3-1/4″ Spacewalker 4-BLADE Aluminum Spinner
$52.95 – $68.95
4-Blade! Shaped for the "SIG Spacewalker", this spinner is a hit with sport- scale and competition modelers.
The 3-1/4 " was our first Big Bird spinner and has become much more popular with the amazing growth of Giant Scale in the hobby.
We have 3 other shapes in the 3-1/4" the P-51, F.A.I. and AT-6. Also available with light backplate.
Available in 2-3-4 blade. Click to see additional image!
Prop Range: Up to an APC 15.5x12 Four Blade.
Engine Range: This Spinner is generally meant for the bigger engines like Big Zenoahs or Quadras or up to 3.2 Sachs conversions. You can easily take this spinner off the shelf and run it on anything from a 4-stroke 1.20 to a 3.2 Gas motor. This spinner can also be slotted by us for just about any Prop / Engine Combo that will fit into the cone.
