A few months ago I bought a couple of these to see how good they were.

In use they seem to work fine. I'm only trying them in a low value foamie with no non-flyers nearby - just in case, To get a bit of confidence in them, but I'd noticed that on startup the servos jittered somewhat and their travel wasn't smooth. At one point before launch 2 days ago the elevator ceased functioning for 5 seconds.

Errrr. Discretion being the order of the day I packed everything up to investigate later. Today I decided to do said investigation. And all the above problems resurfaced but no worse. I thought it might be a binding issue which I re-did with no change.Then I did a range check and the problems all disappeared! Curious. That got me thinking so with receiver energised and Tx (Aurora) in hand I started to back away from the receiver, twiddling the sticks as I went.

At about 1/2 metre the problems were ever present with some strange behaviour. At about 1 metre the issues were less. At 2 metres the problems had all but disappeared. At 3 metres - no issues whatsoever with smooth output from the servos. Just to say all the above applies to both receivers.

The only conclusion I can come up with is the signal strength from the close proximity of the Tx swamps the receiver causing these problems.

My confidence is now restored. I just have to be aware when doing pre-flight checks and launching solo.

Your thoughts? Has anyone had issues with these alternative receivers for Hitec or other brands?

I don't like using non genuine rx's not worth it, although on foam models it's not as bad, but still.

You're perfectly ok with these, they're Simons receivers. (Simon's a forum member here)
I remember a few posts on RCG saying that they can swamp at very close range but in general use they're fine.

Cheers

I have seen warnings about having Hitec's own receivers too close to the transmitter during binding and to keep them a few feet apart.

From my experience its not just Hitec's thet wont bind at very close range, Spekies sometimesdo it too at, 6' or so away it all works though

Hitec rx`s are cheap enough not to bother with compatible......

And it made me wonder why I bothered! But it was just a trial and I wondered about other's experiences. For an extra 6 quid I could get a genuine Minima. Which reminds me I need to order a couple more Rx's.

Ian sorry for not jumping in here earlier, i fly with my trusted aurora and only use Hitec gear. Though i did trial with that receiver ect and had my elevator (only) shudder and lock up whilst within 1 metre but free up during normal flight. When trialing new aftermarket equipment i always use a cheap foamie glider and this stuff failed. I never gained confidence in it sadly. Though my Optic 6 and Hitec gear works perfect. Maybe a bad batch!? but i'd rather buy genuine for a few £ more than risk an aircraft.
