That is all. There is nothing more to this simple build.
As a summary, the purpose of this build is to see if it can be used as a baseline for the jet version. To that end, I enlarged NOBI's model which was stated as 1/48 scale by 145% to 1/33. However, when I measure the final model, it fell short of the desired scale by approximately another 15%. So the original is not really 1/48 scale.
The model is too simple to enlarge to 1/33 accurately. It requires more sections and specifically a better way to attach the twin booms to the wings. Also, it is lacking landing gear bays and interior cockpit, so that has to be considered as part of a redesign.
Looking forward to see Murph's version of the jet J21R.
