Gravedigger Nose

This mod is mean! I took Michael Baddeley's original Gravedigger front-end and made it even more aggressive with two servos instead of one. The original model had issues with actually flipping over other tracked racers. This version will flip a much heavier Mecanum racer like Ares over!

Additional hardware to covert a stock Piranha front-end to a Gravedigger front-end are:

90° 25kg servo X2

M3x4x5mm heat-set insert X2

M3x30mm countersunk bolts X2

M3x16mm countersunk bolts X4

M3x10mm countersunk bolts X6

M3x3mm socket head bolts X8

I plugged both servos directly into the receiver. One servo goes to the channel on the receiver that corresponds with the stick on transmitter you want to use the weapon with. The other servo is plugged into an open spot on the receiver (I chose Chanel 5) and is mixed in the transmitter to work at the same time as the first servo. On the transmitter (controller) hold down OKAY and navigate to the SETUP menu. Scroll down to MIXES and turn MIX 1 ON. Set the MASTER for the Channel servo 1 is on. Set the SLAVE for the Channel servo 2 is on. Adjust the positive and negative mixes so the two servos move opposite each other (because of the way they're mounted). When the servos are installed, before attaching the Servo Arms, check that the output shafts are positioned and function like they should to avoid damage to the front-end.

This mod is still being torture tested for longevity.
