Boss,

I'm running a YS 1.20sf Thats what i had kickin' around! and i'm glad i did! Very fun combo! I'm running 5475 all around! they seem to be working fine,As for the air frame no issues to date! Go with the 1.10 you won't be disappointed! I'm not sure of the casing size on the 1.10 but on the 1.20 i had to trim out a bit of the motor mount to fit mine in! if you have to as well just make sure eveything is even top and bottom! you shouldn't have a problem.As for a bat just using a 6.0v flat pack jr 2700

I did my first rolling harriers with this plane! very fun! If there wasn't snow on the ground i'd be out pokin' holes in the sky!

have fun!

cheers! from Canada!
