Looking at some of the performance series kits form Great Planes ( Yak 54, CAP 232, Su-31 )

Got a couple of OS 160's for EF 74" yaks I am building, but get the feeling the 160 won't cut it on the heavier Yak and Sukhoi kits......have been contemplating brillellli 46's, but also thought about MOKI 180's

My question is going from OS 160 to Moki 180, am I really just adding weight , or noticeably increasing the power:weight ratio ? ( never run a moki 180 )

Also if they are a great choice would they fit inside the cowls of these kits ( I know the 180 is about 15 mm taller to the top of the head for a side mount )

Cheers
