+Michael Preyer The FF200's are a great little motor, small and powerful, and as you say, cool sound. With the FBL setup and Xtreme 200SRX 8 degree blades it's a real stealth machine, really quiet although the ESC setup I have now doesn't give that nice slow spool up

Appollo scott Hope it goes well for you. I've just got this bird running flybarless now with the same double brushless setup. I think there are better tail motors around now, I have an 1804 motor to try on my next build which should be a lot better than the setup on the 912. I'm using ESC's with BLHeli software now for the tails. It's definitely a nice way to go and if you can flash the software, you can optimise the tail settings. Unfortunately that either requires some micro soldering, or connection via an Arduino rig to flash. Anyway good luck with your build :)

FlyingboatsRCG Thanks again for the good info, I can only wish the guys from WL would read this stuff and incorporate some of our mods into their products so that we don't have do so much work just to get these things flying right. However it's fun though tinkering with them, it's like it's own hobby in a way. I had blew out the pcb board on my v913 dual brushless and decided to replace it with a leftover MJX reciver that I had laying around. I got the helicopter from Bangood and it had a F45 main and tail brushless esc combo soldered to a V913 pcb board. I baught two hobbywing 20A esc for the main and tail rotors. The main works flawlessly but I cannot get the tail to work. I have tried everything except flashing the tail esc but instructions for that particular esc is somewhat lacking. I finally gave up and orded a mjx F49 brushless tail motor kit whose esc should contact right up to the mjx reciver without problems. I'll post some videos when I am done.

Appollo scott Actually was researching last night as I have a DYS 10A ESC with BLHeli and wanted to solder some flashing connections to update the settings. Couldn't find any info on the connections but Banggoods have the DYS USB tool for flashing. Just plug the ESC's servo type plug into the USB and you can flash and update settings without soldering! It's for the DYS SN range and there a re a good number of ESC's from 10 - 40A. With BLHeli it will take a signal off the tail FET gate pin. BLHeli autodetects the signal on bootup and autocalibrates to suit. This should allow a brushless tail setup but there's still some setup required.

Tail ESC is sitting on top of the main motor ESC, under the battery. Connections are power in (shared with main ESC), signal comes from the gyro, and the same 3 wires to the motor. I checked the setup by plugging into the throttle signal first, before plugging into the gyro once I knew it was all working. Good luck with your build!

How did you link the ESC? Where were connected? You could send me pictures on my email? r.lopes.eletronica@gmail.com

Raphael Lopes Have a look at the full build log I wrote on RCGroups.com. www.rcgroups.com/forums/showthread.php?t=2169223#post29706577

As per the reply on your other comment. There are heaps of small quad motors around now, but looking through Banggoods this Racerstar looks like good value/weight and thrust: www.banggood.com/Racerstar-1306-BR1306-3100KV-1-2S-Brushless-Motor-CWCCW-For-150-180-200-RC-Multirotor-Frame-Kit-p-1065662.html?rmmds=search&ID=521310&cur_warehouse=CN I'd try running it with something like a 5030 2 blade prop, it may still have too much power in which case just cut the prop down a little. I've used something like these before: www.banggood.com/Gemfan-QX2-Propellers-For-Blade-200QX-Quadcopter-p-978335.html?gmcCountry=NZ&currency=NZD&createTmp=1&ad_id=353641305054&gclid=Cj0KCQjw2efrBRD3ARIsAEnt0ehE6NmXYQyD-CSVzWb3lDGWuDA4C8mo-Fcqw3N_wKsyCbuGP3iHgrgaAgy0EALw_wcB&cur_warehouse=CN

O motor principal é FF200 (5000kv), mas parece que estes não estão mais disponíveis no Hobby King. Os motores sem escova WL Toys para o 912 devem ser bons, mas você precisa correr um pinhão de 10 dentes. Motor de cauda é uma unidade de 2000kv que está executando um suporte Gem30 5030: hobbyking.com/en_us/18-11-2000kv-micro-brushless-outrunner-10g.html?___store=en_us

