Popular Post babylon Posted May 30, 2020 Popular Post Share Posted May 30, 2020 I try not to let the parts support sway me to much on my decision making when it comes to kits, I think the only time it matters is when your talking about a particular part of a car. Let me explain, Example here is gonna be the HobbyKing Berserker, I know some here have had it and got shot, I love it, I still have a new one in it's box, Now the the front lower and upper arms are pretty unique, So could be a problem, But I have a few extra sets so I'm covered, But everything else. I was out the other day running hard over a nice dirt track with lots of undulating dips, The sort of stuff that sorts the mechanical men from the boys, Well two Berserker diffs failed the test, I did expect it, But was prepared, So home we go, Now I already new that HPI diff gear set fitted spot on and I had a new set of these, But I needed a set for the rear, Having an old Kyosho MP7 sitting in a box in bits and knowing the diff was the same size, I took it apart and whipped out the gears, Now they had a different tooth count, Other than that, Perfect fit. I then notice that I had bent the front inside hingpin holder, It is alloy, But too many cut out making it weak, So looking at the MP7 chassis I see the the holders are still on, So lets see This is the front inside Berserker Holder This is the MP7 inside holder This is the Berserker holder on top of the MP7 holder This is the front Berserker holder This is the MP7 front holder This is the MP7 on top of the Berserker What was more amazing is that the MP7 gearbox had 2 plastic dimples to help position the inside holder which had 2 holes near the bottom Turned out the Berserker gearbox had the exact same dimples So MP7 hingpin holders fitted with no modifications What I'm trying to say is that it shows how many of these companies have have copied each other over the years, And we are not talking clones, How is it that other than tooth count you can swap the whole diff or just internals from a HPI Trophy to a Kyosho MP7, Is that coincidence, So much stuff is interchangeable these days. It just go's to show that hope is never lost when that part number returns zero results in google. 4 Quote Link to comment Share on other sites More sharing options...
Nick Posted May 30, 2020 Share Posted May 30, 2020 Nice find! Knowledge is power. I think though this is mostly a case of Chinese brand copys American brand. HPI, Losi, Kyosho etc do the hardwork. There's so many rebrand models out there now. Quote Link to comment Share on other sites More sharing options...
Jumper Posted May 30, 2020 Share Posted May 30, 2020 even if they are all designed separately they can often come to the same conclusion, because physics are the same for all the companies, so the best suspension geometry and layouts will apply not matter which company make it. for example if you have hinge pins made from steel, the strength to weight ratio will mean the best thickness is xmm and the best length is x mm. its unlikely that someone is going to order 3.15678mm shafts and they are probably just going to round it to 3mm, hence lots of things end up being very close or even the same size. 2 Quote Link to comment Share on other sites More sharing options...

babylon Posted May 30, 2020 Author Share Posted May 30, 2020 I needed one of them plastic Hingpin retainer jobies for my Thunder Tiger S3, Happen to have an Sworkz s350 here, Guess what, S350 retainers were exactly, And I mean exactly the same size as the S3.

Ninetiesbeard Posted May 30, 2020 Share Posted May 30, 2020 Hpi savage diff cases are a direct fit to hpi/hotbodies trophy and lightning diffs. I think most 1/8th stuff is the same, why reinvent the wheel i guess Quote Link to comment Share on other sites More sharing options...
Kpowell911 Posted May 30, 2020 Share Posted May 30, 2020 So because you happened to have an old Kyosho lying around its ok to not factor in how easy/hard it is to obtain spares when making a significantly expensive purchase, as you can just bodge something else on? Got it! Quote Link to comment Share on other sites More sharing options...

Got it! My God, What is your problem, No, I don't factor in spares, Cos I have never had trouble getting them, I had trouble 30 years ago when the internet never existed, When getting any part for anything was a week long exercise and a cheque in the post, But now it's easy, You might get shivers down your spine when your part number search comes back blank, But I've been doing this long enough to know what I can and can't use in it's place, And happy to use a little bit of ingenuity, So it don't bother me. I'll finish by say at least I'm bringing something constructive to the Forum, Some months back someone asked about a Hong Nor diff he couldn't get , I put up pictures and measurements showing he could use a Berserker or Kyosho diff as a straight swap, Hong Nor CRT universal drive shafts will fit a HPI savage, the front hingpin holders from the Berserker and the Kyosho I also now know fit the front of a CRT, So probably work with the buggy as well, And the rear Kyosho hingpin holders also fit the berserker. Maybe none of this is of interest to you, But some here have these trucks or buggy's, Some won't be put off a good product just because they can't get a screw in a packet with the part number and logo printed on it, Some people are happy to try an arm or drive shaft from another model rather than sit in the corner crying and moaning they can't get spoon fed parts, Like I said, At least I'm bringing something constructive to the forum, What have you done lately.

Kukynas Posted May 31, 2020 Share Posted May 31, 2020 It’s not only that, I think it’s no different to any other business like car industry or electronics, many clients are ok to use common parts if supplier/producer suggest it to use them to reduce the cost of tooling, good example is diff, you can find exactly the same diff in many rc cars, some might decide to use better material but design is the same so tooling cost is reduced and parts between brands are interchangeable Quote Link to comment Share on other sites More sharing options...

I also understand that it's not that easy for someone that's new to the game, And as I said at the very start 22 hours ago, babylon said: I try not to let the parts support sway me to much But why rule out a certain kit because a diff or arm search comes back empty, When in reality, It doesn't. A lot here have swapped parts, If we passed this stuff on more often, Before long we would all have petty good combined knowledge of what fits what, Witch can help to get yourself and others out of trouble, Or not sway you from buying that kit on sale because the model has been discontinued. But it appears that certain ones who have been doing this for some time and should know better, Still need to be spoon fed parts.

Relativenewbyseb Posted May 31, 2020 Share Posted May 31, 2020 I guess for a lot it also can bring back more of the fun of tinkering and just seeing what will fit with the means you have, refreshing that it's not necessarily just bodging [emoji16]Experienced this recently, trying to find hpi parts for an e firestorm and trophy buggy are becoming harder with lots having the trophy diff internals on 'back order' etcLuckily managed to find them however old style e firestorm spur gears has always been fun and they do like to break... the last 3 I had used were ecx spurs I believe from a ruckus that just required the corresponding slipper pads to work fineThis time however I struggled to even get those very easily/cheaply so looked around and found Helion spurs with a very similar internal diameter and actually a few more different teeth counts. So got hold of them for only 2.25 a piece and the embossing for slipper pad location is identical to the old hpi spurs, all that was required was taking the internal diameter up very slightly and they fit perfectly [emoji108]Sent from my VOG-L09 using Tapatalk 1 Quote Link to comment Share on other sites More sharing options...
Nick Posted May 31, 2020 Share Posted May 31, 2020 I remember when I had the RC8T getting any parts in the UK was a nightmare but it was also mostly imperial so finding compatible bits off anything was a struggle! Quote Link to comment Share on other sites More sharing options...

Although I'm hoping that with the hardened diffs all round now that won't be an issue [emoji16]I mean I thought it had them already until I saw the powder filled diff case, lasted very well considering Sent from my VOG-L09 using Tapatalk Quote Link to comment Share on other sites More sharing options...

Tug Posted May 31, 2020 Share Posted May 31, 2020 I'm sure those were the gears that failed continuously in my Kyosho Scorpion XXL VE, but Ttypedan came to the rescue by figuring out how to fit a CEN Colossus diff fit, top fella! The car doesn't get run much, but the diff ain't failed yet! Quote Link to comment Share on other sites More sharing options...
