PPM no radio input via APM

I have an APM 1280 board, uploaded Arduplane v2.33. Since the upload an after radio setup I cannot get the APM to recognize any TX inputs. It will only recognize inputs when connected to my computer via USB but not when in normal setup. the ppm light remains solid blue. What am i doing wrong?

Hi Petrus,

 

Ek is in Clubview. Jy kan gerus vrae vra.

 

Groetnis

Baie dankie Sarel,

 

Ek glo dit is makliker om met iemand te gesels wat alreeds deur die moeite gegaan het en die die autopilot uitrusting verstaan. Soos vroer gese, ek is nuut tot die idee om n vliegtuig op sy eie te laat vlieg sonder dat ek beheer daaroor uitoefen maar is alreeds bekwaam in radio beheer en het alreeds n paar vliegtuie ontwerp, gebou en gevlieg en het daardeur geleer hoe om dit reg te doen.

 

My idee is om n klein besigheid met die UAV's te begin maar soek die regte en goedkoopste manier en toerusting om te leer en klein te begin, daarom die volgende vrae.

 

  1. Ek het alreeds n JR 2110X TX Radio en verskeie RX ontvangers, kan ArduPilot Mega daarmee koppel of moet ek iet anders aankoop?
  2. Ek wil as n "testbed" n TeleMaster tipe vliegtuig deur my ontwerp gebruik, of sou jy iets anders voorstel?
  3. Wat is die reik afstand van die ArdupilotMega, ek weet die huidge voorstel vanuit die forum asook moontlikke reels soos uiteengesit deur SAMAA en Burgerlugvaart is dat die vliegtuig nie oor n seker afstand maak gaan nie (kan nie die presiese afstand en hoogte nou onthou nie). Kan Ardupilot tot 10Km radius gaan?
  4. Opeenvolgend tot die vorige vraag, as ek tot 10Km radius kan gaan en die vliegtuig is op AutoPilot dan is dit mos alreeds buite die bereik van die radio beheer TX, is dit moontlik?, neem die Autopilot totale beheer oor sodat die RX nie deurmekaar raak soos waneer die radio nie aangeskakel is nie of verbinding verloor het?

Groete

Petrus

Hi Petrus,

Thanks for the response.

I live in Pretoria but am originally from the UK (came out to the CSIR), and I am afraid my Afrikaans is very poor. I have a Masters degree in electronics and many, many years in R&D.

Regards,

Trevor
