The dozer is back up and running and so far so good. I put the esc in exponential mode and and added expo to the radio as well. The dozer is a lot less responsive set up this way but it is better than blowing motors. I also put more slack in the tracks as they may have been a little to tight. If the track were this loose in a real one you would cause some serious damage but what works in the 1:1 doesn't always work in scale.
The hood is made up of two pieces an L shaped piece that makes up the fire wall and a plate for the U shaped hood sides and top to mount too. The hood top has a hole pattern in it to mimic venting panels so when the two pieces are put together the holes get blocked off. So I took apart the hood and milled out the lower part of the top panel so the holes are now open. This does two things for me it allows the dozer to have air flow through the grill and out the hood. It also allowed me to mount my speaker for the Servonaut SMT under the hood and project the sound out of the holes. The sound system is a lot louder now and sounds so much better.
In this pic you can see the holes in the top of the hood and instead of drilling all of those holes in the lower piece I just separated them and milled out where the holes were. Nate suggested this and it was a darn good suggestion, thanks Nate.
