Mavvrikk, holy SH!T. I have been fighting this flutter problem since my last crash. My last set of MAV's flutterd, but I rev the blade grips. Everything fine. But after my last crash, I said, "Mavs seem to work why change." This time the blade tips go in out of track????Also when I do a tavelling flips the blades sound like crap, I would loose altitude???
FLUTTERING &*)*^$#@$%%&*())*(#@#@
So I check my thust bearings found that I put one in backwards, Cool I thought That would fix my problem NO . Buddy of mine is TT rep said he had some TT blades, "you want to try." Hell yea I will try them . Man, I flew those things today. WOWOWOWOWOWOW problem gone The mavs where great for basic flying but suck for any type of 3-D. The quality, what happend, my fist set the plain white ones where fine for 3-D, I have the ones with the silver on the root now and they "SUCK" yes I said it, "They SUCK".
BYE BYE Mav's, hello TT blades.

Bottom Line
Mavrikk sucks. Not just the blades, but all of their products this includes tools and "upgrades".

I believe that Mavrikk is a Heliproz brand, they push that crap on customers because they get a higher profit margin on the sales.

These are only my opinions.

I do 3D with Mavrikk blades all the time. They don't go out of track any more than any other brand. Piroflips, tic tocs, death spirals all work with the Mavirkk glass and carbons. At least they are in balance, the TT's I have owned haven't balanced as well as the Mavrikk blades.

There are some that have problems and some that don't. IMHO, you still may have a problem in the head or collective system that you haven't found yet. The TT's are a little wider and heavier than the Mavrikk's and this may be a contributing factor.

You guys should have a serious look at the new CXD blades. They're beautifully finished, very stiff, taper from root to tail, have a wide chord, and fly .... well just ..... beautifully. I reckon they're a bargain at US$70 (cxdblades.com) as an internet order. Made in the US of A, no less.

No, I don't work for anyone, just had the pleasure of running them on my Raptor 50.

Thanks Doug.

@ Tmoore
You got a point, it so easy to point the blame on something when it has been beaten down so hard in the past. I will take another look, but in the beginning I had this problem, the fix was rev the blade grips. But I take another look. I feel if it works why break it.

I tried the reversed blade grips with the wood and cheaper glass fibre blades, to no avail. Now use only good CF blades, and (guess what?) no problems.

Have used NHP, SAB and CXD, so can compare them against one another. Currently the CXD has my vote, with the SAB as a very good alternative.

I don't really want to spend hours setting things up to compensate for variables like cheap blades, when I can bolt on, and fly the afternoon away.

Cheers

Rogue123,

In my case I was flying a Raptor 50V1. The machine was flying great out of the box and I had it inverted and a link came off and the machine settled to the ground inverted and took out a set of blades, a feathering spindle, flybar and tail boom. After the crash I went through all the links and anywhere that there was a tight link I swapped it for a Rocket City link and ball. After that, the woofs started. I systematically changed back to the TT links and put up with some increased friction, then I swapped out to a V2 head, to no avail.

While I pondered my dilemma, it occurred to me that I was missing something here. I had already tried wood blades, Mavrikk blades and TT blades. The only thing left in my bag were a set of NHP's and these did it too. After looking at everything I decided to machine a new stiffer feathering spindle because everytime the rotor head would woof, the woof would take out a feathering spindle. At the same time I replaced the collective arm on the Raptor with the metal unit from Rick's for $30. This did the trick as it stiffened up the collective mechanism to the point that the woofs no longer happen with any blade that I run.

A smart man told me one time that you either have to have blades that are CG corrected and stable or a very stiff collective system to maintain control over the blades in terms of tracking and control stability. When I freed up the links I systematically introduced more freeplay into a system that already had too much of it.

I had flutter on a rap 50, replaced the head with a v2 and the collective arm with the thicker V2 one and it curred it.

I also had it on a Rap 30 after botching an auto, replaced the blades and I got flutter. Apparently is all to do with lead lag timing of the blades. NHP's curred the problem because of the lead lag balance Cant rember the tech term but when you hang them from the bolt holes the NHPs had a differnt centre of gravity.

I reverted back to the originals and just replace the collective pitch arm with a V2 its been alright since.

I haven't bought alot of Mavrrik parts but all the ones I have work fine. The Carbon G4 blades have been great, although I don't do hard 3d, they track fine, including a couple times I really overspeed the head. I have heard complaints on the "Value Carbons" Just my $.02

i also have had touble w/ the mavrikks, but only only with a new set after acrash. buuut heres the kicker my stock woodies work aaand my nhps work. i think it has something to do with head speed. my weston needs a higher head speed and i beleive that has something to do with it. i also do not think there is a prblem with the PRO blades, just the carbons that come in the dlx crash kit i would use them but even in a hover they flutter not just in hard maneuouvers. i heavily recomend NHP's as an alternative not much more money for a high quality blade. no that it matters much in the grand scheme but it was just my $0.02 worth

Rogue123,

By chance did you call HeliProz and give them an opportunity to correct the issue? Or did you just decide to go ahead and slam them?

I too had problems with some of the original Mav blades and they took care of me each and every time. I had found that the original Mav blades seemed to be manufactured to have an aggressive (unstable) cordwise CG and this coupled with manufacturing tolerances compounded the issue. Having said this, there are going to be “bad” sets out there. I have found this to be true of the TT blades as well.

Also, do you take the time to check the CGs (cord and spanwise) and balance these blades? I have yet to find a set of Mav and/or TT blades that were matched.

In short, you get what you pay for. A lot of folks expect to spend $70 and get the consistency and performance of a $115 set of VBlades. Folks need to understand this and deal with the challenges associated with it. This is not to say that the $70 blades should not be useable, but one should expect to have to work them and in some cases send them back for a new set.

Just my .02

AFT CG
The Mavrrik blade has an aft CG. It makes the blade very aggressive. It may make it the best "Flippin blade" but it will go out of track on a lot of machines. The easy test is to hang the 2 blades leading edge to leading edge from the bolt hole. The blades will lean towards each other meaning an aft CG. Just like an airplane, if you move the CG back you can get a more agile airplane to a point, after that it becomes unstable. Same concept with blades. V-Blades, NHP, TT blades are more neutrally balanced while MS and Mavrrikk have a more aft CG.

The pro mavs flew fine and I whipped on them hard. All the TT600s I've seen and flown performed great.The early mav blades have given them a bad rep(well deserved).The g4 pro blades do seem ok now.I would not take free older model mav blades.
