I have a fury expert, with OS70 (new), 9252 on everything, 401, revmax gov, GMS Main blades and sab tail blades. The collective is +-10 and the cycle is +-6. I set the evelator at 110 end point as well as the ailerons. My swash is set at 60 on each surface and I have a headspeed of 1500 in normal and 1750 in idle 1. I'm using a futaba 9c super.

My problem is the heli flies like a worn out dog...the flips and rolls are so slow, I can have a cup of coffee before it makes a 360 flip or roll....Climbout is very slow...and I do have the neddles set correctly on the engine....Tic-Toc's are very slow as well....

This is the original fury 60 expert that I bought on RR...I thought the engine was worn out so I put a new motor and it still flies the same...

any suggestions for you guys.

different paddles might help also try running a higher head speed, say 1850 also you could increase your cyclic throws to 7 degrees.

I guess you are slightly limited by how much power the 70 is kicking out.

I forgot to say that I have V-paddles and from what I have been told, the 1750 headspeed should be perfect for the OS70, but to me 1850 sounds better also.

I thought the V-paddles would do that...

The V paddles will also give the quick response. What is your battery setup like? How is the voltage holding?

2200 mah battery, 4.8 and seems to be ok....I think I will put a formco regulator and battery and run everything at 5.2...I know that will help.

Head speed and cyclic pitch. I dont know about a 70, gear ratios etc. But I fly a Fury Extreme 90, and I run 1950 on the head, 11 degrees pitch, and 8 degrees on the cyclic. I would like 9 degrees of cyclic, but everything is on edge (binding wise) on the head now at 8 degrees.

Timing is everything

Try some 680-690 main blades and bump the HS to 1800 or higher. I would only go for +-10deg of pitch though. Check your dual rates and expo as well.

Thanks guys, I will try 1850 tomorrow and see what happens. The blades are 680 carbon and I think made in canada...seem to be ok...I tried 690 mah blades and no change...Just think the headspeed is too low....even at 1750....

Dumb question here .. What Rotor head is on your expert and what length flybar?. If it is for sure the stock Expert head you might look into what settings the bar bar/blade ratio and also what dampners are in it...

If in doubt lean it out . We don't do this to save money, we save money to do this

What Is The Weight Of The Blades?

Lighter Blades Make For Quicker Response, Try To Find Some 170-175 gram Blades.

Stock Expert 60 Size You Can Run 690mm and 105mm Or 700mm And 95mm.
+-10 Degrees Is Good To Start With, You Can Do +-12 degrees Pitch If You Have Really Good Collective Management, 6 Degrees Good To Start With, Ive Done 8.5-9 Degrees Of Cyclic Before, Just Be Careful not To Go Into The Corners And Add Too Much Collective.

That Thing Should Roll a 360 In About a Second, Ask CForcht ABout The Fury I Set Up For Him, Last Fall! Now That Had Some Roll Rate!

Im Currently Lightening 2 Fury Extremes And One Expert Should Be 9.25-9.5lbs RTF Minus Fuel When I Get Done With Them.

Just Enjoy The Ride!

Karl,

Thanks for the comment and I will try what you suggest. The mains are 195 grams and from what you say, I would guess they are too heavy. What brand mains do you suggest... Also, I just installed a MPII for the pipe...should be better on power...I'm also running the headspeed at 1850...should I go higer or lower.

White paddles are quicker than V-paddles. Do like kevinb902 said and try the white ones, you'll like it. You might wanna try a longer flybar also.

I have just about the same setup on my Expert.
Your problem is somewhere else.
I just changed over to a YS80 but more as a wanting to do then it being necessary.

So until just recently the setup was:
OS70/MP2
Fuel: 20/20
RX battery: 4.8Vdc 1700mah Sub C
Servos: 9252's
Gyro: GY401/9254
Paddles: V2 95mm
Blades: V2 690mm
Tailblades: Carbontech 95mm
Headspeed: about 1650rpm

IF I would want a cup of coffee while doing a role, it better be injected introvenious.
I am not a hardass 3D pilot but flips/rolls and other stuff are the order of the day.
I 1st had the original MA white plastic paddles on it and then swapped over to the 95mm V2's. The V2's are faster on full cyclic deflection, but more stable/better tracking in fast forward flight and less sensitive/pitchy around neutral.

I would recommend to replace your head dampers 1st.
Also check the amount and what size washers are installed between head and Blade Holders, as they also determine the stiffness of the Head.

alfred,

Thanks for the setup information...I tried a set of mha 690 this morning and that seemed to help but my forward flip is really slow. My roll rate is fine and the back flip seems ok. I am running 105mm sab tail blades but plan on changing to 95 v blades. My headspeed is 1850 and that seems to be ok on the MPII pipe.

what dampners are you running on your expert and the washers are what size???? I want a very stiff head....I will call the LHS and see what they have in stock.

MA came out with single piece damper instead of the double "O" rings.
It's part number is: 844-12.
IT comes with 2 washers (one per side). These apparently are very stiff and will cause Mast bumping if the head is run too slow.
They are designed for all out hard 3D and from the word around will also last a lot longer.
So, they would be my 1st choice of change.
Just go through your setup and follow the manual to the letter.
As we both seem to have flown the exact same machinery, it can only be somewhere in the setup.
Stick with the V paddles.
The next upgrade that does increase cyclic authority by a noticeable bit,is the Flybar carrier upgrade that you see on the Stratus.
Here are the upgrades that I did for the sake of upgrading only (boredom, need to have the latest and greatest, little time and opportunity of flying..got to do something.. etc)
Upgrade OS70 to YS80
Change gear ratio from 9.3 to 8.45
Upgrade to the latest Flybar Carrier
Longer Flybar

Result:
Vertical performance close to my Stratus
Noticable increase of cyclic "bite", again very close to my Stratus.

None of these were required as it could do more then I am capable of in it's original form.

But she was just fine in her original form and none of the above were really required.

I will order the dampners this morning and also check on the flybar carrier and longer flybar.

I do appreciate the help and I know this will make the Expert fly better.

Alfred,

What setting do you have for the swash AFR...The MA manual says to start at 60 percent for each setting...so...did you leave it at 60 or did you go higher.
