Ittybitty's BJV4 XR10

No puffed up packs...I've probably cycled all of my 4 packs around 10 times or so and continue to get 35 -40 minutes of steady crawling out of them too. That's a guess at the time, but its at least that much. I've never thrown one away so I don't have a total number of cycles or any idea what to expect, but they keep going strong. I'll probably trash them due to rock rash before they give me any other reason to get rid of them!

That's the biggest benefit of running a pack that costs $8.22...if you beat the hell out of it it's not that big of deal to trash it for safety concerns as if I had spent $35 or more on it. I also don't even worry about hitting them...just another part of my rig that allows me to focus more on driving and not on whether or not I'm gonna break something.
 
I heard that! Thats why I want some of them for screwing around with

For most packs I have a lexan scrap corner from some truck body that is insulated with a thin receiver box pad. Then it just sits over my pack and stays put from velcro strap. Works pretty darn good and you can rock back and forth all you want to flip back over, with no problems. Protects the pack at contacts very well to greatly reduce chance of shorting. I just need to find a couple more cheap, .040" bodies that have that corner molded into them

You have to look close but you can see it in these two pics:

It is, they think your wasting money. Then you tell them how much they are and they want some, so they dont have to worry about their lipo on their rigs.
 
I took some time at lunch to install my new RC4WD gears in the rear axle of my crawler. The gears look great and the mes looks really good as well. I did run into one issue though. If you install them in a transmission using the VP motor plate you will need a small washer or shim to go between the idler gear and bearing on the main shaft or the gear will contact the button head screw on the VP plate that holds the upper link mount in place. With the shim in place the gears line up just fine and nothing is bound up or out of place. There is enough room for the shaft to move towards the bearing case on the outside of the transmission without hitting the case. I test fit it before I closed it up for good and the case buttoned up without any gap.

I'm not sure why VP used the button head screw in this location but it would be nice to have it countersunk instead. I suppose the other option is grinding on the head of the screw enough to clearance it for the gear, but the shim was easier and didn't cause any problems.

How thick of a shim are you using? My gears should be here any day now.

I just remembered to check this for you...

.47mm

or

.018

I guess its more of a washer than a shim...but either way you know what size it is.

The new upper link mount comes with a pan head screw for attaching to the vanquish motor plate. I haven't installed mine yet but, I think that the motor plate is counter sunk already to accept the pan head screw. Can you confirm since you just had it apart?

I can't confirm if they are countersunk, but I don't believe so or I probably would've put one in from the beginning. I just can't remember right now...I'll probably install the fronts today and if so I'll get back to you on this.
 
Well VP_Monkey cleared this up but here's a pic for proof...

it can't be countersunk because it sits higher than the bearing...it actually holds one of them in. You would have to countersink it lower than the bearing to be able to use a pan head screw.
 
How do the RC4wd gears sound? Do they have a noticable gear mesh sound like the axials? I just installed them in wifes rig but no radio yet to test them out. Noticed that clearance issue too. I think the gears should have the spacer machined in as a lip

Good Luck at ECC Itty!

Hope you bring home one of these:
