Dude, I know this vid is quite old now but probably the best informative clip I've watched. I was having a nightmare with my 1st 5th scale not tuning. Which was more to do with me not knowing what I was doing properly, until I watched this vid and realised the LOW NEEDLE was LEAN... WOW who knew... well obviously not me at the time.. great clip thanks

You're very welcome! This is the reason i put these vids up! Thanks for the kind words!

Hi that video was really helpful, I’ve just bought an Fg marder sold to me as a none running car but a new spark plug got it running and after watching your video I’ve got it running really nice , so thanks very much from the North East of England, Stay safe and many thanks mate ...

Thank you so much for sharing this useful information! Now my Redcat Rampage MT runs like a dream!

I'm so glad you made these videos ! Your a gentleman ! Thanks for the reply and tips they are really valuable . I am going to make a vid of my spider . Thankyou so much . From Belfast northern Ireland ! Cheers Rob

Hi mate thanks for the video it was top notch I just got my first 1/5 scale it is a smartech spider and I got it 2 days ago it was running like a dog and would only drive on half choke but after watching this vid I have my spider spinning the wheels and lifting on full throttle I just tuned it as per your vid 1 hour ago I'm running twin boost bottles with a fastrax exhaust and it's a monster now thankyou so much !

Been working on my tuning skills your video helps makes sense thanks

My baja was sluggish saw this video,now she's running sweet.....thank you

sure did help me got a better understanding of how carbs work on these things , have a look at my 5b twininline vid ,lol i say it cut out on the end , but later on i sorted it out its all good now

Great video... some great tips!!!! will be trying this! Thanks.

in my situation i got everything running good, when i lift it off the ground and give it full throttle the rpms get really high and it sounds like it nearly runs 40 mph. but when i put it on the ground and give it full throttle the rpms sound a lot lower and it only runs about 25mph max. prob 20mph honestly. one problem that i noticed is that my breaks are really tight and sometimes engages when i left off throttle but i fixed that but like i said, once i put it on the ground and it has to move its body weight it doesn't wanna run like a bat out of hell. its a 5th scale rampage XB with a 30cc 2 stroke on it. have any tips??

Hi since my 1/5 rc rolled onto roof today . It won't run just bogs down when press throttle. All help appreciated thanks

Cheers Mate! Best of luck to ya!

This looks like my smartech bigfoot. same layout almost. So when i run it it sppudders crazy and bogs right out and shuts off. what would you recomend to do?

I have a KM 30.5cc rbinnovations supercharger and wt990...it seems to be better off idling high than low...any suggestions on where a guy should have the H and L settings on the carb? It just seems like it should have a little more go...,

Thanks for your video! Have you have seen a Rovan 30.5cc idlle great and the slightest touch of the transmitter make it go from the idle to straight fish tailing and sounding like wide open throttle?? Like there is no in-between? My new 5b is doing that and I have a FlySky GT3C radio.....some said junk radio, some said probably bad from factory carb......I tuned the carb like I tune my trimmers and 2-stroke dirtbikes sounds great on stand. Thanks in advance for any info that may help.

I have a king motors 5b with the 30.5 motor and I did just fine till I put a rbinovations super charger on it and now it won't idle or stay running. When I fire it up it winds up pretty high and if I put it on the ground it will drive around by itself and if u give it throttle it Boggs and dies can u help

Thanks for the video. I got a 30cc redcat buggy. It's hell to fire up right now and when I run it, the thing skips. It takes off just fine but like 4 good secs later it starts doing that. Then shuts off

Thats awesome mate! Fantastic, off I go to the garage to smoke myself out ha ha. Thanks for the help liked and subbed (-:

hi i have a 26 cc engine i want to know the numbers of turns for HS and LS screws for better performance Thank you

i have a hpi baja 5b when i try to hit high speed it sounds like it has a flat spot in it could u tell me how to fix that???

