New Tx/Rx time

[lordnikon]

In the market for a new Tx and Rx, currently have a GT3B which is fundamentally the same as an Ansmann W6.

I've noticed some lag with it and it has the dreaded 'no expo' buggy firmware too.

Options ...

1. Spektrum Dx3C + additional receiver (2 models)
2. Upgrade the GT3B firmware + new servo with spare $$
3. Sell some more car gear and get a KO PRopo / Futaba

I have an Alturn digital servo at the moment and it seems ok, read some mixed reviews on the spektrum re: range etc. Upgrading the FW on the GT3B has also seen mixed reviews so not sure ..... any opinions
