You can see i’m missing a wheel here, because i’m messing with the transmission i’ve just figured this out, so i wanted to share this. This is the first part of this video and really this is what was holding me back. The the engine is the one thing that’s not mounted so far, so i’ve got the fuel tank set up, just like my mini t, actually, the same 3d printed part at the bottom. There um same three hose system, but the difference, of course, is that the the mini v is significantly smaller and i didn’t want to mar the body too much so i’m not going to be able to have the throttle servos stacked. On top of the steering servo. You can actually see this is this: is my receiver that’s an sr215 stripped out of its shell? I just hauled out some of this plastic and slotted it in there and glued it in uh. If it’s fine plugs in fine i’ve got the throttle servo plugged in as well uh flatten out the chassis part to fit the the rest of the engine, so that’s all set. But my next, my next step, the thing i’m waiting on is to figure out where the engine goes and before i can figure out where the engine goes. I need to figure out where the spur gear goes now. The spur gear i’m using here is a traxxas part. Uh. Forgive me, i don’t have the packaging in front of me.
This is a 31 tooth mod 8 gear. I also pick up a 34 tooth that’s traxxas part three, five, six, three, nine uh. I think the other one was five six, three four or something anyways. This is actually a a pinion gear for an e max which they don’t make anymore. So these are getting harder to find, but they’re the fantastic they’re, just the perfect size for many nitro applications and since uh the clutch belt i’m using is hsp it’s mod 8. So boom considered a spur. U so this here here is going on the buggy, and i just wanted to share how i got that on there. So, first and foremost, the the stock uh transmission setup had a pin that went through here and went into a rear plate that the spur gear had on i’ve replaced that with a small tamiya body clip just so it has something to sit on i’ve done. The same thing in my mini t, this is where it differentiates from the mini t, though next i’ve got next i’ve got camera problems, apparently uh anyways. Next i’ve got this little guy. This is actually a caller from a uh 90 millimeter hot racing shock it’s, intended to space the shock off from a shock body. I think it’s for a traxxas vehicle, but i’ve you can see it’s uh. It was anodized blue it’s really hard to focus. This is now uh shaved down into a tapering cone so that this sits perfectly on the shaft and is just a little bigger than the end of the gear.
The gear is again kind of hard to see, but i’ve beveled this out with a one size up drill bit that basically just sits on there and with enough force centers the gear that guy goes right there and to hold it all down. I’Ve got uh. This is kind of a weird it’s, a red cat bushing, to go on the bottom of a redcat volcano steering knuckle with a o ring. I believe that held on a tamiya body kit, part and a washer, so just stack them slip them on the shaft bolt. It down and here’s the gear installed, it’s actually uh, putting pretty well put together there lacking the shock, the engine again i’m still trying to get it to lay down sideways. That 31 tooth gives me just enough clearance between the flywheel and the transmission. Housing should be good, so next step, i guess, is trying to figure out where the engine is supposed to sit and drilling those screws. I expect i will keep this stock uh. This is actually an hsp engine mount that happened to bolt up to this pico engine. I think i’m going to keep that try to drill some holes through here and uh. You know screws up through the bottom of the chassis into the holes that i drill through the side of the mount, with some washers to space it off, because you can see this distance here, uh it’s, probably about i don’t, know two three millimeters um.
That needs to be filled, of course, so that the entrance it’s fine, so i’ll figure that out and i’ll make another segment. Okay. Okay, sorry! I i really need to slow down between these videos, because i just get into the mood and just work. Work work, anyways uh, some progress got the engine mounted uh gear mesh is fantastic thanks for asking uh. If you were paying attention, you noticed the slide was going to move up which makes tuning a real pain in the butt. So you see that slot there that’s uh that’s for the high speed needle. You just see it through that window and then the idle speed is through that hole right there there’s the ice idle speed, so i can tune the car from from beneath um. I got the fuel into the carburetor there that doesn’t kink luckily and then the servo uh 3d printed these little feet and made an l bracket for it. So it’ll mount just like that and uh, hopefully it’ll work we’ll get it hooked up. I guess this is where i’m going to have to call it today, uh i’ve been working on this basically non stop it’s, basically done uh other than the exhaust and i’ll talk about that here in a second but uh yeah this. This has been an interesting trip. Um not super thrilled with how that break is i’ve got the the battery charging here. Speaking of battery, it is a single cell, one, four, five: zero zero, basically double a size, uh lithium 1s battery, so that’ll mount right there behind the engine and it charges through its own dedicated charge port and runs under the engine.
