That is why I am switching.

Model Match

Lower Latency

No cable hanging off the back of the radio.

One thing the Spektrum needs is the ability to change TX Mode from the menus, or more to the point being able to support Mode III and Mode IV at all...

I foolishly bought a DX7 assuming you could swap the throttle ratchet and select Mode III in the menu (just like with Futaba radios) because I fly Mode III (a left-handed Mode II for those who don't know), but after some discussion with Horizon Hobby UK tech support it turns out they can't even set it to Mode III at the factory... they were very quick at dealing with my query though (just a shame they couldn't resolve it).

So I returned it to the shop and bought a Futaba 6EX 2.4GHz (although I'm waiting for the 2.4GHz 7C / FF7 to come out in the UK which should be very soon), which I am more than happy with. I will be sticking with Futaba from now on.

Futaba sets let you swap between all four modes, and the integrated 2.4GHz sets (ie 6EX/7C) have built-in Failsafe settings from the TX just like when using PCM, and the RXs are all just single units -- so these would be my three main things that Spektrum need to address.

Really happy with my dx7 till that nasty dx6i came out with most of the features I was missing from my Futaba days. I have been thinking about the DSX9 but to be honest if Spektrum brought out a DX7i I would probably go for that and donate my DX7 to my grandson.

P.s Mr Beard why don't you do a deal with Hitec to make you some of their excellent Karbonite gears as a replacement set/upgrade

I would like to see more emphasis on the fact that the RX goes into failsafe at any voltage lower than 4.8 volts!!! At least a big, red, WARNING! Do not operate with less than a 6v pack....ESPECIALLY when using digital servos! I'm sure quite a few people can relate their recent crashes to this issue. I was almost a victim but got lucky.

Forgive me if this has already been addressed, but searching through 12 pages of 9303 BS made my head spin.

It is 3.5v not 4.8

This is for the 9303 not the DX7

It may say 3.5, but mine goes to failsafe at 4.7! As metered on a Fluke multimeter through an open RX channel

I apologize, didn't know this was for the 9303 only.

That woon't catch any sort of servo load induced transient. Chances are you battery and/or switch harness are toast and the power is collapsing every time a servo runs. Second if a four cell nickel chemistry is reading 4.7 volts off load it has no usefull charge left in it.

Brand new JR heavy duty switch, and new Batt also. Cycled the switch 50 times like it says on Ron's website, and cycled the batt too.

I will never use the 1400MAH batt again, knowing what I know now. I figured it would work for 1-2 flights. There were no warnings on what size of batt to use for X amount of servos... That's my only point.

Helinerd - 1400 mAh does not define much, its the internal resistance of the battery that matters.

Here's a simple request....

...a transmitter antenna that isn't fragile.

Is there any reason the antenna needs to have that silly hinge on it?

I agree, since we are supposed to fly with the antenna sides parallel to the flying area (the end of the antenna not pointed at the aircraft) why not just mold the whole thing as an "L" to begin with? It could still swivel to fit in a case, but the hinge would be gone. This would also not allow the uninflormed to keep their antenna pointing straight out, which puts the aircraft in the weakest possible signal area at times. That being said, I have not had an issue with the stock antenna breaking on my DX7s or X9303, but I still ike the idea of locking the antenna in a "L" shape for just the reason of getting the best signal out to the aircraft.

I disagree - The movable antenna provides versatility - It can be bent pivoted or straightened depending on where/how it's stored/hung/packed/used etc - I'd rather it be removable flexable or non-protruding (like part of the case) so it never has to be dealt with at all rather than stuck in one position that might be fine for one person but not another

Movable, flexible is fine. I have no problem with that. A plastic hinge with a couple of easily broken pins is not my idea of rugged or long lived.

teamdavey2001 - I'm supprised your rx goes into failsafe at 4.7v. I've never had any problems running off a 4 cell NiMH pack although I do use hi current power cabling and connectors. If you're using standard JR/Futaba cables/connectors you could run into problems
Perhaps that's your problem ?

If you consider the radiation pattern, you get least sensitivity (half the range) with the antenna streight out. Agreed, I don't know why it was not moulded as an L to start with. Same with the X9303.

Yug, - my Rx does not go into failsafe at 4.8 volts - I missed the quotes from another thread. All mine are happy to below 3.5 volts.

I run low impedance 4 cell nimhs or carefully selected ESCs.

Since the transmitter is operating on the same band as 802.11b wireless routers how about providing the capability to use our 802.11 capable computers (ex. notebooks) to connect to the transmitter via a web interface. Give us the ability to configure, store and upload model configurations using a ordinary web browser software. Context sensive help would be very nice too.

If not wireless at least a usb connection.

Hi Guys

I would like the antenna to be removable. Like on my wireless compute modem. The Tx could then fit in regular Tx cases and the antenna would never get broken.

Regards
Paul

PS: This thread is getting real long, I hope 'my' removable antenna has not been mentioned before....

I love my DX7. The only things I would change are:

1) Add weight to the top of the TX
2) Make the timer countdown alarm louder.

My name is wannaflyguy and I approved this message!
