- I have attached servos to my throttle handles to make them motorized.
Further more I show how I have made the fuel cut of and attached potentiometers.

you are too modest Peter-your work is very clever and well thought out.
I am a recently retired B738 Captain with 14,000 hours PIC-my recollection is that the Engine Start Levers ( in effect the fuel levers) operate via a cable to the MEC/spar valve-opening and closing them around halfway between cut-off and idle positions.
The detent positions at either end of travel are safety features to prevent inadvertent operation of the lever-especially shutdown!! Note that 600-900 models have an blue eng.valve closed and a blue spar valve closed light per engine-the earlier model B737 have only the one blue fuel valve closed light.
Your pedestal configuration looks terrific-I would not worry about the micro switches being activated at the end of engine start lever travel. Thanks again-my son and I will be attempting an upgrade to his home flight sim. aided by your great ideas.
awesome peter keep up the good work
I think its activated as soon as the leaver reaches the top. The pull out motion does not move the cables leading to the switches deeper in the throttle stand on the real one. I saw a video where a guy was modding one. It looks good though, every time i try something mechanical I fail.
Awesom video!!!!!!!!!!!!!!!!!!!!
correction to my last comment-shows how memory can be suspect sometimes!!
I have just checked my FCOM and both B 737 types have electrically operated FSOVs powered via Battery/Hot battery bus sources-therefore available on battery power only should all generator power be lost.
As to when these switches are activated by engine start lever movement my guess is not at the detent positions in both cases.
The aeroplane is quite restricted on standby power-barely 30 minutes electrical endurance-unless an additional battery is installed-fuel system is especially degraded-no fuel pumps at all so gravity feed wing tanks only-with possible thrust deterioration above 30,000 feet-and all centre tank fuel unuseable .
Enjoy your time away
Regards
Awesome so far! I've got a question! How do you programm all those external knobs to the sim after all? Special Software? FSUIPC?
Thanks in advance!
its a 600 bucks software called 'Prosim'
Where did you get the dimention and diagram
can u share with me what card u used.
Nice Job Peter, I have a question: What's the name of the potentiometers that you used for both levers?
+Christopher Bermeo Guartán I found them on eBay. Can not remember the name/brand. Perhaps it was Alps og Alma. Just the longest 10k I could find at a reasonable price.
Nice work! I have a question for you. Does Is this lever hardware so haevy for the servo motor?
+meraki I use "heavy duty" servos with metal gears. So far they have passed the test.
Only problem has been the plastic arm that you put on top of the servo. The plastic teeth has been teared all off my the metal shaft on the servo. So you will need a metal arm.
Can you send to me your .INO file? amarildocunha@hotmail.com
as pessoas só sabem vende esse projeto mas não são capaz de mostra a instalação do painel MIP 737 com o SIOC
Can I buy this???
How much would a motorized throttle cost, if you made it for me? :D I'm in Denmark too.
I am not making any! :-) It is too much work and I would like to use my time on my own project. Starting to manufacture would also mean I had to ensure the quality and have a warranty. I supply ideas - and they are for free. :-)
I have only recently started to collect or build my the parts//components for my 737 cockpit set up what I would like to find are full size drawings for the throttle leavers , if you have a set of said drawing and you could let me have a copy I would gladly reimburse you for any expenses that you may incur , or maybe you could point me in the correct directions for obtaining some of the same, a great many thanks for taking the time to read my mail , sincerely yours V.L.A.P ( lonewolf 45 )
