e205: HG P407 Central Steering System

[@RC4X4]

This by far is the best thing that could be done. Very cool. I need to upgrade mine now.

[@AMPROEngineering]

Thank you! IT is an old upgrade I have seen others do but they are complex and I knew I could make it simple.

[@johngubler1260]

Yeah!! I have been waiting for this upgrade ever since you did the review on the Bruiser Clone, Looking forward to what ever else you have planned for this truck

[@AMPROEngineering]

Thanks! I have a few more things coming.

[@TheRandomMechanic]

I just had the tabs snap off the 3d printed aluminum steering arm , wasnt expecting that , it did hold up for almost a year so thats pretty good , i was just driving on flat land and i guess there was a small bump that jerked the steering just right and snap

[@AMPROEngineering]

Wow really? Man that's a bummer. Mine has been gut but who knows what imperfections there are.

[@TheRandomMechanic]

@@AMPROEngineering Its ok i just ordered another one , hopefully it will be here by mid november

[@fahaka2003]

I added this servo mount this weekend. 1. I moved the shock mount behind the axle. Inserting the first screw second to the rear then using a scribe to align the front hole I was able to mount it without cutting or drilling on the frame. 2. By moving the shock mount the steering arm no longer made contact with the shock body. I didn’t do a before and after but I think the turning is tighter than original. 3. I took a crescent wrench and bent down the undergaurd diff cover as it was impacting the servo horn under fully compressed suspension. 4. Using a turn buckle I had for an 1/8 scale application gave me a tight fit with no play at all. Redcat Part Number 81204.

[@AMPROEngineering]

Fantastic information. Thank you so much for that. I will look into this

[@fahaka2003]

@@AMPROEngineering Any time. I'll be ordering a second set soon. It's such a huge improvement.

[@astridsactionrc545]

Really loving your upgrades for this truck. Definitely going to have to order these upgrades. I’m going all out with mine.

[@AMPROEngineering]

Awesome to hear!

[@tenhook726]

Can you throw down a complete hardware list for this mod? Ive purchased both pieces but would really like to get this installed correctly. Thanx. Y'all have done amazing work and your videos are a joy to watch.

[@AMPROEngineering]

I've gone ahead and updated the description with a small list of materials. It's just a few screws and a couple washers

[@djr01974]

Just relocated my steering servo with this set up. Wow what a big different.

[@AMPROEngineering]

I know, amazing how much play was there.

[@rodneyporterfield9257]

I did the samething but i mounted the servo on top the ampro piece because I found It kept popping the ball ends out of the steering link due to the angle of it. Had to cut a little off the frame but it works way better and is straight across and all around perfectly lined up. Has not broke sense then!💯🤪

[@AMPROEngineering]

Weird really? I have not had this issue. Glad you found a fix.

[@jamesswift4641]

Cool upgrades to an old truck👍👍

[@AMPROEngineering]

No kidding, ancient design and brand new model.

[@blkft]

Pretty cool. All the screws on my "Chruiser" have been a boogerboo to remove. Seriously torqued down WITH sometype of red threadlock. Its a fine line between stripping the hex out, snapping a ball stud or rounding off a hex key. I split a Tamiya wrench trying to remove one of the steering ball studs. But uts all fun still. :))

[@AMPROEngineering]

Really! Man mine had zero threadlock on anything. I see they heard customer complaints that cars were rattling apart!

[@blkft]

@@AMPROEngineering I know right? I guess getting threadlock depends on how late in the week when they're built. They gotta meet that qouta to get the weekend off ! :))

[@AMPROEngineering]

Hahaha! yeah you may be right.

[@steveclough6794]

great video Alberto and very cool model

[@AMPROEngineering]

Thank you!

[@gta97438]

Very cool, i just removed the torque limitor on my servo, but your solution is really better.

[@AMPROEngineering]

I didnt even think of that.

