unfortunately I got to answer that question by my own by flying mine with a 35RA on a xoar 19,8 . Once again the weight advertised by AE is pure BS. That said the weight of your components is an issue if you wanna get some vertical performance.
i also added a smoker system wich I flew for one day because it was like flying a Cub so much the performance went down.
So the smoker system and the benett muffler went on permanent vacation.
honestly a 45cc is required to really have fun and keep some extra power to get out of trouble.
also its very sturdy! built like a Mack truck!
bottom line is : I love the flying part and hate the power to weight ratio
yep an advertised low weight is a seller.
