ive got a fs 120 os on mine and it flies really nice powers through anything boar a hole in the sky hovers 1/2 throttle full throttle go unlimited i normally fly 60cc gassers and this plane and engine combo works well together i had a evolution 100 on it and it sucked, i took this fs 120 i had off of my cap 232 and put it on here and with a apc 15x6 and 15 % nitro 4 stroke cool power fuel its great a little nose heavy still working on that when i have time, can pull full up and wont snap, great harrier plane. make sure your plane is balanced not just cg but ballanced as seeing which wingtip is heaver bc with the 120 on it if its mounted horizontally your right side from behind the model will be heaviest so you will add weight to the opposite wing to correct this. its better to correct it on the ground than to trim it out in the air. let me know how it goes.
