After doing a inspection at Mr.Patakes home running the turbine at night for a short period, trying to spare the neighborhood as well as we could, we checked the flying surfaces throws and CG as recommended by Mr. Anton. We also checked for bubbles in the header tank and radio link range . So runned out of excuses, we went to the club next day at noon ... the problem was that the wind was gusty and at 90 degrees.. I hate when this happens , but a promise is a promise, so I wasn´t able to chicken out the test flight.
