OS FT120 and FT160 Gemini differences

I had both an early Gemini 120 and 160 apart and noticed that they were very different. It seemed like a good thing to make a video about. Here's a link to a review of the 120 when it first came out https://sceptreflight.com/Model%20Engine%2... And one for the 160 https://sceptreflight.com/Model%20Engine%2...
