Phil,
If this is the RM jr for a .19, 34" span, 19 3/8" long.
Plans show a cg range from the front of the 3/16" sq spar doubler to the rear of the 3/16" spar.
ie cg range is 3/8"
send note if you need more/clearer info.

Roger, I don't have the plans and the wing is covered with $kote so I can't tell where the doubler is.  Can you give it to me in terms of distance from the LE?

Thanx, Phil

Phil.
Sorry for late reply.
Fore/aft cg range, measured from the leading edge of wing is as follows:

Most Fwd position: 1 11/16" aft of leading edge
Most rearward position: 2 1/16" aft of leading edge

Check your e-mail for two photo's from the plans I have.
Hope this answers your question.
