Fix & Run - Redcat Earthquake 3.5 Big Block .21 Nitro Truck (PART 2)

[@talonvaughn6175]

In the last month I've bought an X Maxx and a T Maxx 3.3, I'm not going to get into details, but I think for the price of those trucks they should at lease be broken in before multiple things go wrong with them. This video sealed the deal for me with buying a RedCat. Subbed.

[@hybrid32494]

hey my dude! I ran this redcat today actually. I'm still having some weird fuel issue, but I got mine used, I cannot blame redcat for that. Price wise this brand is great, plus their customer support is very good too. Welcome to the NitroGang! I agree the new Traxxas models are just crazy overpriced.

[@STEVOD313]

Ur sound when u play music sounds like the mix tapes I use to make when I was a kid n use to hold my recorder next to the speaker when a good song came on the radio LOL

[@hybrid32494]

ahahah, I used to love making those mix tapes, those were the days, So Easy. Never needed 4G or Wifi, ahaha.

[@eddyrejserbil4229]

Nothing like a fresh, Clean and powerful nitro!

[@hybrid32494]

thats right!! You know it!!! Im currently wwainting on a new fuel tank for this, then I will test the top speed.

[@Clickbaiters]

Sweet! I wanna see a real bash session now! In terms of the tune: -Your HSN needed to be backed off at approx 2hrs to rid of that throttle pull lean bog. Also, it could have been that you were running on fumes so naturally, you'll lean bog under load towards the bottom of the tank. Only you can answer that since none of us were there. -LSN: Don't worry about what online forum "tune experts" have to say. A good LSN starting point on any engine is flush with the carb housing and tune from there. Your ear, throttle feel and in some cases, smoke level will tell you if the engine is happy with your LSN setting. Anyone can tell you "hey, I have that engine and two full turns in on the LSN is perfect." Well, what works for them won't work for you. What if the person advising lives in Denver while you're in NY? Always tune by ear and throttle feel! All else is a guide at best.

[@Meyers2strokeRcgarage]

Awesome video!!! Looked like to me that the previous owner had no idea what they were doing. They were all cheap simple fixes so you basically got that thing cheap as crap that’s awesome!!!

[@hybrid32494]

exactly, I was surprised. That stainless steel screw was the whole issue with the steering. What i like about this as I say in many vids is that it's only got 2 diffs, instead of 3, like most buggies and truggies. Thats why this can actually wheelie.

[@HD-84T]

Got me a used redcat racing earthquake... For the price it's pretty damn good. Got me back into nitro RCs again saving up to get me a t maxx soon !!!!!

[@hybrid32494]

whats up my dude! I'm glad you're liking this truck, it gets alot of negative feedback which is mostly just from user error because many beginners buy them, you know. Otherwise if you're a carefull nitro driver like I am, these are solid trucks with great features. you def need a T-maxx 3.3 though too.

Awesome fix brother,love the look and sound of it,Redcat RCs are pretty awesome,thanks for the update.

[@hybrid32494]

thanks for watching my dude. My thing is I don't have ridiculous expectations for RCs under the 300 dollar price range. This is still the biggest, fastest, big-block nitro truck you can get for under 300 bucks new. It's not as great as the revo but better than the overpriced T-maxx.

Awesome!!! I used to own one of those but had to sell it but I’m going to buy another one because they are a fast awesome brasher.

[@hybrid32494]

hey dude!!! thanks for watching. I agree, for the money this is the best feature packed model you can get. Redcat makes a lot of other nitros, but this one is pretty unique, and not like the cheaper .18 models they sell.

[@superowen21]

Glad to see yours shifts, my tornado s30 has 2 gears but it doesn’t shift and we’ve done the adjustments. Does it need a new and more reliable transmission?

[@hybrid32494]

hey buddy!! Chances are you need to screw in the adjustment set screws in the trans all the way in first, then back them out. Sometimes this works. Sometimes the spring inside which is under tension is jammed or just broken, and you might need to take the 2-speed trans unit apart. It's not really that hard, just be careful of where things go and take pictures.

[@superowen21]

hybrid32494 okay thanks you I’ll try. If it doesn’t work I’ll get a fast single speed trans for it or get a new 2 speed all together

[@hybrid32494]

good luck man!! let me know. I think your best bet would be to just get a 2-speed from ebay. They are not that pricey for a complete trans.

[@thisguygaming1144]

I have a problem with mine where it won’t go into second gear please help.

[@hybrid32494]

hey buddy! What's up. Can you tell me if you tried to adjust your 2-speed shifting point? that's the only way to get it to shift earlier or later. BTW, you gotta first be sure that your engine is'nt too rich, and it's hitting the higher RPM range and not bogging down. Without the higher RPM the 2-speed clutch won't engage unless you adjust it to engage extremely early.

[@thisguygaming1144]

I have adjusted the shifting I will try to tune it. Thank you. Stay safe.

