Max Series - Max 10, Max 10 SCT, 3660 and 3652 combos.
What combo should you get?
Depends on the voltage you'll use and the size motor your vehicle fits. There is not a real world option that runs great on two different voltages.
The "Kv of the motor" determines the Voltage of the battery that is safe to use for a given setup.
An ESC's rating, only is for the ESC, not for the motor. The motor's KV, is important for choosing a 2s or 3s. A 2s motor will overheat on 3s. A 3s motor would run okay on 2s, slower.
If a motor's KV is too high for 3s, damage can occur rapidly to everything.
For 3s usage, "lower" than 4000KV is suggested.
For 2s usage, 4000KV and above is okay.
The motors are 2 sizes, normal size, 540, or larger size 550. The 3652 motors are 36mm diameter, x 52mm long, what is commonly a 540 size motor. The 35660 motor is 36mm diameter, x 60mm long, or what is a 550 size motor.
The shaft on the 3652 motors are normal 1/8 inch size. The shaft on the 3660 motor is a large 5mm size.
Regarding the gearing. Generally speaking, when a faster motor is installed, the "stock gearing" is wrong. Best to use a "Smaller pinion gear" (Gear on the motor) to be safe when doing system changes. Stock spur gears are usually fine. A smaller pinion gear is always a good idea. Smaller the better, but mid to low "teens" is typically a safe place to start.
The size of the wheels/tires, and their weight also directly effects gearing. Larger heavier wheels, are like a larger Pinion gear. So if there are larger tires installed, the pinion size should be reduced more to help deal with the added load from the larger wheels.
We have had reports of shut downs and over heating caused by basic connection problems. Weak plugs, or not enough "C" rating can lead to basic issues and problems. TRX, "deans", or "T style", or "EC" plugs have been a source of some problems. Problems from the size of the plug, to the wire "floating in solder" will make the ESC shut down. Wire "floating" in the solder also causes a weak connection that makes the ESC shut down, power down, reduce power, or blink a code.
We suggest the "amass" brand of XT series plugs. They make an XT90 that is good for most setups. The C rating on the pack matters as well. Even with 50 C packs, we can get our vehicles to do shut downs when we "drive aggressively" . Reacts very much like the connector problem. To help get around this, the ESC's punch setting can be lowered, or smaller pinion gear often helps.
