Default just to make sure...

heya guys...i have read this before here but have not been in rc for a bit so have lost touch!

a)what shift are futaba receivers on? and do they go with hitec or airtronics?

Futaba work with hitech receivers. Dual conversion has nothing to do with the Shift..

Hitec and Futaba are negative shift although some of their transmitters can be programmed to transmitt on either shift. JR and Airtronics are positive shift.
Dual conversion has nothing to do with high or low channels, it is the method in which the receiver decodes the information transmitted from the transmitter. Dual conversion converts the frequency twice, first to about 11.7 MHZ then again to 455KHZ. single conversion just immediately converts the frequency to 455KHZ before amplifieing and decodeing. Each method has its advantages and dissadvantages and can be equaly good or bad. You will find good receivers using either technique.
