Am building a WM World Star 40 and the steering arm and the wheel collars have a metric set screw that I can't find an Allen wrench to fit. Have a Hobbico metric Allen wrenchset but the 1.5 is too small and the 2.0 is too large. Can't find a hobby shop or tool store in Las Vegas that has anything in between. Built a WM T-34 that seems to have the same hardware, but they must have included the correct Allen wrench with the kit since I don't remember having any problem. Have searched my workshop from top to bottom but I can't find an odd wrench anywhere. Does anyone know what I need and where to get one? Airborne doesn't answer their phone or return my calls as promised by their answering machine.

A 1/16" allen wrench is 1.5875 mm. Maybe they sneaked in SAE parts?

that's probably it. i'm sure they snuck in a non-metric item since it's crazy that a metric allen key doesn't fit it. And no... there are no standard metric allen keys between 1.5 and 2mm. At least not that I've seen. I always thought they included one in their set. try to locate it in the kit. good luck!

I found the missing allen wrench from the T-34 kit stuck in the box for the Magnum .46 that I am using on the T-34. Don't have any idea how or why it ended up there, but all's well that ends well. Still don't know the size. Thanks.

that's good news :-) good luck. the t-34 is a great plane, too. easy to fly and looks great.
