RE: What planes are your Diesels in?
Just finished my diesel speed model
Nelson 15 D is the power plant.
Prop is one of Stu Sherlocks Q21 single blade props very much reduced in area and diameter
Model is based on a few asymmetric designs.
Basswood wing with bagged carbon (needed to stiffen it up)
Has done just over the 200 KPH but have some things to try to push it a bit faster
