WP YAK 55 EPP 800 RCElektro Flugmodell Graupner 9406 YAK 55 EPP no.: 9406
The Yak 55 EPP is an indoor model aircraft made of 10 mm EPP foam. This model has excellent aerobatic characteristics and is also very well suited to beginners in the aerobatic field. The battery is changed by means of a Velcro binder. This makes the model very suitable for everyday use and ensures simple handling. A conscious decision was made to include no motor with the model; this enables you to customise the kit and to re-use existing drives and RC components. Motors of a comparable output and size to the drive we recommend can be utilised. The model is very simple and quick to build. Anyone who has ever built a silhouette model can expect to complete the build in around 1 hour. The 10 mm EPP material makes the model very sturdy and easy to repair.
