Thanks beat Ching and your info is helpful. Btw, can I use the Futaba S-FHSS system matched with the receiver which is not a Futaba's product? Sometime I'll purchase aircrafts from the Taobao site and hope it will be matched directly.
I have read some notes about the two RC systems (FASST and FHSS) In Futaba product. The FASST system provide with a higher reliability system than the FHSS system, especially in flighting environment. Should I invested RC control in FASST system rather than FHSS of my first aircraft? It would be much appreciate to get your help in which band, model and system is the best buy now in Hong Kong?