When I'm hitting full gas and top speed, it starts to sound like it's not getting enough fuel, like coughs but noting else, i have tried some different settings like u did but still doing the same, it's only top speed it does that. Can it be my Air-filter isn't letting enough air get pass? Everything is original, 28cc 1/5 scale and tops 52km/h

What do you use to charge the battery pack please any photos

@scoobysnacks18 Is the tank vent line clear? If it's plugged the fuel pump in the carb will start to create a vacuum in the tank. Think of a juice box, if you suck the straw it will collapse in the sides of the juice box, as soon as you break the seal the box returns to normal. Your fuel tank can do the same thing if the vent is plugged. When your truck died, did it have fuel in the primer bulb on the carb? Can you get it running again? If so, post a vid of it running. Let me know, PDS..

Make sure the plug is clean and gapped properly, if unsure, replace plug with NGK. If you're still having problems, let me know. What kind of 1/5 did you get? Good Luck, PDS..

hi. my marder suddenly was running rich i beleive but was running ok even though it was smoky on full throttle. then on about quarter throttle it stopped and it aint started since. ive reset everything back to factory settings and put neat gas in the tank just to get it going , but it wont start. plug is good with plenty of spark. its virtually brand new . also cleaned the carb but its dead and wont go. please help

thankyou for the video .

@scoobysnacks18 Before you throw anymore money at that motor, you may want to consider looking for a Zenoah, or at least a Cheng Yeng (CY) these are much better motors, plus you can buy parts to repair them as well as bigger pistons and longer cranks. Keep an eye on Ebay or Craigslist. I see them all the time go for 50 bux. You say the spark looked weak, was it checked with the plug or did you test it with a spark tester? How was it weak, was it orange?

No problem! Send me a link to some vids of it running.

wht i have learned about these big boys is that the spark plugs play an important role in a stable idle heart beat of engine after every round...

hey after you adjust it once do you have to do it often

@scoobysnacks18 No problem. When you get your new switch, it would be a good idea to get a silicone switch cover to go over the switch. That will eliminate any dirt from entering your switch. Davesmotors(dot)com has them for about 3 bux. They have decent prices on motors and accessories as well. Type in LSF in the coupon code box to receive an additional 5% off your order.

settings L1.1/4 H1.1/2?

I'm at a loss I have upgraded my 23cc to a 30.5 cc same carb and settings how do I even begin to get this thing to idle and run

@Poopdogsays

hevymtal1 1.5 on the h.s needle and 1.25 on the l.s needle that should get you close.

I tune my carbs twice per year, once when it gets warm and once when it gets cold.

It will go too lean if you have the HS needle closed, when you close off the needle it stops the flow of fuel. Back the needle out to 1.5 turns aprox and start over. If it still won't run properly pull the car and intake off and make sure you have the gasket on correctly, make sure the holes in the gasket line up with the pulse port, it's easy to put the gasket on backwards.

Hi, I have recently bought a 2nd hand Smartech Bigfoot (i have read all about the low quality of them....) is this a similar car to yours? the layout of everything looks almost identical. I have the 28cc engine, do you know what the stock carb settings are for it? i can't find this info anywhere!!

@Poopdogsays

Matt Stroud the carb settings are about all the same for all these carbs. The problem you'll run into with your carb is that it's a Chinese knockoff of a walbro and is rather low quality and usually won't hold a tune. I would recommend picking up a genuine walbro, it will make your life a whole lot easier. Check out ddm racing most parts are interchangeable with the fg stuff and duratrax firehammer mt.

hi.. i have a himoto baja with 28cc fulie engine. as straight out of the box on my first run i faced some serious issues with acceleration stuff. As i increase the throttle to max, the engine starts to loose its RPM and engine dies. On the other hand with this problem i first give constant low throttle, then slowly like a old locomotive it starts to speed up. please help i need settings to make it run in one go.....not to die.

can I use carb cleaner to my 1/5 sized gasoline rc?

penguinjolt yes I do it all the time, just don't spray it down the throat of the carb while it's running.

