24mm Engine Spacer (pack 2)

Use these spacers to fly D engines in engine mounts design for E engines. These heavy duty tube spacers are a loose fit in standard BT50 tube so there is no chance of them getting stuck inside the tube (which can often be the case when making your own spacers from expelled engine cases).

These spacers give you the flexibility to build all your 24mm powered rockets with engine mounts 3-3/4" long, yet still fly them on D engines whenever required.

Spacers are resuable. Every range box should have a couple of these!
