Nose Battery
I fly 2 identialy equiped R44's of almost the same year, the only difference being one has a night kit and has the battery in the rear port engine compartement and the other with no night kit up in the nose. Ive noticed flying with some heavy weight guys that they can easily run out of aft cyclic in the machine with the nose battery. The one heavy guy flys both machines and ive warned him to be aware of the difference it makes.
