how coincidental, ive just been looking for one and found it like yesterday
http://www.mcgirt.net/index_RC.html
the actual main MH-53E page is here:
http://www.mcgirt.net/RC/MH-53J/mh53j_index.html
it also sais "Who Makes the Kit? Lars Zander in Germany, see his link below. This is custom built fuse - alot of work to be done"
if it doesnt come with the fuse... i dont know what kind of a kit it is, but nevertheless its the best thing i could find.
good luck -Matt
