[NSRCA-discussion] connector search

[Dean Pappas]

Hi Gang,
You really do want to use a Sermos or Anderson Stackpole connector for this.
All the connectors you have mentioned rely on the first-contact surface as part of the final mate, or rub that first contact area against the entire mating surface.
The Stackpole connector mates and the arc damaged area rolls away from the mating surface. This is better for low loss over many cycles and flights.
There is even an outfit that now sells a mated pair of the 45 Amp stackpole connectors glued into a Du-Bro fuselage wall-mount switch.
For our purposes, you'd need 2 of the size we often see in aeromodelling, or one of the next size up.
later,
Dean

Can't help with those specific connectors - however I do exactly the same thing with the Deans, mounting the female in the fuse recessed so that the male (when connected) is flush with the fuse surface. I make a handle / jumper from brass stock / heat shrink. 
 
Works reliably and, as you point out, provides for convenient and safe connect / disconnect of the power.

All, we are using these connectors to make up our Jumper Plugs for higher amp, and Pattern electrics. The female goes in the plane on the Plus lead from the battery to the ESC and is mounted with a bracket to take the "push in--pull out loads.The Male pins are jumpered with #12 wire and then insulated with heat shrink,  as a result the resistance through the jumper is not measurable on my Fluke
We call it "Sparky" because it snaps when you plug it in--ESC load-.This way you turn on the Rx. and check the plane out--then plug the jumper in--listen to the arming/check sounds- move the throttle to idle--and go fly. When you land you pull the plug--then turn the Rx. off--that way you do not rely on the ESC or throttle "off" to make sure the motor does not turn back on.
Have seen a couple actually do that after landing and stopping, once before someone got to the plane, and the second as it was being carried back.  
The plastic body measures 0.355in long X 0.280in thick X 0.500in wide.
Contact area is about 0.160in deep and 0.350 wide-gold plated-, on each side, so it can easily handle the I.
Now the problem--I bought these in a hobby shop several years ago, and of course he no longer has them, or even remembers them. They have more contact area than other similar   connectors (Anderson power poles),so are the best thing out there I have found. 
Does anyone know where I can get some, or who may have made them. I assume they were originally made for cars.
There is a second e-mail with the oyher two views coming.
Thanks
Jerry
