IntroductionThis manual !rovides a detailed overview of the ErSky9x o!en sour$e firmware used in the Turnigy9XR Pro transmitter. The "reat flexibility of this !ro"rammin" system means that there is a lot that

needs to be des$ribed. >ou mi"ht see this as intimidatin", but you don?t need to learn everythin"before you $an en@oy flyin" with this transmitter. That?s why we have !rovided a se!arate andsim!ler "uideA First Steps with ErSky9x . Be re$ommend you read that first to "et the overall !i$tureand to learn enou"h to "et you flyin". 6lso be sure to read Introduction to the Hardware seeC urther 'nformationD at the end of this manual3.

Be also re$ommend that you make use of the available 5 forums and es!e$ially!en 5forums.$om, whi$h is dedi$ated to the various o!en sour$e 5 firmwares in$ludin" this one.

There you will find enthusiasts, in$ludin" the !ro"ram and hardware develo!ers, ready to hel! you"et the most from this amaFin"ly advan$ed and still evolvin" 5 software. Bhile there, you should$onsider makin" a donation for their efforts.

The features of the 9XR Pro transmitter runnin" ErSky9x firmware in$ludeA +2 model memories !lusan unlimited number on your $om!uterG u! to 24 $hannel o!erationG !otential for telemetry$ommuni$ation and dis!lay on the s$reenG s!oken announ$ement of alarms, swit$h settin"s andtelemetry valuesG $om!letely free mixes allowin" almost unlimited !ro"rammin" of $ontrols andswit$hesG !oint and 9 !oint $ustom $urvesG assi"nment of any $hannel to any fun$tion. The radioalso su!!orts an # $ard for the stora"e of audio, firmware, telemetry lo"s and manuals to whi$hthis one belon"s. ErSky9x su!!orts )luetooth $ommuni$ation if the reHuired hardware is added tothe $ir$uit board. 't also !rovides I#) a$$ess to the $om!uter%based Eepskye !ro"ram, whi$hallows u!datin" the firmware, model memory and # $ard. Eepskye also simulates the sti$ks,sliders and swit$hes on the radio, both for !ro"rammin" and for develo!in" model settin"s. Easyu!datin" of the firmware allows you to benefit from the im!rovements $ontinually bein" develo!ed.

The $ombination of extremely flexible !ro"rammin" and a !owerful new main board desi"ned by #ky(orth results in an inex!ensive transmitter that is amon" the most $a!able available today.

Navigating in ErSky9x

Button NavigationThe transmitter has six in!ut keysA a $ru$iform set of '/ T ;E T I* B( keys, !lus $ontextualME(I and E:'T keys.

The '/ T ;E T I* B( keys to the left of the s$reen move the $ursor or !a"es in thea!!ro!riate dire$tions. (ote that short !resses and lon" !resses will !rodu$e different results.

or exam!le, when you turn your transmitter on it will start at one of five J omeJ !a"es. #hort!resses of the I* and B( keys will take you to different home !a"es. Ea$h !ress of the keybrin"s a new s$reen, eventually takin" you ba$k to where you started. Bhi$hever s$reen you lastused will be the home s$reen that a!!ears when you next swit$h the transmitter on.

'f, however, you !ress the I* key for about half a se$ond i.e., lon" I*3 you will be shown a s$reenwhi$h has information about the )attery and related matters see !a"e - 3.

Navigating Between Pages.The home !a"es form a $entral $ore from whi$h you $an "o ri"ht, left, u! or down to a$$ess sets of!a"es whi$h have similar fun$tions see dia"ram below3.

6 lon" ;E T !ress takes you to the adio #etu! se$tion where short !resses '/ T or ;E T allowyou to $y$le throu"h the 11 !a"es.

6 lon" '/ T !ress takes you to the 14 !a"es of the Model #etu! se$tion. 6 lon" I* !ress from thehome !a"es takes you to three #tatisti$s !a"es as you $an see in the dia"ram above. 6nd a lon"

B( !ress takes you dire$tly to the Telemetry !a"es.

The Telemetry !a"es $an also be a$$essed from the ome !a"es by short !resses of B( or I*a number of times until the first telemetry !a"e shows. These !a"es are re$o"niFable be$ause theydo not have the trim !osition "ra!hi$s alon" the bottom and ed"es of the s$reen.

6n ele$tri$ !owered "lider usually flies a lot faster when $limbin" than when "lidin". The extra s!eed"enerates more lift from the win"s, so the model wants to do a lar"e loo!. 6 little down elevator isreHuired to kee! the nose from liftin". Be need a mix to do this automati$ally.

