Default Many Planes..Few Receivers

Sounds like a movie but the title says it all. I'm sure many folks are trying to be prudent with how many receivers are actually needed day-to-day.

My question for the forum is:

Given an assumption that it is not much fun connecting servos up each time to you want to fly... and...

Given the BEST solution is at least one receiver for each aircraft....

If I swap one receiver between two planes regularly, will I cause extreme wear and tear to my connections at the receiver?

Thanks in advance for pondering!

You can get away with it for a little while, but, do yourself a favor and buy 1 receiver every month for 10 years LOL ,then you will have all the receivers you will ever need LOL , OK OK maybe for 10 months Take care and have fun, Chellie

I may be getting Older, But I Refuse to grow Up I am Having to much Fun to Grow Up LOL

Very little damage to the receivers, unless using other brand servos which have smaller, thus very tight, sockets in the plugs than the pins on the receiver.
Whilst the typical S-01 utility plugs look similar, the actual male/female pins/sockets do vary quite markedly, especially with cheaper other brand leads.
Have had several Futaba RX in for service where one or more pins have become loose and pushed through the board - cause of many at the time unexplained jitters. The main problem is with again the use of other brand servos with ill fitting female connectors (inside the male plug) which expand and become loose after many plug/unplug sessions. Watch closely for any one lead backing out of the housing instead of engaging on the pin, especially battery packs, another regular cause of unexplained "lost it" calls.

The other thought is using extensions for each receiver connection. But I more agree with Chillie - buy more. It is sure nice to grab and fly.

With HK and others selling clone Rx's cheap you should be able to stock up for a reasonable amount.

Interesting - you can afford many planes, but somehow not the RX.
Just saying......

fly
If you're going to learn to fly them, you have to learn to fix them.

I like that idea, then I can buy a plane to go with each receiver, huh? LOL

Seriously, the consensus seems to be buy what you need, and need what you buy. I just wish the sales would coincide with the needs, Ha!

Thanks Alan! I'm a regular visitor to your website and that's good information to ponder. We do a lot of pondering in Texas, LOL.

I am looking into that possibility but haven't built up confidence in those receivers yet. Might be a good time to start.

Oh I certainly get it......put your $$$ where it will do the most good.

Budgeting for planes is my one weakness, just don't do the same for the electronics.

And then there's the quest for the "best deal" on price.

Thanks!

Heck---how many of you guys remember the day that you only had ONE
transmitter and ONE receiver, and ONE battery pack, and four or five servos.

Then you had to switch EVERYTHING from plane to plane.

Helicopters don't really fly.......
They're just so ugly, that the earth repels them.

Default Santa Was Generous

Hope everyone had a wonderful Christmas!

Santa was helpful in seeing that I have enough receivers for my existing fleet AND an extra one, woohoo!

Happy flying into the New Year...

If I swap one receiver between two planes regularly, will I cause extreme wear and tear to my connections at the receiver?

Thanks in advance for pondering!
From what I can determine, the better receivers are using gold plated contacts. Even though that gold plating is microscopically thin, it does do the job.

A concern though, is the receiver circuit board that the servo pins are soldered to. If that circuit board is single sided copper foil, you only have the thin copper foil pattern available to solder those pins to. And these connections are subject to being broken when those terminals are flexed very slightly repeatedly. Something I found out during many years of troubleshooting bad designs at work before retiring. Solder has little mechanical strength.

A far better design is the use of double sided copper foil on the circuit board. These double sided circuit boards use plated through holes between the top and bottom copper foil patterns. So, when you solder a pin to these double sided circuit boards, solder flows into the top copper foil and the bottom copper foil. The solder also flows into the plated through hole, filling it full of solder. Trying to break a solder connection here, will likely break the circuit board itself.

As for my five Spektrum AR7000 receivers, they use double sided circuit boards with plated through holes.
