AS in moving from one plane to another?

I have a spektrum 6200 in my glow trainer and I'm buying a multiplex easy glider today.

I'll eventually but another 6200 RX for the glider but putting it all on one bill may be a bit of a shock to the wife....if ya know what I mean ;-)


Is it bad to move the RX from plane to plane for a week or two?

Also do you think I could get away with one of the lesser park flyer RX's? I'm using a DX6i TX


Thanks

Steve
