Hi Bob, First, I've never flown my A2 off a grass strip, so I'm not going to be much help there. I fly out of a 2K' paved strip, but I'm pretty much off well before mid-field. I rotate at 60mph, climb at between 500-700fpm on an average day (I live near the water), and a grand or better if it's cold and dry. I climb at 80mph, and after I've got a grand under me, I generally drop the nose a bit and climb at 90mph. I have the C-90 with a cruise prop. Even if the field was wetter or softer than you might have thought, it wouldn't explain poor performance in the air. I sure don't think you should be expecting this to be normal. When did you have the compression check last?
