Simple and safe handling is given in every flight situation. The wing is in ribbed
Designed and equipped with robust CFRP spars. Frames, sides, ribs etc.
are dangled together and thus considerably facilitate the construction of the model.
The test models were covered with Oracover ironing foil. The instructions in this
given rudder deflections represent a proven basic attitude and should also be permanent
be maintained because exaggerated large rudder movements have a negative impact on flight
behavior can affect.

    1561/5000 The Impala Massimo is a high-speed delta! By his missing Control center is the emphasis very important and to comply exactly. The model has a full-symmetrical surface profile without S-stroke, whereby it does not develop any buoyancy without employment.
