Great upgrade and job Pete.👍
Many thanks indeed. Best wishes to you 😁👍
Another great video Pete , I really need to try out the hot racing set , as you know I went down the Kimbourgh route but this does seem like a cracking solution.
Ahhhh metal pivot balls yeah there definitely the best way to go funny thing is I’ve used my Krayton 4s v2.5 about 10 times now and noticed a fair amount of slop .
On all my 3s and 4s I’ve done that and had no issues but for some reason forgot to do so with my K4 .
Right were is my bank card 💳 lol
Stay awesome buddy

Hiya Chris. Oh yeah the Kimbrough servo saver is certainly cheaper but what put me off is that you are tapping into plastic so I wonder if that will work loose after a while? Obviously you've had no problems so far. Yeah the plastic pivot balls seem to wear out really quickly and the metal ones do last a lot longer. They are quite a bit cheaper than they used to be so get it sorted mate! Cheers for your great support as ever. Best wishes 😁👍
Great detail Pete, very helpful. Liked the edit too, worked really well 👍🏻
Hiya Damian. Yeah I've covered this stuff before but these Arrma how to videos seem quite popular so thought I'd do another. Cheers for watching mate. Best wishes 😁👍
Great Vid, Thankjyou - Living in Australia and looking to buy same model so these upgrade videos and advice are exactly what i need. Keep up the good work.
@@jasonhoward3307 many thanks for your kind feedback. I bet it's a bit warmer over there than it is here (slightly above freezing 🥶) Thanks again 😁
Very nice! I'm waiting for a gpm servo saver to arrive that can be fixed on the servo without that plastic adapter, I hope it's good
Me too
Oh right I've not tried that one. Hope it's a good upgrade. It's hard to know how strong the spring is until you get it but hopefully it's firmer than the standard one. Many thanks for your great feedback 😁👍
@@PeteWylieRC Has anyone actually managed to take apart their hot racing/gpm servo saver? I want to replace my spring with a harder kimbourgh one, but the servo saver does not seem to want to come apart 😅
@@vxndxtta_41 Somebody in the comments on another video was saying that they had put the Kimbrough spring into the stock Arrma servo saver but not sure how to get the Hot Racing one apart 🤔
@@PeteWylieRC What was the name of that video? I honestly do not care what material my servo saver is made of, I just want it to not strip out adapters and still be tough.
That cat lol...very intune to what it is you're so into. You pulled it out it came over " let me inspect this yep thats it, you got it human.."
Haha, yeah he's everso helpful for quality inspections 🤣 Many thanks for your great feedback. Best wishes 😁👍👍
Great video, Pete. These Arrma RC's are really starting to grow on me, it seems like a no-brainer to pick one up and bash it around. The wife has a Typhon buggy which I installed a Spektrum BL system in, and it's a beast! Very tough, very fast, very fun and well priced! Cheers dude!
Hiya Fil. Yeah I think it's good to have some RC's that you can crash without worrying too much and these Arrma's fit the bill perfectly. I can leave most of the Tamiya's for the nice summer time runs on the grass. Many thanks indeed for watching mate. Best wishes to you 😁👍👍
Hi Pete, I was astonished to see how much play there was in the steering of this rig - more slop than a TT02!!! Nicely explained and demonstrated mate, and a bonus tip at the end! At least these rigs look well thought out and easy to work on. I do like the look of this Mojave, very nice. Happy Easter again Pete! 🤗👌👍
Hiya mate. Yeah it's surprising how quickly those plastic pivot balls wear out on these. I don't think that driving in the sand helped much. I think you always end up with slop in the steering and suspension if you have a car that is well used. Yeah I do like the way that the whole servo, esc and receiver box comes out as one piece so you can get to the servo horn. It's a nice scale looking truck this as they've put quite a few details on the body and also it's got an internal roll cage that plugs into the chassis. Cheers for watching and your great feedback as ever. Happy Easter to you too 😁🐣
@@PeteWylieRC Oh yes I agree Pete, when your balls have had as much wear and tear as yours have, it's always going to get a bit sloppy down there! 🤣🤣👍👍
@@MarkBryanRC Well yes I do give them a bit of a hard time 🤣
appreciate the video! Would love to see more upgrade videos like this! I own a Mojave 4s and have done bumper/skid plate upgrade but am coming up on 8th or 9th run and gonna need deep clean mine. So I have been doing research on disassembly videos and such. Thanks again, much appreciated sir! 😄
Many thanks for your kind feedback. I've done a fair few videos about taking the 3s cars apart and the 4s cars are mainly the same. What's the bumper upgrade you did? I'm interested if there is something to protect the front of the Mojave better. Thanks again for watching 😁👍
@@PeteWylieRC Link didn't work. Part#ARA4404T1, Brand: Raidenracing. Its on Amazon.
