i have playing with convergences also. except i have been bringing mine right in 150 or 200 for both. i did try the yum yum settings you sent me/posted (1000) but then i twigged that he flies VERY fast, so closing at far greater speed than i m able to achive. so getting back to all firing at one, hopefully if i can get to within convergence range, when i open up, "he should go bang!"
