
Alien full kit with custom rey mounts worth $400
Deck worth $100
Alien cases $30
RC controller $20
Total savings $600
If you don't want to use the rey mounts you can buy just the caliber mounts and a set of trucks or I can send you a set of holey trucks and mount included in the price
Thanks guys

So, I bought Jacob Bloy's old Alien setup because I really wanted to see how the other half (with the more sophisticated/pricier setups) lived. Now I've had the board running for a few days for a few days I have to say I'm shocked so I'm here to get some help/answers. My issues are:
Braking: What little of it is present on this ESC seems to come with 3 braking levels - off, barely anything, a little more than barely anything with lots of jittering. The brakes cannot decelerate the board on even the mildest grades here. I've been riding with a HK150A before this and braking is creamy smooth all the way from off to able to wind of considerable speed on the steepest of slopes. Is there some way to get this kind of braking on the Alien dual (psuedo) 8S ESC?
I do see why you can get away with such long belts now as the braking is not hard enough to cause them to slip.
Acceleration: Similarly I am used to very smooth linear acceleration but again the ESC seems to "step" rather than gradually increase. I thought this might be a problem with Jacob's crappy (sorry Jacob) remote but I bound a new TX and I'm seeing the lack of linearity in power supplied.
So is there a way to program/upgrade these issues away?

All those symptoms seem to be that the ESC was flashed wrong. I'd try reflashing it and testing it again. The brake is normal and does work. You have to get the right flash on the ESC. I'd probably ask Bruno or Beets what the current one to flash too for your model.
Though in the interim - the motors have a lot of "slop" in them. The drive shaft has well over 1mm of axial free play and is actually only stopped by the fact the pulley makes contact so I am yet to see how far it actually moves. Is this normal? usually if I get this much play I'd think I'd killed a bearing but there there is no sideways play so I don't think this is the case. I'll get the pulleys off when I get home but working away at the moment so don't have a full set of tools so can't check just how much play there is.
They are the Alien motors with the red bell ends - does anyone else find this?

I assume there's a retaining ring on the shaft present ? (like picture in this thread : http://endless-sphere.com/forums/viewtopic.php?f=35&t=56568&start=50#p859477)
How much slop do you have ? It depends on the motor if you have more or less slop, I do have the black alien 6374-170 motor from Bruno and it almost has no slop (but it's a little more expensive than the 'red one')
You have to know that when the motor is running, the rotor will be kept on its (axial) place by the magnetic field, so I think it's not a problem.

Tap on the same end as the grub screw or the opposite end to the grub screw? Sorry if it would be apparent but wont see the parts again for 24hours and just want to clarify before the weekend although it doesn't look like the programmer is going to show so maybe the Alien gear wont get a run with the other boards this weekend

a grubscrew usually is fastened with locktite. If this screw will not get loose, heat it carefully with the tip of a soldering iron, the locktite will come loose.
Is there anyone in Southeast Queensland with an Alien ESC that can lend me a programming cable. Been waiting two weeks on one that I was promised and starting to feel it might not be coming. As it is the board is pretty useless as it runs so rough and brakes so poorly that I'm the only one who can ride it and the way terrain is around here that just isn't fun... and the idea of buying was to be able to get out on the boards with friends.
Alternately, is there anywhere I can get a similar programming cable ... I know, ask Bruno ... but just wondering if there's a local alternative I might be able to pick up without waiting for one to fly across the world.

Hi.
If you send me your address I'll post one for you. Alternatively you can easily buy in Australia. Local shop or online. It is a standard usb to ttl adapter. 2way communication. +5v gnd tx rx. Make sure to put the pin in the right sequence or you will damage the Esc logic board.
Regards

After talking to Bruno I found I had the required hardware already (though took me a week to find my USB TTL cable). Thanks to everyone who offered help. I am still waiting to test the new settings as we are kind of inundated with a rain from a cyclone at the moment.
I was wondering though, what kind of brake settings others were using. Bruno only recommended 50% brake but from testing on the covered part of the driveway this seems a little lame. I live in a very hilly area and one of the key reasons for electric boards for me is the ability to brake... but with current settings it seems the brakes will be nowhere near enough to provide any noticeable deceleration on local hills. Is there a reason not to dial the braking up a lot higher (heat for example)?? Is there a thread discussing and comparing Alien Power ESC settings and performance somewhere?

Possibly, a firmware issue? The brakes are decent and I'm running them at 70% but have set them at 30% and they were still fine then. At faster speeds the better it stops to a certain extend - 15 mph requires a specific amount of space for stopping distance. It's best going about 5-10mph and stopping versus going 1mph and stopping.

I understand what you mean and do get how they should work/feel with respect to EMF backpressure during braking being directly proportional to speed/rpm as this is my 4th electric skateboard - though as I built the other 3 myself I am just trying to come to grips with how much brake is acceptable before the Alien ESC goes pop. Bruno seems to feel 50% is the safe zone before frying it and since it's regularly 30C+ here and roads are often 50C+ maybe even that might get them too warm especially if they stay inside one of the Alien plastic covers.
I am a little disappointed (scared of getting cleaned up by a car actually) with the braking at 50% - at 30km/hr it really does not shed enough speed fast enough and on some of the steeper slopes in my cruise it struggles to shed speed at all. The motors also feel very rough when braking at full brake ... I can only descibe the feeling as riding over cobblestones. I find it something I can adapt too as an experienced rider but it is far from smooth. My HK150A/SK3 brakes feel no different to mechanical brakes - very smooth ... except of course the braking pressure declines with speed as expected and mentioned earlier. I e?xpected the alien to be similar... anyone compared the two ... suggestions of what the issue might be?
