DUBRO PROP BALANCER TO BALANCE MONSTER TRUCK WHEELS AND TIRES
I used the original base as a template to make the holes in a 150 mm X 80 mm plate of aluminum. The two pairs of holes are spread apart 120 mm.
This is the rod that goes through the wheel. It comes with two coned shaped pieces. I added an old Maximizer 17 mm hex, a tube of plastic as a spacer and a collar with a set screw.
And this is a sequence of pics on how I assemble a wheel on the shaft in case you haven't figured it out by the pics above already.
LIPO BOX
I read that a .50 caliber AMO can from the army surplus is just right to store lipos. It’s water proof and would contain any fire that could start inside. I will probably get one in the future but until then, I have been using this little metal tool box. In case of fire inside, flames could escape from four tiny holes at the bottom corners but it’s way better than a cardboard box. I always keep it on the garage cement floor.
Testing this slipper clutch is boring, just running back and forth doing hard starts to make the slipper slip gets old very fast. So I decided to bore you with a video of part of a boring testing session. I don't like to be bored alone. At first, the slipper is too tight, even the CD doesn't prevent the truck from wheelying. After adjusting the slipper twice, I get it to slip a lot to test it's durability. Near the end of the video, you can hear it starts slipping quite a bit. But I didn't tighten it after I stopped filming, I just finished the packs doing my race simulation and surprisingly, despite the fact that the slipper was slipping a lot at the end of the hard starts part, the truck ran very well and the slipping was less noticeable during the rest of the packs. It's probably because it got to be very hot during the abuse of the repeated hard starts and got to cool down during running normally. One thing I found weird is about three quarters into the video, you can hear that slipper slipping and all of a sudden, I pop a wheely and then, it starts slipping again. Things that make you go ''hmmmm'' I was running my new 2S packs I made earlier by the way.
I am trying out this clamp type servo horn. I like the fact that it clamps on the servo’s splines but I thought it was too short for the kind of steering I like on my ERBE so I made a small piece out of aluminum to extend the horn’s throw.
