Spent some time tonight building the transmission for my Grand Hauler. Never used the book at all, just watched and paused this video. Much better watching this to build the transmission!! Kudos to you Bob for all these informative vids you post !!

[@HobbyconceptsLLC]

Glad it helped!

[@markwillis6106]

Thankyou so so much. Before this video, I was loosing my head before finding this. (4 hrs without any joy) but after this video, I built it in 1hr 15 mins

[@HobbyconceptsLLC]

Thanks! Videos do make it easier!!

[@anthonywitkowski1782]

Thank you for your time to show your videos

[@barrycheesemore2928]

Only just seen this, what a superb video, very informative.

[@JeffreyAu1]

I love your build videos Bob! So happy to see you posting again! I built a Rally Beetle last year and your videos were very helpful. Particularly the videos about how to organize the parts by type in muffin pans (I used old egg crates), reading the entire build manual prior to starting and the tips and trick on painting. I love that little RC car and it makes everyone smile when they see it.

Building a knight hauler. Just watched your full video thank you for helping me build my transmission

[@HobbyconceptsLLC]

Appreciate you watching!

[@seth8005]

Thanks for the highly detailed video like always!👏👏👏 I did not skip any second in this whole video.👍👍👍

[@Hi_Doctor_Nick]

The more videos I watch of yours, the more I appreciate the work you put in. This was brilliant. I bought my truck used, the guy never finished it and never had it running. This is my first 1/14 truck so it's all new to me, but the transmission felt odd. So I stripped it out and opened the case. Turns out it was put together wrong, and a spring was missing. I replaced the bearings and installed a Carson Poison motor while it was apart. Now after watching this video I'm thinking that brass bush might be the wrong way round, and I know I didn't glue the bearing in.

[@user-sn6lt9eb8m]

Thanks for doing these videos Bob. I have learned so much from you! Keep it up.

[@ericbrooks1562]

👍MASTERFULLY done, as always.

Awesome Build Bob!! Thank you!! Hope you are well!

[@socalsean3425]

Must watch prior to any build

[@truckerray7533]

Thankya for sharing the video! Ive got it saved for future reference. . . . .10-4👍🏼. I like the picture of the lady in the baground. She looks like my gramma Milton who 28 yrs ago!

[@mikeking2539]

Wow I wish I had found your channel before I made my Tamiya Scanis R620 6x4 truck. The ttramsmission gave me some issues. I managed to fix them, but still not 100% happy with it. And like you say here, it would be a lot of work to take it out and start again! Like your builds, keep them coming!

[@RCBirds]

Hi Bob great video. I couldn't see the ball-screw on my tablet in detail, but I think it's one of those Tamiya uses on many of their buggies where you can adjust the wheels. I use some 4 mm for our bird's doner. So if you find a buggy with this ball ends, find out the bag and you can order it. Bags are mostly cheaper than separate screws. If I find more informations I'll let you know.

[@michaelchristianson3179]

Awesome video!

[@asiabk9943]

[@ForDJWiz]

Thanks Bob!! Missed you!

[@HobbyconceptsLLC]

Yes, was gone for a month then super busy building trucks. Back now and lots of videos in the works!

[@timothyporter1632]

I really enjoy your build videos and your explanations. Talk about a dream job! As for me, I supervise technicians who repair and maintain light rail trains in the Los Angeles area, so that is also a dream job. Hope to see more videos! Really need more info on the MFC as far as getting the radio to work with the remote support legs.

Thank bob I’m about to start my grand hauler

[@HobbyconceptsLLC]

You will like my next few videos!

[@nathanburt9258]

That was so smooth when you tried it out. I just built my first one but it really loud and seems rough but I’m not sure what I did wrong. I’m building a ford Aeromax

[@HobbyconceptsLLC]

If it's rough something is wrong. Maybe motor pinion to tight?

[@jarekmace1536]

As far as the pinion spacing, I had a tech show me to use the receipt paper from the sale. He stated that after placing it in the gear path, it should not tear with a firm pull to extract it.

[@dogsergo]

Hello. If I understand correctly, the 55 motor is able to pull more cargo and consume less energy compared to the standard 27 motor? And he can also drive more carefully in hard-to-reach places and he has a lower maximum speed?

[@HobbyconceptsLLC]

That is all correct.

[@lynnfysh9418]

hi love your videos do you no the size digger i wood need for the traler is it the same scaile as tamiya 1,14 or is it differant thank you

[@lobilly]

Hi Bob - Can you please put a link for the motor you recommended over the stock one?

[@user-pc4bd1bj6j]

Great video. I have a question for you. Are you familiar with the Tamiya Toyota Hilux 3-speed 4 wheel drive transmission? I was hoping to replace my gears in that transmission with the aftermarket brass or metal gears for these transmissions. I'm hoping to be able to run a brushless motor in my toyota Hilux and not ruin the gears. I'm not looking for extra speed, just a smooth running trail truck that I can enjoy.

[@rockysoles3318]

I know you tell it like it is and I respect that I mitt I need help with building the truck I know according to your speech you saying there’s no room for margin of error

[@brianrutherford3681]

Do you paint the kits before selling them?

[@rockysoles3318]

And I noticed your turn easily on dime when you turn yours by hand but my was hard turn by hands?

[@Michigan_Tactical]

E clip, c clip... I call them fly away clips.

[@DomsRCandMore]

Great video! I have a used King hauler I'm going thru and rebuilding . I purchased a yeah racing 55T motor however I am confused on the pinion gear. The manual has 2 options 10 and 13 tooth pinion. Which do I buy? Also I got the MFC-01 but missing the vibration box can I buy that separately? Thanks again for the great videos! I subscribed!!

