RE: Magnum XLS 52 - A 'Hunk of Junk'?
My Magnum 52 required quite a number of runs before the motor would run well. It tends to blow a lot of OS #8 plugs too. I went through 2 plugs with only 1 dozen flights. Mine had bearings that went bad so I shipped the whole thing to Global Hobby for replacement. No response so far after 10 days. I replaced it with OS 46FX and Jettstream tuned muffler, expecting to get 16k rpms with new set up in my F20. This is more pricey but much more power than the Magnum could ever muster, and less headache with tuning problems and bearings issue which is priceless...[:-]
