OK, I have a 4 Star 64 that has been flown 3 seasons as my "beater", and it's held up well. Mine has a 15cc gas engine, and the horizontal stab has not been a problem.
Yes, the throttle will be on the right (pilots perspective) with a 2 stroke glow engine. After mounting the engine, you then mark the firewall and drill a hole for the throttle pushrod inline with the throttle arm.
A good place for the receiver is on the servo tray, right in front of the elevator and rudder servo. Today's receivers weigh so little that they have negligible affect on the CG of the plane.
The receiver battery location is determined by how the plane balances. Mine was nose heavy due to the heavier gas engine and ignition module, so it's mounted just behind the wing to balance the plane. Your setup will more likely balance with the battery up in the fuel tank compartment. You just got to experiment with battery placement to get the plane to balance correctly.
The 4 Star 64 is a great flying plane, so enjoy.
My 4 Star 64 was preceded by an old 4 Star 60 that's expiration date came due
The 4 Star 60 is a "build" the 4 Star 64 ARF is assembled