[@jb3161]

very nice upgrade,last year I decided to get some aluminum belcranks,, 1 for the clone and 2 for the old ones.. I think I had 1 I got some time back from rc4wd,but I could only find 1 on ebay.you pay some guy for it and it would be sent to you from somewhere else overseas, I watched it for a while but all at once they were being sold from several others, so I ordered 2 or 3 more,and they are still sitting in my Toyota parts tub lol..i go crazy looking for parts, and when I get them I put them in the correct 30 gallon tub of parts. anyway I wish you came up with that steering upgrade a year ago.

[@AMPROEngineering]

I also wanted to do that but was so tired of all the linkages. I just wanted them gone!

[@jamesmccabe8736]

I looked on your channel I didn't see if you came up with a mount for the original bruiser

[@AMPROEngineering]

No there isnt one. The motor mounts differently and it is much too large.

[@ShenRC]

😁👍That was a great idea!!

[@AMPROEngineering]

Thanks but I cant take credit. It is something people have done before but it is always a pain to make the servo fit so i just streamlined it!

[@kenstouffer8407]

Great video and much needed product/upgrade! I’m pretty sure I know the answer but I’m assuming there is no room for the added length of a 550 can motor?

[@AMPROEngineering]

Sadly no. It is tight!

[@silviamills5218]

Hi, I was out jumping my Grasshopper, when I landed upside down it broke the shock tower right off the chassis. I don't want to buy a new chassis unless I have to. Can I glue it back on? If so what type of glue should I use? Epoxy? Krazy Glu? Hot glue? Something else?

[@doylesmith8678]

MrRadRc , use super glue and sprinkle baking soda on it (it will harden instantly and is very strong)

[@AMPROEngineering]

Yes, superglue is the way to go. The baking soda helps also, I use it often. I would also reinforce it with some polystyrene or even a metal backer on the tower to make it a bit stronger but remember that you still need to clear the body

[@dozo4746]

Can I use the servo mount and steering arm on re-re Bruiser?

[@AMPROEngineering]

Doug, I wish I could answer that. Do not own one and though the parts look identical, I have no way to test it. I just dont know.

[@maranganii]

omg do some 3d printed aluminium hubs to allow fitment of standard sized wheels, you'd be a god among men, and I'd actually buy this and those and everyone would be happy

[@dozo4746]

Seconded!!!

[@AMPROEngineering]

So RC4WD makes them but they dont work given the axle width. They just shove the wheels out more. The only true fix is to replace the axles. I made an adapted wheel that will work better than anything I have ever seen but it still needs to go inward more.

[@fastyz400]

Thinking about your setup. Does the steering link hit the frame or springs when suspension is compressed?

[@SANDSCORCHER]

Another elegant solution 😎👌🏻👍🏻 Very much looking forward to your battery tray mod👍🏻 Will that be only for the clone car too, or is it likely to be a fit for the Tamiya rere?

[@AMPROEngineering]

Thank you! it fits the clone also, in fact that is where it is installed. I also have one for the original bruiser.

[@SANDSCORCHER]

I’ve not built my re-re yet so am not familiar with the battery tray. I know the gearbox is different to the 1985 car, but I’m not familiar at all with much of the rest of the variations between the 1985 car, the rerelease and the clone. Will you have battery tray mods available for all three cars ? 🙂

[@SANDSCORCHER]

Just realised how old this video is 😆👍🏻

[@josephcarrera3953]

Awesome job 🔩😎🔧

[@AMPROEngineering]

thank you!

[@catscan64]

Just ordered all your stuff from Shapeways. What servo and metal servo horn do you recommend?

[@AMPROEngineering]

Cool! I like Savox a lot. I honestly have no clue what version I picked up, its been a while. Something with higher torque is good. As for a metal horn, I hate to say it but I just randomly pick up versions on ebay. As long as the spline count is the same. Sorry I am not of more help.

[@RC4X4]

Can this part be dyed black or did you paint it? I think the steering link should be mounted on the top of the arm to look more level.

[@AMPROEngineering]

It is painted black. The production version has the servo 3 mm higher but if the link is higher than that there is interference.

[@josephsloppy6750]

Very nice will the up grade servo mount fit the orginal tamiya kits?

[@AMPROEngineering]

Not the vintage Bruiser. The motor is actually bolted to this part on the vintage Bruiser and I do not know about the vintage Mountaineer or the RERE cars. I would hope it did but I have no way to test it.

