Roll Rate

File: In sw/airborne/fw_h_ctl.c we define the roll rate loop:

float cmd = throttle_dep_pgain * ( err + h_ctl_roll_rate_igain * roll_rate_sum_err / H_CTL_ROLL_RATE_SUM_NB_SAMPLES + h_ctl_roll_rate_dgain * d_err);

Note that the roll Pgain is variable with throttle and multiplies through the entire equation affecting the I and D terms as well for ease of tuning.

The Pioneer Village complex comprises 28 buildings on 20 acres housing over 50,000 irreplaceable items of historical value, restored to operating order, arranged in groups and also in the chronological order of their development.

There are 12 historic buildings around the circular "green". There's a Frontier Fort, a real honest-to-goodness Pony Express Station, an Iron Horse, and a home made of sod. There's a general store and a toy store, chock full of all the goods from yesteryear. An original art collection including 25 Currier and Ives prints, 23 Jackson paintings, and the largest single collection of Rogers statues.

You can ride a priceless steam carousel, see 17 historic flying machines and marvel at 100 antique tractors. See the world's oldest Buick, a 1902 Cadillac and a 1903 Ford, both designed by Henry Ford, plus 350 other antique cars, all displayed in their order of development.

"chronicles the development of the world’s first commercial manned space program--a program that includes an airborne launcher (the White Knight), a space ship (SpaceShipOne), rocket propulsion, avionics, simulator, and full ground support. With ample illustrations, photographs, and behind-the-scenes information, SpaceShipOne provides a full picture of this classified project--from the conception and design to the deals that brought together Scaled Composites’ Burt Rutan and Virgin Airlines’ Sir Richard Branson to the plans for building a fleet of commercial suborbital spaceships and launch aircraft. The story of SpaceShipOne combines the adventurous spirit of Charles Lindbergh, the entrepreneurial drive of Howard Hughes, and the urgency of the space race at the height of the Cold War. Author Dan Linehan, who was there at the launch, lets readers in on the drama and details behind the making of spaceships that will take twenty-first-century tourists to the final frontier. "
