RC4WD 4200XL models and nomenclature?
 

Ok, i've been reading all kinds of posts on this and other forums and have some questions. This is my first hydraulic r/c so please be patient on my novice questions if you don't mind. This all may be on me but it seems there are some discrepancies on models and equipment. I supposedly have the version 1.5 but have read some have a 4th servo for a "spillage valve?" Mine only has 3 servo's for the booms and bucket. The rotary knob above the left stick does nothing, neither does switching the 3 pos switch above the right stick off of N. My serial number is on the under carriage not in the operators cabin. The endpoint for the pump motor is set at 30% from factory. My lights have the exterior switch and can't be turned on via TX. Also mine came with spring loaded idler wheels. How does this compare to other newly acquired version 1.5's I was wondering? Also, 30% on the pump motor seems a bit high. What are the rest of you running at? Thanks for any input.

Re: RC4WD 4200XL models and nomenclature?
 

vers. 1.5 is suposed to have 4 valves... the 4th valve is mixed in on the tx so it closes when you use the boom`s and bucket, and open when youre not so the oil can circulate back into the tank.
version 1 only had three valves, that caused some leaking issues with all the pressure on closed valves.

this is the vers. 1.5 valveblock... http://store.rc4wd.com/Hydraulic-Val...15_p_1832.html

i have a diffrent pump motor in mine, but if i remember right i think i heard others say they have it set to 23% or 24%.

Re: RC4WD 4200XL models and nomenclature?
 

That's what I thought. I have the 1.5 block but no forth servo. Yet another failure from rc4wd quality control. I've read some like the control of the 4 servo from the TX and others think it's more to go wrong, any new opinions since it's been out for a while now?
I've got plenty of servo's laying around so I could put one in at anytime if people are really liking the control and may help with leaks, reliability, etc.

Re: RC4WD 4200XL models and nomenclature?
 

Well I was wrong. I do have the version 1.0 3 valve block. I was told I would be receiving the 1.5 and it does have the exterior light swich and bec for the boom lights. Not sure whats going on with this machine, guess it's a version 1.2. Going to see if RC4WD will send me a 1.5 conversion block and servo out of their wallet as I was told I would be getting the 1.5. I've emailed them so guess we'll see what they say about it.

Re: RC4WD 4200XL models and nomenclature?
 

Question did your order directly from Eagle or RC4WD ? I wonder if dealers are converting the first version themselves to 1.5, forgetting things along the way in the process ?

Re: RC4WD 4200XL models and nomenclature?
 

I orderd directly from RC4WD. Interesting that I have 1.5 lighting but 1.0 block. Also gear aux on TX is still set up to turn lights on/off. How long has 1.5 been available? Odd to still be converting and not starting with the 1.5 block unless they have a bunch of 1.0's laying around hence the price drop? Its not a huge deal breaker, hoe will still operate. Just don't like getting jerked around and I'm hoping to get the 1.5 block upgrade on their dime then convert if I want at a later time.

Re: RC4WD 4200XL models and nomenclature?
 

Interesting thought Farmer. You thinking RC4WD may be upgrading 1.0's to 1.5's on their own? Thinking it would of come from CA rather than HK unless the CA address is just a north american office? Either way as long as they agree to send me the 1.5 block upgrade I'm good with it. Just want to get digging!

Re: RC4WD 4200XL models and nomenclature?
 

RC4WD should definitely supply you with correct 1.5 version parts at their cost. Their advertising the 1.5 version for sale on their website and that's what you should be getting when buying one.

Re: RC4WD 4200XL models and nomenclature?
 

Yeah mine came straight from Hong Kong but I ordered directly from Eagle on Aliexpress. It would make sense from the dealers point of view rather then being stuck with old inventory...pass it off as new and improved. Who know's though ?

Re: RC4WD 4200XL models and nomenclature?
 

So according to rc4wd I have the latest version 1.5 and it has a new 3 valve
block system. They also mentioned they are no longer shipping the 1.5 with a 4 valve block but can still be bought separately until they are out of inventory.

Re: RC4WD 4200XL models and nomenclature?
 

