My Magnum 52 decided it was broken in while I was at Edgewater last week, so I fired it up and did some tuning and testing. It's allowed its full rev range now, and that transition...nnf.
If this clone runs this nice I can only imagine how well a genuine OS FS52 would run!
Other things tested: Flight duration at cruise throttle(I ran it for about 32 minutes before aborting the test; it only had three cranks of my hand pump's worth in the tank, safe bet to double my 10 minute flight timer heh)
Volume(62dB at idle, 74dB at full blast, measured a foot away with a smartphone app)
Transition(See linked video)
Need more thumpers!
