Arnie I'll go thru my setup tonite and post them here for you. It will give you a good head start atleast... I'm still playing with the pitch and throttle curves. I would like it to be alittle more linear as Gary said. I think it's just a math thing now....Tom..... No "D" flying....

Tom,
Thanks again, I'll setup my blade cp first than the FP Elite hummer.I'll have a project going seperate and BL with belt drive on a honeybee soon. That project prompted me that I better get a radio.It was in the 30's today and not much wind so I got out and had three flights. felt so good to have more room to fly compared to the house.

I know the feeling I'm itching to get outside and do some FF instead of just hovering, terrain flying (over the couch and chairs) and buzzing the cat... It's supposed to be near 50 by wed so maybe I take half a day and just do it.....Tom..... No "D" flying....

Good for you Tom ,New York seems to have higher temps than Michigan in the winter. I like your discription of flying in the house ,the wife could discribe my flying in the house in one word "Grrrrrr"

I flew my CX from the Guest bedroom through the living room and dining room into the kitchen where Heidi was cooking. A very stern look was followed by her saying, "A small boy would get a spanking for doing something like that!" I now tend to restrict my house flying to when she is not around

Tom,
The math thing you mentioned is simply 0,25,50,75,100 in all modes. I know some say limit the amount of negative pitch when just learning but you have to learn someday. Also setting up pitch curves that way eliminates the possibility of the Heli hopping up or down when you change to Idle Up.

Arnie,
First thing to do is print out what Gary posted about setting up the radio. Everytime you reread it, and you will reread it alot, you will find some more hidden wisdom. Getting the swashplate level and setting the servo direction is the hard part but once you get thru that is just finding what you have to work with and get it set as close as you can before you try to hover... Do everything with the motors unplugged......
Here are my setting: set radio to PPM mode first
ch1 N ch2 R ch3 R ch4 N ch5 N ch6 R
D/R ch1 100/80 ch2 100/80 ch4 100/95
end point adjust ch1 60/60 ch2 60/60 ch345 100/100 ch6 70/70
trim ch1 -24 ch2 +36 ch3 -20 ch4 -48
I haven't set any expos yet

normal throttle 0 25 50 75 100
normal pitch % 46 53 58 60 65

Idle up throttle 100 75 50 75 100
Idle up pitch % 21 36 56 58 64
throttle hold -10
revo mix down -20 up -25
Gyro mixing switch +90 high and +50 on low
This is the important thing to get right first swash plate type is
3-S this needs to be set first....
cha +62 che -93 chp -90
These setting are not set in stone as your bird will have different linkage settings and just plain slop in everything will make it vary.. If you use these as a guide or reference they may be useful to you....
Once again follow Garys instructions and you will fly right thru it once you get the swash plate setup right....
Tom..... No "D" flying....

I have never tried the idle up switch period. But it's something I need to try cause I would like to fly inverted.

Arnie I am trying to get the idle up and normal pitch set at 1/2 throttle to be the same, but I don't want to hit the idle up switch til I'm outside and have room for a wild climb out or something totally unexpected.... I'll keep you posted with what I end up with..Tom..... No "D" flying....

Tom,
I was looking at what you have posted and you really should setup pitch curves of 0,25,50,75,100 in all modes to start! Set all the ATV/Endpoints to 100%. The only reason to have less than 100% is if one or two of the servos cause the swash to go off neutral at full positive or full negative pitch. The amount of travel should be limited in the swash mix ratios and not the ATV's. Combining ATV and Swash Mixing can cause undesired mixing of controls.

My settings are:
All ATV's/End Points 100%
Aileron -80%
Elevator +80%
Pitch +25

These settings give me 6 degrees of cyclic and the swash travel for plus and minus 9 degrees. Reduce the Aileron and Elevator if the bird feels too sensitive.

Once you have all of this setup properly you can then set a Normal Pitch curve of say 40,40,50,75,100 if you do not want full Negative in Normal Mode. Setting up this way will work and not give you any hopping up or down when you switch to Idle ups.

Throttle curves should be:
Normal 0,25,50,75,100
Idle Ups (All) 100,75,50,75,100

The final setup touch that makes this all really work nice is to remove the main blades and unplug the tail motor. Now in Normal Mode spool up the Heli with the Tx in Edit Mode for Channel 3. Go to full throttle and the Red LED will be on solid. Now dial down the high end point on the throttle until the Red Led goes out and it turns Green. Go back up on the Throttle End Point about 5% from this point. Now the Red Led should come on just as you reach full collective/throttle. In the Idle Ups it will come at each end of the collective.

Thanks Gary, I guess I have more work to do with the radio... I'm getting things dialed in one at a time and this is one of the things I need to address......
I still think I might have a servo reversed that shouldn't be and I might just go back to step 1 to see what is going to happen with the change......

The T6EXH radio came today ,it's on the charger so tomorrow I should be able to set it up for my Blade CP and elite FP. Thanks Tom and Gary for all your advice and instruction to give me a head start.

Well I have a problem... It seems like the headspeed is way to high I have 6*of pitch at 1/2 throttle in both normal and idle up1 and the blades are screaming... Should I add more pitch or set the throttle lower at 1/2 throttle I'm at 50% right now in both modes....Tom..... No "D" flying....

Why 6 degrees of pitch at half collective/throttle? It should be zero. What motor are you using? If the stock motor no way are they spinning too fast. Those stock motors, even the AEK 9 tooth motors are not that strong. If you are brushless that is a whole different ballgame.

I use a straight linear pitch curve:
0,25,50,75,100 in all modes.

My throttle curves with stock motors are:
Normal Mode = 0,25,50,75,100
Idle Ups = 100,75,50,75,100

Don't be afraid of a little headspeed! It makes the bird fly better with more stability. And don't forget the high end throttle setup I mentioned in my earlier post.

Hello Tom,
What about your V3? Setting up a FP should be easier I would think ,but after doing the Gary checklist do you need much more than throttle curve and revo/mix?

Gary, I'm running the stock motor and gear I can run it up thru the entire throttle curve and the heli won't lift higher than 1' even at full throttle. This is what is confusing me... With the linear pitch curve you suggest it gives you 50% pitch or 5 degrees at 1/2 throttle in normal mode when you switch to idle up you will be a 0 degrees pitch at 1/2 throttle. Shouldn't they both be the same at 1/2 throttle...Either 0* or 5* depending on which way you look at it?
I will go thru my radio setting again and see if I missed something maybe I have a servo that isn't traveling like it should while under power....

I know this thread is fairly old but I have a question in regards to what Gary said early in the thread.

Gary you said not to use servo reversing but to use the swash mix ratios instead.

May I ask the pros why?
