Other alternatives:
Airtronics RD6000 or RD 8000 can handle both planes and helis, and multiple setups.. easy to program
Hitec Eclipse 7 with Spectra module also can handle planes and helis and with the spectra it can use different channels (frecuencies) so it may help if he has multiple channels in his other planes
P.S. what do your other husbands do...
just kidding
