Is the M14P much heavier than the Lyc?
———————– The M14P FWF is about 60-70lb heavier I think. I know the M14P FWF is 50lb lighter than a 220hp cont radial like on a stearman. The P&W R985 FWF is about 300lb heavier than the M14P. The R985’s extra 90hp is not much gain over the M14P for an added 300 pounds. It makes the airplane a single place that is very big on the front end, since you have to keep the same gross wt so that gives you a 450-500lb useful. A better choice is to use the M14PF of 400-420hp with no weight gain. BTW, the 300lb added weight of the R985 comes with a thrust gain of only 200lb over the 360hp M14P.
