oh thanks thats good news, i will start with 5 mins also i'm going to test fly it at a larger field first as we only have 100m max no spare no run off if its ok then i hope to fly it at our field.there has been loads and loads about the C of G but i'm guessing 185 from leading edge it the place to be? as a matter of interest what does your and anyone else's weigh? mine seems heavy. haven't weighed yet but will before flight.
