2.4 rx

[Diamond Geezer]

Hi guys

should I wrap my 2.4 rx some at the club say yes others say no what’s your opinions please.

[Frank Skilbeck]

Wrap it in what?

 

In my electric models and gliders I just mount them with velcro, for my IC models I put them in foam (unless the receiver has soft mounts)

[Diamond Geezer]

Thx

             With 2.4 rx's I was told that they should not be wrapped in foam or bubble wrap as they produce more heat [for their small size] than old 35 type's.

        Not sure how true this is but have velcro pad mounted all mine both IC and electric.

see what I mean you Don’t butFrank does I don’t know what to do.

[ken anderson.]

the crack was,they do generate more heat,so in electric...no wrap,ic wrap in loose foam

I don't wrap mine, bind light being the reason, in old days they were big lumps and had inertia in a crash, not so much now being tiny and I don't crash. ?

Thanks

Tempting fate or what !?

Yep. ?

If your receivers have built in gyros/stability they will need to be mounted securely using double sided dense foam tape. Otherwise Velcro is a good option.

That was the case with some very early 2.4 receivers, from Futaba I think, but the problem only arose in warmer climates where there was a big cockpit letting the sun heat the model internally.

 

From Multiplex's receiver installation notes - "Protect your receiver from vibration, especially in models powered by internal combustion engine (e.g. pack it loosely in foam)" they make no mention of making sure it doesn't overheat. 

 

Just checked Futaba's instructions for their R3008SB and they specifically mention protecting the receiver from vibration "The R3008SB receiver should be protected from vibration by foam rubber, Velcro or similar mounting methods. Protect from moisture" again no mention of overheating.

 

So basically do what ever your manufacturer instructs.

Receivers are very different these days. Earlier ones had larger components atop wobbly legs which could fracture through vibration or impacts, often ripping out chunks of copper tracks as they attempted to get further into the crash than the PCB. Modern surface mount components have much smaller mass and are soldered directly to theIr PCBs. 

 

Given space, on both IC and electric models, I like to clip them into 3D printed mounts which I either foam or Velcro mount to the fuselage structures. 
 

P.S. I’ve just remembered that the advice not to foam wrap receivers seemed to stem from some reports of Futaba receivers overheating in the early days of 2.4 GHz where the models were being left in direct sun in 100+ degree temperatures in the southern USA.
