HAPPYMODEL Mobula7 V3 Frame 75mm – Upgraded Black Whoop Frame for FPV Racing Drones

This 75mm wheelbase frame from HAPPYMODEL is the V3 upgrade for the Mobula7 whoop series, designed to improve durability and add an LED strip mount. Weighing just 5.5 grams in smoke black, it fits the Mobula7 HD and works with Happymodel 0603, 0703, 0802, and EX1102 brushless motors, plus 2S or 3S 300mAh batteries from Happymodel or GNB.

What's new in the V3 frame?

The V3 redesign focuses on toughness. It's more rigid than the V2 frame, helping the drone handle crashes better. A dedicated mount hole for an LED strip board is included, along with slots for the Super Tiny LED Strip Board. If you've broken a V2 frame, this is a direct upgrade.
