RE: First
Just to let you know the GP Little Toni will not do 120 with a 60-95 size engine. and a 120 will be lucky to get 110. The fastest one ever was with a OS 91 DF engine and it only got to 150. you could put a YS 115 in it and get 130.
A real good option for you since you have flown 3d and want some speed will be the GP revolver. you can get the 46-55 size put a saito 125 or a OS 95 AX in it. You will have a plane that can do 120 fly sportsman IMAC with it. You will be able to hover it and even flat spin both up right and inverted. I had a 120AX in mine and it was 145 on GPS.
You can even get the bigger version which is a 70" wing and put a DLE 30 in it. run a 16x14 prop and will scoot along at 120 also but its a bigger plane and flies even better than the smaller revolver.
