Bell has been passionate about his quadcopter project for some time now.

This accomplishment was not without its challenges.

After multiple fires, prototypes, and adjustments, Bell’s Peregreen 2 dashed through four speed runs.

for achieve this feat, the Bells designed a drone with four motors on a carbon fiber frame.

The motors on their previous drone were Velox V2808s, but they went for even larger ones this time.

Using T-Motor Velox V3115s caused an immediate setback.

Their initial prototypes kept bursting into flames, a disheartening event to any drone maker.

Their motors were overheating their batteries, necessitating a redesign.

The Bells considered quitting, but stayed the course.

Eventually, they made a prototype, with thicker wires for the motors that could successfully fly.

Though the Peregreen 2 could successfully fly, it was not initially at record-breaking speeds.

At full throttle, the drone went from 0 to 186mph (300 kmh) in 2 seconds.
