Hi,

On HH site they have 2 versions of the dx7 radio, one for helis and one for aircraft.

Does anyone know the difference between the two?

I was HOPING to get 1 radio that I could use for both heli's and planes!

either one will do both. the software is the same.

switch positions and whats in the box are different.

edit: the throttle is unracheted on the heli version

the main difference is the heli version comes with a smooth collective stick and all the models are preset on heli instead of airplanebut can be changed back to airplane in secconds

so would having a smooth col stick be bothersome on a plane?

Or the other way around, would the non-smooth col stick be bothersome for a heli?

Absolutely not, if anything it would make more sense for the 3D guys that hover. I'm still wondering why radio companies don't just make all of their radios with smooth throttle sticks.

Yeah, if you ever try flying a heli with a ratcheted throttle, you may find yourself hovering between clicks at times.

Get the heli version. I bought the heli version of the Futaba 9C Super and wound up liking flying airplanes with the non-ratcheted throttle. I like the feel a lot better.

Also keep in mind that the switches are in different locations. I would also suggest getting the heli version, if not your idle up switch will not be in the upper left corner but you would have to use the flap switch on the plane version.

ok looks like the heli version it is!

It gets expensive to have all the radio gear in each and every plane/heli eh? (servos and receiver)

As Al said, its better. Every planker thats flown my Funtana with the smooth throttle has had me convert thier throttle sticks.

I think the airplane version only has 1 idle up position on the switch.1 normal and 1 idle up.

I have the airplane version and the idle up switch is in the upper left and it has all three positions the only dirrerence in the heli version is the sticker below says idle up or somthing instead of flap.

I'm still wondering why radio companies don't just make all of their radios with smooth throttle sticks.
For planes, its nice to know a specific power setting for landings and using the method of how many clicks up from idle, gives the pilot a consistent way of setting the power setting for consistent approaches. Kinda like fullsize where we use the tach to tell us of the power setting, it makes landing much easier to do things the same way everytime, makes for consistency.

Nice theory but different wind conditions dictate different power settings so I just put it where it needs it.

It's not a 'theory' Yes, power needs to be varied constantly through the approach to make the TDZ, but starting at a constant power setting to establish the glide slope helps to get things more consistent. Even then in adverse conditions the power doesn't vary too much from the constant unless your just making a bad approach. But what do I know, I've only been flying rc planes for 14 years and a licensed faa pilot for 7 years.

No need to get testy or break out the credentials. I was just making an observation.

I agree with Hockey,no 2 landings will require the same throttle positions (per click).

Just wanted to add, that a headwind approach or tailwind approach will have the same approx indicated airspeed and approx power setting, the difference will be the glide slope angle. With a headwind, the glide slope angle will be greater than with tailwind. With the perfect glide slope to account for the actual groundspeed, the power setting(in a perfect world) would be exactly the same whether headwind or tailwind. Of course, not in a perfect world, it won't be in the exact same posistion, but it won't be too far off, like I said before. Man, I should really start studying this stuff so I know what I'm talking about.

Most people without real world flight training try to eyeball the same glide slope every time, its what they get familiar with seeing so they try to fly it every time. If theres more of a head wind they use more power.

Also we arent shooting ILS approaches with models, nor do we have any practical way to monitor IAS or course and GS during an approach.

(I'm a bit rusty myself)

Ok, its a bit of topic (for that I'm sorry) but it was going this sort of way anyhow,

Why do plank flyers, or could planks be flown with a type of idle up setting i.e. in "Normal" everything is the same as it is set now and in idle up its exactly that, low stick could be set at a given rpm that is the lowest setting for for flight etc and the gear (if present) could be mixed in on this so its like a flying setting or set to a landing/take off setting??

Hope that makes sence to you all and if its nonsence, sorry, don't, haven't and probally never will fly a plank, so I don't really know much about them
