Chinooker,

According to what I've seen here, I wouldn't dare putting an MDS into a quite detailed warbird... I believe u when u say yours are fine, but apparently many encounter problems... I would rather trust the .65 LA, with no problem, but I will no longer put my Euros in OS engines (I own a .20FP, a .46SF, a .91VRDF, all excellent engines, but things have changed...). Today, there ARE real alternative solutions. Let's take this opportunity to question OS superiority and to discover other brands ! My favourites are : Irvine .72, TT .61, Magnum .91. The latter would turn this warbird into a missile IMHO...
