Did some searching and just couldn't figure out if statements like "2048 resolution with 12 channel receivers" meant you wouldn't get it with 9 channel receivers on at least some of the channels.

Thanks,

IIRC the 921 is basically equivalent to the AR9000.It should bind @ 2048.Try it.Watch the bind screen on the Tx closely and see what parameters it is binding at.

For what it's worth, which isn't much since it doesn't work properly, I tried it on an XP machine. Would not run at all until I installed .NET 4.0.

Then when I tried to edit a file it gave an error; "Editing is only allowed on DX8 profiles at this time." I did not get that error on the W7 machine but the file corrupted somehow and would not import into the radio.

Fine for viewing files on either W7 or XP. Both seem to have the same version of .net

Upgrading...need advice


I'm looking to upgrade from my DX7 and looking at the DX8, DX18 and DX18QQ. I'm building a AW 30cc Freestyle Extra 260 that I'll be using the new TX with. The 30cc AW Extra is my largest plane to date and I have five other electric planes I would be using the TX with and a few heli's. I have no intentions in going any larger than a 30cc plane due to transportation limitations and storage but the 50cc and 100cc planes have caught my eye. Could see myself building a scale H9 1/4 scale PA-18 or warbird after I finish my Extra. Only concerns going with the DX18 or DX18QQ now is not really using all the functions of the radio with my current planes and by the time I would need the additional features there might be something new out or a newer technology. Any advice would be greatly appreciated...Thanks!

Transmitter Upgrade


Always a personal decision, but I generally would rather be limited by my programming abilities and/or $$ than by TX limitations. For the size birds you describe, one could easily use eight channels (two for each aileron, two for the elevator halves, one for rudder, and one for throttle) - smack against the limit of a DX-8; a nice radio, but no growth possible.

I consider the DX-18 as having more powerful programming capabilities, more mixes available, etc.; i.e., you most likely would not outgrow the radio because HH listens to its customers and upgrades are highly likely, but, obviously, not promised or "leaked".

The feel of the -18 vis-a-vis the -8 seems to be something that owners of both like to point out - again, a nice plus for the -18.

You indicated that warbirds are a consideration and they can chew up channels quite quickly with flaps, retracts, canopy and/or airbrakes, etc. Take a look at the sequencer capabilities of the -18, read the excellent sequencer thread started by FreeChip, and you can see that there is room for growth; both you and the TX programming.

I used to own a DX-7, then a JR-12X, now a DX-18; the -18 is superior to the other two, IMHO.

You buy the best you can afford today to save money tomorrow if that makes sense to you.

It's not what you need, it's what you want in this hobby.

That said. The 8 felt better in my hands than the 7. The 18 even better.

I keep seeing posts where guys ask "what radio do I need" or some such question. I keep trying to tell people the above but some just don't listen... lol

Thanks everyone....great advice. I feel that the DX18 or DX18QQ would be my better long term radio...The DX8 would be great but I think within the next few years I would be looking for another TX.

Your killing me freechip......but the bottom line is we all know we are in this hobby because we love it....Someone from the outside could never rationalize what we spend on airframes, gear and radio equipment. If your going to do it...do it right. That usually goes for any hobby....
