I just totally screwed myself. Messed up my back an my bike trying to test something. I'm not going to make it.

Needed a second person to swap swing arms, but didn't have one and screwed up my back trying to do it myself. If I wasn't hurt and had help I could put the bike back to the way it was, but I'm out of time because I have to work tomorrow. This sucks.

I wanted to let others test ride the bike or let someone else race it even though I didn't think I was going to race myself.

[Alan B]

Major bummer. Take care of that back.

[zombiess]

Major bummer. Take care of that back.

I just got the bike back together and almost rideable. I took several oxycodone pills and waited for them to kick in. I have to wait and see how bad I am tomorrow to determine if I can make the drive or not. I hurt like hell, but now all i need to do is re-install the 18 fet controller and some velcro ties. I also need to rent a SUV if I'm going to take the bike. Just have to wait it out and see now. I don't think there is any way I'd race. Someone else would have to. My main reason for going was to let some people test ride the motor so they could see what it was like.

I have a rider for you. He is very good.
He is my crewchief, so he will be there.

[bigmoose]

This is going to be a blast! 20 electrics entered from what I heard when talking with Luke and farfle last night. Zomb, be safe, but just take your pieces parts to the track; and I'll bet the guys put it together for you. Looking forward to the pix and vids tomorrow!

The bike of death, the 2Pi, the new cromotor and 17 others! Think of this years competition versus just two years ago. The advancements being made by you guys beats a fortune 500's pace of technology development.

I feel like shit. Yesterday it was coming out of both ends. Feel a little better now. I might be a bit older than most, but I haven't missed a race between the stinkers and the geeks yet.

So ... I hope I can get up and going tomorrow at 4:00 am. Sorry but I can't take the van/ gen/ parts/ popups/ tables this time.

I'm sure that I will have my usual unhelpful comments and pics though.

[acuteaero]

A little update from my point of view this evening- I left track at about 9:30... couldn't hang any longer, just exhausted. Staying in the Motel 6 in Victorville- or one of the two motel sixes, which are across the street from each other. Don't understand how that works.

PaulD's bike ate the Lyen controller I bought from Lyen yesterday and installed last night- I modified it to eliminate the cutting-out issue as seen here: viewtopic.php?f=2&t=16910 ... I installed additional shunt resistors for a total of four, then used the software to limit the current to what I thought was a safe value- turned out it was running more current than I thought and quit working. I need to troubleshoot it more fully tomorrow. There are some nice melted solder chunks rattling around inside, know that for sure. And one phase of blown fets, at least. Zombiess volunteered to apply his large body of knowledge about the Infineon controllers to help me scrape together something- if we're lucky we'll have a working bike again tomorrow. It was super fast while it was running today, though If we get it going again it probably won't be quite as fast again

I also rode around a little on my HS hubmotor "bmx" bike, it's pretty good except for the sorts of not quite right things that you always get when rushing to a deadline and not preparing as well as is really needed. I'm not really much of a racer so I may ride it around with the slow gas guys and just have some fun. I think that anyone trying to push it to limits would get very frustrated by all the "not-quite-rights" about it...

Running chargers off the Prius HV battery works perfect and is super slick. Actually tried it for the first time this afternoon at the track. Mean well HLG and RSP are kickass chargers. Kokam cells seem OK and pack builds seem to have mostly worked out, some small questions to confirm when I have some more time but mostly OK. Kokam cells are definitely not the performance level of good hobby lipo cells. They warm up under load/charge and sag more. But they balance nice and are very consistent.

SoSauty and 999zip showed up today, those were the only other ebikers I saw before I headed out. I have heard directly and indirectly that LFP and crew, Farfle and Stevil Knevil and friends are all rolling in later tonight.

Should be fun tomorrow! Looking forward to it!

Im about an hour out.

Sorry to hear about the lyen controller blowing Acuteaero. Exploding controllers is the curse of the big HXT motor. I think PaulD only ran 65amps battery current on an 18s pack. Thats enough to be many hundreds of amps of phase current with that motor, and phase amps are all the controllers FETs feel.

2pi in surgery. I give the patient a 99.9% chance of timely recovery.

[Doctorbass]

Good luck everybody!

I would love to have my Giant racing you all!.. but i would need to drive like 48h non stop! and would arrive at the race so tired that i would not be able to flip the contactor switch!

Won by a massive margin in the fast bikes heat. The video should be good.

Roached the pack from my own mistake. Swapped to spare pack. Somehow the controller threw a fault for mosfet shorted. Confirmed no mosfets are shorted. The fault is factory reset only. We may be boned. We are talking with sevcon support.
