I am doing headstands in a bucket of icewater! Will somebody please inform me about the 3/4 stick hover? Thanks!

I started off with 1/2 and have since moved to 3/4. 3/4 is where you need to be if you want to to do 3D stuff, it makes it alot easier with a V curve and inverted flying.

If you keep doing the same thing…...you’re going to get the same results!

I actually prefer both. In normal mode I hover at 1/2 stick, and in idle up 2 (where I have a v-curve on the throttle and a straight pitch curve) I hover at 3/4 stick.

In reality you'll barely notice at which stick position you hover. Your brain works in closed-loop to regulate the heli, and you'll just move the stick to get the output you want.

oyvindk,
Have you read any of the posts from guys that crunched when they accidently switched to idle up from a low hover? If you hardly notice the difference, why not make it simple and keep all the pitch curves the same? That's what I do.

Yes, I am aware of this problem, but personally I always switch while raising the collective. I don't find this to be a real problem, but I can certainly understand those who do.

I use 1/2 stick in normal for the increased resolution and for old habits' sake.

hover
at what hight should the heli be when hoving at 1/2 stick, i have just managed to get up about 2 in,s at 1/2 stick, as i am still learning on my venture 30 cp any tips on set-up for this bird with a jr 2610 radio,,,,

blackbird i don't think you have quite got the concept yet. the stick at 1/2 in this instance is the ammount of power and collective needed to keep the heli at the desired altitude(6 feet,6 inches or 600 feet). to go up move stick up then back to 1/2 to hold it there, and reduce the stick to come down and up to 1/2 to keep it there. Hope this helps.

The older i get the faster i was

Hover @1/2
I am self taught and Ray's Authoritative Helicopter Manual gives many reasons for hovering at 3/4. I have a Futaba 9CHP and I prefer hovering at 1/2 stick because I can "skew" the throttle and pitch curves with VR (A) and VR (C)! It really comes down to personal preference.

3/4 stick to start with.
Butch

I have only started flying since the beginning of the year,
But from day one was setup to use 3/4 stick.

So I would not have to learn stick position at half stick
then change to 3/4 stick to hover.

Also I will not get confused when using idle up.

I can switch to idle up 1 or 2 just about half stick and the heli does not change in any way.

So far so good passed a BMFA A test with Paul heckles and well on the way working on B.

Cheers Rob

There is an argument to be made both ways. On the one hand having 3 exactly similar curves eliminates any drop in hover when switching flight modes. On the other, in hovering mode (Normal) -9 or -10 is completely unnecessary- therefore you lose the precision of having the entire stick window control control pitch from lets say -2 to +9.

For F3C hovering is critical, and I would venture to guess most FAI pilots (not all) hover at 1/2 stick in normal. The switch to idle1 is made while climbing out and is therefore almost unnoticable. Idle 1 and idle 2 are usually the same pitch curve (-9/+9 or -10/+10 etc.) with the throttle curve (and/or governor settings) being different (i.e. higher head speed in idle2). The change from idle1 to normal is correspondingly made in the descent and again almost unnoticed. Set up this way Normal controls a 12 degree useable pitch window- from minus 2 to +9 with the half stick position being around 4.5 to 5 degrees= precise hovering.

For 3D flight (very little hovering other than inverted) normal is only used for takeoff and touchdown and therefore switching into idle1 immediately after takeoff is common. Switching into idle 1 on the ground (after spool up) or even a foot or two off the ground is not unusual either. Here having the same pitch curves eliminates the drop and allows for switching at will. Set up this way the pitch window controls 19 degrees of useable pitch with the half stick position being 0 degrees exactly. Linear throw- but not as precise.

There is really no "right" way- use whatever is good for you. The most important thing is to set up your entire pitch window correctly- mechanically. I usually do this with a linear curve in hold. Then you can fine tune the bottom, and take all you can get on top. If not exactly mechancially even, set it up for the extra on top (i.e. -12/ +13). Mechanically, set it up so that at center stick- everything from the servo to the blade is 90 and zero- servos exactly centered, all pushrod arms at 90 and blades and paddles at 0. Pitch compensator/washout at half travel and perfectly flat/parallel arms Then you can do whatever you want with your curves and change them at will, knowing the heli is mechanically correct.

Whichever way you decide to set up your heli- HAVE FUN!

3/4 stick started at 1/2 and I if I had it over to do again I would start at 3/4

So let me see if I understand this.

If you hover at 1/2 stick, the neutral on the heli will be setup with the pitch necassary to hover.

If you hover at 3/4 stick, the netral on the heli will be setup with 0 pitch.

I'd been under the impression that whether you did 1/2 or 3/4 stick the mechanical setup was the same. It sounds like my thinking was wrong.

36 degrees
After work yesterday, the wind was calm and I got the heli out and practiced some pirouettes. As I stated earlier, I hovered at half stick, and then went to 3/4 stick. Hovering was just as easy at 1/2 as it was at 3/4! I still like to warm up at half though and play with the GV-1, which I have set at 1600. Then I play with the hovering throttle knob and that tells me how much effect the density of the air has that day. Yesterday there was no change and that was the first time!
