The Top Model Marabu is a popular European designed and manufactured F5J ALES sailplane. It has a 2.75M wingspan and weighs in at around 1250-1400g depending on your gear selection. The Marabu looks like an old school free flight model and that's because they use free flight building techniques in manufacturing and it is beautiful.
The problem with models this big from Europe is the shipping can be brutal and costly to get them in the USA. Esprit Model is looking to help and will be offering the Marabu for sale soon on the their website. You can see the Marabu at Top Model and be on the lookout at Esprit Model for when it is available.
