I flew my Evolution 10 GX powered Pheonix 40 Spitfire again this week and continued to have engine running problems. The engine missed and ran rough again even though I changed the setting on the IBEC. I am quite sure I have a problem with the IBEC or the ignition. I removed the IBEC and installed a second switch and battery. If this does not cure the problems, we will know the ignition is acting up. I also flew my Evolution 20 GX powered GP Stuka and it continues to perform well.

Best wishes and good safe flying.
