Looking for a 120 four stroke 3D plane, try the World Models 120 3D arf. I bough one a couple of months ago and put my old OS 120 on it, flew great until the header pipe blew out, so bought a new G2300 Supertigre on it, and it goes ballistic. Gotta exercise allot of throttle management with the 1.4 Cu.in. two stroke on it, but with an APC 18X6W prop, it flies great slow, hovers, knife edges, ...etc. Currently practicing IMAC pattern with it, since it flies slow, but like a pattern plane, easy to do stall turns, straight rolls, and so forth. Huge wing, thick foil, very light wing loading and two piece plug in wings for easy transport. I took off the spring landing gear, installed a floor with 1/4 ply and put a 4 star 120 landing gear, since I fly at a really rough, bumpy, uneven grass field most of the time. IT comes in two colors, I have the green, which has allot of yellow with it, so easy to see. It comes with split flaps, so you can set up crow with four servos for ailerons, you'll need an 8 or 9 channel radio to use this feature. if you use a six channel, then your stuck using y-cables on each wing, but have the advantage of two seperate servos for the large ailerons. I used an 8 channel futaba PCM receiver, with channels 1 & 6 on ailerons and the two auxiliary channels slaved to them using channel 7 & 8. I used a reversing y cable for the two elevator servos and a 6 volt 1650 NIMH battery and super switch. All the servos are heavy duty (77 oz. torgue) except the pull-pull rudder, which is a digital MG 155 oz. I've got about 20 plus flights on it and fly the Imac pattern with no real mixing issues, the plane is so neutral and stable. The 3D stuff is great, but much slower and more graceful than my U-Can-Do .46.
Hope this helps a little, good luck on your search. Let me know if you find anything better.
Happy Landings,
