pins

Does anyone have a good source for a quick release pin with a grip length of
3/8 to 1/2 inch range? I'd like to use 2 pieces of one inch angle and a
quick release pin to make an interior fastener for my battery door.

Spruce offers ones that are too long and the Wick's catalog offers one that
is too short. 

Thanks in advance for any suggestions.

Mark

Hiroo, I read a report by an owner with an IVO who
used "PTC" fuses. These are the electronic fuses that
"Blow" and remain open as long as the (overload/short)
persists, but reset when turned off or the problem
goes away. This owner said that the "PTC" would blow
practically the instant that a limit was reached on
the prop.

I use the PTC electronic fuse with my IVO and this solves the blown breaker 
problem.

Larry, 
 
Sounds like a good idea. 
 
1, Where do you get one (& pt #?)
 
2, Does it fit in the normal spot of the breaker, or do you use it in  
addition to the origonal breaker? 
 
Thanks. 
 
 Kurt
