I put a 3W 100 in mine hovers at 6 clicks above an idle. Take off go to knife edge as soon as wing will clear runway at 1/4 throttle
with the heavier 3W I had to add just 6oz of tail weight to get the aft CG needed for 3D fight . With the BME or the DA you are looking at adding 1 to 2lbs of lead in the nose or moving all radio equipment as far forward as possible plus having the fuel tank forward of the CG or wing tube my tank is right over the CG location This all boils down to persanal preference do you want a Chevy or a Ford? After all you are in the drivers seat when it is all over and done with!!!!
