Just a quick note for those of you who might be interested about my recent attempts at Larry Coslick's Cat IV EZB record of 35:01.

Over Labor Day weekend at Lakehurst, I came close to Larry's record with a flight of 34:30 on Labor Day Monday. The model reached a maximum height of about 165'. The air was not so good earlier in the day, but when the model was launched at about 5:15 pm, I believe the air was very good.

This past Sunday at Tustin, I made some good flights. First was a 33:02 that cruised at 140'. Second was a 32:02 that cruised at 150'. The 32:02 looked very good until the last 100' of descent was faster than expected. For the Tustin flights, I used a propeller that has a modest amount of flare in order to slow the climb.

As the saying goes, "Close, but no cigar." I'll continue the "quest" next year.

Some information on the model and motor:

model weight: 390 mg
prop: 13" x 29", 105 mg, symmetric, 5.9 sq in per blade
motor:
 - 11.4" x 430 mg (34:30)
 - 11.4" x 450 mg (33:02)
 - 11.8" x 475 mg (32:02)
 - 7/99 Tan II

This model is the one I flew at USIC. It has a relatively stout 6.25" motor stick.

Thanks to all the timers: Alan Mkitarian, Steve Brown, John Alling.

For each of these flights, I had to make steers at high altitudes. I have to thank John Kagan for giving me the crucial tip that I needed. Immediately, I became significantly better at steering.
