Thanks for the advice Dave! Thats why I asked in here. I have never seen the G2300 engine except in the catalog. I se alot of messages about this is a 120 size plane not 60 and it needs alot of weight up front to balance out that is when I got the idea about the bigger engine. I have the G-90 on my 66" VF 300S and I love that engine! I like the sound of the four stroke. I think I can get a Magnum 120 for about the same price as a Saito 100 four stroke. Do you think it would be better to go with the Saito 100 Vs the 120 Magnum? From what I hear the Saito is alot better engine but would the Saito 100 four stroke pull it as well as the Magnum 120? I am not speed crazy I wanted this plane to look scale with enough engine hid under the cowl to pull it nice. At first I was going to go with the Magnum 91 four stroke but after hearing that this is more of a 120 size plane I got scared.
