OK... I have the bug quite bad now for flying the P2... But I need some more granularity and confidence in the TX unit controls. (for filming)... So, I'm looking at getting a Futaba of some sort. Therein lies the question(s). I'd like to get the least expensive one that can control the Zen gimbal. Do I need to mod the P2 Rx or other electronics? I'd rather not... Any input appreciated.... ..
