View Full Version : Operating Motors for landing and takeoff and more

04-06-2014, 09:21 AM
Hi Guys, OK here is something a little different I am trying to achieve.

I have 2 x 45v Motors that have different size weights on pulleys that spin to reproduce the effects of a bumpy ride.

I have my eye on an add on shield servo board for the arduino, the plan is that when the throttle is applied for takeoff the large pulley motor increases in speed until take off where it slightly slows down then cuts out all together.

Then the small motor actiavtes when the landing gear up is toggled until its fully retracted thus producing a sound similar to the gear being raised.

Then vice versa as you come in to land,and hopefully if there is an fsx extraction, when the jet touches the ground the large motor switches on at a speed and also a speed according to your landing speed.

Does anyone have an idea of a sketch for this please.

Interesting concept Mike ,, sounds good. :)
Hopefully some-one will pop up with a way to do it.

Cheers ,, Jim

Hey Mike,

You just need to familiarize yourself with the Simconnect Outputs and the FSUIPC outputs. You can grab lists of each from a quick Google search. Here is some really rough thoughts just from memory

Motor 1:
If weight on wheels=1 AND Groundspeed > 20 kts or so
{map the motorspeed% to ground speed from say 20kts to VAPP (or thereabouts so on touchdown @ speed you start from max motor %) }
{Motor off}

Motor 2:
I cant remember if there is a gear in transit output so this could work

If Gear status not up AND Gear status not down {run motor varying %}

Just FYI though- there are easier ways to do this- just use a bass-shaker (tactile transducer) from the sound output. There are already programs like Accufeel which bump up the sounds/realism and LUA scripts which cause low frequency vibrations too for turbulence etc. Between them you will feel the bumps in the runway, engine vibration, wheels in transit, touchdown, turbulence in the air etc etc. This is what I use and is far more dynamic than actuators driven by specific systems IMO.
