Hi David,
I have built a third scale Balsa USA Stearman using a 250 Moki engine. The Moki is very powerful and does add useful weight to balance the model on the suggested CG which is on line with the upper wings rear strut connection point, no additional weight was required. The torque effect of the Moki is very strong and mine does require side thrust and modicum of down thrust. Hope this is of some help.
