I Built An EXTREME Upgraded Losi Promoto BEAST! (From Scratch!)

[@HighSocietyHobbies]

This is the coolest promoto build I’ve ever seen man you killed it 🤘🏽 what an absolutely epic bike build!

[@DoRC]

Thanks :-) It was a lot of work but it was a lot of fun!

[@bobbjorkner7140]

Every time i watch one of your videos, I want to go out and DO RC! there is a lot of interesting engineering, such as the floating disc. I've never had an RC bike, but the Losi design and excellent performance had me convinced.

[@DoRC]

Yeah it's definitely worth giving a try. It won't be for everyone and it does require learning some new skills but it's fun.

[@Nerm78]

Insane build! Definitely the best one yet on one of these bikes!

[@DoRC]

Thanks yeah it's pretty much as upgraded as you can get!

[@magnusstone]

12:59 the amount of golden nuggets you drop in these videos is kind of insane. How else would one know to use dry lube on a servo saver? Edit 14:56 I never even thought about threadlocker dripping into bearings!!

[@DoRC]

Yeah it's something that you need to be aware for bearings as well as things like kingpin pivots. I've seized up kingpins before with threadlocker.

Absolutely beautiful video, brou. from spending 30-40 years racing motocross this rig was right up my alley. i haven't put to much upgrade to it other than swingarm and linkages. some day ill do what you did. maybe this winter. awesome video "Do". i learned a few things. have fun.

[@DoRC]

Glad you enjoyed. It was a pretty long project but definitely a lot of fun :-)

[@Ryan-bk3zx]

I would have left the inner piece off as well instead of ripping back apart. Then it woukd bug me for 2 weeks before I take it completely back apart and put it on in the end. Lol hopefully you're at terms with your decision. Awesome build man. I'm so close to ordering one. Just got the losi db pro after the dbxl and really happy with the losi quality and build.

[@DoRC]

Yeah I already went back and fixed it :-)

looks good!! even better without the plastic

[@DoRC]

I agree. Had to add the plastic to protect all the pretty parts though :-)

[@aussiedigger1441]

Alcohol to clean threads is a must in a rc helicopter! Bearing retaining compound would be great to use for the bearings in steering stem!

[@DoRC]

Yeah if it's an important screw it's definitely best to clean it.

[@GreatLakesRC]

Definitely a tank of a promoto 👍 Those CF wheels are so nice 🤩 If I ever get one of these I think the wheels would be my only upgrade. This bike is so complex! Im sure you learned alot by building it this way.

[@DoRC]

That's exactly why I did the build. I really wasn't that familiar with the platform and wanted to learn as much as possible!

[@VS666]

I haven’t done any research on batteries yet, I’ve had my bike since Christmas. The stock battery lasts like 3min on the sand 😮‍💨 but I love this thing it’s such a head turner

[@mrk8212]

Cool vid, thank you. This is the reason I haven't bought a Promoto yet.. I know I would buy all those upgrades and end up with a small fortune in it. Like all my other RC stuff.

[@DoRC]

Upgrading can definitely get expensive! Thanks for watching :-)

[@boduke9428]

That's definitely the most mods I've seen on one. You gotta at least give a ballpark on what this cost. Talbot put $900 in upgrades on his if i remember correctly and didn't go nearly as deep. How many rtr ones could you buy for this total amount? It looks great regardless. I've never wanted the Promoto but I've almost bought a RZR Rey a few times. I just wish it was bigger. I think a SBR 2.0 sized RZR Rey would be a lot of fun.

[@DoRC]

You're going to be looking at around 1,300 for what you saw there.

[@biohazard9639]

Damn..

[@alantaylor353]

I use a lot of alloy wheels on my touring cars & you'll find it adheres well enough, but not as well as plastic rims. It won't stay glued as long, you'll really need to get into the habit of checking your glue bead regularly & redoing it from time to time.!

[@DoRC]

Yeah I've already had to reglue a couple of times.

[@Deezarehairy]

I've given mine a flogging Apart from a few part's like that front plate that breaks and the linkages. Replacing the plastic part's is a back step. Plastic bends and goes back to shape. Metal bends breaks. And plastic is lighter. The bike's heavy as it is. More weight means less performance.

[@DoRC]

Yeah a build like this isn't necessarily designed to create the most efficient end result. This is an extreme upgrade mostly just to showcase what can be done. I would not really recommend anybody do this unless their goal is to have the most upgraded promoto :-)

gluing on aluminum usuallly gives way which is why most aluminum wheels are beadlocks but in this case seems to work just fine. overall this bike build looks great I wonder if they will sell aftermarket panels that you can paint as if this entire bike would look cool all black.

