I'm New Here
On numerous trips now with maximum luggage, I’ve found my RV7 to be very close If not right on the aft C of G when landing with less than say 50% fuel on board. Replacing my Sensenich metal fixed pitch prop with a Hartzell constant speed prop would be the obvious solution but unfortunately I’m not in a position to do this at the moment.
As it’s a reasonably light build with plenty of gross weight margin, I’m considering installing a crush plate forward of the front spinner plate to alleviate the aft CG situation. Saber Manufacturing can supply a 7 inch diameter 1 3/8” plate that weighs 15 pounds which is fairly close to the difference between a FP and CS prop. What is also required is to swap the currently installed 2 1/4” spacer with a 2 1/4” prop extension as there is a maximum bolt length that Saber can supply.
Has anyone tried such a solution for aft CG on an RV7 with a metal prop ? Or does anyone see any issues in doing this ?
Thanks,
