Radial Engine Expertise You Can’t Find Everywhere

Bear Technologies LLC founder and lead instructor David Eldridge brings rare hands-on experience with live radial powerplants to the classroom. During his tenure at MIAT College of Technology, David was one of only two instructors entrusted with the regular exercise and airworthiness maintenance of the school’s live radial aircraft. On a disciplined monthly schedule he kept that engine viable, monitoring its health and ensuring it remained a functioning instructional asset rather than a static display.

That kind of stewardship requires more than technical knowledge. It requires genuine familiarity with how radial engines behave, what they need, and how to read them. At Bear Technologies, that experience translates directly into instruction. Our students don’t just learn about radial ignition systems, timing, and powerplant management from textbooks. They learn from an instructor who has actually done it.

That is the Bear Standard.
