....i dont think thats it,sounds more like the me163,the r4m sound is more like"pffft!'
anyone have a idea where to look?

That IS the sound, it only sounds higher because of the over-rated doppler effect our game has.

I know for a FACT that the Me-163 uses different sound files because I have redone the rocket engine sounds, myself.

All rocket weapons such as Tiny Tims, X-4, R4M, RS-32, HVAR, etc. will ALL use the rocket_06 sound file.

All AIRCRAFT rocket sounds for Me-163, MXY-7, BI-1 and BI-6 use the following four files.
engine_3_65
engine_3_71a
engine_3_71b
engine_3_72a
