DJI Mini 4 Pro-Flying Catholic Priest Is Building a 131-Church Drone Archive for the St. Cloud Diocese

Flying indoors with a drone requires a different kind of discipline. No GPS lock, no obstacle avoidance to lean on, confined spaces where prop wash bounces off stone walls and wooden pews. Father Mitchell Bechtold, a 40-year-old Catholic priest serving parishes in central Minnesota, logged roughly 100 hours of outdoor flight time before he ever spun up a prop inside a church. He says those hours came from a genuine love of photography, not calculated preparation. Either way, the results speak for themselves.

• The project: Father Bechtold is systematically documenting all 131 churches across the Catholic Diocese of St. Cloud using drone footage, building a visual archive for future historians, planners, and parishioners.
• The gear: He flies a DJI Mini 4 Pro for most of the work, calling it his pick if he could own only one drone, and recently switched from his phone to an iPad as a controller display.
• The progress: 45 of 131 churches documented so far, roughly 35% complete, with a goal to finish by the end of this summer.
• The source: St. Cloud LIVE reported on the project in depth, including quotes from diocese communications staff.

A Pandemic Idea That Became a Multi-Year Mission

Father Bechtold’s preservation project is a direct response to the COVID-19 pandemic. When churches across the country closed for social distancing in 2020, he saw a gap: parishioners had no way to connect with their physical spaces. His answer was to digitize those spaces. That idea has since grown into a structured, diocese-wide documentation effort covering 16 counties in Central Minnesota.

“There were so many people who weren’t able to interact with their churches in a physical way, so I thought, ‘Why not digitize it?'” he said.

The practical trigger was simpler. A former parishioner from Spring Hill came in to shoot exterior drone footage for the parish website. Bechtold handled the interior himself, and the combination clicked. He earned his drone pilot’s license, built his hours, and started flying church to church.

DJI Mini 4 Pro Powers the Archive

The DJI Mini 4 Pro is Bechtold’s primary camera drone for the project. He describes his needs precisely: pro-sumer capability without the complexity or cost of professional-grade hardware. The Mini 4 Pro sits in exactly that range, offering 4K/60fps video, omnidirectional obstacle sensing, and a sub-250g weight that makes transport to remote rural parishes genuinely manageable. He owns roughly three drones total, but the Mini 4 Pro is the one he recommends without hesitation.

We’ve covered the DJI Mini 4 Pro extensively in our six-month review, and the praise Bechtold gives it tracks with what we found in our own testing: it’s a forgiving drone for tight spaces, with solid image stabilization that holds up even when prop wash creates turbulence. Flying inside a stone church with 40-foot ceilings and no GPS is not a casual exercise, though. The manual mode discipline he built over 100 hours of outdoor flying is doing real work here, whatever his original motivation for logging those hours.

He’s also made one notable workflow change recently: swapping his phone for an iPad as the display. Composing interior shots on a small phone screen, especially when trying to identify a specific crucifix or altar detail at altitude, is a real limitation. The larger iPad display changes the framing process entirely.

What He Actually Shoots and Why

Every church visit follows the same structure. Bechtold first identifies the elements that will resonate most with people who grew up in that parish: a specific crucifix, an organ, a statue of Mary, the Stations of the Cross. Then he captures the standard framing: a center aisle flythrough, the full nave from above, and the exterior from multiple angles. The goal is footage that works both emotionally and practically.

“If somebody is thinking back to their memories of their home parish, what’s going to stand out?” he said. “That crucifix always spoke to me. There was something about the image of Christ and the way he was portrayed. Oh, I loved seeing that organ or that statue of Mary, so I try to look for that.”

Barbara Simon-Johnson, associate director of marketing communications for the diocese, put the institutional value plainly: “It provides a visual record of our parishes from a perspective we haven’t had before, helping us document and preserve the history, layout and surroundings of each parish.”

The footage has planned uses beyond archiving. The diocese is looking at promotional materials, parish planning, and historical documentation. When a church closes, something Bechtold explicitly acknowledged as a real possibility for small rural parishes, this footage becomes the most complete visual record that community will ever have.

Aerial Photography’s Expanding Role in Documentation Work

Bechtold’s project is a concrete example of something we’ve written about before: drone footage accumulating commercial value that pilots often overlook in the moment. The combination of interior and exterior drone documentation, shot consistently across 131 buildings with a standard methodology, will be uniquely useful to architectural historians decades from now.

It’s also a clear use case for why the drone pilot skill set translates to far more industries than most people expect. Bechtold isn’t charging for this work, but the same skills, the same gear, and the same methodical approach could support a professional preservation practice. Real estate surveys, historic building documentation, municipal mapping: his drone pilot’s license opens those doors.

For pilots considering what drone sits at the pro-sumer sweet spot he describes, our Skyrover X1 vs. DJI Mini 4 Pro comparison and the three-way Mini 5 Pro, Mini 4 Pro, and Skyrover X1 breakdown are worth reading before buying.

DroneXL’s Take

What Bechtold is doing matters beyond the church walls, and I don’t think the drone community has fully absorbed why. The moment he finishes shooting all 131 churches, the diocese will have a complete visual record of every parish building as it existed in the mid-2020s: interiors, exteriors, architectural details, at a resolution and from angles that ground photography simply can’t match. That’s an irreplaceable document.

The fact that he did it with a consumer-grade DJI Mini 4 Pro and an iPad is the point. You don’t need a cinema-grade setup or a professional crew to produce archival-quality documentation. You need 100 hours of practice, a methodical approach, and the patience to do the same shot 131 times correctly.

I’d expect we’ll see more institutional clients, historical societies, preservation nonprofits, municipal governments, commissioning exactly this kind of systematic documentation work from licensed drone pilots over the next two years. By late 2027, drone-based building surveys will likely be a standard line item in heritage preservation budgets, not a novelty. Bechtold got there first.
