I beleve the O5 was Hitec's attempt to escape the bad press from the origninal Feather single conversion rx which of course seems to have been a disater for Hitec. I also beleve they were reasonably successful doing so however I do beleve those Rx's are not up to the standards of their DC products. I have witnessed a case of a out of range flyaway as well as experianced one myself flying a students airplane with that Rx. Can I prove it was in fact a range problem or related? No of course not and that could never be proven. However I don,t seem to have the same problem with the very large number of 555's, Electron 6's and various Supremes I most often use.

Specifically concerning the JR SC rx's, Yes this a different case and it is well known they use a proprietory filtering system (for lack of a better word) that they call ABC&W or some such and it seems to work satisfactorily. It does seem notible however that all their newer Rx's seem to now be DC

There also apparently is another filtering (agine maybe not the best word but useful for this thought) method used by possibly a few of the small companys and that I cannot address.

Because of the variouos points above I do not buy into the arguement that DC/SC conversion type cannot be used as a indicater for Rx performance. I beleve of course it can if you educate your self to some exceptions that do indeed exist such as the JR SC Rx's and maybe a couple of others.

So for me beleve it or not Hitec remains my favored product in 72MHz systems and has been my favorite since they were Aristocraft. And specifically the 555 (discontinued), Electron 6 and various Supremes. It also helps that Hitec customer service is legendary and I have seen none of the majors or makes of the past ever have such excellent service.

I only have three electrics out of a large number of glow aircraft (I am completly unable to keep any kind of count) and the very tiny Electron 6 does a wonderful job in those.

All of the above is nothing more than just my personal opinion based on my personal experiances.
