Micro reciever for 60 size extra?
 

i have a extra 300s with a OS YS90, basically it came with a hitek reciever from the guy i boght it from, which is not compatible with my jr radio, so i got a jr micro reciever 6 channel FM. works perfect, but i just read the instructions and it says to only put them in gliders, parkflyers, and 30 size nitros. how the heck does a reciever know the difference between a 30 and a 90?

The micro receiver probably has limited range compared to a standard JR receiver.

vibration ......

I'm new to this but i would think the biggest problem would power draw. the micro recievers would be designed to handle smaller servos, which means less amps. I imagine a stantard servo pulls more amps and so the reciever has to be able to handle it, just like there are different size contollers for electric motors.

Chicken,
I'm not sure about JR but Hitec does not recommend their 555, micro, receiver for fuel use.
The reason is a daughter board soldered to the main board. It is not designed to handle the vibtrations of a fuel plane.
Good Luck,

No HiTec advertisement for all the years this receiver was in production ever limited the 555 to non-wet power use. And the HiTec service department never cautioned me about this. Perhaps you have some other model receiver in mind like the Feather? And come think of it, HiTec never had any objection to using the earlier 535 receivers with piston engines, either.

Dsegal,
Hitec adds were for its use in electrics.
You are correct, they never said not to use it in fuel planes.
This info was given to me by their tech when I was in having one checked after a strange crash in my glow plane.
Others have used them with no problem.
I'm just passing on what I was told.
I'm not going to risk another plane on one of these receivers.
Save them for electrics - what they were designed for.
Just my opinion and philosophy.

The 555 is perfectly suitable for use in any application including glow and gas. If you were told that it was for electric only then the rep was mistaken. The performance of the 555, Electron 6 and Supreme dual conversion receivers are essentially the same. :)

The Idea that the 555 cannot be used in glow/gas aircraft or had reduced range is patently absurd.

That Rx was in fact my favorite of all time. I own around twenty three and after the last purchase was disappointed to discover that they were discontinued. I own only one electric. Almost all are use in glow airplanes and airplanes the exceed speeds of 165 mph with forty size engines that routinely exceed 20,000 RPM. That is an extremely harsh vibration environment And the 555 performed and survived better than most other so called standard Rx's from a variety of manufactures.

I can only make the following statement:

You can runoff with my wife-
You can steal my money-
But you better stay the -ell away from my 555's