Hopefully that’s, not a problem. Uh power switch interrupting it on the way and soldered into the back of the receiver for power, so just flip that switch power’s on uh it’s charging right now that’s. Why i’m not flipping the switch but uh glow start for the tip of the glow plug uh? The base of the glow plug i had soldered onto a washer under this nut, which has conveniently falled off right before i started. Shooting so i’ll have to re solder that but i’ll have a remote. You know glow plug starting setup. Uh throttle is a Music interesting uh get up here. So basically it’s an l shaped that’s throttle open, throttle closed brake and the brake pushes, instead of pulls the uh fuel line against the clutch, spell uh it’s all fairly effective. Actually, it looks like my charging’s near done so i’m gon na stop the charge unplug it give you an electronics run through so power switch, see the sr215 turn on that orange light up. There left right, of course, it’s all open all closed break and the brake is pretty effective, open, coasting coasting kind of drags. I can add, or remove washers here to change that and break um, so yeah. The big thing for me was that throttle was responsive, opening and uh snapped back closed when asked without applying brake and it does, which is fantastic, um and the body. So here we go this wire, i don’t know where i’m gon na i’m gon na put the dummy glow plug, but it’s gon na be somewhere i’m just gon na tuck it for now also not 100 sure on how i’m going to hold the back of the Body down but, like i said i’m, pretty much done for today, so just showing you, the progress i’ve made, unfortunately had to cut out most of that side enough for engine cooling.
Hopefully these holes are supposed to help with that. I think in the exhaust manifold comes up and goes around now when it comes to the exhaust. The manifold is going to mount right like so and uh. I plan on connecting and disconnecting the manifold every single time, because this silicone pipe is stout anyways. This is a turnigy, mostly i guess, uh nylon or whatever. You know, plasticky thing that they make the suspension pieces out, but they used it on their buggy. So i guess it’s heat resistant enough and then the exhaust i’m going to mount right. There it’s an hsp metal exhaust so it’ll give it a little a little bit of a snorkel look. I guess until i get that connected, but uh yeah. This is this is where i’m. At so far, i think it’s it’s gone pretty well and i’m awfully close to getting it started. Uh. I just wish i had more hours in the day, anyways uh there’s, the mini b engine lays down and all the electronics fit so uh. Hopefully, next one you see, will it be running uh thanks for watching hit the subscribe hit? The like you know all that normal youtuber uh lets me know that what i’m doing is appreciated by somebody, maybe i’ll, keep doing it have a good day. Guys, hey just realized, i totally didn’t even describe how i mounted the engine. Uh there’s no mount back here, that’s. Why? I can put a battery here now, because the engine uh is mounted with those screws that go through the exhaust.
They go all the way through the bottom of the engine into the bottom of the chassis they’re like 40 millimeter long and three screws. I had to force them through to make the threads. You can see them right. There uh the one closest to the camera here towards the rear of the engine, is close enough because it balances on the flat part of the pull start and the head on the bottom. So the rear one is fine without a spacer, but the one further in uh you can’t see it there’s no way, uh there’s another. You know this one all the way down. In there uh on the bottom of the engine. I actually used a traxxas. I think it was a 4×4 slash shock, uh spacer, slash ball joint happened to be the exact length i needed, so i just used it as a really big spacer or washer and stack that on there. So these two bolts are holding it down and you know this keeps it from wobbling around and it’s, not budging anyways. Hopefully, next time i see you guys, i’ll have the exhaust figured out and it’ll be running so stay tuned.
