Yes, the helios one works. I'm not sure if the pro version will be compatible or not. I'm using the Spektrum with the Mars R now.

Actually (this is a bit off topic) does anyone know if they are working on the spektrum for any of the JR Heli Transmitters? I've got a JR 9303 that I would really like to have setup for the Spektrum.

The Spektrum product is only for module based ground transmitters. Currently the only air DSM product available is for parkflyer aircraft only and it is not module based. I think the range is a problem in nitro and larger models.

What are you flying for a heli? I know a lot of people have used the DX6 in Micro heli's like the Blade CP, T-Rex, and others. With the Blade CP Pro coming soon too, I think the DX6 will be a popular option for that Heli too. I have one myself and have used it in my Tribute 3D. It's definatly different than a surface radio

And I am 99% sure Blake is right that the Helios Module works with the Mars, and the Pro Series will also work with the Mars, but I will double check for you.

it seems there is a bit of confusion on the spektrum. Does anyone kno whether the Ko Module can be used by both the Helios and Mars R or do they have their own seperate modules?

I have seen airborne spektrum radios for sale and the spektrum web site has an airplane shown under control of a spektrum.

Yeah, I know they have the DX6 and I've heard of people using them in the micro heli's. I'm flying the T-Rex (if that's what you want to call what I do with it.) I really don't want to give up the programming and stuff of my JR 9303. It's a great radio. It's similar I guess to the difference between an M11 and a Spektrum DX3.

I actually just switched from the Mars R to the M11 so I'm good to go.

Is the Pro version all new boards inside the receiver and module or just a software upgrade? If it is a software upgrade is it possible to send your old stuff back in for the upgrade?

I just got a Spectrum for my M8. I do not think it has the latest software update. I am using a GTB with it. When I turn on the unit the motor runs at full speed until the green LED comes the receiver comes on. Then the GTB acts normal.

How do I find out if mine has the update? Does anyone know how long it takes for the update?

You have your failsafe setup wrong, re-bind your receiver and make sure you put on full break when you are doing the failsafe....

Take care

I just bought a new receiver and it had a little green dot on the panel with the module part number. Does anyone know if that means it's the "latest" software? The receiver just came in to my LHS, so it can't be too old. Gary?

Hey thanks for the tip. It worked for me.

Now how about the update?

I have no idea how to tell if they require a software update other than to use them and send them in if you have any trouble with them shutting down. The module antenna routing is another story. They have a blurb on their website on how to check for that, but I believe it was more with the Futaba modules than Airtronics.

The last time I sent a few receivers in for the software update I got them turned in less than 10 days. The first time it was more like 3 weeks. I guess it just depends on how much help they have at Horizon.

Can anyone tell me which servo horn fits the spektrum servo Z590?

Futaba servo horn?

Hitec Servo horn?

JR servo horn?

KO servo horn?

Your transmitter should be the first thing you turn on and last to switch off. Doesn't matter if you have a spectrum or not.

At our club the other day I saw a off road car go completely out of control and flat out into a fence when the guy turned the transmitter off, with the car still on... The car broke in half
