(skip top paragraph for short version)
I've recently purchased an 1/8 buggy chassis (kyosho inferno mp777 sp1)
Drivetrain was supposed to be included, but it was not here when it arrived, seller ignores my mail.
Now its time to buy a new set of driveshafts/ all round cvd's.
I've seen the price of professional grade drive shafts, 80ish$us for 2/6 parts i need.
I'm considering buying cheaper items, two "easy fixes" are to buy the complete sets (all 6 pieces) from china.
I am unsure of their quality by meerly looking closely at them, they do however mention what they are made from and the production brand.
Also, I'm running a bigger engine in this buggy, its an hpi 2.6

My choice of driveshafts; (links to item page on ebay.ca)

Hardened steel? cvd's

I just want to know if either of these parts are even worth buying, i do have an alternative to both of these, but il be forced to use one 3+ year old front center drive shaft.

thanks in advance.

Ok, personally I would go with the Taiwan set (Taiwanese manufacturing is top notch in a lot of industries in my experience). I had a set of the DR (Hong Kong) ones on my ST-R, and the centre ones both crapped out real quick (lost pins etc). I ended up replacing them with genuine ones from an RC chop shop on ebay

Going with my experience with their products and their Dragon Racings reputation, I would rather cut off my legs and halul my butt across burning coals than buy their Unis, So Itoo would suggest you go for the Taiwanesse option, unless you can find some GPM options.

thanks for your opinions.
dragon racing has failed you hmm
the only thing that threw me off the cva's from taiwan was the "hardened carbon steel" metal.
i dont know if ts better or worse than regular steel, but if anyone has used hardened carbon steel, even a tiny review would be greatly appreciated.
i do like how they come with boots and pins, keeping dirt out of those joints would definatly help prolong the life of my drivetrain.
i cant find any shafts on ebay for my sp1, everyones got sp2 stuff now.
and if i buy the shafts from kyosho direct, they seem to be the same as my current factory cvd's from my old inferno dx, wich are bent to shyt, they also dont come with pins or sleeves/boots.

thanks again for your opinions.
im leaning towards the hardened carbon steel shafts now.

of course, if i had 250ish$ id get some pro cvd's from amain or meganitro, but i dont so... my buggy sits.

All steel contains carbon, that's why it's called steel.

As another option if you look on the mighty bay you may find a set of Hyper 7 Uni's or CVD's which will fit the 777 perfectly.

hyper 7 cvd's would fit my mp777 sp1?
or a specific hyper7 model?
remember sp2 equivalent wont cut it.
sorry for questioning that, you seem sure of yourself, I just need a definite about hyper7 equivalency.
thansk in advance.

All matter contains CARBON. Steel is a purer form of IRON.


Care to disagree?

We definately have to disagree.
Not all matters contain carbon. Pure Iron (chemical symbol Fe) does not contain carbon.
Steel is not = Iron.
Steel is an alloy consisting mostly of iron with a carbon content between 0.02% and 1.7%, sometimes higher.

my thread but your argument.
both helpful to me because...
...perhaps the fact that one of my future drive shafts mentions that its "hardened carbon steel" perhaps that is their emphasition that there is more carbon, making it... stronger?
keep arguing im learning more and more about alloys and compositions and things with molecular structure.
cheers.

They use the word because it sounds good. All steel contains carbon, that's what makes it steel. A higher carbon content can make it stronger but also more brittle. It's all in the heat treatment.

This is not an argument, it's fact. Steel is and always will be an alloy of iron, carbon and in some cases other metals like chrome and molybden (ChroMoly Steel) or vanadium.

Just search for the definition of steel if you don't believe me.

I have just been searching and have now rearranged the pathways in my brain to reflect that Steel is an alloy mostly made up of Iron.

LOL


This blows, we agree again.

speaking of re-arranging brain matter imma go smoke one.
thanks all of you for your imput
im getting the hardened carbon shafts with boots and pins included. for 40ish bucks.
everything else that buddy left out of my sale i must either get from kyosho, or 3or more different salespeople.
I think il just buy the crap stock parts from kyosho, get them all in one deal, then take any parts that need to be stronger to a machine shop, and see how expensive it is to get real parts made.

cheers-sorter

heres a pic of my car before the massive upgrade, what a pos...fun...but damn lol

Duude! What the he**!

If he told yoy that was a MP777 SP1 he really screwed you over. It's not even close.
Hopefully I'm missing something here.

I was just thinking the same thing, what the hell is that? Looks pretty old too

A Inferno DX? judging by the engine its at least 10 years old

that is a kyosho burns i think all the kyosho infernos/mp's all the kyosho rally cross buggys are based on that i think they are woth quite a bit if in good condition

oh sorry.
nah this is my old buggy picture, i bought this buggy for way too much, 225$ with all tools/gear.
yes its an inferno dx, it had an os .21rf-b but i blew a bearring in it and i dont want to track down parts for an old engine.

i have no pics of my sp1 yet, its sitting on my coffee table waiting for my driveshafts, engine shims, front suspension parts... all the crap that rcwaffle forgot.


~~~edit~~ included my only pic of my mp777, not much to look at, but ive got one, and not scammed into a dx instead
this is before i've got to it, i have some stuff hooked up now.

He did send the diffs and shocks right?
Otherwise that would be another $200 worth of stuff to get. Hope you got a good deal, hopefully not more than $100 if you didn't get any shocks or diffs.

The center shafts were supposed to be included, they were forgottten.
the shocks were not included in the sale, i meerly assumed mine would fit. i found a set for about 40$ though.
other items that were forgotten were for the driveshaft end of the differential, they hold my suspension arms in place. i will orde them from kyosho, cus sp2 wont fit.
i also assumed my front or rear cvd's would fit, they fell short.
so this 6 piece, plus pins/boots from taiwan is my best, and second cheapest option.

i got my chassis for 80$ us or 79 cdn lol

ok, as promised, il do my mini review on the mystery foreign driveshafts i purchased from taiwan.

first, they came exactly as shown in pictures.
all parts included (6 shafts included, 6 boots, 4 pins, and 12 alan screws, 6 spares)

now, for the bad news.
they are not exactly 100% perfectly immaculate and streight.
they dont seem weak, the vibration is not noticible when running even at top speed.
but, i can see it is not perfect, and for that reason, il never buy these again.
also, the rubber boots take away tuning options, for instance.
if u want to lift the buggy up, the rubber will rub on your a-arms.
i dont usually run my buggy that high up, but if i go to a gravel pit, i want alot of clearance to keep up with my friends t-maxes.

il rate these 8/10
2 points docked for
1 for imperfection
1 for those bulky boots.


thanks to everyone who helped me decide wich shafts to get, these are much better than the other ones i could have gotten. no worrie

and one last question
can anyone verify that the hyper 7's drivetrain will fit my mp777 sp1?
if not, no worries.

I am looking something stronger center diff and other possible options for my Ofna Ravager whenever I plan and need to replace it. Does anyone know what other diff can I can use that would be a direct fit for my Ravager ?

Your help will be appreciated []
