3 Shoe Clutch Kit 

To suit 1/8 scale models made by Hi Speed, will fit a few other models using a .21+ engine (not all). To help ensure a fit please check measurements below:

14T Clutch Housing - 20.4mm wide - outer diameter 28.1mm

2 x Ball Bearings included 10mm x 5mm x 4mm (ODxIDxW)

Lightweight alloy flywheel: Outer diameter 34.40mm - Center hole dia 8.6mm

Axle - to fit 6mm crankshaft thread - 11.1mm long (entire length)

What to check to ensure a fit?

Check the crankshaft thread measures 6mm and that the crankshaft length will manage the axle + flywheel, so a length of 14.57mm minimum to 20.57mm maximum along the threaded section. After the threaded section their must be a smooth section following for the 10x5x4 bearings to fit, this must be 5mm in diameter. No screws or washers are included with this set. The type of crank required is a SG crank. Short cranks such as featured on some .21 SH engines will not be suitable.

What engines will fit these fit?

.21 + engines from the following makes have been checked to fit already:

SH .28 (SG crank must be used) / VX / Ansmann / Team Infinity

In general if it has a SG crank 9/10 it will fit, however please check the above measurements first to avoid any fitting issues.
