Be Careful with Esprit backorder. When I was going to buy mine, I was attracted to the lower price, but they were on backorder. I don't know if they still are or how Esprit works, but I didn't want to take the chance of being on backorder for months as they took a large number of orders b/c of the lesser price. I apologize to Esprit if they are no longer on backorder.

Re: The mAh rating of the charger that comes with the DX-7...Danny Snyder on the JR manufacturer's forum has stated that the manual is wrong, that it's a 50 mAh charger and is fine for the Rx and Tx.

Re: Esprit...Other posts here have pointed out that the Esprit lower price is due to the fact that there's nothing but a Tx and Rx - no servos, etc. - so it's probebly not as good a deal as some think.

Hmmm - just measured the Tx rate at 65 mA and the Rx rate at 60. Both batteries are fairly close to a full charge, so they are drawing less than they will when more deeply discharged. Then, the current would be higher, but not the 110 in the manual. Good catch!

Is anyone using a lipo for the transmitter yet? I had a 11.1V in my old JR, but I'm not sure if the new spektrum can handle a 11.1v?

I have a Duralite for my 9303. I plugged it into the DX-7 and it worked fine. I used that battery to program my radio. Seems great, but that is only my experience and have no word from Horizon as to whether or not it's recommended.

Good luck!

While programming my DX7 I acccumulated over 3 hours of running on the stock TX battery. Thats a tremenous increase over what the DX6 radio would do.

11.1 Volts should be okay. A freshly charged stock battery is very close to 11 volts when it comes off the charger. Mine stock right now is at 10.8 volts.

It has to handle 12.6V off a freshly charged LiPo pack and over 12V for a good while. It's a good idea to check with Horizon and make sure that it can safely handle it. Most likely it's a yes, but it will run things a little bit warmer and it's wise to ask.

This may have been covered as i have not read the whole thread but,

I have bought one to try (well 2 actually and 4 receivers) but I have a problem with the failsafe.

I am a big believer in failsafe being set to "bring" the model down within the aria it is being flown. normally i set wheels out flaps down, airbrake out ailerons up and motor idle. this way if you get interference (or get shot down) the aircraft will pretty much stop dead in the air and crash in a way that is within the flying area and at a speed that you could get out of the way of. this is mainly because I fly 45lb + jets and a jet that weighs that much on a 30 deg down slope will hit hard and fast even at idle and is more than capable of killing people.

I have just put the Spectrum in a Turbine Hawk and you set the failsafe at the binding stage. now if I set the switches on the TX for wheels out flaps down etc when binding, the only command it remembers is the low throttle (when switching the TX off) every other surface stays neutral

BUT if I just switch the RX on and not the TX it goes to the fail safe settings i set at Binding??

anyone else have this?

Normal operation. Throttle is the only control that actually will restore to the position it was in when THAT RX was "bound". All other surfaces, stated in instructions, and I've tested to be accurate, "hold last commanded position when the link is lost". When the TX comes BACK up, the servos will then go to whatever the TX has at that point.

Well, don't THAT stink![sm=punching.gif]
Sounds like a feature request for the 'Super DX' thread!

I just now finished setting up a Seagull Harrier 3D .90 w/Saito 100 with my new DX7, and found the same results[>:]
My Futaba 9C will store all control settings in PCM mode failsafe. I prefer my models to failsafe into a degrading circle.
Don't have to go xx miles to retrieve the remains[&o]

It is spelled out on pages 18 and 19 of the Instructions.

The boys Back

therefore if i faulsly set the sub trims and stick trims etc, then bind then return them to neutral i can "gain" an amount of failsafe?

onewasp

Worth a try.

FWIW,
Just completed four (4) more totally glitch free flights with my DX7 in the pictured Top Flite FW190D-9.
This plane feels more solid in the air than ANY others I have flown in the last 30 years and I can't attribute that to the plane and my building skills.

d_wheel

No. Only the throttle goes to the failsafe position when signal is lost. The control surfaces stay at the last position.

First flight with the DX7 in the waco. flew several times not one glitch, last time I flew this plane I got a hard radio hit and almost lost it.
Now have 3 more recievers to convert my gaint aeromaster, 33% extra and giant corsair, I have flown futaba for as long as I can remember and a tracker II for the past 3 years and will continue to use them on my smaller planes but for anything else it will be spektrum DX7 from now on.
I love this radio.

