I would be surprised that the goal of the Ho 229 project was to produce a stealth fighter. I assume that the Germans knew that wood makes a plane less visible on the radar, but I don't think they knew alot about stealth shapes. The Ho 229 has a very aerodynamic profile, so I think that the designers wanted to build a streamlined fighter. And I think that the Germans were forced to use wood, as wood was easier to produce than aluminium.
After I have written this, I see on wikipedia that the goal was to produce a streamlined fighter.

Wouldn't bailing out from a Ho 229 be very dangerous? The engines are on the sides of the cockpit, so if you bail out the exhaust gasses will burn you!
