With electrics (big electrics at least) it's almost impossible to predict the maximum safe flight time because the batteries give good power even though they are almost empty

its easy, just fly 3 min and recharge. Divide the mah put back by 3 to get mah per min used. Muliply your pack capacity by .8 to get the maximum capacity you can use per flight. Divide that number by the mah per flight you use to get your flight time. You would still have to do this to plug the info into the transmitter anyway.

My Posts This: Topic  Forum		I know how it can be calculated, but the fligh time can vary you know. It can be 2.5 min or 4.5 min depending on the flying style. I don't fancy flying always 2.5 min just to be sure not to deep discharge the battery.

I think it would be much easier to just set a desired mAh number into the transmitter and get all the safe flying time out of the packs.

Sounds good but I don't think the technology is available to do what you are asking.

That's why we calculate based on our personal real time usage.

It would be great if a battery could be measured and the unit would continually provide the exact stop fly in real time.

It is available, Eagle Tree has a Wireless Pro unit:

"measure power consumption with a small ring that is placed over one of your battery wires."
"this unit sends the data from the Recorder to the Dashboard"

Check it out:
http://www.eagletreesystems.com/Plane/plane.html

It can't be too hard to design a receiver with built in logger and add a receiver and a "mAh timer" menu to the radio?

I heard Multiplex will soon have this kind of radio available, I hope Spektrum/JR will do the same soon.

My Posts This: Topic  Forum		The wattage the receiver bus bar can handle

How about the specs for what the receiver power bus will take. That would be useful info or at least good to know.
Have it displayed like an ESC: Continuous and Maximum.

My Posts This: Topic  Forum		Servo Wires

Servos have benefited from a great many improvements, but not their connecting wires. They all still have the same cheap insulation that has been used for years. A factory upgrade to a more wear resistant insulation style could be accomplished without significantly raising the cost of the product. Spiral wrap and woven mesh protective measures both lack flexibility and are of questionable help. Do it right - at the factory.

My Posts This: Topic  Forum		Telemetry

I want in particular, my heli AR7100R/DX7 to work with telemetry. With the available sensors, you could monitor engine temp, and set alarms, monitor battery voltage, and set alarms, & monitor headspeed/engine RPM. Think how this could help with throttle curve setting, mixture adjustments, and avoiding low battery failures.

Ideally, I think telemetry should be available with all RX's & TX's, let us decide how to use it.

11X transmitter to US by next March/April
ball bearing gimbels like 12x
12x features like e cyclic ring, gyro menu - T lock option I like that, 3 position switches, most important IMO 11ms latency. Also, adding better swash tuning options like Airtronics/futaba. Throttle trim assignable to those otherwise useless side levers(at least to me) WHILE in TH ONLY). Ability to flash updates via USB/Firmware or at least send in to Horizon for them to update if the process is prone to nuking the eprom and it's to "dangerous/risky" to let average guys do it. I find that in todays climate of technological advances etc... We have a "stagnant" tech radio once it's bought. No real updates available at least from JR. I think Airtronics with their new 10Ch Tx has that future option. Plus alot of other cool heli features that leave my 12x in the dust. The only thing keeping me with my JR now, is I've had great/awesome service from Horizon, and I love the AR7100 rx's. That said Airtronics service has been good for me too, and if they come out with an Rx that has similar features as the AR7100 I'll be very very tempted to switch due to the cost/latency benefit.

IMO the 9303 is becoming dated. At $600 give or take for the Tx it's surpassed by the Airtronics and Futaba 10ch's at better price points too IMO, with features just dwarfing the JR. I'm not trying to slam JR here, I fly a 12x, and have a 9303 and love them. However, I gotta point out the shortcomings as well, as if JR/Horizon/Spektrum doesn't continue to push the envelope they will end up on the hind end eventually. My 12x added some nice features over my x9303, and the feel is better, but TBH it's not worth the price of admission, at least for ME. It's a very feature rich radio for sure with tons of capability and I'm sure if I was a giant scale plank flier, or a pro I might think it's worth more, but I fly just as well with my 9303 vs my 12x.

