I use this in an Ultra Stick. I use the 9XP expander for the 4 wing servos. Very nice. Just ong plug to get going at the field. Less room for error. I have no problems.

I also use a Berg receiver in a piccolo micro heli.

I have seen this brand outperform most other single conversion. IE others getting hit left and right when two bergs at meeting were rock solid! This did happen to be an indoor meet.

I have no range problems at all.
