Agree on everything said here about wingtip weights,not a good idea,I doubt whether you will need very much sidethrust really,could you incorporate the motor into a tube of some kind that could be slightly adjusted and then permanently fixed when you have sorted out the thrustline for your model ? my own D.7 had downthrust but no sidethrust with a small 15 size motor she pulled away with a slight turn but nothing drastic,I know tha any thrust adjustments tend to look untidy inside a radial type cowl but subtle adjustments are hardly noticeable.
Being a parasol with a noticeanble pendulum effect about its axis unfortunately the D.8 does need some downthrust,you could assist things with a trailing edge strip of wood a few inches long to counteract any turning tendencies,but lay off the weighted wing idea,a recipe for disaster.
Hope that you get it sorted.
