0:32 I thought this too at first but the KV rating of a motor doesn’t mean kilovolt. The KV is actually the rpm needed to produce 1 volt of back emf, so a 3800 KV motor will need 3800 rpm to produce 1 volt or back emf. It also dictates how fast the motor can go, since an ideal motors max speed is reached when the back emf equals the input voltage and the motor will use no power, but due to non ideal conditions due to friction and other factors the back emf doesn’t reach the input voltage so it always uses at least a small amount of current. When you add a load to a motor it slows down the motor and that in turn leads to a drop in the back emf, which means the voltage across the motor increases and hence it uses more current. In a stall condition the motor isn’t spinning so isn’t producing any back emf and hence the motor winding has the full voltage across it, this causes a very high current, in DC motors you are essentially taking the inductor which is the motor windings and just turning it into a resistor since with no changing currents the inductor has no resistance.

@@jinanprojects that is commonly a sign of not using a high enough temperature or having too much cooling, it happens because the current layer doesn’t melt into the layer below it properly, you should try less cooling and a higher temperature. Ideally for filaments like nylon you want an enclosure too, to help reduce cooling more and to keep the part hotter, so less likely to warp and better layer adhesion.

Straight cut are better for torque capability and simplicity of manufacture for sure, plus have the benefit of no axial forces I agree. They're relatively limited in ratio range but if you have huge differences in gear size it's going to be a fun trade-off between strength/efficiency of a single pair, or using an intermediate set and accepting the efficiency hit to get a meshable set with less rotating mass etc. Drop them into a small bath casing and put a super light lube in there that just picks up the tips of the teeth and mists the lube without adding much drag.

Some tips from my experience : You could use herringbone gears to get rid of the axial forces(tricky to print but might work), a softer front suspension maybe with some oil to reduce bounciness, and also some sort of rear suspension just like in pan cars. A gyro would help to keep it stable. Check out where the car needs to be balanced and also try to get it lower to the ground. A high gear ratio will give you a higher top speed, in theory but a 2:1 ratio will not provide enough torque for high speed , i think you can achive a lot higher speeds with this setup , what limits you is the lack of stability. Id be happy to help you if i can Overall great presentation and very clever designs .Definately subscribing, looking forward for more !

At zero load the motor spins at 100% rpm potential. At 50% load it spins at 50% percent rpm. It is a inverse linear relationship. For motors like this you do not want them loaded more than 30% at top speed (for multiple minutes of high speed driving). Should be easy to figure out, measure the zero load RPM and you can do the math on MPH to RPM to see what the load is. Also, are you going to add suspension on the rear axle? I’d recommend looking at the old school classic RC10L chassis, which had a solid rear axle and was able to do some suspension on it.

The reason the axle was printed lying down on the bed and with a flat spot is so the extruded lines go right down the length of the part. The individual extruded lines are stronger than the layer adhesion, when you oriented it vertically the only thing holding it together was the layer adhesion. A better option if possible would be to print the axle in two halves, both lying flat on the bed and combining to make a cylindrical shaft. Or you could just flatten the other side of the shaft to balance it.

I'm surprised you didn't use double helical gears for the motor. They get rid of the axial force issue that helical gears introduce and are still easy to 3D print. If the gear generator doesn't happen to have an option for those, just mirror one half-as-thick helical gear back to back. And as the other guy suggested: create an enclosure for them while at that, so you can put grease on them and have it not be thrown into orbit after 5 seconds. Just grease without an enclosure will do basically nothing, as it will just be flung out the second you throttle up. Unless you're using graphite powder, that might be sufficient in a thin layer that could stick around, literally. Backseat engineering aside: a very impressive project you got there 👍

Double helical gears are a great option for 3d printed gears. Reorienting the fan could allow you to use the cooling system as a down force generator. Active down force like that will be super useful for sustainable high speeds because of the scaling problems of aero. If it always crashes the model could end up being overbuilt. I really hope this helps. No matter what I'm loving this project man. Good luck.
