[NSRCA-discussion] Arming plug manufacturer and source?

[Chad Northeast]

In general 4mm bullets can deal with 80A, 5.5mm 150A, 6mm 200+A, Deans are 55A rated, 3.5mm are 50A rated usually.

F3A typically is around 30-35A average during a flight with peaks of 70-80A, so 4mm is  sufficient, Deans are good, 3.5 is a little small, and anything bigger than that is just bonus :)

For Deans its important how you solder them as you can really hurt the rating if you overheat the housing which causes the pins to not make good contact.  Same thing with bullets, you can overheat them and take the spring out of the leaf's which will cause poor contact = higher resistance.  Its important to try and keep the housing on a Deans and the leafs on a bullet cool while soldering.
