A "Lockhart Prop" Update...

[Bob Pastorello]

This past weekend, I enjoyed the challenge (ahem) of attempting to fly in the most incredible turbulence, gusts, and changes in direction of wind during a pattern contest that I can recall.  The first thing I made note of on practice day was that the APC 17 x 12 Std was WAY too fast on the Arresti (11 lbs), so I had to try the Lockhart Twister....bolted on at the motel on Friday night...
    Saturday - early enough to rudely awaken all the sloths in the motor home (Team A/S, you there??), I managed a quick test flight.  I was happily surprised to clearly see what I was after.  Good acceleration - not nearly as rapid on the bite as a 2 blade Std, but plenty good - and really exceptional braking.  The three blader just offerred this very smooth dynamic brake that really made it easier to manage things.
    My thanks to Dave Lockhart for doing his re-pitch, and my plea to Fred Burgdorf to make a mold.  The 15.5 x 12 three blade is a wonderful setup...mine was turning about 8150 on Magnum 15%, slightly less on two other brands I was able to run side by side.  I was very surprised to actually see 120 rpm difference on a prop of this load.
    Anywho - if you guys are looking for a great braking prop that still operates in the torque band of our motors - contact Dave Lockhart....(Lance - I'm sure he can replace your modified prop...<G>)
