I can see how the randomness would be a problem for air models.... A player who sets up an airplane model design and then waits six turns for it to finish would be irate if the design came out with an operational range of zero hexes.

Feels weird for engine design score to have no relevance for aircraft at all.
For me too...
Going back to real world aircraft; in their design and production there is no question that engine characteristics are of paramount importance. The storied Rolls-Royce Merlin engine, for example, was crucial for making the Spitfire MkI and II such an effective fighter, and subsequent iterations of the Spitfire were arguably just iterations of the engine.
In game, I personally also wish for those design columns (engine, armour, weapon design) to have greater or more varied and structured effects, in more cases. But it also seems like the total cumulative overall effect of the entire 'Model Design' mechanic has a limited 'importance' budget or range of possible magnitudes, and that its maximum effect is equal to about one tier of technology and is usually much less (if that makes sense). So, no matter how deeply the sub-systems in Model Design are developed and deepened, they would not necessarily affect the overall game much.
alas.
But back to engines in planes, which is the part I find interesting.
Based on my extensive knowledge from watching television, I would like to point out that the real world has a suggestion to make regarding this game problem: Engines, or power plants, are developed seperately from the airframe, to given specifications. Then the same engine is used in multiple aircraft designs, and the aircraft will be designed around the engine, or the expectation of the engine, ensuring the aircraft will be able at least to take off.
So one way to recover the importance of engine design in SE Air would be separate the 'whole aircraft design' from the 'power plant design', with the latter happening first.

There's actually a pretty interesting story about this massive pancake piston engine partially developed by Germany during WWII to power their next-generation fighters and bombers. Except that the engine was fundamentally too big to engineer successfully, and consequently a whole generation of aircraft-in-design were lost, stalling the technological evolution of the entire Luftwaffe.
