Saab JAS 39C Gripen (WiP)

26.3k BRuthless  8.2 years ago

Here's a first version of the Saab JAS 39C Gripen I am currently working on for you to try out.

Airframe, cockpit and wings are pretty much done, it's only missing airbrakes, weapons, pylons, main gun and details.

I would suggest taking off as quickly as possible, as it doesn't like driving fast on the ground.
You have two afterburner stages available, which are activated with AG1 and AG2.
After take-off you will probably notice the nose dipping down a bit, that's why there's pitch-trim activated by AG4 and controlled with the VTOL-slider.
For extra stopping power while landing the canards can be angled 60° downwards by activating AG3 and activating the brakes (don't do this up in the air, but you can already activate it just before touch-down).

The canards seem to vibrate a lot and make strange noises, but that's nothing critical.

Feedback is appreciated!
Enjoy! :)

    @Wakescar No vibrating canards on your devices? Im on PC with maximum settings and I can see and hear them when rolling and pitching. It gets dramatic when going full speed and doing extreme maneuvering, but atleast I could get them from breaking off and exploding the aircraft by nudging them one step away from the intakes. :D Thanks for the advice with looking for spare parts, that could be the issue, though I think it's caused or atleast intensified by the design with the engine sitting above the CoM and pushing the aircraft downwards. I had many problems with those in SimplePlanes already, sometimes even leading into crashes before I was able to take off. :D

    Little hinks like your slight auto-yaw, I've found are usually result of "spare parts." i.e. Fuselage parts double within themselves, random other mirror glitches or something I dragged into the mix myself by accident.
    One way to troubleshoot this:
    • Remove your cockpit block
    - Entire build should turn grey
    • Zoom out a bit
    • Grab and move your entire aircraft completely away from its position in the editor
    This should leave behind any spare parts.

    @BRuthless I'm never completely satisfied with anything I build either but you can't help being your own worst critic. No vibrating canards on my phone or iPad.

    By using the stall speed of ~100 MPH and the brake function of the canards it can land very quickly. I'll try USS Tiny, even that shouldn't be a problem. :D

    @Wakescar I'm not that happy about the vibrating canards and the tendency to turn left when going fast on the ground though. :D Also it's hard work getting the shapes right on this one. Maybe it just needs some more CoM adjustment, but it feels like the problem is somewhere else.
