Assuming you don't have heavy wheels and tires. If you do, might want to put in a mix.

On gear that rotate back, I retract my gear and balance my model inverted, dry. Makes for an easy balance.

Our composite Scalecraft Corsair (54" span) has been balanced like that for years and has always come home safely. Of all our composite models, the Corsair was the most forgiving at slow flight.

If your CG is off, better to be on the nose heavy side. A properly CD'ed model will land far easier than a light non CG'ed model.
