I'm not sure if you are aware, but the mod doesn't seem to account for atmospheric drag (Or it just doesn't agree with FAR which changes how drag works). I have a very large jet with 4 turbojet engines and a small jet with 1 basic jet engine. Due to it only seeming to try and match the T/W ratio the big jet's thrust was limited, and it couldn't reach a suitable takeoff speed, while the small jet humorously slammed into the big one at high speed while on the runway destroying them both (The small jet reaches like 700 mph at sea level it's ridiculous). Otherwise it seems to work great for anything outside the atmosphere, which definitely leads to some fun rocket fleet moments. It does co-operate when the crafts in atmosphere are exactly identical though, as shown in the videos provided.
