Umm, which OS 90???

[syn-]

Ok, so it looks like there are FOUR different types of 90 size heli engines produced by OS. Which one would be the best bet for good power with relatively low complexity of setup? Is there one that is just far and above the preferred engine?

- Engine list -
* .91 SZ-H PH-Hyper
* .91 SX-H Ring C Spec
* .91 SZ-H Ringed
* .91 SX-H Ring C Spec w/Pump


Or am I just going the wrong way all together? Should I be looking to YS instead?

Thanks guys,

I have the SZH(pumped) and love it, very powerful and smooth. There are only two SZH's, one is pumped and one is non-pumped. Don't know much about the C specs. Might as well get the SZH as it looks like it will probably replace the C spec. Can't go wrong with that YS either! :arggg:
