TX Neck Strap Adapter?

I'm looking for a neck strap adapter that changes the CoG of spread spectrum radios so they will balance correctly. I have a Futaba 12FGA, if that matters. Thanks.

Examples:
Transmitter Balancer "The Transmitter Balancer was designed and precision CNC machined for pilots who utilize a neck strap to stabilize/balance their transmitter during flight operations. The Futaba 12Z and 14MZ originally designed for use with the 72MHz systems now has the FASST 2.4 GHz system modules available. This creates an imbalance due to the shorter antenna length and change in the CG (Center of Gravity). The Transmitter Balancer is adjustable to get the correct balance for your flying style. The Transmitter Balancer will also work with the Futaba 10C, Futaba 7C, Futaba 9C, JR9303, Jr 10X, JR12X, SpektrumDX6 and DX7 transmitters and possibly others."

$2 from WallyWorld. You can pretend it's CNC and cost $20 if it makes you feel better. Looks ghetto. Works perfectly.

Good thinking.
I'm gonna try this on my Futaba T7C, already loaded the inside top with lead but not enough.

Thanks for the Ideas.

A.T., the first one you linked to looks to be the one I need. Thanks.

Shizack....that's a really good idea....however the hook on my transmitter runs vertical, not horizontal. Looks like it works good for the DX7 though. Thanks.

Safety,
It might be possible to strip your TX down, undo the nut that holds the neck strap swivel and rotate it 90 and re-tighten.

Put the 72 MHz back on and extends it!! CG is correct! Cost: ZERO.

It's funny you should say that because my radio came with only the FASST module....and I emailed Futaba about getting a 72mhz module and antenna, and it cost:

HSP78899 72MHZ RF MODUL 14MZ for $99.99
HSP79555 TX ANTENNA FAI10 for $15.92
Shipping $ 9.99
Total $125.90



Definitely not free, but I still might do it though just to have.

Is that how far you have to move the CG to get it to balance
I'd be concerned about the amount of stress you're putting on the mount. That's a lot of leverage there

I like a little forward tilt in my transmitters. Much more comfortable for my old "bass- player" wrists.

I look at the original eye hook and check the case frequently for signs of stress, but nothing yet. I don't rest my hands heavily on top of the TX and it's kind of supported by my pinkies underneath.

If the strap broke (unlikely; it's a padded saxophone strap designed for a MUCH heavier device) the TX wouldn't fall, but the heli might. Besides, the TX isn't THAT heavy to begin with.

No, I just say the antenna, not the 72MHz module. The 12FG I brought was a 72 MHz version and I bought the TM-14 module. So I have the original antenna! Actually the 12FG with tm-14 on it balances pretty well. All you really need is to put a piece of velcro on the bottom of the tx and hook a string to the neck strap with the mating velcro on the end of the string, adjust it so it hangs to your liking.

Yeah, the radio sits halfway decent on its own, but when I put my hands on it the bottom wants to fall down. I might try the string thing tonight. Anyhow, I was saying that I'd like to have the 72mhz module because I sill have some old fm receivers that I could use for small cheap foamies and such.

I tried doing that once to an Airtronics VG400 and found that there's a flat side on the hole of the TX and a corresponding flat on the shaft of the neck strap eye not allowing a 90 degree change. Might on the Spektrum tho.
