Hear about lots of people switching from Spektrum to Futaba over in the futaba channel.

Anyone switch from futaba to spektrum? Why?

Ever notice how crash rhymes with cash?

Spektrum sucks. They really screwed the modeling public with the DX8 and the in suing recalls/service actions. They have the right ideas but quality is really lacking. Now they introduce a new radio the DX7S and manufacture it in the same case as the DX8. People may confuse the new radio with the crappy DX8 and not buy it. Poor poor marketing, but they deserve what they get.

How about JR? Using spektrum technology, and the radios look similar to me. Deciding between X9503 and 8FG.

Here is my take. The recalls are unfortunate but they are taking care of it. My DX8 has been great so far and having telemetry is very useful. Just check your equipment and make sure there are no issues. Any product can have a fault or defect. We have lost astronauts to O rings for crying out loud. A million dollar Lamborghini can blow a gasket. Personally, I am starting to think some radio company's are getting nervous with the features and price that spectrum provides. Just check your stuff and check It often. Use a check list if you have too. Also, if you are sending up an expensive bird. Put the most expensive RX you can get on board. This is a key factor after all. I don't know why you see guys sending up $3000 + helis with cheap RX's they buy second hand from a guy who got it from a guy who crashed it before.

I've never met a helicopter I didn't like :)

To some extent I agree with Adam. But Spektrum should not have rushed the DX8 to market until it was proven backward compatible with it's own receivers. I also agree that you should put the most expensive receiver you can afford in your expensive aircraft. As to JR using Spektum technology that is true, but JR is a whole different radio. And I feel the JRX9503 is far superior to the DX8. Spektrum had an opportunity to set the transmitter world on it's heals but they blew it. They brought to market a feature filled, unproven radio. The features are what got me to buy it in the first place. I'm truly satisfied with my new 9503 but I had to give up some features that I had with the DX8, but I did that for the secure feeling that a quality radio gives you when flying.

No argument there either. Spektrum did bring the DX8 to buyers hands too soon it seems. I'm going very cautiously with my DX8 and will continue to do so until I can afford something better. I'm really liking my DSMX with on screen data logging though. It's nice to know I have signal strength data available to me.

All that said. I'm coming from a JR 10X that has been rock solid for ten years. I want a radio that is up to date with all the new features that feels more like the 10X. I would like them to go a step farther and start using hall sensors in servos and TX gimbals. Whoever comes out with a high end radio first JR or Spektrum will ge my purchase. I want lots of channels at least 12, hall sensors, a nice screen and no skimping on components.

That's my wish list for Christmas. Doubt it will be this year.

Hi

How do you go cautious with a radio?

It either crashes helis or it doesn't..... I am vey happy with my DX7 to 8FG switch.

I liked my DX7SE, was an awesome radio for my heli needs... small, versatile and more than enough functionality to fly a heli... the DX8 was an awesome upgrade for me, does so much more... I bought one out of the second batch to come to SA... no alarms or any problems encountered so far... if only it was as small and nice to grab as my DX7SE... that's the only thing I don't like, bulky...

Pwood, I am cautious by checking my pots/gimbals and doing range checks.

In the case of either crashes or not, mine is not. I'm sure there are a few DX8 owners out there that have used it as an excuse too. I mean no disrespect to those that have lost a machine legitimately to the dx8.

Is the 7SE smaller? I have huge hands so I'm really liking the size and grip of the dX8. I do however think it feels light and cheap compared to a nice JR radio.

I upgraded from a 6ch Futaba to a DX8 for a few reasons; mainly my futaba developed a few nasty glitches. Love my DX8, telemetry is handy, in built charger is great as are all the rest of the features,not to mention the price. Havent had a single issue with mine so far.

It doesn't appear as though Hall effect encoders are ready for prime time. I have been waiting for something to replace pots since 1967. Better pots are probably all that you should expect.

Rule of Thumb:

A pot advertised for 1 million cycles will last 100 hours in a transmitter flying helicopters.

There are precision instrument pots rated for 10~50M cycles.

Four Stroker - where does your rule of thumb come from? I've never heard that before, did I just miss that?

So a Tx is only good for 100hrs? Seems a bit low!

I had the issue with the AR6200 and got really lucky that it locked out when I was high and came back in time to get it back on the ground safely. This really ticked me off, but hopefully this update will fix all the problems? I had really good luck and no problems for a quite awhile even using the questionable receivers.

I thought about going to the 8FG, but I've got way too many Spektrum receivers and it'd be cost prohibitive to convert everything over, that was the main reason I didn't. I used to love Futaba and still love their quality, but they were too late to the game in spread spectrum.

This hobby is like Kryptonite to chicks!

went 12FG to 9303 to 12X.
Like the JR ergos better, and access to receivers like the AR7100 and all of the BnF stuff.
12x is hand down the best feeling transmitter for my big hands, flying pinch. I could not fit my ring fingers between the top switches on the Futaba stuff, and hated the plastic case.

I flew Futaba 9CHPS, then a 9ZHPWC2, then 12FG, so I am acquainted with Futaba.

You will get plenty of Internet Electrical Engineers talk about RF stuff, but simple fact is DSM2 worked well, and DSMX fixes any issues. For modern helis running mostly FBL, the programing is really irrelevant. It comes down to radio feel and types or stuff you want to fly

Pot ratings are like tire ratings. TX's should use conductive plastic pots since a TX is a benign environment.
