new used Magnum
 

today I flew the Magnum... what a hoot!

the previous owner thought it a bit much with a OS .46LA and pipe.

Itis the 1st generation Magnum with the wing/saddle GAP
but the price was right and I had this Dubb Jett sport .50 crying out for an airframe.

I had to add two ouncess of tail weight. Hitek HS-525mg servos on the elevator and ailerons. The trim in flight was a blast, but not ballistic, the fresh engine was run a tad rich till break in is done. Prop was 9x8APC wich will be changed soon.

On the SJ-50

Cut back on the prop.... and use the 9x7 for a half dozen flights or so (maybe more like 10 flights) if it is still relatively new. Launch it about 600-800 rpm down from peak. Let it scream....don't worry... ya won't break it.

Then go back to that 9x8 :) Let me know what it tachs at that point.
