Default RE: World Models Ultimate 40S

i got one of these planes about 3 weeks ago , took me about 10 hrs or so to get it ready to fly, like many others i did not like the idea of a micro servo running four ailerons so i used a futaba s3004, took it to the field for its maiden, and ran into a problem the servo did not seem to want to give me much throw in my ailerons, after some fooling around i realized i did not glue the rods that connect the lower ailerons together, so i did this with some thin CA, that helped a bit, but was still pretty much having the same problem on further investigation i figured out the ailerons were real stiff, i took it home and worked them up and down like crazy, but still no joy so to remedy my problem i cut a bigger hole in the wing and turned the servo so that it was length ways across the cord then added a second servo right beside it i know this added a lil bit of weight but aileron problem solved.


as far as the overall build it was pretty straight forward the jigs to align the wings was great, unlike the above post all my predrilled holes lined up nicely, and i loved the clear cowling with that i probably made my best looking cowling ever as far as cutting it out around the engine, i opted for mounting the engine on its side just because i do not like sticking my hands underneath a running plane especially one that sits that low. once it was complete i checked the CG and it was right on i mounted the reciever next to the fuel tank, and the battery near the firewall on top of the tank in the opening there my setup is

servos: 5 futaba s3004 (2 aileron 1x rudder 1x elevator, 1 x throttle
RX: Futaba Par 2 4ch
TX: Futaba 7cap
engine: O.S. 55 AX
Battery: Futaba 1500mah

the plane flies great, has enormous amounts of power with that .55, its pretty fast, and pretty touchy on the controls even with the suggested throws, T/O is a lil touchy with all that power it wants to roll from the torque, flight is nice once you get comfortable with the controls, it doesn't like to land.....lol our field is surrounded by trees by the time i get low enough you almost half to force it down, cuz it gains alot of speed on the decent.
