Yeah, that's the problem and I've learnt it hard way during that Beta (you know, lots of money). I was easily crushed by GRN wing that consisted of... two snubs. Terrifying experience for the crew I must say.
I have idea for that:
Tell them about Midway or sinking IJN Yamato during World War II. This is where small (wooden or metal) planes were proved superior to the huge bada$$ dreadnoughts. (Well, it took some time to sink Yamato on the other hand...)
