Castle ESC Endpoint Calibration with AR7200BX 

This video was made almost 7 years ago, and it still provided me with crucial information I needed to get my T-Rex 550E PRO DFC to throttle up with my DX8. The one step I missed was that the first time around, I set the throttle limits to 30-30 before I turned on the AR7200BX. But, I re-watched the video and did it right the second time, and it worked! THANK YOU!

Sir, I live in Oceanside, Cali. I was trying for the life of me to get this figured out on my own. I understand all that you have done to get this ESC work. I will do the same as soon as I get home. I thank you very much, and my hat goes off to you Sir... Great video post........

Very nicely explained - clearly and in detail. Easily understood. Thank you. Useful to me for when I could afford the AR6200BX.

By far, you have the BEST video/explanation of this calibration process!!! thanks for the effort!

Excellent video! Best explanation yet of the quirky nature of the AR7200BX when trying to enter the Castle calibration mode!

I just wanted to let you know, personally; I have been searching and searching for long time for someone that actually made some damn sense. You, my friend, are the expert at doing so. I just wanted to personally thank you for your step-by-step, easy to follow, down-to-earth explanations. It was just absolutely amazing to experience that much understanding from one video. I've already set my 450L Dominator up and completed the build/process prior to watching this video. I wasn't using a castle creation but a lot of the things that you were covering correlated/answered other questions pertaining to oftentimes confused subjects that always seem to be popping up. Which leads to frustration and make you wanna quit. So again thank you for saving the love of the hobby for me. I mean that.... obviously,.......I took the time to check my grammar and punctuate lol

Worked great - thanks! Was stumped for about 2 hours and then found your video.

I've watched a dozen of these vids and couldn't figure it out. Yours is the best! Watched it 1.5 times and got it. Thank you for the detailing in the process. Awesome job! Cheers to you, Thumbs-up

i just did this on a plane and not a castle ESC! Thanks man! Made my day!! :')

A huge THANK YOU For months now I try only with your straight I managed to bind again ar 7200bx after finishing end points

Nice job Hal! It's always great to learn different methods!

Great video!!! Finally got my Blade 550x in the air after watching this video!!

Nice and Clear Vid , much better than some others I have seen :-) I have the CC Phoenix , Jr 9503 and Spektrum Rx 7010. Thought I had it set , but when I plugged batt in , ESC got VERY Hot ! ,Unplugged quick ! Need to watch Yur Vid again, to understand the use of the Pigtail and seperate battery . Now to watch again.. Thanks for the Vid tom e

Cheers 4 advice , worked great thanks for taking the time to explain everything thanks again stu

Thank you so much for this, worked perfectly. Really great information in the video, Thanks again

Thank you for making this video.

Yes. You have to perform a throttle calibration on all the CC ESCs and program the operational characteristics via the Castlelink Software.

Im ready for my first build on a 600x so gathering as much info as I can . I don't know if I will need this but it is saved in favorites for when I get stared, thanks a lot. really nice helicopter by the way

Great video...very clear explanation....thanks!

For those of you that have watched my video, I thank you for your viewership! Some of you (very few) have had issues saying that at the end, the procedure didn't work. Remember to rebind your AR7200BX to your receiver after you find the calibrated endpoints for the ESC. Or your receiver will use it's last known endpoint settings (100/100) and the ESC will not arm.

thank you Hal love your ingenuity I am going to make a similar setup very easy to follow. thank you.

Very clear instructions. Good job!

Thanks Hal. this we very clear and useful

Thank you for sharing this information !

Thanx for your time and share..

Also a 6.6v Life pack as been running my trex 600 servos and fbl since i got my 600e pro and its fine

I find it quicker and safer to bind to a spare standard receiver and hook the ESC to that and setup the transmitter endpoints. Then rebind to your heli and go.

Life saver thank you so much

nice job buddy great video

Great vid, I have the same equipment, but after programing everything and starting up I was getting a flashing yellow? what the heck? Found out it was in logging data mode ,so I just disabled it, don't need it! Thought it was a problem with esc, Thanks

this worked perfect!

My talon 90 just keeps blinking when i move the travel rates up, it never beeps even if i pas 100

Thanks...

Wow thank u

hiDid you hook the switch and the wire you made up on the red and black to the battery plug . my battery is a 22v what size do I need to use for this hook up.

