The biggest problem with constant reworking of a solder connection (like repeated motor swaps between chassis) can cause component damage. You can degrade the motor or ESC from repeated high heat exposure.
So be careful when soldering not to let heat spread far.
Or try to route wires in a way that allows you to remove the motor and ESC without needing to disconnect the wires.
Thank you for info
I bought some 3.5mm orca motor bullets for that exact reason but i think motor bullets give more resistance maybe?
I use hakko 888d 70w (with 5mm tip) and i can remove the connection pretty fast so i dont think there is much heat that goes to the motor...I also always let things cool off before i desolder the next wire. The esc is safe as i hold the wires with my fingers when i remove the wires from the motor..not hot enough to burn my fingers..
Great solder iron!
