I have been trying to figure out how I can increase the roll and flip rate. This unit is on my trex 550. It rolls much slower than my whiplash with vbar. I have checked for full travel with out binding. I have parameter G set to solid blue. Dual rates in dx8 are set to 100%. Any suggestions?

Thanks,
Chris

I have to guess you are talking about a microbeast unit since no others have a parameter menu in colors.

IF SO:

set parameter G to default

and set parameter B to transmiter mode (blue). keep the dual rates at 100%

hang on, is going to be quick now. Dial the D/R lower if too quick.
If it still not fast enough, try better blades before bumping parameter G.

good luck

Assuming you are talking about a Beastx controller, you can also try setting parameter B to solid red or blue flashing. Default is red flashing which is the "sport" setting. Red solid is the "pro" setting and blue flashing is the "extreme" setting. I run my 550 on the "pro" setting and it flies pretty good. Not lightning fast, but plenty fast for a large heli and very controllable through 3d flight. These settings are nice because the heli flies/flips very uniform in all directions without any further setup in the transmitter. It handles all of the dual rates and expo in the beastx itself. It also makes switching between different helis very easy since they will fly very similar when using these settings.

The sport setting is good for sport flying, but pretty slow for 3d. Setting parameter B to Pro or Extreme will definately speed it up compared to the default setting and it keeps everything uniform in all flight directions without any tweaking in the TX. Like moneypitvictim said, you can also set this to transmitter mode (blue solid) and use your dual rates to make it flip as fast as you want. Be cautious on your initial flight, depending on how far your limits are set up in the standard setup menu, the heli can move extremely quick and be very touchy until you get all of the dual rates, expo, etc set up in your transmitter to the way you like it.

Just to be clear I have the AR72000. I currently have parameter menu B, control behavior, set to solid blue, transmitter. And have run parameter G, cyclic response, up to solid blue-very high.

You you are saying to set the Cyclic response to User Defined also and then use my dual rates to control the amount of throw?

I'm flying Mavrikk G5 blades. Much snappier than the Align ones.

Thanks!

If parameter B is set to transmitter, you should be able to raise your dual rates to make it flip quicker. I haven't messed with parameter G on my 7200s so I don't know how that setting will effect the heli.

Set very high, Parameter G can give you a very odd feel in cyclic, like you are chassing it. Same as pitch boost. Best to run to run both at default.

You are not going to acchive a faster cyclic rate than in Parameter B set on transmiter with the TX rates cranked up.

BTW, Do not run any cyclic expo.

Where you able to get a good cyclic resolution when you set the cyclic 6 degrees?

Are you saying to move my dual rates up past 100% to speed it up?

Why wouldn't you run cyclic expo?

BECAUSE expo will SLOW DOWN the initial rate of rotation.

With an FBL unit you are commanding a rotation rate. The rate is linear with the stick and does not need expo.

Also, Some FBL units itself has some built in Expo.(BeastX does on the presets for Parameter B but not on transmmiter mode)
I dont use expo on the cyclic, just reduce the total rate (D/R) if I want to slow it down. I DO USE expo on the tail.

(Expo decreases the amount commanded initially and then rapidly introduces it back, it is mainly usefull for mechanical servo arch compensation and achieve a linear feel.)

Please, go to Zero expo, 100% dual rates, Pararamer B on TX. try it again.

Yes but only decreasing the rate at center stick. When I was taking a class with Matt Botos he said to always use it for the compensation you mentioned.

If I hold full forward elevator I am out of the expo range and it is flipping slow.

Santiago, which parameter are you suggesting for menu G?

Leave parameter B to transmitter, D/R's at 100%, and increase your ail and elev end points to increase the max flip/roll rates to your liking. just make sure to do both endpoints on each channel and make them the same value. Mine are at +/-125 to get my rates to where I like them. Hope that helps.

beating the air into submission...........cool!

Whatever is the deafult for G, (purple).

Follow what dcbusdriver said to increase the rate,
- D/R @ 100%,
- increase the endpoits to 125% if needed.

BTW,
Botos flies a CGY750 which has a nice expo menu inside the gyro that maintains the resolution and decreases the rate near center stick. The VBar has it too. beastX dont.

For anyone who has the wanted cylic rate at full stick and feels it too quick at center stick, expo makes sence.

BUT, Expo is a hinderance for someone that has feels the cyclic reaction is too slow to begin with.

another limiting factor with achievable cyclic rates isheadspeed.. maybe you need to increase your headspeed along with your beast parameters.

i also run a Spectrum Beast on my 550.
Parameter B on extreme and elevator and aileron travel increased to 120% it flies great. pussycat at 2000rpm and devil at 2350

I finally got down to the field today and tried all the suggestions. The only one that worked correctly was increasing my servo end points. I have them set at 140 and its nice and snappy now.

Thanks for all the suggestions!
