Hi Paul,
I may be the one Tim is talking about. I have one and it's a good flier if not short on air time. Just consider the size of the miniX at 4-1/2" and you'll agree the 60mAh battery is about all that will fit in it. I get between 1 - 2 minutes of flight depending on how much I run the tail motor.
If you have the room, you might want to investigate the 6020-1 & 6023-1 helis. They are around 7" - 8" and are the big brothers of the miniX and all cost in the $25 - $30 range. A lot of folks with them (the larger ones) are upgrading the battery to either a 210mAh or 240mAh with the 210mAh being the best compromise between more weight and less flight time and less weight and a bit longer flight time.
