They seem very small though and after going back and reading the description and the reviews I am afraid they are only for a smaller racing drone. Could anyone confirm whether these will actually be ok or if I need to order some different ones? I also have a the pixhawk flight controller and the F450 frame. Thanks in advance!
While they may work in theory, they definetely complicate the setup because the motor mounts on the ESCs are not compatible with the bullet connectors of the motors you bought. You will have to buy bullet connector adaptors for these.
If you use these, you can skip an entire part of the assembly involving soldering female bullet connectors to your ESC or ESC wires. I’ve used these for my quad and they haven’t failed me! The only downside is that you have a smaller distance between your Flight Controller - ESCs - Motors, so if your quad is longer than the 450 or you don’t organize the wires well, it could be a very tight fit.
I bought all my drone parts from amazon and have returned quite a few after finding better deals, you should try to return these or keep them for a future project.