I initially fitted a new radio receiver and the tail signal was then sent to a single axis gyro, then on to the brushless ESC controlling the tail motor. I later fitted a 3 axis gyro and got rid of the flybar. The tail still works in the same way with a satellite receiver feeding into the Tarot ZYX 3 axis flybarless controller, then tail output to the tail motor ESC. If you're running a stock V912 receiver/PCB it should be possible to drive a BL ESC by taking a signal input from the mosfet that controls the brushed tail motor. You need a BLHeli ESC (probably best with the original BLHeli rather than BLHeli_S or BLHeli_32, LittleBee 20A BLHeli ESC's are excellent). Take a look at how I ran a BL motor on the FX71: kzfaq.info/get/bejne/bbCUY9GdsN-bp2Q.html

i mean gyro

Sim ESCs separados para motores principais e traseiros. Dê uma olhada em um dos meus outros clipes para ver como você pode adicionar uma cauda sem escova usando um BLHeli ESC (a nota deve ser BLHeli ou BLHeli_S e não BLHeli_32). Vídeo em kzfaq.info/get/bejne/bbCUY9GdsN-bp2Q.html

FlyingboatsRCG observei alguns videos, a placa receptora tem uma saída para dois fios do motor de cauda brushed, para eu instalar um esc para a cauda, eu deco plugar o fio vermelho quem sozinho do esc em uma das duas entradas? Essa e a minha dúvida. Esc da cauda tem 3 fios do motor, um positivo e negativo da bateria e um único fio vermelho que acredito ser a chave do funcionamento entre radio e a rotação correta do motor. Onde ligo esse fio vermelho?

Normalmente, as conexões de controle do ESC têm 1x fio preto e 1x branco (às vezes 1x marrom e 1x amarelo). O fio preto / marrom é - / ground, eo fio branco / amarelo é a entrada do sinal. Normalmente, eu conecto o sinal não às conexões do motor da cauda, ​​mas sim ao terminal do "portão" do Mosfet. Existem Mosfets para o motor principal e um menor para o motor da cauda. Os Mosfets têm 3 conexões, 2 das conexões são para o motor com rashed, e a terceira conexão é para o microprocessador da placa receptora para controle do Mosfet. Conecte-se a este terceiro ponto. Observe também quando conectado e ligar o helicóptero BLHeli ESC precisa ser inicializado antes que o motor funcione, então você precisa dar-lhes talvez metade do acelerador (o leme na posição do meio da vara é bom) até dar um único sinal sonoro, então dê zero acelerador (bastão de leme esquerdo completo) até obter um sinal sonoro mais baixo. Em seguida, o motor deve começar normalmente. Boa sorte!

FlyingboatsRCG entendi, o motor principal brushless foi conectado em uma conexão com três pontas onde é ligado o servo motor, em um daqueles pinos voce conecta o segundo esc, e isso?

Não. A 3ª conexão com o mosfet provavelmente estará na parte inferior da PCB do Receptor, ou, alternativamente, você precisa soldar a terceira perna do mosfet em cima da PCB (você precisa rastrear as trilhas de cobre do motor escovado conexões de volta para o mosfet, em seguida, conecte-se à outra perna que não está conectada ao motor). Não estou familiarizado com os últimos PCB V912, já que não usei um PCB de 912 em cerca de 3 anos.

I used a different radio receiver so did not use the stock V912 PCB. Wiring is just standard for ESC like this diagram: static.rcgroups.com/forums/attachments/2/5/6/7/7/6/a2458527-225-brushless%20wiring%20diagram.jpg If you want to run brushless motors off the 912PCB you can do it with BLHeli ESC's like on this video: kzfaq.info/get/bejne/bbCUY9GdsN-bp2Q.html

FlyingboatsRCG.. . How to change the tail brushed motor into a tail brushless motor. Thanks

Use the same approach as on the FX71 video I linked (assuming you have V912 PCB). Add a 10A BLHeli ESC which takes the signal from the tail motor mosfet on the V912 board, than add a motor. I used this one on my V912 hobbyking.com/en_us/18-11-2000kv-micro-brushless-outrunner-10g.html I bolted the motor to the old 912 tail plastic. Works well with a 5030 CCW propellor

FlyingboatsRCG. 1 more question. For tx/rx you use what model?

Devo 10 running deviation. I was originally using an Orange DSM2 6 channel receiver hobbyking.com/en_us/orangerx-r615x-dsm2-dsmx-compatible-6ch-2-4ghz-receiver-w-cppm.html?___store=en_us .Since I've changed to using flybarless controllers i use satellite receivers because they are smaller/lighter.