I have been flying my DX7 for weeks in a gasser...PT-19, and couldn't feel any difference between the new DX7 and my old Futaba 9CAP...however, today I flew the DX7 in my venerable old Kyosho Aurum...the poor mans pattern ship...and WOW...what a difference.
Now I can relate to what others have been saying about feeling much more connected to the plane with the DX7.
Is it real, or is it psycological....I dunno, but I like it...a lot!

Glad to hear it .

My experience is similar to yours ----- I have spent the last 5 years with a 10X and I have to admit that so far the DX7 has a better feel.

No, it doesn't have all the channels or options but ignoring the cost differences (which are extreme) I frankly prefer to fly the DX7.
---and I find that amazing.

I was looking at that setup with the A123's but they are a bit heavy, and my regulators are 1 ounce. It does look attractive to me to run twin A123's without reg's.. Do you know the exact weight of a 2 cell 2300 A123?

Flew my pattern plane's maiden today. AR7000 STUFFED inside this baby, it's .40 size. I have to turn the throws down, this darn thing is fast. WOW!!. the response is so quick, faster than me.

I have a few flights on my 1/3 scale now, it is perfect in performance per the radio. We tested the radio links active on the radio test range at Wright Patterson RAMS site, which is normally a hostile environment and nada!! Tailwheel broke off, but no big deal.

My buddy who owns one of the original TBM 35% extra260's, (foam rib) planes, just installed the ar7000, and was completely blown away at it's response. He pulled the receiver out of everything he owned, and went to the LHS and did some shopping!! Well known builder type, name witheld. His planes at Toledo will have 7000's accorrding to him. He's flying the 6100 in his BYP YAK tonight at the Dayton Bombers game. No more glitches inside the Gymnasium. I also heard the USAF has bought several DX7's for use in their small plane/heli development programs. They formerly used JR 72MHz.

I have ops tested the two switch mix method for killing or choking the motor in my previous post and it has merit. I am putting a small choke servo on my 1/3 tomorrow so to have an emergency kill capability since I run a digital servo on the motor and have no ignition kill switch other than the failsafe pin on the fuse and the throttle trim/mix.

Totally off subject for Dick HAnson: Thanks for the tips on the Super 80. That engine pulls the sukhoi to the moon better than the BME102. I couldn't be happier, once I learned how to start the thing.

I got one flight (finally) in a Showtime today with the DX7. Our field is co-located with the Solberg VOR/DME Navaid (SBJ). FYI, DME is transmitted between 962 to 1150 MHz and can have a peak output in the 1 kW range. Take a 2nd harmonic and you are in the 2 gHz range. Not on 2.4 gHz, but close enough to make you wonder how it will all turn out. We are literally next to the transmitter, with it directly to our backs about 150 feet behind the flight line. I took the Showtime out in a large rolling circle to the limit my vision, probably over a half mile with that size model and it was rock solid. Some non-radio issues prevented another flight, but everything was locked in and very responsive.

Hey Guys,

Just following the thread a bit and a question came to mind.

When you guys show up at the flying field with the spread spectrum systems, what is the reaction from the 72Mhz guys when you do not use any pins from the pin box? Do they worry? Do they seem apprehensive of flying when you are flying. Do they wait until you stop flying to go up? do they just fly as well? Are there a lot of nervous questions or what? I think there would be at some flying sites new to the spread spectrum radio concept.

Just curious, I have not seen anyone using them yet up here in the NorthEast.

Thanks

Good Luck with them...

No one seems bothered by it in either club I belong to. When the DX6 first came out, we had some meeting discussions in one of the clubs about the use of SS. We decided to use "foamy pins" so that SS flyers would stay in the habit of grabbing a pin. Not sure that gets applied all the time, but that was what we settled on and everyone seems good with it. A little education for members is helpful.

My club (In Sydney Australia) had banned 2.4 Ghz radios when they first appeared.

The national body (MAAA, equivalent to the AMA) has a policy that 2.4 Ghz was Ok but the club waited for some reason.

Now it seems they have had a change of heart and I can fly my Spektrum.

Everyone was interested to see it in use. I flew it high and far out with out any problems.

The Spektrum DX-7 rocks!! My friend "Airborne" send it up high.....range check Can you see the dot in the sky.