So far so good. They do have blank panels and a bunch of different colors I think black is one of them.

[@SwiftSystems1]

Thank you for sharing this video. I would be delighted to make a donation if possible. I am new to the RC Motorcycle hobby and have been unable to fully enjoy my Promoto due to some unforeseen circumstances. When I pre-ordered the bike and upgrades from the Losi/Horizon website, it did not include any of bike upgrades and electronics I had expected. Additionally, their website did not provide clear information about what was included in the shipment, and the bike arrived separately. As a result, I have only been able to take it out of the box and turn it on.

[@DoRC]

I appreciate the offer but I don't do this channel for profit. It's not even monetized so no need for donations. As far as what came with it what exactly is missing?

You'd be surprised about c rating. It's pretty much always a lie and there really is no such thing as a 100 c battery. I recommend just going with a good quality brand such as SMC. You're going to get the best performance out of something like that even if the label doesn't have the highest c rating.

There's a 3D printable piece you can either make yourself or buy that goes between the torso and the legs which reduces that tendency.

[@toolbaggers]

Technical jargon - springs absorb shocks. The thing with the oil and pistons dampen the oscillations of the spring. This is why certain people correctly refer to them as dampeners instead of shock absorbers. Don't get me started on the differences between struts and "shocks." They are different things!! Hinit - the Losi has front struts while the rear (and tiny 3rd front) "shock" is merely a dampener.

@@DoRC tell me you didn’t look without telling me you didn’t look…

[@gboulter]

Most upgraded 🤣. The glue needed on alloy to rubber is Loctite 480. The full size AGFrc is a perfect fit the one you had needs some spacers and two of the slots extending slightly. No damping fluid in the headstock. There are upgraded drive sprockets but Vitavon not Treal so I guess you ignored them as not the sponsor. The silver and black springs are the same weight one is wound left the other right so twisting cancels itself out the center part rotates with travel.

[@DoRC]

According to the MDS loctite 480 is CA glue with rubber in it. Might be more appropriate for this particular application but standard CA glue is rated for gluing rubber to aluminum. That's cool. I didn't have the full size AGFRC servo so wasn't really something I could test during the build. I'm sure there are plenty of servos That fit though. I did a quick search before the build and didn't see any sprockets but sometimes the vitavon stuff can be difficult to find The Black springs have a smaller wire diameter than the silver ones so at least by my measurements they are not as stiff. It may be a small enough difference is to not matter but at least again by my measurements there is a difference. Thanks for watching :-)

[@larrytemen4789]

Rear spring is too heavy. Drop it down one

[@DoRC]

It might just be too much preload. I had it cranked down pretty hard

[@toolbaggers]

The number of coils in a spring can be used to compare stiffness if using the same brand of springs from a manufacturer that only uses one spring material to make all of their springs. This ignores things like progressive vs linear and dead coils that merely affect ride height. 6 drumsticks from KFC is a lot more chicken than 10 McNuggets from McDonalds but is a lot less chicken than 5 chicken breasts from KFC.

[@DoRC]

Correct. If you watch the video you'll see that before I start counting coils I measure the diameter of the wire and ensure that the wire is the same diameter on all of the springs I'm comparing.

[@speedteamhpi]

Overkill bigtime . Handling dropped dramatically you can see that in the video. All this aluminum stuff is nice but it definitely does not increase the handling at all at any point the bike was designed and developed for six years to be able to perform the way it does adding weight does not help. Maybe a little bit in the key areas as far as the lower center of mass. but now the gyro has to work twice as hard to keep all that weight stood up you can see it when you turn the bike it kept on the wobble. you might be able to adjust a little bit of that out with the gyro but again it's worth doing twice the work that it was not intended to do. you can also hear the motor over reving .. i bet temps where high Don't get me wrong this makes the bike look killer, but you're basically built a paperweight or parking lot pounder. most of these add on are for aesthetic purposes.

[@DoRC]

Where as this build was done more as a showpiece than a practical piece There are some things I don't fully agree with. First of all stability actually is reduced the lower the center of gravity on two wheeled machine. The more weight you have up high the more inertia it has so the less tendency it has to change direction. As far as it wobbling around that was actually me not the bike. I'm not that familiar with driving these and trying to drive film and do things like jump really aren't easy. The bike itself was actually pretty darn stable. Didn't really notice any issues with temps either as it really isn't that much heavier than the stock bike as I showed when I weighed it. Overall I would definitely not recommend all of these upgrades to someone as like you said most of them aren't actually necessary but I don't think it really changed the dynamics of the bike as much as you would assume.
