Pro Series II™ 29 mm Motor Retainer Set

I use these in my scratch builds. It is a great feature to add to your designs. For me, this is a must have.

The more expensive aluminum retainers are not needed for mid-power 29 mm motors. Rough up with sandpaper the inside surface of the retainer and the exterior surface of the motor tube before applying epoxy to mount the retainer.

Simple, effective, and affordable retainer for your 29mm engines.
