I've been thinking about getting a 90, probably a Rapter but I have been looking at the Gohbee Stinger also. I can fly decent but I am not really big into the 3D yet. Can anyone recommend which 90 size engine to get for one of these two helis??

The YS is a great engine and I use them a lot. I also run the OS 91's and if you are doing a lot of hard 3D then the OS is probably the better way to go. Not that the YS won't but you have to have a lot more collective timing to keep them from bogging. As for tuning, unless you have the OS with the Kline reg the YS is a lot easier to tune and keep tuned.
