I saw this on youtube last week and I thought it was interesting.




I'm not trying to diss the company (I have the master cams 0-4) just trying to inform

Whats your guys and girls thoughts?


--EDIT, I read the comments and changed the title, good to know that the cams work well

Old news. The jig flexed. MCs are fine in horizontal placements. Gunkiemike

Yes, I believe these are Aric Datesman's tests and he updated the information on rc.com regarding the suspect test rig. Hopefully he'll chime in here to clarify. As I recall, Metolius followed up on these tests and weren't able to replicate the issue.

Yup, old news. Once the fixture was reinforced it was nigh impossible to get the lobe retraction to happen. It took me ~2 hours to find the right combination of insertion distance and crack spacing for the second video, and any deviation on either resulted in it not happening (to the point that it it seems very unlikely to happen out in the field IMHO). The folks at Metolius have looked long and hard at this (I've seen some of their internal test documentation) and I trust that had they found an issue they would have addressed it.

Additionally I was only able to get one of the inner lobes to retract when using the reinforced fixture, which basically leaves you with a 3 lobe cam and seeing as 3CU's work I don't think there's necessarily a problem with it.

Side note- I should probably go overlay the videos with a note saying it's not an issue... I've left them up since they're referenced in the discussions on RC and didn't realize people were finding them without having gone through the discussions. Sorry about that.

-a.

EDIT- The videos are now notated.

Only question now is whether this entire thread should be deleted. I say make it go away. Gunkiemike

Well, it does address this idea that there was ever something wrong with Master Cams and does so in the first few posts. Delete it or not, I don't care too much. It seemed rather ludicrous that this cam would have some sort of unique behavior in horizontal cracks as the cam angles are not radically different than any other cam.

Definitely change the thread title to something like "Master Cam Test Faulty - Nothing to See here"

Additionally, you can't even watch the posted YouTube videos as the embedding is disabled. Red Herring thread. Please, either delete or alter the title appropriately. Joseph Crotty