Obviously it worked for a lot of people but I have a concern about the red wire deal. A buddy of mine says he also disconnects the red wire from his ESC's when using a separate power supply for Rx and servos but the instructions with my CC Phoenix Edge HV 160 specifically states do NOT disconnect the red wire. I'm kinda leery about the whole thing since the maiden attempt of my Assault 700 I barely got it half spooled up and my Turning dlux 160 amp HV ESC decided to incinerate itself. I'm also using the AR7200BX. Luckily the only damage was the ESC.

great video mate thanx but i did here that the castle creation esc,s dont have a built in bec so theres no need to take the red wire out is this true ?

I am working with an Elec sailplane , noticing yur 6.6v Batt Oooops which I don't have . Do have 4.8 v paks , suppose those would be suitable ??

hi nice video man! but if i put it down to low stick then i dont hear any tones...

hey hal. ....do u set the endpoints back to 100/100 when its all done and rebound, or leave where they confirm and add +2 clicks like in the video. and those are our new endpoints

Hal... This is great! can't wait to try this... I just bought a 700fc3 (one flight) without a receiver. I put an ar7200bx on it and bound it right away to my DX8...(with no issues) set up the ar7200/DFC head per all instructions (perfect) I've been struggling with ESC (castle 120 HV-no card came with it) won't spool up for anything! The heli has a BEC, so I'm thinking I need to still make up a harness for the ESC for binding purposes... or, sinse I have a BEC, should I permanently remove the red wire from the ESC harness?

Thanks so much for this video. My only question is did you leave the travel adjust at 92 and 90 when you were done or did you put them back to 100? Im assuming you left them alone but I just wanted to double check. Thanks again and take care!

Before calibration, what is the bind procedure for the esc? I have an Align Trex 700 with a Beastx flybarless system, a Phoenix Edge HV 160 esc, and a Spektrum DX18... A technician at a hobby shop was able to the esc to bind to his Soektrum DX8 but was unable to get a bind on his DX18. I have searched high and low and made many calls and cannot get any direction. All Im asking for is the binding procedure for the above mentioned equipment if possible.

I followed the steps in your video and it worked great. When I run the helicopter on the bench the motor will stall when I bring it down to low throttle and back to high ...any ideas?

Cant get mine to work. DX8 G2 with Castle creations 120A HV esc. did everything u did unplugged my Castle pro esc. hooked up external pack after making extention with red wire pulled. leaving at 100% end points turned on AR7200 after it booted switching to 30 30 then high throttle moving numbers up it never beeped for me.

I watched your other video as well but im having a hard time setting up the auto rotation bail out, actually i have never been able to get it to work with an AR7200BX. I set up the endpoints as you did in this video. Then i plugged it back to the castle link and enable the "autorotation mode" but now the esc will not arm, thus i can not set up the throttle hold percentage?? I would love any help to get this going thanks!

thanks for the info, I just finished the exact same set-up. Can you give me your set-up for the ESC and what are you running for head speeds and tail gains. I fired up mine but the tail is very sensitive meaning oscillates really bad. Thanks Jeff

Also, if u can help with the bind procedure step by step, do I do the calibrations after that or do i do the calibrations before the bind?

hi, did as dire.tutto ok but it does not work, if I remove the battery to another flight. I have to raise and lower .Otherwise gas does not work. My dx radio 9 ar 7200 bx trex 550 dfc talon 90 because?

is it ok to use a standard receiver for calibration and then rebind to the Bx7200?

Another heli, someone said i need o calibrate the esc even tho im using fixed rpm mode in the castle?? is that true? and i cant do what you did in the video if i have those set can i? right now i have norm set to 30% flat, stunt 1 set to 70% and stunt 3 set to 100%. would i have to just set my throttle curve in normal to do the calibration? then just set back to a flat 30% to fly ? or do i need to change something in the ESC first? Thanks

Okay..you lost me at setting the travel in ur tx at 30 30....1. you sed forget about the numbers..ther not important....why do u hafta set them numbers if not important? 2. What does 30 30 do...and theres nothing like that in my tx (dx6i) i mean i have travel adjust..what would that be in my tx?

Do do you have to do this with all CC esc? As well as program in your pc to run them?

Can anybody explain the 30 30 on the travel adjust?..i understand about seeing the pulse...but whats the signifcance of the 30 30?..why not 0?

Can you elaborate for set ups that use a bec? I run 1 6s battery that powers both the AR7200BX and the esc.

what happens if you dont calibrate the sticks? will it stil fly?

My friend, I've tried setting up my 90's talon endpoints on this AR7200BX with DX7 black, but the ESC does not recognize the throttle. What can it be?

Can this be done using a dx6i?

I wanted to change talon, I thought I was dead. Italian forum absurd Red Baron, nobody knew.

Didn't work for me!

Warning DO NOT USE THE DAT/BIND it shorted out on Life pack for a second and smoke ar7200bx is fine and my pack is ok
