Ambro..

The problem is exactly that there are more people coming forward and having problems.

The taper is out.. Or the hard anodising has caused the problem. I just can't believe his negativity at the moment and blaming everyone else.

Just like a lot of new products that promise the world before this..they should test these things on the biggest motor available at the time, send them to people to test rigorously before its released to the market..i hear of some uber zero growth tyre failures also..now they also promised the world

I don't think it's all user error... I read one comment one guy stripped to screws & basically torqued to no return. Not tested it yet.

well this guy has followed all the instructions that was given to him and withing 10 min it started slipping.. Check the inside what your thoughts. this is on a RCmax 46 no different to a standard clutch plate tapper.

The smaller cc guys seem to be having no hick ups. Lack of testing on the big bores before hitting shelves me thinks has led to this. Bet he regrets making them for the big bores.
End of the day hoping he gets it sorted  dontknow for the big cc,s

I can't understand. Why he hard anodised the inside of the tapper. The bigbore engine have over 12 hp some even more. You can clearly see that the crank isn't going in far enough. And is resting on the edge of the taper of the crank. It's just not enough grab. The guys trying to install them have really done the right thing as the bolts that have been supplied wouldn't of bottomed out since the clutch hasn't seated correctly. As for over gearing what would be the point of owning a bigbore if you couldn't do that. Running below  24/50 on a Rcmax to me isn't enough. I don't think the clutch is bad I think the pressure of everyone wanting it took place. Testing needs to be done.  all around the world not just in one area. We expect it in engine what the difference in this. IMO

Hoping they allowed for the micron thickness when doing calculations on the internal taper as it does add half of the micron amount anodised on.That doubles though when it's round. Be good to know what micron they added.
+ 1 on world wide testing and  at least a vid with a big bore.A fan boys twin running on concrete for a minute don't cut it for me  *thumbsdown*

Yep.... Can't see the sense of it really.. No real benefit for it. I'm guessing the tested  ones didn't have it. Let's hope it gets sorted for them, I'm sure a few have gone out.  I have a look at when mine arrives mite have to do some mods on it.

Hopefully for a lot of 1/5th scale guys they will get it figured out, it would be nice to have a clutch that lasted more than a few tanks. :(

I don't know what more this guy can do... He has followed all the instructions that was given to him. There i obviously a problem with design and tolerances in the tapper. its the only explanation.

Like alot of these new products that are advertised as being the be all and end all.. They weren't simply tested on rcmax motors.. What they should have done is perhaps send some to be tested by different owners of rcmax motors and then seek feedback Before it is released to the market.. This allows Any defects to be sorted out earlier.. It isn't rocket science

i think these type style clutch would be better suited to the smaller mtrs than bigger one's

i think with these style clutch system that once the lugs that lock on to the bell wear out these  will be a slippery as a banana ...

qestion is how long before you may need to replace lugs or bell or both..


by the way don't you blokes use damo's ultra clutch how's that been going ???? need a good one for this twin i'm building

Ok guys finally arrived and it looks the part. Its light and is hard anodised all over in dark grey..

After reading the problems that some guys have been having I thought I would start with the clutch plate. My testing is with a brand new stroker crank never been used. Not a Rcmax crank but is tapered the same. I have several clutches & clutch plate and they all fitted perfectly like a glove as soon as you actually put these other makes out seated really well. No movement or feeling of hollowness.  You will see that I took measurements of each clutch & plate. Even a cheap ass so called clutch cooler seated well.  The flat screw hex thst comes with the pack is fine on my crank when applying the snapper clutch plate. Ok on first impression the clutch doesn't seat well IMO and spins around the crank where all the others fit well and actually grab the crank without tightening them. You will will see I placed marks on the crank in red to show you where the clutch taper starts on tne crank and where the TR finishes my opinion stands  there isn't enough to grab orotund the crank as it needs to go at leas anothe 2 mm or more. It just doesn't feel right... I haven't checked yet how far forward it sends the clutch towards the basket as I haven received the basket I'm waiting for which is The standard blackbone to fit a Baja. As I seen that the basket also are short on the blackbone shaft. Which they shouldn't of been. I would put this ad another defect. Hopefully sorted in the next batch.

I may add that all the other clutches seated all the way down to the end of the tapered crank closer to the con rod.

Here are some pick if you have any comments and thoughts would be great.

You can just see that the crank goes all the way up to the top of the inside of the taper seats really good. Feels and grabs no spinning around or hollowness or movement. I don't even have to torque the bolt down to much it locks in hard.


Ok a cheap piece of crap cooling clutch plate even this seats well.

This is a Crank with the line markings where the tapper finishes and the Tr finishes the line closer to the crank is the finish of the taper  And I said above I don't know at the moment how this will effect the clutch from the basket. I will install, this on my T/S. Engine with a clutch holder to test for any friction.

Oops.......doesn't look good.
I have to say that the hard anno will not make anywhere near that much difference on what is a pretty large angle taper.
The diference on the length would only be less than half a mm.
To me it looks like they are either not using guaging or the test guage is incorrect.
Either way it is certainly a quality issue not a fitting issue. 
All in all you are losing about 25% engagment of the taper which is not good..... *thumbsdown*

Mate I'm totally in agree.. I think the sad thing is there is denial and a a lack of proper testing on the bigbore engine.all there's measurements should of being doubled checked not only the taper but the basket.   Remembering that the smaller engine have less than half the hp. May not make a difference for a while. Anyways my testing will commence once I get my basket. Oh I'm going to,take it to a machinist with a correct taper reamer.as to,send it back would cost probably just as much to repair correctly.

Is there anyone here with a Rcmax 46... That is willing to take off there exciting clutch and take a pic on where the clutch plate finishes on there crank. I believe they are saying that there has been 3 diffret sizes of taper used to accommodate a standard clutch plate taper. I could even send you this tr to test the seating of it. But I would require it back. Even thou it's really doesn't seat well on a tankard clutch crank.
