I've posted this issue some time ago. IMHO R4Ms needs some adjustments. Check when it's fired, it goes down, not like others ones that goes almost straight. A link bellow show that it has been set to 8° upward. Here are more info about air rockets: http://www.vectorsite.net/twbomb6.html Nice pictures. http://www.answers.com/topic/r4m-rocket Include Pierre Clostermann info and has more interesting links. http://www.stormbirds.net/tech_r4m_rocket.htm (with pictures) "The launchers were aimed with a slight upward angle of 8 degrees. When the rockets were fired from a range of 600 meters, they had the same ballistics as the Mk 108 cannons. The warhead was a 55 mm HE shell filled with Hexogen. A single hit was all that was needed to bring down a four engined bomber." More pictures: http://home.att.net/~jv44/r4m.htm http://www.warbirdsresourcegroup.org/LRG/r4m.html
R4Ms are going down. Just go to TA type alt+V, adjust view to beside plane and fire. You can compare the diferent release angle of all rockets in different planes. For exemple in Fw190F8 R4Ms shuld go 8° up not ±15° down as can be showed.
