MVVS .49 in a pattern ship ?
Hello!
It all depends what you mean by "top aerobatics"
The MVVS .49 with the No. 4248 minipipe (Long minipipe) and using a 11x6 APC propeller, at sealevel,using 5% nitro and 15% syntetic oil ( Motul "Mikro") will give good performance....not hovering capabilities but good solid aerobatic performance providing the aircraft is built straight.
The weight you mentioned ( 2,5kg)is rather high though, so do not expect racing performance.
Regards!
