Alas I am moving and getting out of the hobby but selling my DevoF12E with 4mb chip installed and working perfectly with the latest XMS Deviation firmware installed as well as an extra F12E which is all working for replacement parts (the Board on the spare F12E is no-good) but all else works. As well as a DevoRX1202 and a DevoRX802 receivers. Asking $230 and will figure out shipping if a buyer is interested in USA or other countries.
