Tower Pro MAG 8 ESC 20- Programming?

Hi folks,

I just picked up one of the NEWEST Mag8 20 amp ESC's from UnitedHobbies. For $9.99 I just had to try it. So far I've had no luck programming it with my TX. The beep codes are COMPLETELY different from the instructions I've seen posted around the net (so please dont re-post those instructions here as a solution)

Here is what I get when I fire up the TX at full throttle, then plug in the ESC to program:

b-be-bee, be-be-bee (musical tone)
<5 second pause>
<5 second pause>
be, be, be, be, be,
be-be, be-be, be-be, be-be, be-be,
be-be-be, be-be-be, be-be-be, be-be-be, be-be-be,
be-be-be-be, be-be-be-be, be-be-be-be, be-be-be-be, be-be-be-be
beee-be, beee-be, beee-be, beee-be, beee-be,
be-be, be-be, be-be, be-be, be-be,
beee-be-beee, beee-be-beee, beee-be-beee, beee-be-beee, beee-be-beee
<2 second pause>

If I throttle down 50% during any of these beeps I get a 'be-bee', and then more codes to follow, but throttling back up doesn't seem to program any of them.

Anyone else have these same ESC codes?
Anyone else have any luck deciphering them?

Well, now you know why they're so cheap

I bought a Hextronic ESC from UH and it also came with NO INSTRUCTIONS

Your beep codes appear to be similar to those in the current Towerpro ESC User Guide, but with a few more options. According to the instructions, you have to pull the throttle low for 1 second to save the settings. Have you tried doing this?

Yeah, ya get what ya pay for, right? Which is why I only bought one. If it ends up in the trash, it's a cheap experiment

And yes, I've tried *ALL* the instructions I could find with similar codes and none of the methods have seemed to work (full throttle, partial throttle, no throttle.. blablabla ad nauseum)

I've seen a few threads on other boards with people having the same issue as me- but haven't seen any solutions yet.

Is there a reset or return to defaults somewhere that I can try?

I'll try and help.

I got one of these. If ya really want to get rid of it let me know.

Throttle 100 plug in esc. I'm using 1's and 2's instead of be's.
Let it do it's little song and dance.

At 1-1-1-1-1 during this sound pull to 50%. Tone will change.

You now hear 1-1-1-1-1 WAIT unless you got nimh's
2-2-2-2-2 etc..

2 is for lipo 2 cell. Push to 100% to select it.

3 is for lipo 3 cell. Push to 100% to select it.

You'l hear some tones. (It's saying OK)

Now you gotta start all over. I just unplug and re-plug to make it easy.

1-1-1-1-1 BATTS
2-2-2-2-2 BRAKE pull to 50% tone changes

1-1-1-1-1 push to 100% NO BRAKE
Little song plays. Go fly or start over.

Let me know if it helps. I could make a little video for ya if ya want.

I sure would like to see the video of how to program one of these as I have several ordered.

odd thing about the 2 I got from UH had 2 stickers on it one small green one with QC on it, and the other was on the back and had "acro" written on it. This one nearly refuses 2 cells and when it does something isn't right in the power that it puts out. The other programs using the directions I found on here and other places just fine, the one with the odd stickers...refuses to program anything.

Man, these Tower Pro ESC programming threads keep popping up like weeds. Please do a little searching in this forum before posting next time. Search for a master thread that starts with the word "Coution" (Caution spelled wrong) in the tittle. It has some hard work, re-edited instructions, and other info done by users that were way ahead of you. I just got a Mag8 30 amper with the green label and it programs like the last one I mentioned on there.

Urthman, your ESC appears to be the same one that I have, since it's making the same noise. Does it have the "ACRO" sticker on it? This one: TP 20A ACRO

I asked about programming from Towerpro's support. They replied:

"Dear Sir,

Thanks for using Towerpro products.
Please check your 20A ESC first to see if there is a small sticker "ACRO" type ESC.

If you buy this kind of ESC, it needs ESC setup box to change setting. If you don't have ESC setup box, it is ok too. Just plug in connector then it works just can't change any setting of it.

We will change web site manual soon. The manual you see there it is N type 20A . It's different than 20A ESC ACRO. That's why we put in a manual for your reference.

If you still have any problem to using that, you can bring it to your local dealer for total sulation help.
Thanks and best regards,

Now, they seem to have some instructions at Unitedhobbies pages. And the best thing, the programming box is available too. Programming box

I ordered one of those. It is on it's way from HK. I'll tell you guys how it works after trying it out.

yes my recent order of 2 of their escs with the 2410-08 and 2410-09 motors 1 one was the older model, and 1 was the newer one with the acro sticker. Being that it had a "QC" marking on it as well, I assumed it was either a faulty one or marked as being returned or something. I noticed a few days later that they had listed a new version having the "acro" sticker and that a program box was needed to change settings.

So I guess my next order will include the $6 box so I can program it. Anyone have one of these newer ones and know if it can actually be programmed for 2s lipo? The instructions say 3-4-5 cells but wondered why 2 was missing.

I just recieved a couple of Tower Pro Mag 8 18 amps ESCs with no instructions. My ESCs don't have the acro sticker on them. It looks like these instructions on the hextroniks website work for mine.

this guys from UH seem to be very funny *lol*

"f you buy this kind of ESC, it needs ESC setup box to change setting. If you don't have ESC setup box, it is ok too. Just plug in connector then it works just can't change any setting of it."

But they shipped it with 3s lipo cutoff and my motor runs with 2s (so it does not spin up).... seems i gotta wait for the damn controller to arrive

yep, same with mine...motor will spin up but waay less pull than my other esc on the same setup

The box works just all right. Way easier than trying to listen to some beeps.

Only thing I would like to get is some memory. When you unplug the battery, and then plug it back again, you have to go through all the settings again.

Hi , I just burn my "prog acro box" because i plug it with a 2s lipo ( 8.4V ).

I 'm french and i don' t understand in this thread , if i can re-prog my "Tower Pro MAG 8 ESC 20" without the box.

I have got a hellis honney bee and i must to have the "brake off" , and a soft speed acceleration.

I' m furious because on the datasheet of the prog box , it' s not writed that a 2s lipo can do damage.

I wish you greats flying.
