RE: U-Can-Do 3d 46?
The Fun 50 needs one less servo on the elevators and therefore needs no servo reverse Y-harness. It does not require more expensive ball bearing servos ... standard servos work fine. It comes with much better, heavier push rods so there is no need to spend money on upgrades. The weight difference leads to the ability to fly great 3D with a smaller, less expensive engine. The Fun 50 has an airfoiled ... flying ... tail section for better stall stunts. I have never heard of anyone having damaged wing ribs on a Fun 50 straight out of the box. It balances perfectly when built to specs. Its wire landing gear means you dont have to beaf up the LG block and add weight.
By the time you add the costs of servo upgrades, the extra servo for the elevator, the reversing Y-harness, push rod upgrades, cost of a bigger engine and add in the worry factor of "when will my wing break?" or "when will the landing gear fail?", you will see the Fun 50 is, in my opinion, a better way to go.
