Ok, this is a slightly complex question.

1) I am committed to setting up a Phoenix Extra330S. I had actually bought it as a test bed for my 75ax but turns out the 75 is too small for 3D for that airplane. A collegue has the Phoenix Yak 60" which is essentially the same airplane.
2) Now I want to avoid buying a 95AX right now.
3) I have a 120ax which was bought for a Funtana125. I dont intend to set up my Funtana for another year atleast (unlessI crashsomething).
4) I could use the 120ax on the Extra and get a Dle20 for the Funtana, but the way the technology is evolving on gas engines, there may be something much better available by the time I decide to setup the Funtana.
5) Then again, I am not sure I should put a gasser on the Funtana which has a fragile build.
6) So far I have been only flying 60 size models (GP Reactor 46 that I just crashed but is repaired and Phoenix Topstar 60 which is same as H9 Frenzy /Twist60) and I am not sure I should make the jump to a 120 size engine so quickly

Given above description of my predicament, please suggest what should I do
