BETAFPV Meteor75 Pro Brushless Whoop Frame – 2-Pack (Black & Blue) – Triangle Motor Mount, 45mm Prop Support, Larger Battery Slot

The BETAFPV Meteor75 Pro Brushless Whoop Frame is a lightweight, durable upgrade designed for larger 1S brushless whoop builds. It supports 45mm propellers and features a triangle bilateral stretch motor holder that simplifies motor installation and improves high-speed stability. The battery slot measures 16.7 mm x 6.3 mm, accommodating higher-capacity 1S batteries like the BT2.0 550 mAh. At just 7.73 g and made from PP material, this frame is built for pilots who want precise, agile flight with enhanced thrust—especially when carrying an HD digital VTX. This 2-pack includes one black and one blue frame.

What makes the Meteor75 Pro frame different from other whoop frames?

The key difference lies in the triangle bilateral stretch structure on the motor holder. This design adds a third screw hole (3-M1.4-φ6.6 mm) that makes motor alignment and fastening much easier than traditional two-hole mounts. It also increases rigidity during high-speed turns, giving you a more stable flight feel. The frame is built specifically for 45 mm props and cross-type flight controllers with a 26x26 mm mounting pattern—it is not recommended for regular whoop FCs with a different layout.

What size motors and props work with this frame?

This frame is optimized for 45 mm propellers. It pairs well with 1102 or 0802SE brushless motors that use a triangle mount pattern (3-M1.4-φ6.6 mm). The included 26x26 mm FC mounting hole is designed for cross-type flight controllers, such as the F4 1S 5A, providing a clean build path for a 1S whoop setup.

How large is the battery slot and what batteries fit?

The battery slot has been enlarged to 16.7 mm x 6.3 mm. This allows you to use larger 1S LiPo batteries with higher capacity, like the BT2.0 550 mAh. The extra space gives you more flexibility in battery choice without modifying the frame.

Common questions about the Meteor75 Pro frame

Can I use this frame with my existing Meteor65 or Meteor75 electronics?

Yes. The Meteor75 Pro frame is a drop-in upgrade for pilots who own a Meteor65, Meteor65 Pro, or Meteor75 brushless quad. The electronics (FC, motors, etc.) from those models are compatible, provided you use a cross-type FC with 26x26 mm mounting holes and 45 mm propellers.

What is the recommended flight controller for this frame?

BETAFPV recommends the F4 1S 5A flight controller. It matches the 26x26 mm cross mounting pattern and works well with the 1S power system.

Does the frame include hardware or just the plastic?

This package includes two frames—one black and one blue—without screws, motors, or electronics. You will need to supply your own motors, props, FC, and other components.

Is the frame durable enough for indoor and outdoor flying?

Made from PP (polypropylene), the frame is lightweight at 7.73 g yet tough enough to withstand typical crashes. The triangle motor holder adds extra rigidity around the arms, helping the frame hold up during high-speed maneuvering.
