I'm considering a JR 9303 and currently have an 8103 (air model). Fact is, I don't have any idea what the difference is between the different types of transmitters. Both of these transmitters are capable of all three modes but they also sell transmitters specifically for each mode.

So, what's the difference?

The programming and functions of the switches. Also, plane radios have a ratcheting throttle gimbal.

I believe that the ratcheting action of the throttle stick can be adjusted out. And aren't all of the same programming functions available on each model?

Horizon, if I'm correct, lists the 9303 heli model at $50 more than the air model. If I got the air model, what heli capabilities would I lose?

Yes, exactly. I think the radios have different servos though. Another thing I thought of is switches are in different spots. Like with Futaba the air version has a 2 way switch where the 3 way would be on the heli version.

Switches are relocated and labeled differently for each version. The Heli version has smooth throttle stick action; the other two are ratcheted. (You cannot 'adjust' the ratchet tension to make it smooth, but you can manipulate it to make it smoothER.)

The air and sailplane versions have a programmable pushbutton switch in the place of the heli version's 3-position flight mode switch. The pushbutton is not available on the heli version TX. The default programming uses the pushbutton as the 'snap roll' switch, but many other functions can be assigned to the pushbutton.

Software is the same through all three versions, but each will default to the TX type when setting up a new model. For instance, the Heli version defaults to a heli when you call up a new model; the Air version defaults to the airplane software when a new model is selected.

Horizon has the 9303 w/4 DS811 servos and 1100ma RX pack for the same price in heli and air configurations.

They also have an 'advanced' heli version w/ 4 DS8311 servos for about $100 more.

Oh yeah - what heli capabilities would you lose if you got the air version? None, really. You would lose the convenience of proper switch labeling and the 'necessity' of a smooth throttle stick.

I call the smooth throttle stick a necessity because the heli NEVER wants to hover with the throttle exactly in a ratchet notch. It seems like it always needs to be in between notches. One notch up and it climbs; one notch down and it sinks. Have you not noticed this on your air version 8103?

Usually the design of the pressure bar is such that it can be inverted for Heli ( smooth ) or Aero ( dimpled ).

When you get the opportunity, take a look and see if that is the case.

Well, I would have to have completed my Venture and have it in the air before I could notice. I'm not even that "advanced!" I spent the summer flying fixed wing with the Venture ignored in my basement. _Now_ that cold, wet weather is here, is, of course, when I get fired up about getting it in the air!

Mac_Man,

That's exactly what I did with my 8103(Air). My 9303 is the Heli version (smooth ratchet), so I don't know if the 9303(Air) version can be done the same way.


Sabre,

Either version will work fine. Personally, I find that its much easier to fly an airplane with a heli-layout TX than a heli with an airplane-layout TX. The only real downside to the Air TX is the ratchet, and as Mac_Man suggests, it can probably be modified.

Thanks, guys. Just needed a good excuse to place my order for the 9303!
