Hey brtaman

I bought a sackload of them from Jason Rollette of railgun fame, years ago. I gave some to Richie Burnett in a futile attempt to pesuade him to build a brick-powered coil, and sold some others on.

I did have a Stinky, but the frame cracked and I'm riding a Cove Hustler now. Booked up for some freeride fun in Whistler this summer :D

Cracked the frame? Damn, you must've been giving it some major punishment. suprised The frames are built like tanks, with some extreme welding! Where did it crack? Mine has been rock solid lately and i've been punishing it in the alps quite badly (we are pretty lucky as far as tracks and mountains due to Slovenias location shades).

Whistler is amazing from what i've read and seen, have fun on that!


Getting back to the IGBT's I have tried searching for any DN11 series datasheet to no avail, I am at the point where I don't even care anymore to be honest mistrust, it will work at 50khz which should be ok anyway, just need to get some lexan for protection. shades

The swingarm... Link2

It was just starting a tiny crack, but I never really liked it anyway. I bought it used, and the previous owner might well have punished it too.

I've heard Slovenia has some pretty big mountains Link2

Yes, just fire the IGBT up and see what happens :P

Ouch man. Think you just bottomed out the rear suspension too many times? Mine makes a nasty clank when I just off something relatively high and botch the landing, going to check my frame out as well.

Yeah the mountains here aren't bad, not exactly Himalaya high, but it does have the alpine feel to it. Most of the time I ride Karavanke range anyway something like this Link2, the northern Alps where Triglav is situated is either WAY too steep or protected. -.- We do have a couple downhill runs in that area.

How is the scene in your area? Also good freeride/downhill?

More on-topic: While waiting for wire to arrive, I have fired up some OLD SKM50GB100D bricks, the impressive part is that they hum along at 160khz without latching and/or exploding. :)
