Tru-Turn Double Jam Nut Adapter Kit for YS DZ Series Engines

Specs:

8mm x 1.0mm

Adapter kits are needed because there is no standardization among engine manufacturers, and every manufacturer makes the engine drive any way they want.  Tru-Turn adapters enable you to fit your spinner to your R/C engine.

Choose the True-Turn Adapter you need:

1. By consulting the chart below, you can find the right adapter for your YS, OS, or other pattern engine. 

2. The chart lists

    a. crankshaft diameter and thread size,

    b. a brief description and approximate weight,

    c. part number, and price. 

2. When you see more than one listing for a crankshaft size and thread, select the adapter for a long or short crankshaft.
