My 30mm EDF weighs 71g and flies very nicely. Fast and loop capable, no problems. I think you could go up to 80g but you would want a fairly low-drag airframe to compensate. You could probably even go 100g if you had the right kind of model built to DLG standard. ie. ultra low draw, smooth skin, low frontal area, etc.
You may as well see how it goes as is so that you get an idea of what to aim for if you decide to build something different. It's all about experimenting and learning, isn't it?
