FSC 737 Motorised Throttle Teardown

In this video, you will witness the first part of the two-part Motorised 737 Throttle teardowns. The Pro version from FSC is the unit being showcased, which is an outstanding piece of engineering and electronics. Our goal is to restore both throttles to their working condition, as they are required for a commercial sim centre located in the UK. Have you ever wondered how all the workings are accommodated in such a small space? This Teardown video will hopefully answer that question for you!

I like the FSC attention to detail, the green primer colour on the internal metalwork. I doubt this is essentially needed on the assembly, but it shows they've looked at Boeing TQ's and have committed manufacturing time to something you'd only see when you open it up.

[@mortimerduke3645]

Fantastic tear down! It's easy to see why they cost so much. The amount of engineering and complexity is significant. I tore down my older RevSim TQ (i.e. CockpitForYou) and completely rebuilt it from almost the ground up. When I had it all apart I remember thinking "Oh man, what have I done?!" It's overwhelming, but bit by bit I brought it back to life. Like you, I'm fascinated by the different ingenuity used solve the same complex problems. Love the work you do and appreciate your contributions to the community!

[@balaramalan]

Well done Karl, I had been patiently waiting for this video. Keep up the great work. Thank you

[@helimech8152]

Hi Bala, There's a lot packed into this unit and it was fantatsic to see how well put togther it was. Certainly a sturdy bit of kit!

[@alexju6181]

Great video! I had to watch the video twice because the first time I watched the object that was behind your back :) So many things have been added since the last video... I build the sim almost synchronously with you, as soon as you publish something new, I implement it straight away. Thank you for your engineer artwork and videos!

[@uprzejmypiesio6875]

You are truly amazing Karl, your channel is really helpful for those starting in cockpit building

[@TakeNoneForTheTeam]

I wish you had 10x the content posted. You have an amazing channel! Thank you so much!!!

[@richardcranium9887]

The cockpit For You throttles are more like the actual aircraft, however, they are renowned for a total lack of support. You cant push the parking brake off on the aircraft, it only releases with pedal pressure. People get stressed in simulators, and the aircraft, they often start 'swinging' on the reversers before the locks have released, thankfully the aircraft throttle is solidly built! I would also say now Ive seen the inside of the FSC throttle it appears better engineered than the CFY throttles. Great video as always.

[@balaramalan]

The CFY TQ has less than ZERO support. I have one that I bought since 2015. I had a chat with Karl on how I can configure it to work with a better software and hardware. I am awaiting the CFY dissect video soon.

[@Aidan-ex7ot]

Can't wait to see the sim fully finished

[@helimech8152]

Me too! Just two panels to go in this section the MCP & EFIS

[@B747-4OO]

Really clever mechanism! Remarkable, that users manage to breake the parts with brute force🙄. Very interesting video, Karl!

[@helimech8152]

Thank you! Its great to see you are still here and following along! I'm currently upgrading the some of the parts, but i feel they way the reversers are made, they will always be weak due to the lever forces involved.

[@B747-4OO]

@@helimech8152 I'm sure you'll make the best of it. Good luck!

[@fsprimo]

nice to see you excited with this toys. what an peace engineering those units are!

[@hkr4life]

amazing as always

[@helimech8152]

Thanks again!

[@billnelson3732]

Very interesting!!! Some clever parts in there, genius ideas!

[@helimech8152]

Hi Bill, Very clever and some serious thought has gone into this unit. I wonder how many prototypes it took to get it to this level!

[@billnelson3732]

No doubt about that!! Many prototypes and sleepness nights staring at the ceiling wondering "...what if I"

[@valtercastoldi4124]

Great karl, thanks. Very interesting, I too am waiting for the ending, with your vote.

[@TCovey210]

Optical encoders on the trim wheels.. Bingo! now I know how to set the turn ratio of trim wheel to trim pointer and actuator signal.. Thanks Karl my Beech 350 simulator will be perfect.

[@pascal-antoinducardus5074]

....an absolutely phantastic video mate !!! Based on this video I am evaluating to buy this TQ from CPFLIGHT or FSC.... PHANTASTIC JOB mate. Hopefully to see you again in Lelystadt next year in March...!!!😊😊😊

[@helimech8152]

Glad you enjoyed it I am hoping to be in Lelystradt

[@pascal-antoinducardus5074]

The more I see your video the more engineering improvements I will do when this TQ will arriving... BUTTON, SWITCHES, PARKINGBRAKE and LIGHT, BACKLIGHTING....

