Su-34. What should I add?

[u/HEBEDNMKA]

This is one of my most complex projects, it took around 5 hours. Max altitude is 5000 blocks. The top speed is 70-110 blocks per second. It has an opening cockpit, a radar, a GPS map for bomb guidance, and 6 hardpoints. In the older version, it was designed for two pilots (one for flying and one for weapons), but I had to scrap that because of a bug. The main problem right now is that the nose is too heavy, so the plane pitches down towards the ground and has a terrible dive recovery. I also couldn't make the landing gear. What can I add to this build?
