*Updated 2-25-12* New to Micros/Scalers First Project Trail Trekker Hummer Build Just got a Trail Trekker from my wife for Valentines. I have a ton of ideas for this yet but I'd like to think I have gotten a bit done so far. I will post some stuff I have done and add more later as this progresses. I actually got a lot of ideas from a project I found on Scale4X4. You can find the original here Losi Micro Crawler Hummer H1 - Scale 4x4 R/C Forums --Here are a few Pictures of my stock rig so you can get an idea how far I've progressed. http://i1074.photobucket.com/albums/...PreWork1-1.jpg On the rocks. http://i1074.photobucket.com/albums/...hTrailer-1.jpg On the trailer I hope it will eventually tow. --I got a new Hummer body from a Revell snap together model. I saw a few other people who have also used this model as a base so it should look familiar. http://i1074.photobucket.com/albums/...rChassis-1.jpg Here is my new body sitting on the stock chassis. --I wanted to make a little pickup bed so I used some Styrene Sheet and some green putty to fill the gaps. This is my first attempt at working with anything like this so be nice. http://i1074.photobucket.com/albums/...TruckBed-1.jpg |
New to Micros/Scalers First Project Trail Trekker Hummer Build I borrowed heavily from another build I read about for the next few steps, but after I get it running again I have a few ideas of my own to take this project a few steps further. --I ordered a micro crawler chassis as a base to connect my suspension links. I had to trim it a bit but it fits like a glove. http://i1074.photobucket.com/albums/...omMockUp-1.jpg I haven't put the shocks on yet, and this isn't secured yet. http://i1074.photobucket.com/albums/...upNoBody-1.jpg Here is sits with the shocks on the stock wheels and tires. I still haven't mounted electronics completely or secured the two pieces. http://i1074.photobucket.com/albums/...forScale-1.jpg Here I put the body on top to see how it lines up. I put the pen there for scale. --At the same time I did the pickup bed I put some backs on the seats. I borrowed this idea too because I hated how the seats weren't complete. http://i1074.photobucket.com/albums/...PrePaint-1.jpg |
Re: New to Micros/Scalers First Project Trail Trekker Hummer Build Looks great keep us updated, I dig the white walls on the trailer reminesant of Back to the Future 3 Delorean haha. |
New to Micros/Scalers First Project Trail Trekker Hummer Build I got the electronics wired up and secured the crawler chassis to the model chassis. I switched the connectors to micro deans just for ease of use. http://i1074.photobucket.com/albums/...ntNoBody-1.jpg From the bottom. http://i1074.photobucket.com/albums/...ntNoBody-1.jpg From the side. http://i1074.photobucket.com/albums/...ntNoBody-1.jpg From the top. --I mounted the upper shock mount directly to the model chassis. The front section is a perfect fit for the ESC as well. I secured the two sections with a liberal application of Amazing Goop(AKA shoe goo). http://i1074.photobucket.com/albums/...onMockUp-1.jpg Here is a test articulation with the mounted and wired chassis. --The I started preparing the body. I drilled a hole in the pickup bed to run wires as I plan on putting the battery in there. I will probably make up a tonneau cover so they will be hidden. I also primed the body and seats. http://i1074.photobucket.com/albums/...tsPrimed-1.jpg --During the preparation for the wheel weights I had some technical difficulties and now have no wheels or tires. I tried freezing to remove the glue, and then when that didn't suffice to break the glue I attempted to back them off. Well I guess I did it a little to hot because they melted. The wheels and tires are now piles of goop. So I ordered a new set of RC4WD aluminum beadlocks and Mickey Thompsons. |
New to Micros/Scalers First Project Trail Trekker Hummer Build I started working on my lighting today, which brings me up to current with this build. I made a custom circuit with an on/off switch to run a set of headlights and taillights. I will run them from a very small 1s lipo I took from a micro heli I have. The circuitry and battery, as well as the Losi battery for the car will all be stored in the pickup bed. http://i1074.photobucket.com/albums/...itDetail-1.jpg Here is my circuit. http://i1074.photobucket.com/albums/...kingTest-1.jpg I was testing the circuit using an arduino as a power source. The finished one will use a 1s lipo. http://i1074.photobucket.com/albums/...tBattery-1.jpg I wrapped it up nice to protect the circuit. I won't mount it until I can finish my light housings, but it's coming soon. I also ordered some threaded rod and the other pieces I need to extend the front out a bit. As it sits right now the front wheels are too far in even with the trekker links. |
New to Micros/Scalers First Project Trail Trekker Hummer Build I think one of my posts got lost in limbo. I secured the crawler frame to the model using Amazing Goop(AKA shoe goo). I also got the electronics mounted and wired up, in the process I replaced all the losi connectors with micro deans. http://i1074.photobucket.com/albums/...ntNoBody-1.jpg The bottom of the chassis to show how its mounted. http://i1074.photobucket.com/albums/...ntNoBody-1.jpg How it looks from the side. http://i1074.photobucket.com/albums/...ntNoBody-1.jpg Here is the top view. I tried some CA glue first which discolored the plastic a bit but ended up using some amazing goop. It's rock solid once it sits for a day. http://i1074.photobucket.com/albums/...onMockUp-1.jpg To show the articulation. --I also started prepping the body. A mishap trying to remove the tires from the wheels required me to order a new set, so I have some RC4WD aluminum beadlocks and some mickey thompsons coming. http://i1074.photobucket.com/albums/...tsPrimed-1.jpg Primed up the body and the seats. |
