Time for my very own, very first build thread!!
2nd hand libre race 102 mountainboard - Paid 85€
I saved money on this, because I'm no experienced rider and I felt like my money could be spent better. However, it's the key to my whole build, because my focus is on being able to remove all of the other parts and put them on another board without any changes. (Will depend on the shape of the trucks I have to admit).
Motors / ESC
I ordered and received 2 2kW 270kv motors and the twin ESC (8s) which Bruno sells as a "package". Couldn't test them yet (waiting on other parts).
Check out the package at http://www.aliendrivesystems.com
in the motor / ESC section
The package came with banana plugs on the motors and banana plugs to be installed on the ESC wires. Also some accessories were included (mainly for installing a prop for planes, but also some useful ones!). Also a USB-stick with very intuitive easy-to-use software was included with which you can set up your ESC before riding.
I definitely forgot to order some parts (don't you always...) and I hope that I can find them in shops around here.
First of all: WTF 116$ SHIPPING COSTS???? Then again, I guess that can be explained since it's coming from Honkong and weighing about 7kg. One thing that gives me some peace of mind: 580$ is around 441€, which feels like I've just gotten a massive discount ^^ What psychology can do to you...
It'll take some time to get here, since 1 item was in 'back-order', which means they have to order it, before you can order it.
Anyways, here's the list of the part names in my order:
ZIPPY Compact 5800mAh 8S 25C Lipo Pack
Hobby King GT-2 2.4Ghz 2Ch Tx & Rx

First I had a technician at work make me some truck clamps. They worked very well, but they're far too large and heavy:
I've designed some new mounting pieces which are now in production. They will be made by a supplier of ours at work. The parts will be made in Inox steel and will be lasercutted out of sheet metal. Since the hobbyking order, I told them that there was no rush in lead time, so they promised me the parts in 2 weeks.
I promise you better pictures when I have the pieces! =)
Mounting plate is 5mm and clamps are 8mm in thickness.
Any questions/remarks? Shoot!
I'll keep this thread updated when there's news to share
I've got a first question: How the hell can I parallel balance charge 3 8S zippy compact lipo's, when each pack has just 1 pair of power supply leads, but 2 balance leads (4s each)??? I could get a 6-parallel 4s balance board, but then how to connect the voltage supply leads? They have 8s in between them...
Another thing I could do, is make the 2 4s leads into 1 8s lead (I'll have 1 spare wire afterwards). But 8s 3-parallel balance boards are hard to find...
