I have found that if I reely manage my speed well, it will hang with just a good hard toss, so I took my satio 1000 off and reealy saved wate. Now it ways 1/3 of a gram and and is a reel floter.

Seriously, I have heard that the Saito 72 is a perfect combo for the UCD 46 or put on a quality 2 stroker such as the OS 50. Why buy a Porsche and put your old Geo motor in it?
I have a UCD 60 and power it with a Saito 100 using an APC 16-4W prop. Hovers are around 1/2 throttle and unlimited vertical is not a problem although accellerating through a series of snaps on a vertical upline out of a hover are beyond the engine's thrust capabilities. (I have seen this done with a 40% Edge powered by a 3W150 and it is very impressive!)
