Default Pitch curve on Blade 400?

I have been told that it is ideal if your heli starts to lift off into hover at about half stick.

With default settings on the Blade 400/DX6i, the pitch curve is 0 degrees at half throttle stick,
which means that you will lift off into hover at about 2/3 stick

Is there anyone that can tell me why this is done this way (and should I change it, once I get my 400?)

Thanks in advance

Peter

i changed mine to give a little more pitch earlier and it is a whole lot smoother taking off.if you try straight out of the box keep on your toes becouse it will lift fast when it decides to go.

They do that so when you fly inverted you have equal pitch between flying normal and upside down.

Psindrup,

I post this all the time, brushless motors should run at about 80 percent of there maximum RPM or more. The Blade 400 has a 420H brushless outrunner motor. Outrunners, run alot cooler than inrunners. Half stick should make the heli light, 2/3 stick seems about right if you're in normal mode. As skill levels increase, blade pitch and rpm's may differ. It's alot of trial and error. Be patient and don't crash.[8D]

Best of luck,

Dave / Choppersrule

peter -

The common set up for CCPM 3D helis is 0 pitch at mid stick or 50% throttle, in both Normal and Stunt Mode/Idle Up. From what I've experienced this makes for a seemless transition from Normal to Idle at mid stick. It also serves as a good neutral point to check the mechanical set up of the heli.


I've just put the pitch gauge to my B400 and here's the curves for the stock set up:

Pitch Curve:
Stick Position - 0 (Normal) - 1 (Stunt)
L - 35% (-3) - 0% (-10)
2 - 42.5% (-2) - 25% (-5)
3 - 50% (0) - 50% (0)
4 - 75% (+5) - 75% (+5)
H - 100% (+10) - 100% (+10)

Throttle Curve:
Stick Position - 0 (Normal) - 1 (Stunt)
L - 0% - 100%
2 - 25% - 92.5%
3 - 50% - 85%
4 - 75% - 92.5%
H - 100% - 100%


okay, so my columns didn't line up as I wanted in the post.... but here's page 30 and 31 from the Blade 400 Manual

Here is what I have been recommended elsewhere:
And it matches coppersrule's 80 rule better, where you have 80% throttle at half stick, where you start to lift off in normal mode.

normal throttle: 0-50-80-90-100
Idle-up throttle: 100-95-90-95-100

Normal pitch: 40-45-50-75-100
Idle-up pitch: 0-25-50-75-100

I think I will go for that.

Peter
