Background: we are a community-based, volunteer-operated FIRST Robotics Competition team run by a small nonprofit organization. (We teach high school students STEM & teamwork skills through competitive robotics.) This drone was used professionally by a local company. When they upgraded to a newer model they donated this one to us, but no batteries were included. They told us it was still flying right up until they upgraded.

We believe this is flyable with the addition of batteries, but we don't have the budget to buy a set to prove it. Ideal for someone already familiar with the model, wanting a backup spare or full set of spare parts.

Open to reasonable offers. Local buyers preferred (we are located an hour northwest of Boston) but we are willing to arrange shipping at buyer's cost if desired.
