Token's life matters
I am in the hotel here in Truckee. I ran and did not quite make the LCQ yesterday and am not runnning super today I decided to install my super 300 cvd's. Sorry for the blurry pics my blackberry does not take very good close up picks.

While installing them I noticed they fell very rough in the rotation. I was told they would have to "break in" to smooth up. I guess the cvd's in my Losi 8ight t, my SC10, and the ones I had in my Axial came pre " broke in" because the were super smooth unlike these. Also there are some burrs that I had to file off to get the supplied bearings on. Maybe these were rushed, but I would like to have seen these spend some time in a vibrating polisher to knock the burrs off seeing that they cost almost 1.5X the cost of the axle they were going in.

Overall They are not exactly a drop in, but the look like the will be super strong.

I will take my Berg out to the course and run it to see how they perform and update this later today.

the rotations do break in and smooth out! it doesnt take that run time. the cvds are built with very tight tolerances(much tighter than all of the above mentioned brands) Hence why they are almost impossible to break. They where intended to spend 4 hours in the polisher before bagging. Since the machinist didnt perform, I went to the machine shop and ran machines all night tuesday night and put them in the bags at 6 in the morn. so they could come down with the guys. i will be up there this evening. I would like to check out the burs, as I havent noticed those on any I assembled.(as u mentioned the pics are to blurry to see )
 
well they are a direct replacment no mods to install these bad boys.
it took me about 20min for mine and yes they are a little tight to rotate but
a couple mins running smooth as butter. a small price to pay for somthing that will take out a servo before the cvd. iam running mine a full epa's
and 11t pullers and not even a scuff.
super dave is the man on this one"thumbsup"

Really yours were a direct replacement? I had to drill out the wheel hexes. Thats made them not a direct replacement for me. And 10 minutes with a file and mine are in. And after talking with the Losi guys today he said that they are probably made to a tighter tolerance than the Losi ones. But the point is that for the money they should have been smooth out of the box.

And the outer drive pin hole is so much smaller than the stock Axial/berg stub hole that I had to beat the pin in. Lets hope I never shear a drive pin. Overall I am not very happy. I would wait until this guy makes another run than fit and work better. PS. anyone want a set of cvd's cheap. slightly beat on and filed.

Sweet.....next we'll have people complaining that they can't break them.

Those seem like some pretty harsh comments! If they didn't fit as you say why not return them why hack on them and them post how bad they are? All the cvds ive gotten in the past were also very smooth out of the package but they also all have some noticeable slop also. These were never stated that they would just drop in your axle all sloppy like. It has been stated from the beginning that these are of higher quality and tolerance standards that any of us are used to on a rc level. As far as the pins being a press fit thats great one less place to have slop"thumbsup" And as far as having to drill out the hexes big deal its like buying a new body and complaining about having to paint it.
 
Seriously? Your bitching about having to do some fileing? Do you realize the the quality and strength of these cvd's? Get over it...


I'm so tired of people complaining about everything good

Sitting here with dave now, he told you he wanted to see them today, but you didn't approach him.

He said to make sure and find him tomorrow.
 
Just to add my two cents the Bully axles that I produce have a tight tolerence and the cup and ball needs to break in just like the super 300's. There's nothing wrong with this just add a little silcone spray to help them smooth out. Let Dave take a look at them and I'm sure he will help you out with what ever kind of problems you may be having.
 
i aplaud your true honesty on all the productes that you buy ted"thumbsup"
its funny to see everyone get all on the defence when some one pays full pop for something and then gives there opinion.i'm sure they r fine and work great i will pick some up my self soon when i get back into crawling.
for now keep up the good work on the testing of things:mrgreen:

I was not around the comp until tonight. He found me and we talked. Dave is a top notch guy and understood my issues. I think my frustration got the best of me today.

I got them in, and working. They should be strong. They are real tight. I had to do a little file work, and replace the hex drive pins with new ones. The old ones were not gonna fit.
 
I too bought them and received them at Worlds in Donner.

I had prepared for the few things, but not all of them. The fit and tightness of the CVD joint after running 2 days (one practice down the Donner Pass and 1 day on Saturday) they have free'd up just fine.

Issues I noticed were the coating applied to resist rust and such was thick causing the bearings to be a tight fit...not too hard to overcome with the tools we brought. The other issue was the Hex pin hole was extremely undersized or there was some sort of burr. Had to run to the local hardware store and buy a drill and a 5/64 drill and all was good then.

At the time of install I was upset, but I think it had more to do with the rush of needed a truck at Worlds. I let the uncomfortable feeling of being behind and changing before a big event really get to me.

Over all a good product, especially knowing the rush these were put in to get us some for the comp.
