Ok...first thing I have a Kadet LT-40 with an OS 46 LA....good combination for that plane, although keep in mind that engine is no powerhouse for a next plane.
Have a JR 631, hubby has JR 431....basic difference is mine has dual rates. Both are good computerized radios and will be good for many planes to come. And as far as the wife...hhhmmm...kick her to the curb (J/K).....at my house I kick hubby outta the basement 'cause I'm building and last one to the flying field is a rotten egg (that's usually him)
