I have started this kit and was eager to follow Peter (apart of engines...), as he had much more references than me. And I experienced the same problem: You can not fit a decent IP into the cockpit. You have to make the instruments much smaller - no way to use the proper Aircale photoetched fairings... I tried very hard, sanding nearly through the wall od the front part of the cockpit, but still not enough. I stalled the build and must say the Hornet from HPH is pretty complicated to built into decent kit. But I plan to restart it sometimes.