Good to know! :cool:

Re: RC4WD 4200XL models and nomenclature?
 

thats weird... not to impressed with rc4wd on this. i looked at their site and from what i can see the only thing they mention about this is that the 1.5 valveblock is now listed as an optional upgrade for the 1.5 excavator?!?!
so is this just the old vers. 1 valveblock they now use? (i would guess so.. since they list 1.5 vers. as an upgrade). thumbs down for rc4wd!!! guess thats where some of the price reduction came from...

Re: RC4WD 4200XL models and nomenclature?
 

Just got an email from rc4wd asking where I heard about 1.5's being shipped with the 4 valve block. I told them I was informed by various owners on various forums and even the manual states to not move the aux switch "N" or it will change default settings of the pump. They are now saying they may upgrade existing 1.5's on a case to case basis. So now let's see what they come back with. If nothing else, all this run around is kinda interesting in just seeing how these jokers are handling this.

Re: RC4WD 4200XL models and nomenclature?
 

What a joke! Sounds like they are trying to scam people by selling the old version but if you are smart enough to figure it out then they will give you the upgrade. LAME! I hope they give you the upgraded parts but it still sucks. You buy the latest version you should get the latest version upon delivery not after weeks of emails and time spent trying to twist their nipples.

Re: RC4WD 4200XL models and nomenclature?
 

Wtf won't be dealing with RC4WD regarding Eagle's products. Guess I was right, they are trying to pass off the first version as the current one! That's hella shady! Going to continue buying directly from Eagle.

Re: RC4WD 4200XL models and nomenclature?
 

Yea, I usually give a strike or 2 to vendors before getting on them but this is really getting out of hand. If it comes to it do u mind if I send them the pic of yours Farmer?

Re: RC4WD 4200XL models and nomenclature?
 

so... first they tell you it has a new 3 valve block system and they are no longer shipping the 1.5 with a 4 valve block, then they ask you where you heard about 1.5's being shipped with the 4 valve block???
i thought rc4wd was a decent company... did they change owners or something? i been saving up to buy the wheel loader from them, sure not gonna happen now!!!

Re: RC4WD 4200XL models and nomenclature?
 

Just wanted to tell you that you're not alone. Dealing with this exact issue as we speak. Mine was shipped about a month ago and now im trying to get it up and running and ran into the three valve vs four valve block issues. Im waiting to hear back but my immediate reply to their 2 day reply definitely slows this down. Good luck........ as it seems we both need it and many more may as well

Re: RC4WD 4200XL models and nomenclature?
 

Glad to hear I'm not alone on this but also discouraged it's happening at a frequency now. Let us know how you fare and I'll keep updating as well. Does yours have spring loaded idlers?

Re: RC4WD 4200XL models and nomenclature?
 

Sure Benny it ain't a problem use the picture, anything to help a member out. Have you contacted Tang about the issues your experiencing with one of their dealers ?

Re: RC4WD 4200XL models and nomenclature?
 

I just received an email stating I received the "updated" valve hydro block. still having issues with slow movement, and the hydro lines loosening up and causing leaks and sucking in air.

Re: RC4WD 4200XL models and nomenclature?
 

Slow movement is likely due to air in the system. Too low oil level in the tank. I don't have a quick, good 'non messy' way of emptying the system for air, but maybe others have? Theoretically the air should come out by running all cylinders in and out enough times, having the tank filled up to proper level at first.
Adding thread locker to the nipples will not hurt. E.g Locktite 542

Re: RC4WD 4200XL models and nomenclature?
 

Sad to hear about the troubles someone experiences with the equipment. I guess one can state that RC4WD is more of a pure 'forwarder' of deals/money between the customer and the fabricator, Eagle. Not a real 'dealer' like one have with full scale machinery, that test runs, upgrades things before delivery, give full service, keep spare parts locally and so on. It's all very cost driven, companies like RC4Wd want's to have minimum stock and personnel, to keep costs down. That naturally influence the degree of service and quality of the delivery. I don't know if there are, or there should be, a professional dealer of the machines in e.g the US, that have good technical knowledge, keep spare parts in stock locally, and really test, check and possible upgrade the machines before delivery. the hobby is quite new..but hopefully things will improve over time and one will have more options than relate to unprofessional 'forwarders' or relate directly to a factory in China, that also keeps number of staff down in order to keep low cost.
If not getting original hydraulics properly up and go, there is always the option to put proper hydraulics in, Premacon, 1000-1200-1400 usd (If so, ask/look for advice at the forum concerning all parts needed in such a upgrade first, if one are not very into hydraulics)

Re: RC4WD 4200XL models and nomenclature?
 