The 11x gives JR and hopefully if imported, Horizon the chance to makeup some lost ground on the competition. I really feel we as consumers WANT and possibly "need" 11ms latency. We should have the best of user programming like Airtonics and Futaba offer. I mean really, the 12x has limited switch assignments. It doesn't keep me up at night, but it's irritating my friends cheap futaba radio does and my $1500 12x doesn't. Backlight I think is mandatory for the 11x. The screen looks good otherwise. IMO the 12x update whenever that is needs a color LCD ala the 14ch Futaba. LCD's are cheap enough now that it's just lazyiness on the manufacturers for not including that. Also the 14ch Futaba you can take a small pic of your plane/heli and put that on the splashscreen of the model you're flying. Nice option.

Also while I'm wishing.
9ch Heli Rx like teh AR7100. I guess I don't need it, but some other guys might use that. I had a switch n glo I wasn't sure how to hook it up so I just sold it. Yeah maybe I could have got it working, but I was lazy and just went the easy route of a remote glow. I guess a guy could use the 9ch powersafe and then run a regulator for the gyro, but that's just addtional wiring and space hassles

Titanium gears for the JR servos. Why can Aligns $60 servos have them and JR's $130 not? Also brushless servos. I love the Futaba BLS451's in my helis and maybe it's just in my mind, but they just seem so smooth compared to other servos I've used ie 8717, Align, Hitech etc...

thx for listening even if you roll your eyes and flag my account as a pest heeh

My Posts This: Topic  Forum		Non-volatile model memory storage

I'd like to see Model Memory info stored to a SDHC media card for unlimited number of models, that can be removed and put right into another TX without need for any trim adjustments. All without the need to hook the TX up to a computer, just swap memory cards and go.

That's a great idea and not hard to do at all.

Most of the TX stuff I have had for years with my Futaba 12Z. That confuses me about JR as to why they don't stay ahead with full features.

My Posts This: Topic  Forum		Everyone screams telemetry, but be honest with yourself. Once you setup your system, use a data logger and know what you need why would you need it after?? For AP work where GPS shinto is in effect I see the point but for all other tuning appys it seems it would be used very little and I'd rather the money was into quad bearinged gimbals and better quality switches and assignments. It ticks me off to no end there is not a high end DX7 version or something, 7 channels is all I need but give me a nice case and some good quality gimbals and pots for crying out loud!!!

This is a crazy statement, and here is why. 1)It's available...

http://www.helidirect.com/seagull-w...sion-p-2015.hdx

2)$369 is a lot of money for something that no one wants.
3)It's out of stock, so someone bought them.
4)It's available on surface TX/RX's.

Why wouldn't you want ACTIVE MONITORINGof your engine temp, that has nothing to do with initial setup. Why wouldn't you want ACTIVE MONITORING of you battery voltage, that has nothing to do with initial setup. Why wouldn't you want ACTIVE MONITORING of your headspeed, while it has something to do with initial setup, the idea that you wouldn't ever want to change these settings LIVE is crazy.

The thing you naysayers are missing is that the technology is already incorporated in the platform and the cost of putting it into the DX7 as opposed to the dx3s, or the 3300T as opposed to the 7100R, can't be much. We're not asking for something new, just that it be applied to the entire product line.


PS - if EVERYONE is screaming for it maybe you're missing something.

Offering minor changes in new radios promotes upgrade fever. Offering all the upgrades with one radio that does it all may encourage "A" one time upgrade, but then there would be no point in buying radio after radio after radio.

For example, Alan Szabo was flying the DX-7SE all along but Spektrum/JR decided to market the DX-7 at reduced performance levels until sales dropped off. Once sales declined they announced this "new" magical version of the DX-7 SE with super fast latency numbers, just what Alan was flying all along (secretly). Now, everyone who had to have the latest and greatest bought TWO radios instead of one. Had the SE version been available all along Spektrum would have lost out on the second rush of sales.

Basically, its called "keeping a carrot in front of the horses mouth".

Can you say, "Marketing".

With the new competing radios available to consumers now the marketing strategies will have to shift. Competitors are offering user upgradable software, customization, etc. that JR has historically been reluctant to implement. JR consumers are starting to realize this gap. So are the JR engineers and marketing staff.
