I hope this doesn't sound like I'm talking below you're experience level, and if I'm am, just ignore my reply and move on.
In all the years I've been flying helis (25+), I've never had a model that was trimmed for hover, then go up and fly straight in forward flight. That's part of the reason they invented flight modes and stunt trims, and when digital trims in each flight mode came along, I thought I was in 7th heaven. Anyway, my experience has been that for the "average" forward speed you choose to fly at, you'll need down trim compared to the trim used at hover, to make the model track forward like an airplane. The faster "average" forward speed (meaning the more collective pitch/power you're using), the more forward trim you'll need to make it track without pitching up. Hope this helps.
