 To prevent the battery from banging around int the car, to keep it on one place, and to balance weight a bit, the battery needs to be strapped down securely. To do this, I got a [[http://www.amainhobbies.com/product_info.php/products_id/138739|Tekno RC V3 Universal]] battery tray that I have mounted slightly raised from the chassis bottom so that it clears the side guard. On the tray, I have mounted lengths of velcro straps to secure the battery in all directions. To prevent the battery from banging around int the car, to keep it on one place, and to balance weight a bit, the battery needs to be strapped down securely.

 The RC Monster motor mount has (in my eyes) a flaw that makes it impossible to use the break-assembly  on the side of the differential where the motor-mount replaces the original differential mount. Also, the position of the engine can does not allow the space for the brake discs on that side. For this reason, I only have braking on the side of the differential there the original differential post is used. This means I only have mechanical brakes on the front wheels. The RC Monster motor mount has (in my eyes) a flaw that makes it impossible to use the break-assembly  on the side of the differential where the motor-mount replaces the original differential mount.

 My current mechanical setup of the servo for the brakes is really not optimal. The servo is mounted on a plate extending from the steering-servo mount, and ends up being slightly higher than a standard buggy body shell is in that spot, resulting in me having to cut an opening in the body shell at that point. I'm not at all happy with this. I suspect that the force required to get adequate braking is low enough to allow me to use a mini- or even micro servo. This will be experimented on, and I hope to get a better mounting arrangement for the brakes in time. My current mechanical setup of the servo for the brakes is really not optimal.

 What DID end up as an "immediate replacement" however, was the 3200KV motor. On the absolute last run, the magnets/anchor came completely loose off the motor shaft/axle, making the mag's rotate in the motor without transferring any power to the shaft and drivetrain. Bummer. I have bolted on the 3000KV, and am hoping that it will hold together better than the 3200 one did. What DID end up as an "immediate replacement" however, was the 3200KV motor.

 +Not a lot of driving, as I was track supervisor this day. That, and because of water. I managed to run the rig into a fairly deep pool of water, causing mud and water to enter the ESC, killing it off. Testing the ESC at the track indicated that it was completely dead, and I feared I had destroyed the most expensive part on the rig in under a week's time. 
 +
 +Back home, i pulled the ESC completely apart, and thoroughly cleaned out all signs of dirt, dust and corrosion using electronics cleaner, pressurized air, a copper brush, cotton sticks and patience. During this process I really built up respect for the craftsmanship and engineering done by Tekin. This ESC is solidly built! 
 +
 +The work of cleaning it paid off, and the ESC still lives.

 +I notice well that I am still getting to know this rig. This day, the servo coupling decided to be all places but where I wanted it to be. The fit-ring of the servo horn and the attachment at the servo both decided to wear down hard, and no matter how much tightening I did to the attachment screw, the servo horn slid out of place.
 +
 +Back home, I replaced the fit-ring and the screw, and got a proper solid fix. I also discovered that the servo-saver was completely solid, with no give at all! That explains the all-too-soon wear of teeth on the servo out-drive. So, the saver has been trimmed and adjusted, and now has medium slipping, witch should be just right.

 +Replacements time. I smacked into a heap of pallets, completely busting the differential housing and a turnbuckle of the front left upper arm. I also spopped off one of those blasted C-clips in the process.
 +
 +On the bright side, the adjustments to the servo-saver seems to have been spot on, with not too much give, but actually a smoother, more responsive feel. Seems like that overworked HS-325HB gets a better chance of actually moving the fronts when there is a little give.
