My buddy upgraded his head to metal...and purchased heliproz maverick blades...

The two dont fit...the root of the cf blades from heliproz is 3 mm(i think) and the root of the blade holder is 4.5 ish...

Heliproz said to add a washer top and bottom...but I am very un-keen on that idea. Apparently the root dimension has changed over time and the new stuff is 4.5. Anywho....what are a decent set of CF Blades that fit the proper root size?

I flew with those blades until I broke one of them in a crash. I have the metal head and just tightened the screws until I got the blade tension I desired. They worked fine.

bump....
holy cow you guys start a lot of threads...this moved to page 3 fast

well...its on one now
still looking for answers

ps...I would not tighten the blade grips up to take up 1.5 mm for two reasons

A. stresses the metal...
B. the grip will not grap the blade in a parallel way..ie the tips of the blade holder will make contact with the blade first(I would use washers before cranking down on it like that)

But....that is not the solution I am looking for...I want blades that fit.

Are the Align CF blades any good? Does anyone else make the proper size...surely you guys with metal head are using cf blades.

Don't worry, just add 1.5mm washer and this will work just fine.
There is no problem with that, I did it on a number of other helis
to fit the blades into the grips and there is nothing to worry about.

Adding washers to the blades is a done thing on most nitro heli's we use them

The distance is NOT 1.5mm .... the Maverick blades have a root thichness that is EXACTLY .51mm (1/2 mm) thinner than the stock blades. You can tighten the blade grips without distortion or you can make a set of blade shims using .025" shim stock available from your LHS .... either way works. These blades are excellent and are exceptionally strong and will not increase your current consumption (unlike other carbons) due to the EXTREME quality of their construction. I am currently flying these blades with a headspeed of 3200 RPM and the machine tracks like it is on rails. I wouldn't even attempt to fly Align carbons at that headspeed! Haven't tries the SABs yet, but I cant see how they could be better other than the addition of blade weights.

plastic blade grips vs metal...
the plastic grips are closer to a fit...the metal ones are more than .51 mm out....it is a solid 1 mm if not more.

I measured the mavericks to be 3mm and the stock blades to be 4.5...that is a big difference...

Nitro birds...I fly nitro.....no washers on blades...and the only one that I know of that did it was ergos and vigors...and they had a specific part that took up the difference in blade roots...not just a simple washer...much larger and more surface area..

I can't believe I am the only person who thinks that things should fit properly...and "rigging" a fit, quite frankly scares me.

----------------------
I just went to SAB's web site and their blades have the proper 4.5 mm root...so I have found one source...sadly most manufactureres are not giving the root dimention. Heliproz has one size and SAB another,so it might not be a bad idea for them to do so...hope they are reading this.


I am still interested in what blade choice (with a 4.5mm root) people are choosing though.

Washers are an accaptable and practiced method of taking up any space in excess in the blade holders.
Look at the Raptor 90, stock is 14mm(I'm guessing) but they supply washers with the kit, and most blades so you can use the 12mm root TT carbons.
If I only used blades that fit the blade holders exactly, I would be stuck with woodies most of the time.

Just remember -- if the world didn't suck, we would fall off.

You know, it's really funny !

I just measured two pairs of Maverick blades and they BOTh has 4.0mm root thicknesses ....... maybe your calipers are broken !

I fly these blades religously and they perform outstandingly!

If you got a set of Maverick blades with a 3mm root, you got a defective set ...... Return Them !

funny thing

Ok...I am almost f 40...and my brain aint working

called my buddy and had him remeasure the damn things

blades are 3.92 almost 4mm sorry about my brain...
blade grips are 4.75mm

still to much space...the blade rattles around in the grip.

as for using washers on raptors...spacers yes washers no....

and SAB and Vic sell 14mm root blades for a proper fit...that is what I choose to do...

Sorry for my miss information...but 4.5mm is the right size for those grips and thats what we will use

Go to your local hobby store and buy some .028 (.71mm) stainless steel and make some spacers. It comes in a strip the right width, so all you need to do is cut squares from it and drill a 3mm hole. You will only need one per blade and place the spacer UNDER the blade. I have flown my Mavericks both ways (with and without spacers), and there is NOR difference in their function. Additionally, the metal grips will not deform when tightened to accomodate these blades (I routinely flew both the Maverick and Align carbons .... just swapped blades and flew).

I use the Align metal grips and usually fly woodies. I always end up having to sand the roots on the blades because they are too fat to fit the grips.

At least the Mavrikks come from a different source so they have a valid excuse for not fitting correctly. Why dont Align's blades fit Align's grips? I'd rather shim than sand so guess I'll be buying some Mavrikks.

If you need to use spacers, there is nothing wrong with doing that. It's a common practice in the heli community, and many blades sets actually ship with a set or two. That's a silly reason not to use some very very good blades on your T-Rex.

I had to make some 1mm spacers to fill the gap when I put GCT blades on my Trex, I just used 1mm plywood because I had it handy and its easy to cut with scissors – had no issues with that.

When I upgraded my Eco8 to FG blades they were supplied with plastic spacers, and I have had to use spacers on nitro helis before too. Blades are not always made exclusively for a specific heli, manufacturers often make blades that fit a variety of similarly sized helis, so spacers will be required on some helis. Now if only heli manufacturers could agree on a certain grip size, then the blade manufacturers would be able to make blades that fit perfectly.

missing the point...
When someone sells a set of blades and states it fits a certain model...I expect them to fit...no spacer no washer no plywood (wood will compress so I am really not sure on thats a good idea)

spacers

washers

huge difference

The Maverick blades are NOT made exclusively for the Trex ...... they are GENERIC E-Heli blades. Since the Trex is the most popular E-Heli out there, they chose the lengths that matched the Trex (A lot of other E-Heli's other than the Trex use these blades, some of which have a smaller root thickness requirement).

all well and good...
but when I buy them...tell me they don't fit or might not fit depending on what version I have...

Simple solution really....everyone should list their blades by size...like v blades does , length, cord, and root and type of airfoil.
no question..
no doubts...

then I can choose if I want to mod it to fit.

A set of spacers isn't a deal breaker for most of the people who fly. We realize that in life, there is no "one size fits all". If you wish to deny yourself an extremely good set of CF blades because they don't come with a few pennies worth of spacers, no one is stopping you.
