Motor spray 101
Any brand of motor spray should be fine. Same goes for oil. Just make sure you buy "Bushing" oil, not bearing oil.
Droop settings. The TC3 instructions might have some recommended "Droop" settings. Stick with those to start.
If not, I would run a little more than 1mm in front and 2mm in back. The car will be easier to drive for you being a Novice.
