HI Kaz, no you still balance the model where it says, a little bit of tail weight is far better than a heap of nose weight ...the test for incidence on the wing is to go to full power and trim the plane to fly level ...now cut the power... if the plane pitches nose up...too much downthrust...if the plane pitches nose down...(very rare) too much up thrust ...(this is all with the CG in the right place, also determined by elevator sensitivity)...if the plane doesnt pitch, but sinks fast as it slows, this means high wing loading ...use up trim to slow the decent..but not to stalling speed(tip stall)
far better to move the engine forward and have a little nose heavy, than to add a lot of nose weight, use wot you got.....these damm orientals always get something wrong.
