Thank you Hal for the kind Words my friend
those that have these hobby engine Abrams will know the availability of an Idler is non existent so i set about creating my own version

as those Kenny kong tracks are darned heavy it needed to be metal here's what i did:

built the adjustable idler for it now



used an old Metal Tiger arm cut to size and some "BRASS" gearbox standoffs 3 in total for the wheel axle arm axle and the axle for the tensioning arm



Beefed up the inside wall with Brass plate to add strength
