I never planned to change from 24 Volt.
Oops, my misinterpretation of what I read. That said, I support what BPF has said, it's a "needy" engine to maintain. When they ran well, I really enjoyed flying them, but I had times when one was not running correctly. Although the fix for those cases seemed fairly simple, the diagnostics weren't always so.
The engine was removed due to time-500 hrs. Nothing wrong with it, just by certification this is/was the rule
Is that 500 "removal" requirement a DA-42 rule? I have not heard of that one....
