I've been flying in local parks for 5 years - since I started electric flying.   I fly a Formosa, brushless TwinStar II and an Easy Glider with brushless motor. I'm currently eye-ing up one of those FMS warbirds.   Is there a problem here? Peter seems to have got the right idea - but a lot of people are dismissing his efforts. Why is this?
