Wasabi, extreme aerobatic slope glider.
(http://www.flybiwo.com/ and http://www.baudismodel.com/)
To fully enjoy flying with Wasabi please select "load
mixer default" to automatically setup the preset mixers
(flap & spoiler compensation and snap-flap settings).
For more info see suggestions in model/wasabi.xml and
in documentation/models/Readmefirst_Wasabi.txt.

<!--
Control derivatives for CRRCSIM are computed as:
CRCSIM_der = AVL_der * control_travel_deg / 0.5
Assumed control travel are:
de=+/-8deg
dr=+/-20deg
da=+/-15deg
flaps=+/-30deg.
Note that actual flap range should be limited to +/-8deg as camber
changing flap (e.g. as snap flap), while 30deg down deflection is
to be used for landing.
Best flown with snap-flap, using following mixer settings:
elevator: rate=0.6 (i.e. +/-4.8deg)
flap: -travel=0.133, +travel=0.133
mixer1: elevator-to-flap mixing rate=0.533
(flap +/-8deg with ele +/-4deg)
mixer2: flap-to-elevator mixing rate=-0.467
(elevator compensation 1deg down for 8deg flap down, to trim a DCL=0.8)
mixer3: spoiler-to-flap mixing rate=-0.5
(flap down 30deg with full spoiler)
mixer4: spoiler-to-elevator mixing rate=0.234
(elevator 6deg down for 30deg flap down)
AVL control derivatives in standard orientation stability axis
(for 1deg of control deflection):
CL_de= 0.0134
Cm_de=-0.0375
CY_dr=-0.00384
CY_da= 0.00115
Cl_dr=-0.000128
Cl_da=-0.0105
Cn_dr= 0.00146
Cn_da=-0.000414
CL_flaps=-0.0553
Cm_flaps=-0.0084
Note: CY_b and Cn_b are likely respectively under and overestimate
due to the missing large (in side view) fuselage, in AVL model.
Therefore the original values
CY_b=-0.226
Cn_b= 0.0887
have been corrected (just guessing) by factors 2.0 and 1/1.5 respectively.
CD_prof, Uexp_Cd, CD_CLsq and CD_flaps data from TP42 & TP29-9% polars fit,
plus estimated fuse & tail drag (from surface area).
Reference Re=200000.