[@HobbyconceptsLLC]

On my personal trucks I often leave the vibration motor out, many builders do. They tend to shake the trucks apart.

[@khanhdj2537]

Cái đó có bán chứ

[@timhyde5352]

What do you think of the brass gears and metal synchroniser/ shift dog ..any good or waste of money....love the channel very informative.

[@HobbyconceptsLLC]

I have done it but frankly the stock gears and transmissions have never given me any problems.

[@DrDiff952]

Is the globe liner the newer style or older style. My only experience was with the Cascadia Evolution

[@HobbyconceptsLLC]

Older

[@richardcharlton8259]

Will the 55 turn motor run ok with the Multi function control unit or do I need to run the standard motor (rooster )

[@HobbyconceptsLLC]

Yes, work great!

[@lucascollaresbarreto]

Im building a Heavy hauler, there is a kit online that replace all the plastic gears with a brass. Do you think this upgrade is worth it? Thank you.

[@HobbyconceptsLLC]

I don't think it is worth it. I have done a couple but have never had the stock gears break ever, so not really needed in my opinion.

[@makewithmegma]

🔥💕👍

[@smitty1820]

Hello Bob, I watched this video as I was building my transmission. I ran it with a D battery as you demonstrated and had no issues. 1st gear to 2nd gear works perfectly, the problem I have is when I shift from 2nd gear to 3rd gear, I hear a sound like the gears are not meshing fully. Could this be in the transmission or in the differentials? I am thinking that I may not put enough CA on the bearing that is glued in. I would like any info you or others have that may have experienced this.

[@HobbyconceptsLLC]

If you run it with the case off you should be able to see what is happening. I doubt it is the bearings. If you are talking about it installed in a truck most likely it is a shift servo adjustment.

[@erynacamilla1626]

Question : does the truck transmissions and high lift have the same internals?

[@HobbyconceptsLLC]

They do not.

[@raycleary7090]

Hi Bob. Do you paint gearbox covers and, if so, what colour works best for you? Thanks Ray

[@HobbyconceptsLLC]

Sometimes I paint them to match the trucks. Also Tamiya offers an Aluminum Plated version that is really nice. hobbyconcepts.net/products/matte-plated-gearbox-for-tractor-truck?_pos=1&_sid=a82a7f35d&_ss=r

[@rockysoles3318]

Can you use grease axel for the gears and transmission?

[@HobbyconceptsLLC]

No, use a lighter weight grease like Tamiya ceramic grease or similar.

[@jasonwhite1001]

Great vid. My 770 manual says do not replace with ball bearings but you do. Any issues replacing and why might Tamiya state this?

[@HobbyconceptsLLC]

On the slider the bearings not only rotate but slide on the shaft. On some kits Tamiya says not to replace them with ball bearings and on other kits they do not. I personally always replace the bushings with ball bearings and grease the shaft in this area. Modern ball bearings slide back and forth fine, I have built literally hundreds of transmissions with no problems.

[@jasonwhite1001]

@@HobbyconceptsLLC thanks for the info…ball bearings it is!

[@tommyrescue82]

Can you use a brushless motor?? If so which set with Esc is best??

[@Rimrock300]

On can naturally, but it is very seldom used, as the brushed motors have no problem giving the power and speed needed to operate the trucks 'to scale'. The electronic units made specially for rc truck like these, containing both ESC, lights, sound, are only prepared for brushed motors. Some will use brushless motors, just for fun to drive them on a racetrack, use a one speed planetary transmission able to deal with the power and rpm

Hey Bob can you deliver orderes to india

Can you post links to the correct sized bearings?

[@Doug_Morgan]

My shift shaft in my King Hauler Black Edition is not like yours. It doesn't have the short spring, washer and E clip that you refer to as the hardest to install. The shift fork just slides on then a long spring.

[@HobbyconceptsLLC]

Yes, the Globe Liner and King Hauler come with the older style shift shaft. Works the same way just buiklds a bit differently.

[@nsvaluto48328]

will video work for euro truck kits also what is upgraded motor size and turns?

[@HobbyconceptsLLC]

Yes, all Tamiya truck transmissions. The Euro trucks have an additional post on the end of the transmission case but all the gears etc. are the same. All motors work. I generally iuse a 55 turn or so.

[@nsvaluto48328]

@@HobbyconceptsLLC is that same as 550 size ?

[@Rimrock300]

@@nsvaluto48328 They are standard 540 size. Many use 70-80 turn motors too. The point is to get something slower reving than the original racecar motor in the Tamiya kits

[@NutjobGTO]

I'm a bit of a motor snob, so I'm curious. Have you ever had the chance to go with a brushless motor?

[@Rimrock300]

Brushless is 'overkill' in these trucks, that are not supposed to move at any high speeds. Also not got the natural 'built in' breaking resistane as the brushed motors, down hill. Maybe workable with an advance ESC. Anyway, brushless as good as not used in these trucks. Maybe by someone that just want to have some fun, drive a rc truck like a race car. Which one naturally are free to do, I don't mind)

[@rockysoles3318]

I put my transmission together it wouldn’t turn barely but when I loosen the screws a little then it turns and run

[@HobbyconceptsLLC]

Something is wrong. My suggestion is to take it apart and start over.

Hiya Bob. I've noticed in the past you fully greased diff' and planet gears. So why only put a smile of grease to shafts and gears

[@Rimrock300]

In the tranmission there is more high rev gears than in the diff and similar. Too much loss of power if one grease up to much
