Rotorflight 2

De mult am dorit un controler FBL care sa aiba functia de rescue (Horizon, 6D, etc.) care sa ma scuteasca de reparat heli si de dat bani pe piese, dupa o manevra nereusita, si asta la un pret mic. Acum visul pare sa devina realitate cu softul Rotorflight pe un flightcontroler MATEK G474-HLITE (aprox 200Ron de pe Ali).
Montat pe un frame 450 HK cu majoritatea pieselor Align, head DFC, motor 3600kv, esc cu soft BlHeli, si un senzor RPM simplu facut de mine dintr-un sensor hall SS460P montat pe frame in apropierea motorului. Sensorul RPM este o componenta foarte important pt. rotorflight in calcularea filtrelor de vibratii, governor, etc. Exista si ESC-uri care ofera acest semnal dar eu prefer sa am fizic. (preferabil de pe main gear dar nu am vrut sa lipesc magneti)
Dupa setarile mechanice - la care ajuta multi is configuratorul - am facut maiden flight cu setarile default si heli zboara destul de bine, acum urmeaza fine tunningul valorilor PID, filtrelor gyro si testarea modului rescue.
O gramada de informati pe net:

Am updatatat la vers. 4.4.0., din pacate am pierdut setarile din vers. anterioara dar dupa cateva "exercitii" setarea pe masa (fara PID-uri) merge repede.
A trebuit sa schimp servourile de corona 919 pe K-Power DMC809 pentru ca erau deadband-ul era prea mare. Cu DMC809 merge foarte lin. Am schimbat si head-ul la cel de Tarot DFC care mi se pare peste cel de Align.
Ramane zborul de setare PID si filtre pt. vibratii.

Cum ai lipit pinii ? Orizontal sau vertical ? Ai pini cu ambele orientari in cutie ?

Am lipit orizontal si montat cu pinii catre coada. ( set gyro_1_sensor_align = CW0FLIP ) asa am avut si K-Bar-ul.

Vine cu doua seturi de pini si doua cabluri.

4 servo
1 esc
1 RX
1 RPM
si mai este una de care nu imi dau seama - ce ESC ai? e cu BlueJay?

ESC unul simplu de Turnigy Plush 40A cu soft de BlHeli. Am schimbat firele de GND si 5V la sectiune mai mare si din silicon + fir de la acu+

Integrat senzor hall bipolar cu pullup 10k SS460P la TME 6.51RON/buc.
Pentru proba se poate baga intr-un connector 3 pin dar pentru proba, nu recomad folosirea asa pe model.
Eu am cositorit pe o bucata de placa (reciclat dintr-un scaner sau imprimanta) si am mai adaugat (optional) o rezistenta de 22K intre pinii de OUT si GND limitand astfel tensiunea de iesire la 3,4V.
Probat pe model functioneaza foarte bine si este de ajuns apropierea la 1,5cm de motor.
