I have just built a Boomerang which is also by Seagull. Very easy to build although the instructions leave a bit to be desired. They have you fitting undercarriage, engine and then tail section, which if you follow makes the model all to difficult to handle. Beware of the "strong covering". I managed to puncture the wing very easily by not being carefull enough when joining together. Must have left something on the bench. I also did not cover the wing with cling film when joining and got a bit of epoxy over the wing and the colours do not like acetone. Overall I am satisfied but will need a bit of tuition as I am not to sure how robust it will be in the enivitable un-planned landing. Yet to take it out as it was a bit gusty at the weekend. I have an old Maracado which I am renovating. It has foam wings covered with vineer, however, looks a bit more robust. A good bit heavier than the Boomerang but will do as a trainer. Hopefully this weekend will be kinder and there will be a tutor at the field. Will keep you informed and good luck Edit I am not an expert and hopefully somebody more experienced will contribute
