›››› Hovering Pitch ratcheted lever? (https://rc.runryder.com/t816958p1/)
Posted by Mikerobe on 03-13-2017 01:36 AM:
I'm an Old-School pilot that uses the hovering pitch ratchet lever. Any one else left that hovers at half stick and uses the ratchet?

The lot I got is not a lot, but I thank God a lot for the lot I got!

I'm old school too but the first thing suggested was to get rid of the "ratcheting". Theory being that you would always be chasing that center .... one click up would be too much and one click less too little . The result would be the heli bobbing up and down and you trying to find that sweet spot for a steady hover .
Getting rid of the ratchet was the best thing I ever did to smooth things out when learning to hover .....I went to 0 degrees center stick when I started to learn inverted ....

Edit: in re-reading your post I think what you meant was to use one of the dials (pots/levers) to adjust hovering pitch/rpm to hover ??? No, I never used that feature. Guess I never needed it !

Been there, done that and old enough to know better.....

Half stick went away when 3D took off , 0 degrees at 1/2 gives you equal pitch positive and negative . You can hover at 1/2 but if you go inverted pitch will be off . The ratchet will cause you to chase hover so most get rid of it on helis . The knob I don't think is needed if you make sure your setup is mechanically correct .

I stole it ,flew it and gave it back ;)

yup

showing a preference will only get you into trouble, 90% of everything is crap...

With history in contest flying, I hover at half stick and do aeros with a mirror curve. I still like precision hovering set up, and there is no way to get super precise altitude control with the +/- 14D I use for lower RPM 3D. I use pitch channel delay for eliminate the jump or drop when switching in and out of hovering mode. Most of the F3C pilots here in the US do the same thing. Half stick for hover; mirror curve for aeros. I don't sweat little variances in hover point above or below half stick or chase them with hovering pitch trim, but I do have high and low pitch trim ganged on one knob to change the slope of the pitch curve as needed for varying wind conditions.

Stupid question here...lol

What's a "mirror curve"?

Simply means that the pitch curve above the zero pitch point is the same (but inverted) as the pitch curve below zero pitch point. Believe it or not, there are some of us, on some occasions, where the pitch curve is not a linear line between -100 - +100. For example it might be something like -95, -75, -40, -15, 0, +15, +40, +75, +95. A nice curve for a "flatter" feel around zero pitch.

Then I use a mirror curve.

Never heard it called that before....down heaa....lol

No-no-no-no! Read my post again, 'Ratcheted Hovering Pitch Lever', the little "ratcheted" lever on the left side of your transmitter that's used to manipulate/trim hovering pitch independent of the hovering collective stick position!
Stop hijacking my post with all your pitch curve theories!

I am old school and never liked the 0 in the middle unless in my aerobatic idle up curve.

I also never liked those ratchets, so I would INH them as I found that when I did not use a neck strap I would accidently activate them, one ratchet would be for slight increase in head speed and the other for pitch, on a windy day it was good to add a little extra rpm in the hover but I found when doing precision F3C over a flag to up the head speed and not pitch made the machine a little more twitchy, so in the end as I would only ever activate one instead of both I deactivated both including the rotary knobs.

Not sure what you're talking about

Transmitters were sold as Airplane or Helicopter type.
The Airplane type would have a ratchet on the throttle and
the Helicopter type would have NO ratchet on the throttle.

I must be the only one with this lever on my transmitter!

I haven't used them in years
but I understand what your talking about

I preferred the rotary knobs on the face of the TX
but I don't use them either anymore

lol

yep that's it mike.

it still depended on TX, mine was Futaba 10C and it came with the ratchet, all I had to do was undo the back and replace the metal strip which came in the box with the one without the little bend.

my old 9303 had the levers. First thing I did was disable them. I kept bumping them unintentionally.

Never used them on purpose. But, I started flying helis in '04. invert switch and all that had already been retired.

if it ain't broke, break it.

Posted by heliraptor10 on 03-28-2017 07:03 PM:
So that lever engages and disengages the notches?

No. The notches in your left stick are physical. You can take off the back of your TX and flip over the tab to the smooth side, if you like.

The side switches are just trims--no different really than the trim switches next to the pots. They're just supposedly in a better position for adjusting without adjusting your grip. I found I kept bumping them inadvertently so I turned them off. Now the side switches move but don't change anything in the radio.

if it ain't broke, break it.

I have that....never tried to use it....is that what it's for?

I was considering either a Futaba 8J or 10J but I see they no longer have the levers! This was definitely a feature I wanted and thus my reasoning for the OP. Kinda tuff to consider another brand as I've always owned Futaba!

The lot I got is not a lot, but I thank God a lot for the lot I got!

I setup as Dr.Ben explained earlier in the post for curves. To adjust I use the knobs on the face of the radio. I did try the ratchet on the side/back but I found it too easy to bump and would many times sit in a spot that bothered my hands. So I moved it to the knobs on the front.
Also the 14SG, 18SZ, and 18MZ have the ratchets you prefer still.

I still have the JR9303.. the levers are not "just trim switches", they are full fledged channel controllers. You could program and use them like any other channel controller.

I don't know why anyone would remove the ratchet from these channels. Too easy to move as is.

Hahaha most of the people posting are talking about the throttle/ collective stick and not the ratcheted trim levers that you were really referring to.

Anyway, to answer your question, I'm not using mine on my newer setup. I just inhibited the levers. I did use to have them active on my old 14MZ. One side was for hovering pitch, the other was hovering throttle. Was quite useful for fine tuning headspeed for F3C hovering specially when environmental conditions were variable. Additionaly, I had carburetor in flight mixture control on one of these levers then transferred hovering pitch and throttle to the two outer knobs on the front of the Tx.

No one was talking about removing any ratchets....???

Except for you, that is....
