soldering servo wires to rx pins?

I bought some very light stuff from Hobby King to make a flight pack. I have a Berg like receiver making it the heaviest component of the flight pack. The servos have the wrong ends on them so I was thinking o soldering the servo wires directly to the receiver pins to lose the weight of the connectors. . Is this OK to do? Will the heat from the soldering damage the Rx? Any tips? RCNutt

While Your at it. Why not desolder the pins from the RX too and solder the wires directly to the pcb? not much harder but saves some weight

Looking for a tiny rx

I soldered the servo wires directly to the pins and everything is working. What I would really like is a micro rx that doesn't cost an arm and a leg. I have a standard 72 mhz Tx. My rx is big and clunky next to my other airborne flight pack parts. Any suggestions? RCNutt

I do not suggest soldering servo wires to rx, unless ~0.5 gr gain is important for you.

The reason I soldered onto the pins was that the servos came with the wrong ends on them. So I had to do the soldering anyhow and come up with some Futaba servo ends. It was easier and it is a tiny bit lighter as a bonus. RCNutt

Certainly Do able if somewhat Hill Billy :-)
It can get a bit fiddly in there when soldering and the subsequent adequate removal of solder on those Rx pins may preclude using connecters again. Ain't no free lunch.. ever :-)
But remember that The Berg uses Chips and that Means NO Soldering guns only Pencils
Dunno that one can? find a 72mhz Rx lighter than a Castle Berg. Mine measure 3.7 gms
Even newest 2.4hz chip Rx's are in the 3 gm range.
What I've Finally ! realized is that Models have a rather Nasty trend to always Smaller.
Invariably a step or 2 beyond whatever Avionics one currently owns.. regardless of just how tiny it was.. last week..
Pick a size that your gear is small enough for (likely a 3" Bigger wingspan, than the current Hot Topic model size).. And Relax.

I have several of the ZX Technology 4 channels Rx(72 Mhz)and they work fine, they come with jst servo connectors (S,Gnd and V+ order,same as Plantraco servo Rx). BP Hobbies still has the 6 channels version:

As well as a few other places(ZX Tech. no longer exist!)

Consider converting to 2.4 DSM?

LemonRx has a 1.4g, 6 ch (no pin) Rx for $6.

Full LemonRx line.
