I think its a bit mistake to have the switch inside the fuse... I mount mine outside.. along with a great little ($15.00) led display that has 5 indicator lights that tell me the status of the rx battery.. so there are no mistaken how much charge is left.. the $15.00 is good insurance,, rather than losing the plane.
Also.. always mount the slide switch with on in the "rearward" position.... That way.. if you sideswipe something.. it won't push the switch to "off".. and also a "loose" switch won't migrate to the off position by sheer inertia. Push to front for "off".. push to back for "ON". (and don't ask about vertical switches..>..)
Just my 2 cents... joe
