I am about to get a twist and was curious to see what kind of engine anyone else has used. I saw the review video with the saito FA-82A in the twist, but i don't think i can afford that. I was thinking about a saito FA 80. I would like to put a big enough engine on it to make it hover, and i want to use a 4-stroke. Do you think a saito FA 72 or a OS FS70 surpass would be big enough? And is there any other hints or tips anyone can give me about the twist? Thanks!
