Here are the servos Iwill be using
(4) JRPS821 for rudder, elevator and 2 for the ailerons
(1) JRPS791 Main gear retract servo
(1) JSP20080 Nose gear retract servo
Ijust weighed my plane in 3 pieces (Wings, Fuselage (with motor and ESC) and batteries and servos (in a bag)and it came out to about 10.6 lbs (Remember Ihave 8cell 5000 maHbatteries). but this does not inclued a seperate RXbattery pack, but Ithink it will come out ot aout 150 watts per pound or somewhere close, which should give me plenty of power based on rule of thumb!
Tell your son Isay hi and ask him if he has any flying tips