@@ericflynn1515 ah that's great info thanks 👍
Always a good one to do work on. There are lots of upgrades out there. They DO make a big difference as well. Nice work bud. AND nice run out there
Hiya Nick. Yeah these are fairly easy to work on and seems to be well supported with third party spares. Yeah this definitely made quite a difference as the steering had become a bit vague. Many thanks indeed for watching and your comments. Best wishes to you and yours 😁👍
My Hot Racing servo saver link pivot ball came out on my Kraton 4s v2.5 as well! Unfortunately I threw it away before watching this video! I didn’t realize there was a difference between sides! Luckily I ordered a new aluminum steering bell crank linkage set and it came with the matching link! I still put a washer on it just in case it does the same thing! Great video! Thanks from Ohio!
Ah that's interesting so it might be a flaw in that part. I think it is better to have a washer on there to make sure it can't slip over the screw. What's the new one you got? Hopefully that's working well. Many thanks for your great feedback. Very much appreciated 😁👍
Looks like a much needed upgrade, nicely presented as always, Pete! Funny, I was just looking at one of those Ecoboost servos yesterday...
Hi there. Yeah I've put these Ecoboost servos in all my Arrma's now and all still working. They are really quick and responsive. Cheers for watching and your kind feedback. Best wishes 😁👍👍
Hi Pete, I hope that you’ve had a nice Easter weekend. A nice upgrade to the amazing Arrma, I guess all the Arrma’s eventually will suffer the same wear, as I would have thought that they all use a similar setup. So a nice video to show how to upgrade most Arrma’s, the metal ball links are a nice upgrade too. Just love your Arrma how to’s 😊😊best wishes to you and the family 😊🤔😎
Hiya John. Hope you've been having a lovely Easter break too. All good here thanks. Yeah these Arrma 3s and 4s trucks are really good but a few bits need sorting to make them better. I think that the pivot balls wear out even quicker running this on sand which I have been doing. Yes your Mega version will be the same and the pivot balls are less than a tenner so recommend. Cheers for your great feedback as ever and best wishes to you and yours 😁👍
good upgrade . definitely helped out 👍 such a nice truck 👍
Hiya Dom. Yeah this is a really nice bit of kit. I think you'd like it over at Sandy Bottom. Cheers for watching mate. Best wishes 😁👍
My gosh... More slop there than in Barbara's beaver!! 😂
That's nearly as bad as my monster beetle mate!
Worn balls and slop are never a good look, especially when you are driving something of that power.
But, after seeing these rigs in action it's easy to see how much wear the plastics will get.
Great upgrades there mate, I bet that has made a lot of difference to the performance!
I've never owned or worked on an Arrma, but they look well engineered and easy to maintain.
I bet Holmsley is as sloppy as those plastic balls at the moment after all this rain mate?!!
Hope you had a great Easter fella.
😊 👍 👍 👍
Omg Barbara's beaver 🦫🤣😂pmsl 🤣 Anyway yes my worn balls were certainly an issue. These are great trucks and very high performance but need a little bit of sorting out. Oh yeah the video of this driving through the mud was up at Holmsley. It is rather soggy in the forest at the mo. Thanks for your great comments as ever mate. Best wishes to you 😁👍👍
Verry helpful. Greetings from germany.
