Now available from Future World Models is the Answer RC Muti-tool. A must have tool in anyones pit box.
It gives you 8mm Glow Plug Nut Driver, 10mm Clutch Nut drive and rather than just being a handle we have included a 3mm and 5mm Hex for engine mounts or PBS systems. Though not needed by everyone Answer RC figured it may as well have them as not have them.
The tool itself is machined from steel meaning that even the tightest of glow plugs or clutch nuts need not split the tool.
The handle can be removed and stored in the shaft of the main tool body.
