Get a good set of 3-views and a Kadet Senior kit. Not much change needed to make the Senior into a Tri-Pacer.

(I think appx 1/5 scale...)
The fuselage is a bit long... and the tailplanes are not quite the right shape. Add the struts and a little reshape of the carved cowl....
Just reshaping the tailplanes and adding struts, its a good stand-off scale Tri-Pacer.