Re: New to Micros/Scalers First Project Trail Trekker Hummer Build where did you get the trailer? |
Re: New to Micros/Scalers First Project Trail Trekker Hummer Build Nice Work, The trekk's are awesome, well except the motors-ha. U should drop one of those DDT's in there. A Performing Scaler- after all, its a Hummer!! |

--I should be posting a bit of an update on the project this weekend. Waiting on a few parts still and getting the paint finished tonight. |
Update Time!!! Time for some well earned relaxation. I have put a ton of work into the micro this week and I am pretty much ready for a break. I will update y'all with where I have gotten so far. --I got the paint done first. http://i1074.photobucket.com/albums/...r/IMG_0737.jpg Black coat finished. http://i1074.photobucket.com/albums/...r/IMG_0741.jpg http://i1074.photobucket.com/albums/...r/IMG_0742.jpg And the final red coat has gone down, as well as hand detailing with black and silver. Also I have drilled out the space the headlights. http://i1074.photobucket.com/albums/...r/IMG_0744.jpg I like this pic because it shows the scale of the detailing I did. I think it turned out pretty good. :) |
Interior I did a little detailing on the interior. Nothing major, but I liked how it turned out. http://i1074.photobucket.com/albums/...r/IMG_0738.jpg First I used a bit of foil tape to make up some metal doorpans. http://i1074.photobucket.com/albums/...r/IMG_0740.jpg Now I've gotten the seats(which I had to trim to fit with the chassis bracket in there), the dash, and the steering wheel in. I also put the windshield in at this point which you will see in another pic. http://i1074.photobucket.com/albums/...r/IMG_0748.jpg http://i1074.photobucket.com/albums/...r/IMG_0755.jpg To mount the body I used a couple small strips of Velcro. -- I also got my new suspension links made up to stretch the front out a bit. http://i1074.photobucket.com/albums/...r/IMG_0745.jpg You can see that the front sits out far enough now. http://i1074.photobucket.com/albums/...r/IMG_0756.jpg I also installed a dual rate spring setup using the blue and red springs from the first gen Xmods spring kit. I actually had one of these just sitting around. I had to beef up the springs because of the heavy upper body. |
Lighting I put quite a bit of work into the lighting on this build. I wanted to keep the lights as scale looking as possible and also keep them hidden as well as I could. I have previously shown you the lighting harness I made for this build. I have now gotten it working using battery power. I reused a battery from a micro copter since it had enough juice for the bigger 5mm high output white LED's for the headlights. http://i1074.photobucket.com/albums/...r/IMG_0754.jpg Here's a closeup of the battery I'm using. http://i1074.photobucket.com/albums/...r/IMG_0753.jpg A picture to show it functioning with the battery. --Next I had to devise a method of attaching the lights, but at the same time I needed to make them scale looking. http://i1074.photobucket.com/albums/...r/IMG_0746.jpg I used some .030" styrene to make a couple of front headlamp housings. In the picture you can also see the front headlamp lenses that I trimmed to use. For the rears I am using some servo horn adapters I found in my spare parts. http://i1074.photobucket.com/albums/...r/IMG_0751.jpg After painting them silver on the inside(for reflectivity) and black on the outside I glued the rear housing to a thin red transparency. After it had dried I was able to cut it free, thereby making a taillight lens. |
Lighting cont. Next I had to attach the housing for the lamps to the body of the vehicle. http://i1074.photobucket.com/albums/...r/IMG_0749.jpg The fronts glued into their respective places. http://i1074.photobucket.com/albums/...r/IMG_0750.jpg I've gotten the headlamp lenses attached. http://i1074.photobucket.com/albums/...r/IMG_0770.jpg Here are the rears. I made the holes I drilled big enough to just set the housing right into them. They actually look very similar to the 1:1 now even though they are just a little more rounded. These turned out great in my opinion.(for the quick eyed of you I am sure you already spotted the fruition of another part of this project I haven't shown yet.) http://i1074.photobucket.com/albums/...r/IMG_0771.jpg Using my friend Amazing Goop(shoe goo), I have attached my front headlamps into the housings. http://i1074.photobucket.com/albums/...r/IMG_0772.jpg I did the same for the rears. The tape is just used to secure them in place while they are drying. --And now to see the fruits of my labor or this lighting project. http://i1074.photobucket.com/albums/...r/IMG_0773.jpg The rear lights. I will explain the bed cover in another post. http://i1074.photobucket.com/albums/...r/IMG_0775.jpg And the headlamps. I tried to take a picture from the front but they are so bright they introduce too much glare. http://i1074.photobucket.com/albums/...r/IMG_0776.jpg And a test in the dark. :mrgreen: |
