Title: one shot 125
Post by: nacholibre on April 17, 2016, 08:21:05 pm
I got me some one shot 125. i usually use reg 12a afros or plain simonk. can someone give me the run down that used both before. i still lack a bit before i fly them. can they be used with pwm? i know you have to specify that you are using them in set up and they're suppose to be smooth. I didnt think you could get smoother than afros... but thats just what ive read. whats the real deal? what do most pilots use. and should i be using ppm? because i dont think my receiver supports that.Have a great Sunday friends :)

Hi nacholibre,

first, which controller are you using? CC3D has some limitations about OneShot125, afaik you can only use it with PPM input. On Revo (often called Revo) you have no limitations about using OneShot. I've used it with PWM, S-Bus and PPM on the Revo with no difficulties, it's just set it up and enjoy :)

You can read all about the different options here: https://librepilot.atlassian.net/wiki/display/LPDOC/Hardware+Configuration

hey Cato, thanks for the reply. I use a little of them all. but i really like the revo. i have a lot of cc3d's though. But i dont think i will purchase anymore of them unless i get in a pinch. So i will be putting it on a revo board for sure. Especially after the info you gave me. I just seen some at a good price and like trying new things. And ive never used them or flown an aircraft that had  them. Im really partial to the afros. when i started i went with whatever was the cheapest. usually simonk generics. So the first time i used afros i was blown away. But theyre expensive and sometimes i have trouble getting them quickly. but hobbyking has had them for 38 bucks for a set. these 125s were 41 i think so i said why not? ive even been known to mix them up. when i dont have simular escs on hand i just slap whatever i have on there or take two bad ones and make one good one lol.  i've been reluctant to try any other way but pwm i guess im comfortable with it. But i need to step out and try the others to free up some ports. Once again thanks for sharing your knowledge friend. happy flying and have a great Sunday.Also i like your quad in your profile pic.

I myself started with the cheepest ones available, but even those are OneShot125 now. Recent Afros also usually will do Oneshot (mine do). The point is that OneShot reacts much quicker, so you can tune your quad up and get much more precise reactions and locked in flight, as some advantages.

I fly both my quads with OneShot, as you can see from my signature :)

thats the way.. oneshot onekill lol yes i have looked at the programming parameters on the afros but i never tried it. when i bought my first set of them i also bought the little programmer afro sells. but sometimes when i go to messing with stuff im not 100% i dont get to fly at all till i figure out what i did wrong.lol i recently put gps on one of my revo units and it drives me nuts having to wait for the gps to lock. i didnt know at the time i was buying a almost obsolete gps (op gps mini) and i leave in the middle of nowhere. i havent even been able to use any of the gps flight modes.i just get to wait for it to lock and then perform poorly. im trying to do some research and go ahead and get the best one i can next. its always something. i work on em as much or quite more than i fly them lol. my favorite one i call Johnny Cash. cause i bought it one piece at a time and it took months to finish. buying only one or two parts a week lol but i love it.

i never used before. i have no power to board. the escs only have signal and ground. how do i power the board and rx. and what hardware setting? im using pwm. and i have flysky i6 tx and rx. works with usb connect to computer fpr power and i have no system warnings. cant find much on youtube or google... need help. thanks

If your Esc doesn't have +5V wire you need a extra step down that provides +5V for board.

Good morning and thanks friend. i ordered a BW RC servo BEC UBEC 3A 5v early this morning. will that be good enough or do i need a specific one? i have a PDB with a 5v outlet in my parts cabinet,would that work with a servo extension wired to the receiver until the UBEC arrives?
?

yes, Pdb with +5v are designed for this purpose.

well i might just get to fly it today then :) i set the highs and lows with a little lipo i had fro my servo tester. Theyre very smooth and quite. work work work to fly for a few minutes. thanks again bro

My receiver doesn't support ppm :-[ but i was able to get them working in pwm mode. I'm ready to upgrade to so new equipment.TX/RX and whatever else is need any suggestions? f5soh i respect your opinion and would like to know what you think. and also may i ask what is the single winged craft in you profile pic? It looks really cool.

You can use PM from the menu in top/right corner.

 How did you get it to work. I am building several oneshot builds with cc3d boards, but the receivers are sbus only.

i used a PDB with a 5v output or you can use a 5v ubec and ran the 5v and a ground from the board to the receiver and put all my setting back to pwm. And it worked just fine. i used the dalrc one shots and they have been running smooth.. I got the receiver in but just havent got around to switching it out yet. but i would like to see what the diffence is. But im having troubles with a revo board so i dont know when i will get around to it. all i can see by looking at them is they have no pwr wire so they all share the one. Im sure its not proper but it works. i wouldnt think it would mess up the escs but i dont know that as fact but im not too worried about it ;D im pretty hard on parts so i try to have backups of standard stuff so i have less down time. i work on them 100x more than i get to fly them. it can get frustrating. but every time i think im out,they pull me back in ehhhhh! ;D good luck friend

ahh, I see. I should have read the thread a bit more deeply. I see now you were having an issue because of opto's. Love Opto's btw. I thought you were saying you got oneshot to work on a cc3d board with sbus. Since someone else had said cc3d only works with oneshot with pwm I was eager to hear if you had found a work around.  I build and sell racing machines in my spare time, and to help fund my hobby (barely), and just bought three cc3d boards for my next builds. I have a bunch of Phantom2 TC RX combo's I use to sell RTF packages, so I was planning on doing this. Sure I still could, but really want to sell one shot capable machines, so may just make them BNF packages for the cc3d boards, and make a couple more expesive revo packages for RTF packages. Already digging myself in a financial hole, might as well go a bit further.  Thanks anyways, and glad to see you go your power situation figured out. When possible I get one BEC and the rest Opto, but my new builds are all super light opto only esc's so they have to have pdb, which is fine, cause it is useful for LED's and FPV stuff too.

Hey Nacho, I tried to send you a message, but it seemed to do something weird saying I already sent it when I hadn't and shows nothing in my outbox. Let me know if you got a message from me please.
