Hey guys,
I'm looking to soon reduce my excess inventory and I am wondering what is the value of some older transmitters? (By older I mean ones that I no longer use).

Taigen V1 2.4GHZ (No button on the upper right)
Torro versions of the above
Heng Long 2.4 GHZ (RX18 version)
Heng Long 27MHz Senders w/o Crystals

It's worth what someone is willing to pay for it....
I think a complete set in good conditions up to $ 20

What about just transmitters? (I've burnt out my share of MFU's LOL).
