Hi all,

I just installed the Heli3 software card in my Stylus and now I find that the triple rates for the aileron, elevator, and rudder are gone and cannot even be assigned to a switch. The only option for rates is to assign a percentage of throw to each flight mode (i.e. normal, idle up, etc...). Also, the rate switch for gyro gain is gone and can only be pre-assigned for each flight mode as well. Why would something so basic as switchable rates be removed from UPGRADE software? So now I have four switches across the face of the transmitter just staring at me doing nothing at all. Any Stylus gurus know a way to cheat those rates back onto a switch somehow or am I stuck without my triple rates from now on?

Ever since I learned to fly planks many years ago, I've been used to having rate switches at my finger tips and I really don't want to give them up now.

I can't help you much with the Dual Rate issue. When I was learning to fly, I had a couple of DR related mishaps so I learned to use a combo of expo and ATV to get the feel I want. Now that I am into competition flying, I find myself wanting less throw for the hovering manuvers as compared to the flight manuvers so I have been playing with the flight mode based DR adjustment and really like it as it allows me to use the function without adding any switches to worry about.

You have 5 flight modes (4 flying, 1hold) to work with, 15 (12 flying, 3 hold) if you use the alternate aircraft function, so you should be able to devise a workaround.

About the Gyro gain, the heli3 card allows you to switch between two different gains in each flight mode so I don't understand why your saying you've lost functionality in this respect.

I use the gyro sensitivity switch at positions 11 and 12. One thing you have to remember is that now you will have to go in and set BOTH gains for EACH flight mode or you will get the default settings.

Thanks Mike,

Yeah, I don't know how I overlooked the dual gyro setting. I must have missed the gyro section in the supplement where it describes how to activate the gyro2 in the SW menu. I even read the manual cover to cover before I attempted any programming at all.

Oh, I did some messing around with it today and I was able to program switchable rates from any flight mode. First off, I set the D/R the same for each flight mode for aileron, elevator, and rudder at my preferred low rate. Then using C-Mixes and assigning each of them to a switch, I got my high rates. For example, I set the D/R for aileron for ALL fllight modes at 65%. Then on C-Mix(1) I set master to Ai1 and slave to Ai with a 35% mix. I assigned that C-Mix to switch 14. So now I get 100% throw with that switch down turning on the mix. Just like the dual rates I'm used to! Works perfectly in all flight modes. I duplicated the program for elevator and then made two mixes for rudder on switch positions 9 and 10. Now I'm perfectly happy with this Heli3 card. And even after using 4 C-Mixes for my rates, I still have 5 mixes left! Nice.

Now back to getting my Fury built!

Sounds good Keith,
A couple of things to remember though.

1) Remember that you are mixing a primary flight control into a primary flight control so you'll want to retain any trims or offsets or such. You may have to use the Ai2, or 3 menu selections for example. These allow you to tranfer any changes, that affect the master channel, to the slave channel.

For the Fury, You will definitely want to use a pitch-to-ail and a pitch-to-ele mix to work out any interactions at full and low pitch. If you do your linkages correctly, you'll only need 2-3% mixing. These will need to be always on. Double check that these mixes, or your "DR mix", wont be messed up or lost when you flip the "DR mix" switch.

If you find you have too much overall throw, use the CP-EPA in the CCPM menu to set your max throw, NOT the regular ATVs. I ended up with about 60% on all three channels but I found any more than 80% will bind the swash plate against the pitch slider anti-rotation pins at full throw. Leave them all the same and avoid using them to make up for any interactions. If you find the swash is not level at full and low stick, use the pitch-to-cyclic mixes I told you about above.

2) Also remember that with mixes it is possible to overdrive the servo. For example, in a 3D cyclic-to-throttle mix, it is possible to overdrive the throttle servo when at full throttle, then giving a cyclic command. With the heli3 card you can set a hard limit on any servo with a the SV-LIMIT menu. If you get several mixes acting on the same servo you may find you'll need to use this function.

Have fun,
Mike

Ahhh, yes. You've given me some good things to look into. I hadn't thought about what my mixes would do in a CCPM situation. I was getting my Raptor programmed when I came up with the D/R mix idea so it wasn't a concern for that ship.

As far as using Ai2 or 3, the trims, offsets, and delays are already on the channel once and flipping the mix on would double the trim, offset, etc. That's why I chose Ai1. The channel is already trimmed so I just want the extra percentage of stick throw added on. But are you seeing something I am overlooking?

Thanks,
Keith

Probably not. It was late and I was mainly trying to get the idea across to always be looking at the overall picture. "If I do this, what will happen elsewhere???"

Its really easy to start ganging mixes that will get you into problems if your not thinking things through which it sounds like you are.
