Default BD First Run Impressions

I was able to get my BD built and tuned just in time to race this past Saturday. I love the way this car works. It was very fast right out of the box, although, I had to re-learn how to run with a one way diff.

At the end of the day, I was able to do 1 lap more than I had done the previoius week with my CGM, although I didn't finish as well (my fault).

I think that I'll be saying goodbye to my CGM.

Default One Problem though...

Has anyone else had problems with batteries falling out after a hit? I had 3 packs become unseated and partially break apart.

One of my packs actually came out of the car and was dragging on the track. I don't think that has ever happened to me. I felt like a total novice.

I used the foam on the bottom of the battery hold down plate, but it just doesn't seem to be sufficient.

Am I the only one???

I had the same problem; so when I need the batteries to stay in I tape them.

Default Batteries falling out

Had a full race with my BD with some smaller and bigger hits, only once my batteries slipped out. Maybe it would be better to use tape or a alloy or reinforced batterystrap?

Randy,

You mentioned a few pages back that you used JB weld to create a fixed centre pulley. I thought this was an American only product as i had not heard of it, but have found a source in the UK.
How is your pulley holding up? Could you please let me know how you went about this...piccies would be good as well

Steve (Speedtech) have you been able to find out if the locked pullies are coming in the next order from Yokomo?

Cheers all
Chris

Chrissy ,
Randy was talking about the front one-way being "JB" welded together to make a spool, not the center pulley shaft. Steve said locked shaft may come in the next yokomo order. (crossing fingers)

randy DID JBWeld his center one-way, he is also going to be using a spool soon.
my understanding is that the yokomo locked center drive is about 2 more weeks off.

"I locked up my center pulley by drenching the 1 way bearing in JB weld and packing it inside the other bearings as well, then installing it on the shaft while it was still wet."

Went back through and found it, Rob you were making think i was losing it then!! Also gave a run down on how he did it so i am good to go!

Sorry I had remembered him saying something about jb welding his front oneway a couple pages back. must have missed it.

At least when you are in error, someone willl usually provide you with the correct information. Sorry about that.

I used JB Quik, it cures relatively fast, and dries in about 4 hours. I had to do it twice to the pulley because the first time didn't have enough time to dry, but since the 2'nd time I dont have any problems as of yet. I also used it on the front 1 way, and I'll give that it's first test as of tomorrow.
