What arming switch are you using?

[Paul Taylor]

I’m using mostly Cobra ESC’s. What arming switch are y’all using.
I could make up a plug but thinking a switch would be less parts and weight.
A picture and a source would be helpful. Thanks.

You want an external arming plug solution. 
When it's unplugged the system is externally identifiable and verifiable as inoperable. 
Switches can be bumped or left on.
An external arming plug is definite.

Paul,
I have use a single throw toggle switch from Home Depot. I have used these for over 10 years, it is a positive shut off and works great with helpers that are not familiar with E power. Yes, you do have to be carefull once you plug in but this goes for external plugs also. For contests I usually plug the pack in once I get to the circle then arm the system once I give the hand signal to begin the flight. At the end of the flight I have the helper shut off the switch and hold the airplane until I can get to it to unplug the pack.

Best,   DennisT

I concur with Brent Williams

Murphy’s law is alive and well.  If it can go wrong, it will.

I have had success with a Hobby King Unit with a Deans plug.

Here is a photo of some installations of the positive shutoff switch I use.

Plug 100%  I make mine from XT-60 connectors.  Male end is flared into the fuselage.  Female is the plug.  Simple wire crossover and cover with shrink wrap.  I always have 3 in my flight box.  Never lost more than 2 so far!

My arming connection is made from IC3 connectors. No more Dean's for me.

Hi Paul,

How do you mount the IC3 connector to the side of fuselage?

I am with you on the "no more Deans".  What makes the IC3 better than the XT-60?

Hi Paul,

How do you mount the IC3 connector to the side of fuselage?

Dennis

I make a 1/16" ply plate with the exact cutout for the IC3 connector, and JB weld it to the connector. The plate has 2 2-56 nuts also glued on. I then have a hole in the side of the fuse matching the IC3 connector, and 2 holes lined with a small carbon fiber tubes for the 2-56 bolts to clamp down on the ply plate mount.  That way the outside of the fuse can be finished and per normal, and only the button head 2-56's show along with the plug.

Smaller and lighter. The male side has 4 slots and applies pressure to the female side. If one of the 4 tangs fails,  the connection still works fine.
