Yes, the soundunit works better as I expected ! Meanwhile I've flewn her for 3 times and it's an amazing experience! I'm very happy about the result- only thing it is, it's the C172 sound, but thats close to the 182..
The soundunit with 40W amplifier comes round about 100 €, and it's a benedini (benedini.de). Extra weight within 2 speakers and own batterie 3S 1000 : 500 gramm
But this big bird will carry the extra weight easiely, only the landing speed will be slightly higher, cg is back to 108mm to avoid beating down the nose gear strut , and I 'll try to install vortex generators for extra slow touch down speed...
Everybody loved the little "aircraft" at the airfield!
Flight video coming soon !
