I'm talking about the P-6E Hawk. On page 30 of the manual it states they needed 16oz of nose weight using the recommended O.S. 1.20 4-stroke engine [].
This plane screams for a gasser . I don't know what the cowl demensions are yet; but that's why I am also looking at one of the new high performance 30's like the RCS or MVVS engines. They definitely will fit. Of course, if you wanted to spend the money, a Laser 160 or 200v would fit [X(]
