Hey Tony,
I'm sure you're right but still I have to wonder how many orders they will be getting for 1.10's in the next few months, knowing that a 1.15 is coming out. And, your right, most of the ARFs everyone is flying are large enough for a 1.20, so the 1.15 is a natural since good 1.20's are getting hard to come by.
For those who built custom sized planes for the 1.10, they can just do like you and up the nitro.
Blessings, Terry