Hi there. What is the factory setting of the carb? How much turn out, on low and hi speed needle. Tnclx in advande

[@hybrid32494]

hey buddy! I gotta say, the tuning of this carb is highly unpredictable because it's such a terrible design. I just googled it and it says the HSN is flush with the top and the LSN is flush with the carb body. I highly recommend replacing the carb if possible, otherwise just run it as long as it runs without overheating.

[@ivandrrccoffie7734]

[@xboxice2005]

I had one,but it was brushless 😊

[@ElocFSU]

Hey Nitro Guru. I also bought a Earthquake 3.5 off of eBay back in 2018. Got a great deal, looked to be in top top shape. Shame on me but I quickly looked at it when it was delivered but I never even checked it out in detail or tried to start it until just recently. Something seemed funny with it so I disassembled the engine. Sure enough, the housing of the one way bearing was sheared in two! I ordered a new one but I'm not confident that the engine had been assembled correctly. Question - do you know of an exploded view or schematic for a SH .21 engine? I've searched everywhere but can't find. I want to make sure that I reassemble correctly after I received the new OWB. This one has the electric start kit, no pullstart, and I'm not sure of the orientation of the backplate or of the electric start unit. Thanks!

[@hybrid32494]

hey my dude!! Nitro Guru is here!! LOL. It sounds like your are saying your pull start itself was bad, right? Because the only thing the one way bearing is sits in is the plastic pull start, all the other parts are the backplate which is metal. I just looked at my own model to check, and this engine is exactly the same in terms of assembly as any nitro motor, meaning the pull start or any rotostart will only go in one direction (you will notice the backplate is a particular shape with a side sticking out on top - this is how you will align your new assembly). You need to first check if the engine spins over by moving the flywheel with your fingers before you do anything, also would be useful to remove the cooling head and inspect if it actually moves and add some oil (wd-40 is fine, 3 in 1 is fine, aftersun oil is ideal). Let me know. The exploded parts won't help you here, if it moves freely then you should just leave it alone.

[@hybrid32494]

for your reference here is a manual I found for this engine. www.manualslib.com/manual/970761/Sh-Engines-Sh-21-Xb.html?page=5#manual

[@ElocFSU]

Awesome, thanks, I’ll check out that manual link. This truck didn’t have a pull start. It already had the electric start plate installed when I got it. But the one way bearing was literally broken in half. There’s a metal piece around the bearing that fell apart into 2 pieces when I removed it. The metal was sheared. I had the entire engine taken apart earlier, all internals were clean and moved nicely. All I need to do is replace OWB and put it back together again. Correctly. :)

[@hybrid32494]

great!! long as it all moves, you're solid. Consider this an upgrade, lol. Good luck. Let me know how it work for you later. I need to get mine running again, I have not run it since this video.

[@ElocFSU]

I’ll let you know how it goes. Hopefully can put it back together next weekend. Credit to you for firing me up about it! I watched your video and the Earthquake looked awesome. Gave me the energy to tear mine down to see what was wrong with it. Gotta do what it takes, right?

I watch your channel all the time great stuff! But i have been driving electric rc cars for the past 4 years but have been thinking of trying naitro or gas rc, what would you recommend for a first timer gas RC truck?

[@hybrid32494]

whats up man!! You got a huge choice with nitros, what matters is if you want a big block .21 engine or a small block, .18 or .15. Id say for the price and spec this is a good one to start with and it won't leave you wanting more right away. Ofcourse any traxxas nitro is great too, but a t-maxx will be around 150-200 more. But you will have a nice electric start system for that money.

[@KillaC57-sm9cl]

I bought the earthquake 3.5 and I am having trouble breaking in my engine. I have to open the throttle al the way for it to start. When it does I then throttle it down but it keeps cutting off.

[@hybrid32494]

hey man!! thanks for watching! Can you tell me if your carb settings are correct? Meaning when your carb closes do you see enough of an idle gap there. If not, adjust your idle set screw some. Let me know, this is the first place to start looking.

[@KillaC57-sm9cl]

@@hybrid32494 I set the high and low screw to factory specs and I do not know about the idle gap. Please explain further if you do not mind and have the time too.

[@hybrid32494]

glad to help my dude!! you need to visually look inside the carb (where it opens) and observe if your idle gap is big enough. This is done by pressing full brake and looking to see if there is some gap in the carb opening for air to get through. If it's really small, (like under .4mm) then turn the Idle screw clockwise to increase the gap until the truck no longer turns of when you apply the brakes. Let me know. It should be not more than 1mm at most.

Is there any chance that i could sent me nitro truck of to u so u could have look at it n maybe fix it for me i used it once and have no clue about nitros it starts up then wen u give it gas it cuts off

[@93jake81]

The high speed needle is most likely too rich. Try turning it in until it doesn't stall when you give it gas

[@hybrid32494]

hey man, I would love to work on and fix your nitro, but trust me that shipping alone would be cost prohibitive. I would estimate each way would cost like around 30+ dollars, not wroth it. Chances are you need to lean your high speed needle out by a quarter turn to begin with. That means turn it clockwise to close it some. Try that, and eventually you will notice it will not shut off as much or at all.
