RE: Quique Somenzini YAK-54S 73"
This plane is not designed for DA50. The Yak 85" is. Normally smoke tanks are good for 33% planes and up because the weight of the planes up to 50cc range let's say is about 12lb-18 lbs and smoke system will affect your wing loading. Quique is not a fan of smoke system even on his 85".
