Thanks, Mike.  This helps a lot.  I'll try some more rubber and "more turns!" as an old flying pal used to tell me.

Cheers,
Dan

Thanks guys.  Dan, the thing that seems to be making the difference in my models is more rubber.  My good flights have been with motors weighing 20-25% of total flying weight.  The motor loops are 3-5x hook-peg distance, and the cross-section ranges from 2 loops 1/8" on 20" span models to 2 loops 3/16" on the 24-26" span models.  These motors can be wound to between 1500-2000 turns, which gives motor runs approaching 1 minute.  I still have a lot of learning to do, especially in getting the models to consistently glide well after the power runs out.

Hope this helps,

Mike

Wow, Mike! That was sensational. I need to pick your brain about how to get additional duration on my guys.  They fly well enough, but just not too long.

Lovely! And congrats on the max.

Took the Wicko to the Spring Opener contest in Gainesville TX this weekend.  Weather forecast was iffy, and sure enough Saturday morning was a complete washout.  After lunch the rain stopped and winds died down for a couple of hours, enough to do a bit of trim flying.  Sunday started a bit dreary but turned into a very nice day for flying.

With the large field area I was comfortable trying a bigger motor in the Wicko - put 15g of 3/16" rubber (2x31" loops, 25% of flying weight) in the model, wound it to 5.5 oz-in (~1400 turns) and got a 2:56 flight.  This is my first max (over 2 minute) flight in FAC competition.  Had several other very nice flights on lower winds.

Also got some good flights out of the Waco SRE, Little Gem and T-28.  The field was beautiful - lots of grass and wildflowers.
