I'm asking those that built The Proctor Nieuport 11, Do you think the Saito R19 3 cylinder would be too much for this plane?.

From a Laser 80, 690 g, the R19 is 1205 with muffler and ignition (950 g engine only)

The prop size and range are similar, 13x9 to 15 x 6.

Did anybody have to add weight to balance? I'm wondering if going from 7.5 lbs. to 8 .5 lbs. due to engine weight would be a problem.