Tonneau Cover I decided I wanted to store my light circuit and power source in the bed of the truck so as to keep it from view. I realized pretty quickly I needed a cover for said bed so I started brainstorming ways to fix that. My wife and I were browsing the Styrene selection at the LHS and she had the idea to use scale diamond plate as a cover, so I bought some and ran with that idea. http://i1074.photobucket.com/albums/...r/IMG_0757.jpg I devised a hinge mechanism to make it open and close. After measuring I added a little extra material onto each of the three bed sides. I used some heat to soften the styrene and bend it into shape to make some sides to slip over the bed sides. I used a bit of 24AWG solid core wire as the hingepin and some styrene tube as the other half of the hinge. Here you see I painted it using chrome rattle can paint(after using primer). http://i1074.photobucket.com/albums/...r/IMG_0747.jpg Here you can see how it fits when being mocked up. http://i1074.photobucket.com/albums/...r/IMG_0759.jpg I used some amazing goop to secure the wire to the cover after slipping it through the styrene tube(which moves freely at this point). I used some thin(.030") styrene sheet to make a back on my cover. The diamond plate was pretty thin so I needed to strengthen it. http://i1074.photobucket.com/albums/...r/IMG_0761.jpg Here you can see how I mounted it. I glued the outer styrene tube to the base of the window using amazing goop(as you can tell I love this stuff for heavy use bonds). http://i1074.photobucket.com/albums/...r/IMG_0763.jpg Here is a picture from the inside to see the workings of my hinge. |
Wheels and Tires My wheels and tires finally made it here and I wasted no time in getting them on the crawler and testing em out "thumbsup". http://i1074.photobucket.com/albums/...r/IMG_0758.jpg I took the foams out and used some solder to add weight. After assembly each wheel is about 32 grams. Not quite as much as some others I have seen but it's much better than stock(at 10 grams). I love that these are beadlocks and I don't have to mess with glue. Also, these tires are wicked looking. http://i1074.photobucket.com/albums/...r/IMG_0764.jpg All mounted up. I know it seems a little tall but I actually don't have any tire rub with this setup. If you noticed the back is sitting a little low, this is because the car's battery is in the bed(i fixed that after the fact) and the springs still weren't up to snuff. http://i1074.photobucket.com/albums/...r/IMG_0766.jpg Shot showing articulation with the new suspension and tires and wheels. http://i1074.photobucket.com/albums/...r/IMG_0767.jpg I took another shot from the side. http://i1074.photobucket.com/albums/...r/IMG_0769.jpg As I said the battery was too heavy, so I made a little removable bracket for the rear axle(this way it wont be there when I am displaying the truck). In this spot it crawls much better. Overall it crawls much better than stock now and I haven't even beefed up the drivetrain. http://i1074.photobucket.com/albums/...r/IMG_0768.jpg I had to put at least one pic of it on the rocks. --I will probably update again later with more final assembled pics(probably with lights on) and possibly some video. I will also take a few pics of my little "rock garden" where I have been crawling. Enjoy the updates :)!! |
Video Still hard at work this morning... Got a video of it running. <iframe src="http://www.youtube.com/embed/i5fNeOGJbaM" allowfullscreen="" frameborder="0" height="315" width="560"></iframe> |
Re: New to Micros/Scalers First Project Trail Trekker Hummer Build Looks good, but damn it's tall. Have you tried springless yet? My most capable rig low rides and I'll never look back. |
Re: *Updated 2-25-12* New to Micros/Scalers First Project Trail Trekker Hummer Build Man, Paint & detail are really good!! Nice work- H1's rule!! |
Droop Setup & Rock Course So as suggested I have taken the springs out. I left the little spacers on the shock shafts on there for now because I wasn't sure about removing them and if I cut them off I wont be able to put them back on. I have to agree though that it does drive great now, I only wish I had a better servo and motor(guess I won't be done spending money on this thing just yet). On to the pics... http://i1074.photobucket.com/albums/...r/IMG_0781.jpg Here is how it sits now that I removed the springs. I had to move the battery back inside it since the truck bed was hitting it with the springs removed. --A couple of pics of it on the rocks. http://i1074.photobucket.com/albums/...r/IMG_0782.jpg From the front. http://i1074.photobucket.com/albums/...r/IMG_0783.jpg From the rear. --As a bonus I did promise some pics of the "Rock Garden," so here they are. http://i1074.photobucket.com/albums/...r/IMG_0784.jpg http://i1074.photobucket.com/albums/...r/IMG_0785.jpg I plan on extending it a bit more, but I ran out of rocks. You would be surprised how hard they are to come by down here in Houston. I have some family gathering me a ton of granite from the Texas hill country(lots of granite) this weekend so hopefully I can get those from them soon. --As always enjoy "thumbsup". --Also would removing those little shock spacers have any detrimental effect or would it probably be the best thing to do in the droop setup(I am still a scaler noob). |
Re: Droop Setup & Rock Course Quote:
Truck looks much better! Stability is a good thing. "thumbsup" To remove the shock spacers requires complete shock dis-assembly. You have to remove the shock shaft from the body to get those buggers off. You can cut them off, they really serve no purpose other than limiting travel. |
