I'm trying to get better cyclic rate for my raven. i currently have the stock paddles with weights removed, Radix 600s(non-SB), and have about 8 degrees of cyclic pitch. it takes a little over a second to do a full stationary flip or roll. i didn't clock it but it seems slow. has anyone gotten to compare the stock paddles with afermarket ones and have recommendations?

The stock paddles are actually fast enough for general use. I did change mine over to the V paddles / CY Stubd and noticed a slight increase in cyclic. You need to check your ATV throws. It might be a tad low. Increase it a bit and you should be able to do the stationary flips. I've also used Miniature Aircraft 3D paddles and they seem to be a good choice too.

Century also sells some light paddles as replacements for the Hawk/Raven lines. They are also good.

do you know your Head Speed ?? if your down around 1700 you could go up to 1850, even 1950 if you have the Gray Counter Gear,,

do you have full Swash deflection without binding ?? if you do not have full deflection then as Ray said you need more Servo travel..

headspeed is 1980. i have a little bit of binding at full deflection but it only happens under full neg collective. i don't do both simultaneously so i went ahead and set it up that way to get as much cyclic rate as i can. collective pitch was +/-12 but i felt there was too much binding so i brought it down to +/-10.

For me, I normally run +9/-9 on my machines. I found out that it is really about getting optimum engine performance to get your heli to do some wild flying. Your headspeed is good (for me anyways )

What cyclic responses are you looking for - similar to a 450 electric or what?

The over large pitch settings you have set could be the culprit, as any combination that total's more then 10 degrees or so would probably bleed off rotor speed very quickly.

What will bleed off cyclic response very fast, is decreasing rotor speed under load.

If you load the motor and the rotor slows just 100 rpm (yet your ear may well nt hear such a minor difference), the cyclic will bleed off very quickly - with any paddles. So what system are you using to insure there is no change in your rotor speed under cyclic loads?

Are you using a governor to insure a constant 1950? Throttle mixes?

Try a set of stubbs or century has light carbon paddles also not sure the part number. You want big and light like the stubbs

The CY even the stick bangers are a more stable blades than say a 610 rotortech.

The Raven paddles also were too slow for me as well with radix blades. With the stubbs it was really lively and I did not need lots of cyclic as Oldbyone mentions above no bog and lots of active responce.

Dumping cyclic at the issue is not the way to go for sure. Like driving a race car loose is fast

With the stubbs it puts you over on the other side to scary fast and comes with weights to use to fine tune it to taste

I agree beavis1, but only if his motor is keeping with the loading he is giving it.

Once I am sure of that, then it is worth moving on to other items.

i'm using a governor to hold headspeed. in a roll, it doesn't sound like it's bogging, just slow. what's my definition of slow and what do i expect? i want it just fast enough so i feel connected. right now, it feels like the heli is lagging behind my inputs which reduces my confidence.

8717s but on a 4.8v nimh. when i was hovering around and just doing FFF the nimh held it's voltage ok but a few quick pitch pumps will make the voltage drop to the low 4s even with a fully charged pack. i'm putting a kiwi with A123 at 6.6V system on soon which is more appropriate for these thirsty guys.

as for trying to speed up cyclics, i'm gonna give the super stubz a try. just ordered a set last night from grandRC.

you should get those 610 Rotortechs, they will quicken things up..

Yes they are just fantastic blades ! Make sure the 610 3D they are the fast ones.

Also by stock paddles there have been a few flavors some faster than others. So paddles are still on the table to define you have the lighter larger sized ones. Just to keep the advice on the same page.

Yes, I should have said master Oldbyone

i must have the worst heli-willpower. i had a few minutes break at work so i drove to heli-world down the street and got the 610s. my reasoning was...well you're gonna crash sooner or later so you're actually saving money since they are currently on sale.

right....

That's some sound reasoning.

Yea I am sooo glad I don't live that close. I would be divorced, but have lots of heli stuff to keep me warm at night

the past 2 weeks has been bad - i really fell off the wagon

- rotortech 610s
- super stubz
- kiwi regulator & duralite A123 battery
- fuel magnet
- 92mm radix tail blades
- case of byron rotor rage 30%

canbarelyhover,, I forgot about this, buy the Metal blade grips for your Raven, they will quicken up your cyclic and make your cyclic feel lighter,,

http://www.centuryheli.com/products...05&prtnm=CN2557

something else we didn't think of, are you using the Red Head Dampeners ??
