YES - When you have Crowe braking as well, the wing efficiency is much reduced. With a lot of nose weight and the tailplane having to balance it all - it was just too much. Landing speed was a little greater than I normally use for the Intro. Hence my surprise and annoyance.

I have now cut the Crowe braking a bit, as well as reducing the nose weight. She now lands every bit as gently as the Intro and is a delight.

I think Alan is anxious that people do not start with a dangerously aft CG and thereby lose the model. I suspect I would be equally conservative if I was him. If you treat the recommended CG as a good starting point and reckon to work off a little bit at a time until you have it balanced the way you feel comfortable - then you will finish up a very happy man. Just remember to make the first few landings quite fast and/or test for a stall at a good hight so you know what to expect.
