Multifun - fun to the n'th degree! The model could be flown with or without a motor and with three types of wing. One model should therefore satisfy a number of users with different wishes. 

The Multifun is suitable for beginners - with them in mind the separately sold wing with upturned tips was designed.

An experienced modeller would enjoy most the powered version with wings without dihedral. This configuration gives to the model almost the behaviour of a fully-fledged aerobatic machine.

In any case the model has pleasant flying characteristics and a low minimum airspeed. Due to its nimbleness and low minimum speed it is suitable for flying in the backyard.
