Sorry for the repeat but I got no reply posting this in it's own thread.
I've got an s-brick in my Horizon Express train and am using the publical available Horizon Express profile to run it. I've got 2 lego train motors that are hooked up to ports "C" and "D" with "D" inverted. The ports are assigned to the "Drive" slider and which works very well. The control panel also has two additional buttons on it which are "coast" and "stop". I would like each motor to be able to do all three funtions but I havent been able to figure out how. Right now the only sure way to stop is to exit out of the control panel as it is dificult to get the drive slider exactly centered so that it is truely off. Is this possible?
Thanks, Scott

Version 1.5 of the Horizon Express profile was messed up by Profile Designer (the infamous 'rename interface element' bug), but there is a new version 1.6 that should work, I think.

Hi. It's safe to use 9V with the SBrick. I've used LEGO old 9V batteries cases (both 1xPP3 type and 6xAA type), just need to use a PF cable as an adapter because old 9V plug is not compatible with SBrick PF-type plug.
If you're going to control just a M-motor, a PP3 battery works but doesn't last long, 6xAA is better.
Is there any chance that running an SBrick with a 9v battery might cause it to short out or cause thermal shut down? I've been poking around the forum a bit to see if I can find an answer. I'm less worried about the voltage because it seems like a 9v battery is well within the operating peramaters of the SBrick. I guess my question is; is it likely that using a 9v battery to power the Sbrick and a Power Functions M-motor would cause enough resistance to bring the peak amps up to around or above 3amps to cause damage to the SBrick or motor ICs?
Hi Nick,
It's a know bug in the iOS apllication, but our developers already fixed it. ;) The new fixed application will be available in the Appstore soon.
You can use your own background in the Profile Designer. Just choose a background, edit it with paint or photoshop as you want and uplodat it ;)

How many XL motors would it be possible to connect to a single sbrick?
hHve 4 XL morotr that I would like to control at the same time. Would I need one or two sbricks for that?

You can use one SBrick for that, but the current limit of the LEGO power source may degrade the power of the motors. Alternatively you can use custom LiPo or you can hack the battery box..
You can use both, Matt. There are Pros & Cons:
- Disposable batteries (1,5V each) deliver 9V but are heavier than LiPo batteries
- Rechargeable batteries in a standard BB are usually 1,2V types. They are as heavy as disposable batteries but, by definition, can be charged again and again.
- Rechargeable LiPo battery boxes deliver 7,4V and are lighter. They are rather expensive, so it's a personal choice regarding your budget !
In terms of power for an RC Car: the current draw of a given motor doesn't really change: for example, the 5292 RC Buggy motor draws around 1,4A, no matter what the voltage is.
The power is equal to the voltage multiplied by the amperage, so if you choose 7,4V instead of 9,0V, the electric power - hence the mechanic power - is of course lower by 18%. You will save something like 30g, but that's nothing in the global weight of a Lego Technic RC Car. And the power/weight ratio is critical for a car...
How this will help :)

Hi,
I am new here and I hope this is the correct topic...
I hve bought 2 sbrick (which has not yet arrived) and I wanted to "test" the iOS App in advance with my iPhone 6.
The problem is I cannot login to the social network? I have tried to use the same login l am using for this site and I think this is correct.
Any advises for me?
Yes you can, thanks for these converter cables:
