Please help me understand...
What is the best way to "calm down" a Blade 450 3D's responses to accelerating forward in response to right stick inputs? I'm OK with hovering in all 4 orientations, but I have limited space in my yard for forward flight, so in order to do figure 8's, I'd like the forward flight to not reach mach 2 in 20 feet!
I'm currently running 60% and 20% on D/R's. Is travel adjustment where I need to go next? All are set at 100% at present. Thanks and Happy Thanksgiving to all. DH

What are your pitch and throttle curves?

Pitch is 40/55/72/80/90
Throttle is 0/58/75/80/90 DH

Don't move the stick so far, seriously! Limiting the travel is the same as lowering the rates. Just keep lowering the rates until you get the reaction you are looking for.

OK, thanks. How's the weather in Minnesota???
I was out practicing hovering and figure 8's this morning in a light snow shower. Kinda pretty. Anyway, thanks again for the advice, fellas. DH

It's cold, around zero today. You could try lowering your throttle percentages at positions 3, 4 & 5. You don't need all that head speed when you are just practicing in a small yard. Your pitch should be close to zero at mid stick and it should start to lift off between mid and 3/4 stick. Your pitch values seem a bit high. Have you checked the actual pitch with a gauge? I'd try lowering the pitch settings. You want about 5 degrees when you get near 3/4 stick and probably about 9 degrees at full stick for the type of flying you are doing.

I'll check the pitch after coffee (LOL!) and not before! I thought higher head speeds translated into more stability...but I see your point. Hmmm....the complexity and nuances of all of these potential points of adjustment make this quite a challenge, doesn't it!
Never really had this much to contend with while flying airplanes! Once again, thanks for taking the time to provide guidance. DH

It will all eventually just make sense. You will want more head speed once you get more comfortable and start flying around faster. Also, the more pitch you induce while flying, the more throttle you will need to maintain a certain head speed.
All of this is assuming you have zero pitch when your left stick is in the middle. At what point does your helicopter currently lift off and hover? By looking at your current pitch curve, I would guess way before you get to the middle. If it is lifting off before you get to the middle or right at middle, try these pitch curve settings, 35,45,55,75,90 and see if that makes any difference. Then try a throttle curve like 0,45,65,75,85. Mess around with both of these until you find what you feel comfortable with. If the motor starts to bog down as it starts to lift, increase positions 3,4 & 5 on the throttle curve 5% each until it doesn't bog. |

When you say that you have DR set to 60% and 20%, you mean that you have DR set to 60%, and Expo set to 20%, right? If so, then I think your expo is about right, and I wouldn't go any lower on your DR. If you do, you'll find that you quickly reach the limits of your control envelope. The best advice I can give you is to get more practice in a larger area. If you really want to fly in your yard, then get a smaller heli. If you can find a 180CFX, that would probably fit your needs perfectly. Good luck!

So this is my setting in Stunt mode:
throttle curve is flat 80% Pitch curve 45% 51% 60% 91% I too would like to calm down the 450 for backyard paractcing. I was flying at my Dad's place and he has more wide open space and no neighbors so I was doing ok, but found flying in Normal mode instead of Stunt mode was much easier and more relaxing. I keep thinking I have to fly in CP (stunt mode) but FP (Normal mode) is nice and relaxing. I'm still havig a hard time understanding these adjustments in a basic since.

As Gladius mentioned, the 450 isn't a backyard flier, unless you have a HUGE backyard. I tried you approach and it just doesn't work. You won't get the learning experience needed to fly this heli well! You need to think of the safety factor here also! If you can continue to fly at your Dads, do it! You won't regret it!
Watch Finless Bob's Helifreak tech room, heli skills and setup 101, pitch and throttle curves 101. It will help you to understand these values! |

Here's my 450 flown in my yard. This was the first flight after conversion from a 3D to an "X" consequently the first 60 seconds is just hovering and settling the nerves. At 1:00 I start moving it around a bit.
Although I have 1.2 acres, a lot of it is taken up with stuff. Tall trees, a patio, pool, you get the idea. I have about 20 yards wide by 50 yards long to fly in unobstructed. https://www.youtube.com/watch?v=tPQO...ature=youtu.be DH

I've flown in less space but the more room the better. And higher is also better. More time to recover from dumb thumbs.

I bought a 180CFX which "seems" to give me more room (an illusion because that heli is FAST!) but of course is even more subject to the wind. There's no easy solution other than to stay low under the protection of the windbreak of the trees - which is minimized now that they've lost their leaves. I find myself flying the 180 at first light, then the 450's, then....most days I'm grounded by 15, 20, even up to 35mpg gusty winds. I do take my quadcopters out in the wind. They seem to handle it better and I can fly them down on the deck 1 - 3 feet in altitude with no problems. They're tough as nails by comparison to the Blade helis.

To quote Admiral Akbar... "IT'S A TRAP!"
That's a nice open area that just wants to seduce you to fly in... but the backdrop of trees will make seeing the heli difficult (especially so in low light conditions, like dawn). They WILL reach out and touch your heli (and not in a good way). And I can't tell where you're standing in your video, but from where the camera is, it looks like the sun is behind your heli, which will also cause orientation difficulties. I'd be so tempted to fly there too, but after a couple of , followed by -$$, I would avoid it for all but test hovers.

^^^Right on all accounts. I was flying at dawn (I think it was before work) to capitalize on the low wind conditions. In the afternoon the sun isn't so inconveniently placed. No matter where I stand in the yard there's going to be trees as at least a portion of the backdrop. I painted the horizontal and vertical stabs a nice fluorescent yellow. That helps a bit.
Come spring I'll get out to a proper flying field.

I'm not sure what your budget allows, but a 500 size heli handles the wind a lot better. But you definitely don't want to fly that in your backyard!

DH that actually looks about the size of my yard.
You're handling it well. If you aren't having much fun there don't be surprised. I don't have much fun with my 450 in the backyard either. With a few years experience I can fly it with more speed, but even with speed I just don't have fun with it. Anytime I want to practice new stuff, there just isn't enough space, and that's why I got the 180 which fits beautifully for me. I would recommend you find a better field so you can build a better relationship with that helicopter. Good luck on your hunt. I have found fields between tree lines or office buildings that protect from wind. The 450 can handle some wind but it doesn't make learning much fun, and strong wind gets old quick.

Here are my setups for really tame upright slow forward flights in my back yard. Using a B4503d and DX6i
Pitch - 50, 62,75,80,85 TH - 0, 25,55,68,75 Stunt mode the only change is the TH curve is 75,75,75,75,75 DR/Expo - aile 50% +25, Elev 40% +20, Rudd 40% +15 This is a good starting point. I find if I can fly everyday then I start taking some of the tameness out a few clicks at a time.

I will suggest a slightly different approach. After you get the slightest forward movement, make your right stick movement at around 5 o'clock rather than at 2 or 3 o'clock. |