I just emailed Tang to see if there is a "new" 3 block version 1.5 or if RC4WD is being negligent on updating or misinforming customers on what they are selling.

Re: RC4WD 4200XL models and nomenclature?
 

Keep us updated. Curious to see what the deal is...

Re: RC4WD 4200XL models and nomenclature?
 

Ok, so heard back from Tang and he said the newest 1.5's do have an improved 3 valve block and not a 4 valve. He also said to make sure the flow isn't too high and stay at stock or a bit lower on the pump speed which we all know already. Seems a bit suspect until I see a listing to buy a "new" 3 valve block upgrade. If anyone has some pics of their 1.0 3 valve block could you post up please, would like to compare.

Re: RC4WD 4200XL models and nomenclature?
 

Wish they listed a clear description of the parts they updated over the years. Would make things easier to figure which version you have.

Re: RC4WD 4200XL models and nomenclature?
 

No kidding, though I'm sure the 12 year old that "tests" and boxes them up has no idea what they have in front of them, much less the distributor. I'm still not completely sold on this "new" 3 block. I've only heard good things about Tang so I'll take his word...for now!!

Re: RC4WD 4200XL models and nomenclature?
 

I've been following this and correct me if I'm wrong but isn't the new valve block just the same block ?, just three valves instead of 4?

Re: RC4WD 4200XL models and nomenclature?
 

Version 1.0 has a 3 valve block, supposedly 1.5 has a 4 valve block and the "newest" 1.5's have a improved 3 valve block. This is what I've been told by Tang and RC4WD. Not sure what the "improvements" are though.

Re: RC4WD 4200XL models and nomenclature?
 

With the new valve block they should update the 4200 to version 2.0. Would help clear things up for customers wondering if they have the correct parts for their version.

Re: RC4WD 4200XL models and nomenclature?
 

Four valve block on the 1.5 version
"4-way reversing valve, the use of standard servo drive, a total of 4 road, one on the right side all the way to control the oil, under normal circumstances the oil flows back to the fuel tank directly, producing action after valve is closed, the hydraulic oil flow to the high pressure oil. The actual use only three road"

Re: RC4WD 4200XL models and nomenclature?
 

I'm totally confused with this one guys, and I'm sure others are too,,,,

When you say 3 valve block , how many actual servos are connected to the whole block? Three valves and one diverted valve? That's still the 4 valve block. Or are you actually saying the version you are referring to has ONLY three servos and does not have the diverted valve and is using pump with prv to divert flow back to tank?

Re: RC4WD 4200XL models and nomenclature?
 

You got it. 3 valve block=3 servo's an no diverting valve, just usual prv.
4 valve block=4 servo's. 3 for booms and bucket and 4th for diverting valve.

Re: RC4WD 4200XL models and nomenclature?
 

Got ya :).

I'm pretty sure (not positive) but these are shipped from overseas (hk). Rc4wd doesn't see/touch them. At least mine came with overseas post.

Re: RC4WD 4200XL models and nomenclature?
 

Naw Benny's came from Cali and not Honk Kong, RC4WD must of have had it at their warehouse.

Re: RC4WD 4200XL models and nomenclature?
 

Nope, mine came from oversea's. Had to deal with DHL as more import tax was owed before delivery. I had to pay $100 out of pocket, luckily RC4WD reimbursed me via paypal. Just another wonderful experience of this excavator adventure provided by RC4WD. I believe your right, the only thing RC4WD has seen of these are the pics on their website.

Re: RC4WD 4200XL models and nomenclature?
 

My bad I must have miss read your post on the previous page. That's actually pretty good if RC4WD covered the duty fees on your excavator. No one ever payed any of the duty fees I ever had on any of my parcels :( lol That's usually how things go when buying outside of the country you have to pay import tax on it. Also had to pay DHL on delivery.

Re: RC4WD 4200XL models and nomenclature?
 

Oh yea, glad they paid me back. Definitely not a deal breaker, just emailed them and asked why the total cost wasn't included in initial shipping cost.
I know of course taxes change and with the weight it could easily be held up in customs. I gave them a shout for S and giggles and was a bit shocked when my paypal account showed the $$ the next day.
