Z3007 (only) Backmount Set

The 6mm shaft on the prop adapter is long enough to allow fitting most backplate-type spinners. We strongly recommend that you use Hyperion ( #HP-LPRING-EP-S6 ) Precision 6mm Smooth adapter rings with APC "E" propellers, to insure a precise fit and less vibration. For HP-Z3013, 3019, 3025 series motors, use part#HP-Z30-BKMNT, which includes 5mm collar for the heavier shaft in these motors.
