  • its ok sorted found the culprit through looking at my logs

    gps sat count went to zero causing it to think it had breach the  theshold

    and motors went full bore 

     faulty gps lead

    but some logs reported rtl others did not

    but it has cured it

    phew was running out of props

    hot glue gunned connector on gps and now flies great


  • Logs plese
