Some years ago I had a Synergy where it was originally mounted YS 140 but I swapped to OS 140 RX. If I remember right the was only the nose ring that was slightly different but engine mount was the same. So I think it more or less plugg and play.

Not correct at all. I did a direct swap (1.40 FZ to 1.40RX) years ago and he OS delivered FAR more power. And on 15% as oppossed to 30%.
It's a direct swap the only change was the nose ring as mentioned plus of course you'll have to make arrangements and mount a giant 2 stroke muffler and some right thrust tweeks.
I had the FZ definately proppped with a 16x10 and the RX from what I can remember, a 17X12 and 18x10w.

They are dimensionally very similar but a small weight difference, throttle linkage and the space for the big 2 cycle exhaust. OS was very easy to run but not much on torque or throttle response. Keep a spare rear bearing handy and some OS type F plugs they will serve you well on 15 - 30% nitro fuel. The APC 18.1 X 10 was my favorite
