besides changing your setting on your receiver you need to buya PCM Receiver.

I set mine to about 25% I want to come down but not at blazing speed.

I would try testing it at low throttle levels. and see how hard you fall from a foot hover with training gear on. Think about your Throttle and pitch combo that it takes to get up. and start with a little less. But then you might just want it to shut off. your futaba help line may be able to give you some advice on your heli.