6ssume the throttle is o!erated by a swit$h and therefore full !ower is a!!lied instantly. The /earswit$h /E63 is bein" used to $ontrol the motor and is on 5 , as shown belowA

Bhen the /E6 swit$h is fli!!ed to (, the si"nal to the E#5 via 5 "oes from %100 to N100be$ause that?s how the I;; in!ut worksA the value is either &wei"ht or Nwei"ht.

'n order to have this !ower%u! $ommand affe$t not only the motor via the E#5 but also the elevatorservo, we need the /E6 swit$h to $ontrol a mix in the Elevator servo $hannel 5 +3. )ut we onlywant a small effe$t, say wei"ht.

'n this menu, the first field asks for the sour$e of the mix. )e$ause we are usin" a swit$h and not asti$k we want the sour$e to be I;; or 6; . 6 swit$h has no intrinsi$ value unless a sour$e isassi"ned to it. Two !ossibilities are available for our !ur!oseA

Those are the standard mix elements. (ow for somethin" a little more so!histi$ated.

5onsider the behavior of the model when you a!!ly throttle. Even with the motor swit$hed to fullthrottle, the model will take time to a$$elerate and make the win"s "enerate mu$h extra lift. #o weneed to delay the a!!li$ation of lift $om!ensation down elevator3, let?s say by one se$ond. #o weenter 1 into the Jdelay u!J field.

the elevator $orre$tion "radually, therefore, we enter +. in the Jslow u!J field. The result is that whenthe throttle swit$h is a$tivated, the motor starts immediately, but the down elevator lift $om!ensationdoes not start for 1 se$ond, and then takes +. se$onds for full de!loyment.

(ow $onsider what ha!!ens at the to! of the $limb. The throttle swit$h instantly $uts the !ower. Themodel will be "oin" fast so down elevator is still reHuired to !revent the model from !it$hin"u!wards. Be need to delay the return of the elevator to Fero by let?s say 2 se$onds to allow themodel to slow down. Enter 2.0 in the Ldelay down? field. To avoid an abru!t $han"e in the air$raft?sattitude we $an also slow the elevator movement so it takes say 1 se$ond to return to neutral for the"lide. 'nsert 1.0 in the Jslow downJ field.

ere?s what the mix s$reen looks like with these $han"esA

Be now have a mix line in the elevator $hannel, usin" the throttle swit$h as the sour$e, whi$h "ives down to $om!ensate for the extra lift "enerated under !ower. Be have a 1 se$ond delay before

the elevator $om!ensation starts and a +. se$ond !eriod for it to rea$h full de!loyment. 6t throttleoff, we have a delay of 2 se$onds while the model slows and then a 1 se$ond !eriod durin" whi$hthe elevator resumes the neutral !osition for the "lide.

The 62 !ort does not !rovide an internal volta"e divider. 5onseHuently, to measure volta"es above+.+v, an external divider must be used as a volta"e sensor. or exam!le, to measure the volta"e ofa 4%$ell ;i*o battery maximum 1-.7v fully $har"ed3, a -A1 divider $an be usedG this will a$$e!tvolta"es u! to - x +.+v U 19.7v. Bith su$h a divider, 1-.7v will be seen as 1-.7v - U 2.7v as in!ut tothe re$eiver telemetry.

(ote that the r#ky :7 re$eivers only have only one analo" in!ut, 61, whi$h is $onne$tedinternally to measure the volta"e of the re$eiver !ower su!!ly. 6 $onverter is available to enableanalo" in!uts 623 to the di"ital #.*ort of the :7 . The :- re$eivers have an external 61 !ort likethat on most %series re$eivers.

Bithin the telemetry $ir$uits of the re$eiver, the value of the analo" in!ut between 0 and +.+v3 is$onverted to a number between 0 and 2 . This is en$oded di"itally and sent to the transmitter,where it is $onverted ba$k to a number re!resentin" the volta"e to do this the transmitter must be"iven the divider ratio3.

'n the s$reen shot above, the numbers immediately to the ri"ht of C61 $hannelD and C62 $hannelDre!resent the measurement Range , whi$h de!ends on the divider ratio of the volta"e sensor. orthe 4A1 ratio used to measure re$eiver volta"e, this value should be set to 1+.2 i.e., +.+ x 43. or a-A1 ratio sensor, the ran"e would be 19.7.

The number in the ri"ht hand $olumn .2 in the !i$ture3 re!resents the final Tele"etry read%out. 'f itdoes not a"ree exa$tly with the a$tual value measured with a voltmeter, the ran"e value $an bead@usted sli"htly. The usual $ause of ina$$ura$ies in the readin" is the toleran$e of the resistorsused in the volta"e divider.
