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.

One other thing to add when buying a plane, and in my case is service. Tower Hobbies is awesome when it comes to replacing anything. When I called them and told them my wing broke, 72 hours later I had a brand new in the box complete UCANDO. When I told them I landed my UCANDO in tall grass and ripped the elevator off I had a new elevator within 48 hours. So it's not always the plane you buy, but who you buy it from. I would spend $150 on Towers site for new UCANDO rather then take my chances for $100 on Ebay without receipt or warranty.
The UCANDO is a UCANDO, it flies great, the Fun 50 is a Fun 50 and I'm sure it flies fine. However if I was looking for another plane to buy like the Fun 50 I would just do a RCU thread search. One has nothing to do with the other. Christ, we could sit here all day and debate which 3D plane is better then the other and why, but who gives a sh**. Unless of course you are a salesman for Fun 50's. Or the other reason could be you accidently bought a Fun 50 and now regret and trying to convince yourself that it's the better plane.
UCANDO's RULE. One of the best $150 bills you can spend on a plane. Service alone is worth twice that. It may need some beefing up on the landing gear block, control horns or whatever. I would also rather have an extra servo on the elevator, and I also added another to the rudder on mine, and I bet it hits harder then the Fun 50. Balanced perfectly with no weight on mine with Magnum 80 4S.
I get nothing but ooohhh's and aashhh's when a spectator watches me touch the tail. It's a very pretty plane that can excel ANY new pilot fast.
In my opinion and I am sure in most other in this thread, the UCANDO rocks and is no better or no worst then any other 3D plane. It is what it is.
