Pitch curves

[cmkeene]

What is a good pitch curve for norm and idle1 on a raptor 30? I have read the manual and looked on raptor technique and there different.

I'd be inclined to go with RaptorTechnique, I've never seen anybody say that his info was anything but excellent. Start with one or the other and tune it to what *you* want.

I use a linear curve on my Rappy 30. +-10 degrees with 0 degrees at midstick in all flight modes... Works great :thumbup:

The manual probably reccomends hover pitch (4 or 5 degrees) at midstick... thats old skool :roll:

There are 2 methods people use. First is hover at 1/2 stick the other is hover at 3/4 stick Let me explain.

My set up is normal mode -4 to +12 hover at half stick, idle up 1 -12 to +12 hover at half stick, idle up 2 -12 to +12 hover at 3/4 stick inverted hover at 1/4 stick, throttle hold -4 to +14 hover at 1/2 stick(ok you cant really hover in throttle hold but I have the pitch the same as normal so when I hit the throttle hold the heli responds more predictable (for me)). With all my hovers at 1/2 stick other than idle up 2, I have to remember to either be climbing, fast forward flight, or move the left gimble fast when I go to idle up 2 or the heli will loose altitude fast. In fact I broke a boom brace when I thought I was going from normal to idle up 1 when in fact I was already in idle up 1. I was only a foot off the ground and wam, hello earth.

I don't know if you noticed but I am getting from -12 to +14. I am able to get that because I modified the frame where the pitch slider and elevator go through the frame. The oval slot for it to slide in has a thin raised area around the outside of the slot. If you file just the raised area to match the inner part of the frame on the top and bottom of the slot (both the left and right frame) you will get a bigger pitch range. If you do this mod, on the bench give it full positive pitch and bury the cyclic in the corner, now make sure when you decrease the pitch the swash plate slides down. If you have to move your cyclic slightly toward center position for the swash to move there are two ways to fix it. Either decrease your end points on the elevator and aileron, or use a cyclic ring on your transmitter. Check this with all for corners

If you have not flown yet and still setting your heli up on the bench, a good place to start for where you want hover (1/2 stick or 3/4) is +4.5 to +5.5.

+1 thats the way i have my raptor 50 and trex600 too,

It may be oldskool, but you have much better hover pitch resolution when you use a midstick hover. So, I guess it depends on what you want to do, hanging a cam from under your bird or just doing scale flight - set it up to hover at mid-stick; don't want the "inconvenience" of having to remember to go to 3/4 stick when you switch modes - go -10/0/10. Personally mine is set up for both, midstick hover in normal, full throw in idle up. I don't think having to move my stick a touch when I change modes is so big a deal.

Another benefit to hover at mid-stick is if your radio has Hover Throttle/Pitch functions, it makes it really easy to tune your hover for different conditions.

I use an s-curve for my pitch to get the best of both worlds. All flight modes are still the same and I can hover upright or inverted about 1mm from either side of midstick. I still get almost the same resolution as midstick hovering, yet I don't have to worry about the heli jumping when switching between modes. On my helis running a 5 point surve I use 0,15,50,85,100 and on my 9303 I use 0,10,25,50,75,90,100.

If you ever plan on flying 3d, I would just get used to running midstick at 0. If you are only interested in scale flying and light aerobatics, hover at midstick.

Thanks for all the good info!
