DA or BME 100
Ahem ..BACK to the original subject. . .
Either the BME102 Evo or the DA100 would be great engines for the Suk. If you build heavy, then the DA would be preferable sicne you will wind up needing more nose weight. If you build light, and take care to use rudder pull-pull and mount the batteries forward in the fuselage, then the BME would be preferable. By losing well over a pound of weight with the BME, and getting the weight out of the tail as much as possible, you would have a faster reacting, better flying plane than with the DA, no matter the power difference between the two engines. Everything the plane will do in the air, from snaps to rolls and 3D, will be improbved by minimizing nose and tail weight. this can only be accomplished by removing as much engine weight as possible, then setting up the tail contolrs, radio gear and servo locations to minimize the tail weight. Overrotattions and tails wagging around are caused by mass and weight back there, and are not effectively damped by the engine at the other end.
My advice. . Get the BME, get the tail light enough to establish a proper CG without adding ballast in the cowl area, lighten the plane 1.5+ pounds on top of it, and have a better overall flying plane that reacts better to control inputs, is still tremendously overpowered, and has a much beter damped tail at the end of snaps and hard 3Dmaneuvers.
Hope this helps
