Wow, is your name Andrew or Hard Way Harry? I scratch built my first jet but I left the engine building business to the experts. I do fly with a friend who built his own KJ66 though, great engine. Strangely I picked a similar configuration for my jet which is also balsa/ply/foam & weighs about the same..

I struggled with oleos & grass strips for a while before changing to simple wire legs. Bending 1/4 in piano wire into coils was a challenge (step 1, make a bender) but it solved all my problems.

Yep, absolutely!! Congratulations! - John.
