I fly my stock FJ with a Mega 16/15/2, 6X3 apc prop, 4s lipo, and it is not only fast, but will go vertical, way faster than the "speed" FJ's, and is very docile on manuvering & landing! 6X3 doesn't sound like much pitch, but behind the Mega motor, on 4s is AWESOME FOR VERTICAL...Try it, you won't be disapointed....Paul
Paul, how hot is the Mega getting with that setup? I have a couple in S400 pylon planes with 4.1x4.1 APCs on 3S and they get toasty.
