Some of you have already figured that out, but seriously I ran the front drive Sproket off my Tiger(Heng Long) as I was pushing snow, and lost the screw that fastens the wheel to the drive axle. What machine size are the threads, so I can go buy another one????

try emailing matotoys at their web site. they'll likely know.

They're M3X10. Standard hardware. Regards JZ

Did you have the "hubcap" in place? That'd stop the screw going anywhere...

Blew the hubcap off and then the rest just started happening. It was dark and the snow deep. Didn't see anything wrong until it was too late.

You can find it in the spring time!

Try a metal detector, found plenty of missing screws and clips that way

Use M3x15 Allen capheads instead.

1.They're a damn sight easier to get into the sprocket on the end of an Allen key.

2.Put a spring washer and a penny washer on them(hence the extra 5mm length)and they don't come undone anymore.[>:][>:]

Thanks. I found one that worked laying around my workshop(Phillips). I will buy some allen head ones .

Use some Blue Loctite too!
