Cobra Brushless Motors offer performance and value for Sport Flyers and
Competition pilots alike. They are built from high quality components,
and are designed to give years of top-level performance. All Cobra
Motors are shipped in a custom designed package that features protective
foam on all six sides of the box, with 3 separate compartments to
protect the motor, accessory pack and cross mount.
The Cobra 3525 series motors have a 5.0mm shaft for extra strength, as
well as oversize ball bearings to support the shaft and provide a long
life. The internal bearing measures 11mm x 5mm x 5mm and the outer
bearing measures a massive 16mm x 5mm x 5mm! The stators are made with
0.20mm lamination for maximum efficiency and minimum Eddy Current
losses. Also included on the motor are ultra-flexible motor leads with
high-temp silicone rubber insulation and 3.5mm bullet connectors already
installed.
To complete the package, a complete hardware accessory kit is included
with every Cobra Motor. Included in this hardware kit are the following
items:
-
Heavy Duty 3mm Thick Cross Style Motor Mount
- Four M3x6mm Motor Mount Screws
- Bolt-On style threaded prop adapter with 3 screws
