Kevin,
We don't need no stinking RV-4 dimensions. Do this. More details are
on the URL http://vincesrocket.com/finishing.htm
1) make the wing fit the fuselage. The limiting item will likely be the
edge distance at the rear spar bolt holes.
2) ignore whether the fuselage is level. It doesn't really matter.
Really, don't sweat it whatsoever. Well, OK make it somewhat level from
left to right so that your Diet Coke doesn't slide off, but fore and aft
isn't important.
3) level the wings to match the specs given i.e The data I have from
Mark tells me to set the rear spar height 2.95" lower than the main spar
when the fuselage is level. (Except don't worry about the fuselage
being level.)
4) set the HS to Set the incidence on the HS using a 1/8" spacer on the
front spar and a 13/32" spacer on the rear spar.
5) marvel at your genius. Mine flies straight. Yours should also.
Here's a tip that I think that you will like very much if you have the
gumption to do it now...
Ignore the instructions that say to put the VS on straight. Why? How
many RVs or Rockets have you seen that DON'T have a rudder trim tab?
Not very many I'll bet. And they are always on the left side of the
rudder aren't they?
Well, mine doesn't have a rudder trim tab! I mounted my VS on crooked.
OH MY! Yeah, well it works better that way. Mount the rear VS spar as
usual but mount the front spar so that the LE of the VS is about 3/8" to
the LEFT of the fuselage centerline. =20
Yes, that will make your store bought tail fairing not fit... but it
won't anyway. They never do. Make your own and save time and money.
Have fun.

I am fitting my wings to the fuselage, (HR II) does anybody have a
dimension for the wing incidence? Can't find anything on this in the
vintage RV-4 plans I have.=20
Thanks,
Kevin Shannon
