CG vs prop

Well Known Member
Building an RV7 with Lyc 0-360, no mods. Will wood prop have a negative effect on CG? I've heard the 7 tends to be a bit tail heavy, yet lots are flown with wood/composite pros. Talking fixed pitch here. Any experiences appreciated,
Thanks, Jim
 
Heavy crush plate

One way to move the empty CG forward is with a heavy crush plate.
http://www.sabermfg.com/ makes a setup like this for RVs. My heavy crush plate measured just shy of 20 lbs.
You will need the 12 hole extension from them, also.
This mod moved my empty CG about 1 inch forward.
(1.16? from 72.03 to 70.87 on my RV6; the Datum may be different on the RV7,
but the change will be similar)
