Even with the worn out birdcage bullets. To each his own on that topic
A loose bird cage or bullet plugs will not arc as bad and get as hot with a lower turn, lower power 2wd motor/esc and lower load from less weight compared to a 4x4 with a high amp draw esc/motor combo (especially the new high power 4 pole motors). Add a power hungry servo that you would not use in a 2wd to that as well and you have a lot more power going through the bird cage or bullet connector in the 4wd.
I change my bullet connectors often as they wear like the bird cage, the prongs squish together over time and need to be replaced. $2.50 insurance.
You can probably let your 2wd go longer, but the 4wd will arc bad enough to melt lipo cases or worse if you let them go too long before replacement.
