My DX7 on certain models will not activate the dual rate. Rudder for example. I set the low rate at 50% then flip the rudder switch and set it to 100%. When I return the switch to the low rate it is not 100% This is only on some models. Is there a mix someplace that I am missing. Called Horizon Hobby but no return call yet.

Not sure what you mean.

You say you "set the low at 50%, then flip the switch and set the high at 100%. When you flip back to low it's not at 100%."

It won't be 100%. Low will be 50%. ??

I don't remember which model Tx it was, but I had a JR that was somewhat similar until I went in and reset the model settings for that specific model. I went through and wrote down all the settings that took before hand so I didn't have to reinvent the wheel to make it normal again. Once reset to defaults, I was successful in setting all my settings to where I was trying to take them. It appears that occasionally, the memory for a specific model slot takes a kind of scrambled bit pattern, and the only way to fix it is to do a reset on it. It makes you more proficient at flipping the switches and setting all the settings by having to do it more than once...

Glad I'm not the only one that read it that way

goirish

the word should have been "now" instead of "not"

opjose

I would perform the model reset indicated...

You MAY have to exit the setting before you flip the switch so that it will "take".

SeamusG

To test your setting use the "servo monitor" function.

Got it. It was a menu item that I had never used before. BTW, Odd that Horizon Hobby never returned my call. Not like them.

Amazing how one little letter in a whole sentence has a completely different meaning.

Glad you figured it out.

goirish

Boy!! it did change the meaning didn't it. I was once told, "the hardest thing in the world to do, is get a thought from one person's mind to another in the manner it which it was intended"

SeamusG

Made so much more difficult when you cannot see their face (smile, frown, impartial, etc.).

stupid question, but are you sure you have the low rate set to the same switch as the high rate?

goirish

Yea, on the DX7 you have three switches, one for elev, kone for rudder and one for aileron. When you set the high rate (say aileron) then flip the switch you can set the low rate. Then go to another switch like the rudder and do the same thing.. There was a place in the menu that you could designate only rudder or aileron or elevator. The menu also allowed you to select all three. When I was having problems trying to do the dual rate. the menu was set only to aileron. Does this make any sense?

gjesion

Makes sense. The DX7 is set up to allow either one switch to set hi/low rates on all three surfaces, or to control them individually. A good thing IMO.

Didn't know that until I started playing around with the menu.  I guess if all else fails, follow instructions.

SeamusG

On my DX7 I use a single switch (common) to control dual rates for all controls - the aileron D/R switch. I use the rudder D/R switch for my throttle kill mix.

goirish

Hummmm!!! didn't know you could do that. I like the idea of the throttle kill switch. I just use the throttle recovery now to shut down the nitro engine. I use a servo operated choke for my gassers and that is how I just shut them down.

SeamusG

I would guess that you could use the same switch to activate the glow kill switch & the gas choke servo so that the flight line procedure would be exactly the same for all models.

The DX7 has a system menu (plane name stuff) and a function menu (D/R, mixing, all the good stuff). I think that you specify the common D/R at the system level. Check the manual.

DenverJayhawk

unless you really need rates setup on different switches, i would recommend putting all your surface's dual/triple rates onto one switch. It's much easier

opjose

When maidening a plane, I prefer to keep the rate switches separate.

That way I can test each surface individually to obtain the best settings.

e.g. You may find the ailerons do not have enough travel, while the elevator is far too pitchy, etc.

goirish

That is the way I like my set up to be.  Some times when I want to do a stall turn, I flip the switch for the rudder.  When I am on the ground taxiing I want the rudder on low rate.

DenverJayhawk

for me, when flying i forget which switch is assigned to which surface. So i set everything up on one switch. In reality, i probably don't need any dual or triple rate switches since i prefer to fly with high rates only.

carlospkf

I find the single switch method to work best. Also, it is a good idea to remember which switch you assigned. I spent an afternoon wondering why my P47 would roll so slowly even in high rates only to find that I was flipping the wrong switch in the transmitter.

goirish

I don't believe that I have that problem as all of my planes are set up the same way. right hand side switch=rudder, right hand front switch=aileron and left hand front switch=elevator. All low rates are switches towards me, high rate is switches towards the plane
