Hub & Grips, (Stock or Mod)

[Kingacp]

Trying to get an idea form those who have done Hub & Grip Mod, What do you feel is the Best or is it best to leave stock?
Thanks

Love the MH hub. Haven't lost a link yet. and it's lighter if I remember right.

I haven't tried any aftermarket stuff yet 'cause I still crash. A lot. The stock hub and grips have held up through countless inverted crashes.

I do have the solid core cf main shaft from MH, though, as the stock one is easily damaged.

MH hub & grips totally eliminated feathering shaft slop.

I like the combo a lot.

Stock hub and grips on mine spinning over 7000 rpm, hard 3D. Works wonderfully.

Only thing I do not like is the stock hub doesn't tighten on the main shaft leaving some lateral slop after a while. Still fly's good on my bird. I prefer the MH or Xtreme as they grip on the shaft. RKH is alright but it's just a little tighter than the stock hub on the shaft.

I didn't notice any real flight benefits of all the CNC, felt like looks more than anything.

Does anyone make adjustable pitch links as well? I'd love to be able to fine tune the tracking and such on these, even with the stock grips and hub.

I prefer MH hub because it takes up a lot of slop in the links. Also captures the links so you are less likely to lose them, as previously mentioned.

Stock plastic grips seem to be the tightest I have seen which is why I haven't gone to aluminum ones yet.

Ew, no thanks ... if you have a tracking problem it is the blades not the links

[jonbailie]

Why ew? I have them on my genius cp, and the head works much smoother and easier to setup with them. I can never get my mcpx perfectly tracked, no matter what blades, feathering shaft, rotor head, blade grips, main shaft, etc., that I try. I can get it close, and I can balance the blades easy enough, but it seems improper and I end up using much more tape than my genius. Seems adjustable links would make it easier to setup, like on pretty much every other collective pitch machine.

I have used both the RKH hub and grips and they have more or the same slop as stock. I haven't tried MH yet, but I love their swash. The Xtreme hub doesn't remove feathering shaft slop, but does fit very tight on the main shaft, so there is less slop there. The Xtreme grips also come with an extra washer which removes all slop and the grips capture the links.

Not sure how recent your RKH experience was, but I got a few items for reviewing last week. Perfect fitment with zero slop issues for the Grips/Hub. There very well may have been manufacturing discrepancies out there, so I may or may not have gotten lucky or there may have been some design modification.

I will say they need to follow suit of MH and Xtreme and cut the center portion out nearest the shaft on their hub so it grips on to the main shaft itself when you tighten the screw.

I've got the hub and it causes vibes in mine. Swap a stock one on and it's smooth again

[Kingacp]

Thanks for the replies, I mounted the MH Hub & RKH Grips, Seem to work pretty good, I converted to Brushless, but almost feels like I lost All Duel Rates with setup, I'll post new thread to this problem.
Thanks again for the advise

Well my friend got the RKH parts for review about 1 month ago and well I ended up reviewing them, but overall the head is sloppier than it was stock.

I'll post a video tonight as I have my friend's heli at my house. His RKH hub also bent on the first crash. I never bent the Xtreme one.

IMO it adds unneeded weight and parts complexity to a simple machine -- and the simplicity is what makes it so awesome. I have never had a problem tracking mCPXs ... whether brushed or BL.