@scoobysnacks18 This hobby gets very expensive when you start replacing parts that don't need to be replaced. If the spark looked weak, it's a good bet that the plug is bad. I would start there as it's only 5 bux. I have well over 50 gallons of fuel ran and I'm still on my original coil. As far as the fuel tank, the vent line is the black rubber tube that is zip tied it to the rear shock tower and sometimes the vent gets pinched or fills with dirt. I've heard those SQ motors won't hold a tune.

Hi what is the idle screw stock setting how many turns to open back in the stock setting thanks brother

@Poopdogsays

Start with 1.5 turns out on both low speed and high speed. Adjust low speed first as it affects the high speed setting as well.

Sounds like your fuel cap may not be venting properly, loosen the cap and try it again.

Start with the high speed and low speed carb screws at 1 1/4 turns out. Turn screws in until lightly seated. Then back each one out 1 1/4 turns out. I have better carb tuning videos on my channel, they are in my playlist of largescale tuning vids. Largescale carb tuning pt2 is pretty educational. Lemme know if i can help further.

@Poopdogsays

To start... When engine is cold, close choke and pull recoil until engine "pops" turn off choke, pull till it starts. If engine is warm or hot, leave choke alone, pull pullstart. If you cant get engine to start, try advancing the idle slightly by either giving a little throttle om the controller, or by screwing in the idle screw (big silver screw) If one is new to this hobby, i highly recommend getting the wheels off the ground with a stand, a block of wood, taking off the tires etc. These things can hit 40+mph and its enough to really hurt somebody. Please be safe!

This is 8 years ago but you may be my only hope. I've tried to find videos of tuning those 3 screws and I can't figure out how. I'm new to gas rc and I bout a rovan Baja, I don't think it's tuned. It starts and idles normal but it stalls whenever I hit the throttle. Any help would be appreciated!

@scoobysnacks18 When the kill switch sticks, spray a little WD-40 and that will lube it up and allow it to work properly. The dielectric grease the factory uses attracts dirt. Check GizmoMotors(dot)com they have about the best prices on Zenoah parts. They specialize in boats so most of their stock is water cooled, but they also carry air cooled as well. Can't go wrong wit a 29cc Zenoah and a Jetpro pipe on your truck, makes it a whole nother animal! I have vids of mine (FG MT) on my channel.

i wish the audio was more clear. i get the sluggish about to die but it would be good to hear the difference.

Mine drops down when I start to pull away and then picks back up it also doesn’t give a lot of torque it also doesn’t go over about 15 mph

@40951 Sorry I didn't see you posted a question... "Neat Gas" Help me out here, are you referring to naphtha? That stuff is for Coleman stoves Man, dump that shit and buy a gallon of Gasoline and mix in a 40-50:1 ratio of oil and enjoy your 5thscaleracing. com! I know in certain places Naphtha is common in largescale r/c's, but it's too hard to tune the motor when it runs that shit because of the inconsistencies. Plain ole gasoline will work better for you, brother.

True, but as long as you stick with NGK's you'll have an easier time tuning. Plugs like "Torch" or those damn "E3's" are just shit! NGK's are the only way to go..

Does the motor need to be warmed up before tuning?

@scoobysnacks18 The UK, Shit I thought all Brits had FG's? Hmmm. Just remember when buying parts, Fg parts are MUCH better than the cheap Chinese plastics and most FG parts are interchangeable with the china parts. I had a clone buggy that I converted to FG parts and it's now tough as nails. I know alot of guys in the UK are buying from hobbythek out of Germany because the shipping from the US is too expensive, but it you find a part at DDM he'll ship worldwide for a reasonable post. PDS..

You're welcome! Just as a heads up, the boost bottles do nothing but make your wallet lighter. They do nothing for performance, they just add to the risk of an air leak. Ditch the boost bottles and your motor will live a happy life. Best of luck, PDS...
