"Dad, I need help with my science project." I groaned when heard this. I knew he had to do one because he elected to skip the personal research project earlier in the year and now needs to do a science project. Due in a week. Ack.
K. So whaddya wanna do?
"Something with RC cars."
We decided to take a methodical approach to selecting the correct size pinion gear. The correct size being defined as the pinion gear that delivers the fastest top speed and maintains a stable motor temperature below 180f. It's cold out so we may lower that threshold a bit.
We designed an experiment and the Mojave is the guinea pig. Advanced speed detection technology is in hand (we found a sick lidar gun). We know a great spot where the road is smooth and straight and the traffic light.
Locktite has been applied to all the grub screws in our 11t-20t range of pinions. Wheel bearing have been replaced, and the body reinforced and a windshield added.
Tomorrow we see how fast this thing will go, hopefully without burning it up.
The car is a beat up, but relatively ship shape Mojave exb with proline badlands lp 3.8 tires and a castle 6s esc with a broken off fan and a 1515 2200kv motor.
Huh. Can't seem to add pics. Maybe I'll figure it out tomorrow.