[@josephsloppy6750]

@@AMPROEngineering it wont work on the vintage mountiner either . it might work on the rerelease bruser\mountiner seeing the hg kit is baised off those two

[@AMPROEngineering]

OMG you are right. I was thinking about the battery retainer I made.

[@josephsloppy6750]

@@AMPROEngineering i was rite lol. You made a battery retainer i missed that video . check out the wpl c 34 km kit its a land cruser with all metal parts.

[@Nuts4fsr]

@@AMPROEngineering I fitted your servo mount to the ReRe Bruiser

[@Nuts4fsr]

Hi. I have an ReRe Bruiser, and have bought your front Servo mount and front hub spacers. Looking for a viable way of connecting to the steering hubs after snapping my stock metal plate and found your KZbin channel. Tried looking on Shapeways where I bought the other bits and couldn't find the part number you posted. Would you have a link?

[@AMPROEngineering]

So the only parts I offer for this is the main mount and the steering arms, both are linked in the description and I validated the links so those are both working. If I am missing something, I am very sorry. If you could email me at [e-mail] I will see what else I can do.

[@Nuts4fsr]

@@AMPROEngineering I saw the link in the video when I viewed on my PC instead of my phone. Will be ordering, after I finish my next Modification. Currently running Schumacher CAT XLS shocks all round. Will email you though

[@juswin24]

I checked the link and only white parts are available. How come no black parts?

[@AMPROEngineering]

Black costs more and has a rougher texture. The black is also dyed black from white so you are paying more for a part with a rougher surface.

[@AMPROEngineering]

Painting it with a matte black looks and works better than the dye.

[@ind23031980]

Can we use exsisting servo motor and use it with your ampro servo bracket?

[@AMPROEngineering]

Yes, this is just a standard size servo.

[@DukeGamingYT12]

Tracking number says mine should be arriving today. Can't wait to install it. Do you happen to have an extra instruction manual for the HG P407 or know where I can get my hands on one? Mine didn't come with one (or the decals) and I've had no luck getting the vendor to send me one nor can I find one online. Thanks in advance.

[@AMPROEngineering]

Cool! Let me know how you like it. I would assume you can locate one on ebay? I think the tamiya RERE bruiser should be close enough and you can get that as a pdf.

[@DukeGamingYT12]

Really enjoying the HG P407 after installing your steering system. Unfortunately, I just had to order another steering arm from Shapeways as the original one of yours I got snapped and I wasn't even running it that hard.

[@DukeGamingYT12]

Two runs in (and very mild runs) and the second steering arm broke in exactly the same spot. Very disappointed. The steering arm is just not strong enough.

[@fastyz400]

Thanks for the input Jason, I think, i will make one out of thin steel. Since the original piece is steel. Aluminum looks like it’s way to brittle. Going to go with a thin angle steel and using a Dremel grinding it to the shape of the steering arm..

[@BabyHuggable]

Can this be installed on the re-release Tamiya Bruiser?

[@AMPROEngineering]

I have never tried it on that truck but it may fit.

[@BabyHuggable]

Where can I buy one I need it for a old bruiser.

This is incompatible with the original bruiser. The motor mount is in the way.

Hi i need to replace the speed controller and steering servo and reciever any suggestions thanks on my hg p407

[@AMPROEngineering]

Any 2S Lipo speedo will work as long as it has 60A draw or more. As for a receiver, you need a 3Channel as well as a radio that accepts a 3 position 3rd channel. No clue about that one.

[@nealedmondson3191]

Why buy a servo mount when you can use a dremel and cut a rectangle out of the original brace in between the two top screws and make your own servo mount. Mine worked fabulous.

Eh, I hate chopping up metal. This took 5 minutes to design.

Hey there

[@KS-wt9gj]

Threadlock on plastic......NOPE

[@AMPROEngineering]

K S it’s a very common practice. There are even thread lock variants designed for different plastic materials since if a standard TL is used on Acrylic, it melts. For the poly jet material, it’s invaluable.
