Manual

Keys

d/D
increase/decrease hydraulic torque converter pressure (htc; boost controller)
e/E
trim aileron left/right (let me know if there are more suitable keys for these)
f/F
increase/decrease water-methanol injection (wmi; more boost when boost > +0mmHg)
m/M
increase/decrease mixture
N/n
fine/coarse propeller pitch

Note

Shinden is an aircraft that has a canard configuration with a pusher propeller, which means it is relatively easy to stall. Thanks to Dave Perry's suggestion, Shinden has become much more stable compared to the previous version. But you might still sometimes crash this aircraft. Thus, careful and gentle control, especiall for elevators, is a "must" in flying Shinden. When you feel a sign of stall in rolling, yawing, and pitching, push the stick back a bit to recover. The use of autopilot is not recommended since some of its functions (Such as vertical speed) may rapidly control elevators.

As Shinden has a six-blade propeller that flies aircraft at 405kt, it tends to roll into clockwise direction. Be prepared to adjust this roll. You may use e/Shift-e to trim the aileron for this.

Putting down flaps makes Shinden nose-down. Adjust elevators before / after manipulating flaps.

As of Feb. 06, 2007, Shinden has the flap-driven elevator-trim controller so the nose doesn't go down as it used to be. But it still goes down a bit so be careful.

Note for those who kindly commit this into the CVS repository

First, please unzip and apply the diff file above at the j7w directory with -p1 option. Second, extract the binary files at the j7w directory. Finally, commit the files with the comment that includes all the revision info from the last check-in in the Revision History section below. Thanks for taking time for this. I really appreciate it.

Note for users

This aircraft is made for FlightGear CVS but is compatible with 0.9.10. Only the differences between these two versions above are the key configuration for propeller coarser/finer and nasal scripts at this moment. Clickable features in the virtual cockpit works only in FlightGear CVS.

To do

  • More gauges, more authenticity
  • More accuracy in aerodynamic coefficients (I need more info on these)
  • More accuracy in engine and prop.
  • 3D model is rough, can be improved
  • Autopilot configuration (needed?)

Earlier versions

Revision history

Please DO NOT post a crash log here. it's hard to read and is not worth reading for most of users. Email it to me directly with some additional information including exact FlightFear version, machine spec, and what was you doing when it went crash. Thank you.
