Re: [Flightgear-devel] C310 Update
Hi Stuart, Thanks! How do you feel is the front-wheel steering (low speed, low rpm)? If I look from outside the wheel points to one direction but the action of the aircraft is very slow. At a little bit higher speed the a/c is sliding forward dispite the wheel direction. Just a hint, nothing more. I also wish you and your family a peaceful and happy christmas time.

As part of my changes, I removed the rear-most passengers to move the CG forwards a bit, as I found the C310 very tail heavy. Thinking about it a bit more, I think most of the JSB Sim aircraft have a quite aft CG - I seem to remember the C182 can easily end up on its tail if you switch off the engine. I'm still working on the C310 model based on the feedback I've received, so if anyone has further comments, let me know.

[Flightgear-devel] C310 Update
Hi All, I've been working on an update for the civilian Cessna 310R, and my patches are now available for review/check-in. The update consists of - new generic 3D instrumesnts for a throttle quadrant and rudder pedals - 3D cockpit for the civilian C310 (screenshot - http://www.nanjika.co.uk/flightgear/c310/cockpit.jpg) - Proper propeller control (keys n/N) - tidy-up of various files and directories - minor updates to the model. Patch files are available from http://www.nanjika.co.uk/flightgear/c310/ as follows: - quadrant.tar.gz - throttle quadrant to be placed in Aircraft/instruments-3d - pedals.tar.gz - rudder pedals to be placed in Aircraft/instruments-3d - yoke.tar.gz - update to the 3D yoke to make - c310.tar.gz - complete replacement for the civilian c310 (has dependencies on the above files.) - c310u3a.diff - diffs for the c310u3a to reference the new location for the panels There are a number of minor issues remaining: - For some reason I have minor alpha problems with the panel where the outside world can be seen through the bottom edge of some instruments. I haven't been able to get to the bottom of this. I'm not sure whether this is an issue with my graphics card or not. I don't see the same issue with the c182, which I used the same panel approach on. - The model is still a bit rough round the edges, as my modelling skills aren't very good. - As with the c182 updates I made, I've never been in the aircraft, so the updates are based on what I found on the web. - The nose gear intersects the bottom of the cockpit.

Could be a bit scary for the passengers :-) Hi Torsten, Thanks for the feedback. There are quite a few issues with the model which is basically unchanged from the previous release ( and nothing to do with me - excuses, excuses ... ). In particular a number of the surfaces are one-sided which causes problems when combined with transparent surfaces like the windows. I think it'll take a while before I'm really au-fait with modeling and manage to fix them all. Of course mixing up the mixture levers is completely my fault for not testing thoroughly enough... -Stuart ___ To help you stay safe and secure online, we've developed the all new Yahoo!

Re: [Flightgear-devel] C310 Update
Nothing to do with Stuart's work on the c310, but a tip on the fdm (jsbsim version): Move the CG forward a bit, at least a 10--15. (the correct CG location should be taken from the type certificate, which I haven't been able to find on a quick google) The plane flies a lot better then. (better stability and cruise alpha, when it's not flying on the stabiliser) This also puts a little more weight on the nose gear, so it steers better while taxiing. As it is now, the CG is actually aft of the lift. (AC_CGLOC is, if I understand it correctly, the CG location without the AC_POINTMASSes, i.e. empty plane?) A blind guess on the CG limits would be something around 15--35% of MGC perhaps? Outside the scope of the lift and drag definitions (due to alpha) tables -- as when stalled aggressively -- the plane behaves strangely, of course. But it's not certified for acrobatics. ;) ___ Flightgear-devel mailing list Flightgear-devel@flightgear.org http://mail.flightgear.org/mailman/listinfo/flightgear-devel 2f585eeea02e2c79d7b1d8c4963bae2d
