I am in the Johannesburg area and it s the first time I am posting on this forum, please be patient for my terrible english and my noob questions
I am building an octo, using for the first time the APM 2.5, I am reading/studying a lot but I really need some help.
Basically the octo will be powered by two PDBs, one powering only escs and motors (6s) and the other powering the fpv,vtx,flight rx etc.(3s or 4s) The two PDB have a common ground. I am thinking to power the APM from a dedicated battery and BEC.
- I am using the Platinum Pro 30A opto ESCs which don't have an on board BEC, so I am planning to cut off the red cable, send only the white cable to the matching output on the APM and connect the black cable to the common ground of the PDBs. Would this work correctly?
- I will use a Futaba T8J linked to a Delta 8 frSky rx. If I put the jumper on the rx signal pin 3 and 4 and a jumper on the APM inputs signal 2 and 3 will I be able to connect the rx to the APM by the only signal wire on CH 1as the APM will use the PPM streaming? Will I need to update to the latest
ArduPPM_v2.3.16_ATMega32U2.hex or is there a way to check if it is already loaded with the APM firmware?
- I found this sensor at
http://za.rs-online.com/web/p/hall-effect-sensor-ics/7248739/ I would like to put it in the main PDB (ESCs and MOTORs) does someone know if it'd work with the APM? Where would I connect the three pins?
- Lastly where do you guys buy batteries in big quantities? They cost a fortune!!!
Sorry for the many/long questions, any help or reference is highly appreciated, thanks a lot
