RE: A newcomer to the full-size F3A models
Dando, before spending a lot of money on trying to get your model under 5 kg, first check if anyone is actually measuring this at your contests. As far as I know, only at world championships and European championships will this be done. Mostly everybody is very happy that another person takes the interest to compete.
We have a scale at our contests for those that are interested to weigh their plane just to have it at a calibrated scale. We just want everybody who can to compete and enjoy himself.