@@Frumsl84 Many thanks for your kind feedback. Best wishes from the UK 😁
Very helpful. Thanks a lot!
@@Batz-Bentzer thanks for your kind feedback 😁
Great upgrade mate 👌
Hi there. Yeah it's certainly made this drive better. Many thanks indeed for watching and your comments 😁👍👍
Boy it did have quite a bit of slop in it from the worn out balls. Nice upgrades and it should hold up a good bit longer now!
Hiya Addam. Yeah it's surprising how quick those plastic pivots wear out. These upgrades have certainly improved how this drives. Many thanks for watching mate. Best wishes 😁👍
Very nice servo🤩👌💪
Hi there. Yeah it's a great upgrade for the money. Many thanks for watching 😁👍👍
V helpful, thanks!
Many thanks for your kind feedback 😁👍👍
Hi friend, I love your videos!!
What is the purpose of the rubber piece you put on the servo rotor? Do you understand me?
Thanks again
Hi there. I'm not sure which bit you mean. Where in the video is it? Thanks 👍
Good stuff mate hopefully meet up soon for a bash
Cheers mate and yes I hope so. Glad you sold me this one. It's great out of the box but even better with a few little mods :-)
Great video, would you mind sharing links to the product’s please.
Hi there. Thanks for watching and your kind feedback. The products are in the description but I don't tend to put links because UA-cam is worldwide and so it's better if you google it and decide where to source it from. Thanks again.
I did see that. I will google it!
Nice tips, thanks man.
My kraton 4s understeer is the worst, i hate it.
Just bought the HR servo saver too, i didn’t received it yet.
Do you still got good result with it? I heard the string is still a bit weak on this one.
Yeah the steering really lets these down. The 3s cars seem fine with the stock servo saver but these 4s cars are a bit heavier. I found that the HR servo saver was strong enough. Not sure if there is a better one that will fit easily. There is the Kimbrough one which I did but but managed to break while trying to make it the right shape as it needs trimming. I am going to try another one of those as people have had good results. Many thanks for watching and your comments 👍👍
my mojave 4s servo died today after i updated the transmitter & receiver to the flysky with gyro. i never liked the weak steering & always turned to the left a lot slower that to the right.
Yeah the electronics don't last as long as they should sometimes. I haven't had any issues with the JX Ecoboost servos so far. Thanks for watching and your feedback 😁👍👍
can you do video how to do fron and rear diff stepby step thanks
Hi there. I may do a video of that for the 4s cars eventually but meantime I did include that in a video for the 3s cars which are mostly the same. One difference though is that the drive shafts on the 4s cars are attached to the diff with a bar held in with a clip rather than the screw in the centre like the 3s cars - ua-cam.com/video/ftYV8S1Xg-s/v-deo.html
Does the hot racing servo saver mount right up to the stock servo ? And will it improve my steering i have the 4s v2.5 arrma kraton
Yeah there are adaptors for the different servo spline sizes. Also have a look at the video I did about the Kimbrough servo saver. You need to modify it a bit to fit these but it is cheaper 👍👍
I gonna try fit the 6s servo horn so wont need servo saver not sure it fits we shall see
@@owen8538 The thing is if there is no servo saver you will probably strip the gears in your servo. It needs a bit of protection even if it's high torque
Did the 6s kit fit and work no worries😀
Is this compatible with traxxas t maxx?
@@JaimeBGonzalez not sure but best to get one that is specifically designed for your car 👍
@@PeteWylieRC any ideas ?
@@JaimeBGonzalez I haven't got this truck but looking at the parts online I think that this Hot Racing one will work but you don't need to use the arm that comes with it. Might be good to confirm this with someone that owns the same truck but it does look very similar 👍
is 23t o 25t?
thanks
Hi. The Spektrum servo is 23t and the new JX servo is 25t. The servo saver comes with adaptors for either. Thanks for watching 😁👍
@PeteWylieRC Ok thanks, so if I'm going to change the servo like yours, it's better to buy the 25t one, right?
Wid it fit big rock v3
Hi there. Yeah the 3s cars are the same. Thanks for watching 😁👍
Can u link it please dude