[@pascal-antoinducardus5074]

it is possible to see more about its backlighting performance??? ❤❤❤

[@pascal-antoinducardus5074]

Can you maybe meassure the size of the throttle itselfs ? OEM TQ THROTTLES are 18,5 cm high... THANK YOU !!!❤

[@juliocarvajal3394]

Great videos! very nice creations, you are a very talented person.

[@GastonDwarvenPilot]

Thanks for sharing Karl!. Great content!

[@helimech8152]

Glad you enjoyed it! It certainly opened my eyes to how a professional unit is designed.

[@randysteven88]

So when will we see a MTU v6 with tricks learned from these units? 😄

[@TheFlyingSPR]

Thanks a lot karl very very very interesting video a lot of information

[@lokmanwong7786]

Finally …been waiting so long😂

[@helimech8152]

Time passes so quickly and I was very suprised it has been this long since my last video release.

[@lucriche6357]

Thanks a lot, this document interested me a lot. Having always wanted to make a throtttle for 737, I knew the complexity. Quick question: did you reassemble the device?😅

[@abuassrarassrar6079]

Hi very good video thanks . But how about cockpitforyou did you started or when you going to start with it. Thanks for the sharing. 👍

[@sivoltage]

Are these devices used to train real life pilots? If not they are very sophisticated for a consumer simulator. Quite amazing and fascinating to see these broken down.

[@andysmith8649]

Hi, I have printed a few of your 737 parts and i like your cad style. Could you please share the secret to getting the sim instrument panel to be removed from the forward view in msfs2020? in FSX its a simple right click.

[@angelocosma1007]

Is there a part 2 of this? Was curious about the reverse thrust mechanism, the repair, and the comparison to the other vendor TQ.

[@helimech8152]

Waiting for parts (PCB). I don't have much room in tis workshop, so i need that one finished before I can bring in the new one.

[@2oqp577]

At 34:23, that is called a Belleville washer. Often used in gangs.

[@helimech8152]

Gosh, i had forgotten that! I remember learning about those back in my apprenticeship days almost 30 years ago.

[@oliver9089]

Oof, that's a complex little machine!

[@helimech8152]

It was! A great bit of engineering.

[@zak3518]

Hi - I’ve been using FSC motorised TQ for about 4 years from new. Although it’s well made, there are few design deficiencies in my opinion. Firstly, the parking brake lever is too lightweight and hasn’t got the right kind of resistance when operating. The thrust reverse levers also don’t have a solid feel and there is too much play in the linkages when operating. Lastly, the trim wheel gearbox and motor is way too noisy and far from perfect in reproducing sound anywhere near like the real thing, considering how expensive the TQ is. Be interesting if you can improve these deficiencies during your rebuild.

[@helimech8152]

I have come to the same conclusion as you on the first two points. The thrust reverse mod is nearly done, but the design is flawed by lever pivot point. Your always doing to be able to put more force in, than the parts can take. The parking brake would need a complete redesign to bring that up to a good standard. I'm just going to rebuild that and get it working again. As for the trim wheels, I need to rebuild that to see what they actually sound and feel like.

[@steffgrunwald8881]

Nice one Karl! Do I see a Motorized Throttle v6 in the design stage ?

[@helimech8152]

That sends shivers down my spine just thinking about redoing the throttle. The last one took nearly a year! time will see"

[@sky173]

I'd almost die for one of these, but they're just too expensive. Maybe when I win the Lotto, lol. I'd love to see what the gear ratio is between the trim wheel to trim indicator in the real Boeing cockpit. I can build my own, but I just need the numbers (and a lot of time in the shop).

[@_PSantos]

I´m seriously thinking about sending you my A320 throttle for you to check it and if needed, fix it. HAHAHAHAHA

[@AviatorPanels]

you absolutely should 😊

[@SWAFanPilot]

What's the best throttle under $1,500 or $2,000?

[@BD_M4220C]

the CFY throttles will move stiff unless they are connected to power

[@helimech8152]

Hello and thank you. That makes sense.

[@dotnetdevni]

problem is ur not finishing each segment in videos would rather have longer videos showing completion

[@helimech8152]

Hello, This was a tear down as marked in the video title. Not the repair. Kind regards, Karl

[@windshearahead7012]

there is no way you put this back together

[@helimech8152]

That was always a worry! but its back together, now just waiting on parts (PCB) to make it operational

[@juliocarvajal3394]

Do you have any parts for a Beechcraft B200 Sim?

[@helimech8152]

Not yet, but I really would like to create some parts for it

[@forbiddenera]

I insta clicked this thinking you were talking about actual throttles, not throttle controllers. 😢
