From the assembly manual:
2.2.2 Aerobatic Maneuvers
Aerobatic maneuvers are permitted within the following limitations:
Aircraft weight not to exceed 2000 lbs, G limits are +6/-3
Aft C of G limit not to exceed 97.4” aft of datum (where datum is 80” fwd of wing leading edge)
The text in bold is a typo or other editing error that crept into the manual previously. There is NO way that those 2 statements are correct when stated together. The aircraft gross weight is 2000 lbs, but at that weight the +6/-3 is NOT correct. Please keep reading.
The Harmon and Team Rocket wings are based upon the RV-4 wing, which has a 23' wing span. The Rocket wing is shorter, with a total span of 21' 10" or about 14" less than the RV-4. However, the Rocket's slightly wider fuselage means that the wing panels are even shorter on the Rocket, by almost a foot per wing (when you exclude the center section).
The same number of ribs are used, with slightly tighter spacing. The tighter rib spacing reduces skin oil canning a small amount, but does not appreciably increase the strength of the wing.
However, the shorter wing results in a stiffer wing in bending. In addition, the shorter wing also uses .032" skins along the entire span, if the builder used the optional one piece skins, as most did. The .032" skins helps marginally in bending, but also results in a torsionally stiffer wing.
Team Rocket supports John Harmon's statement, as mentioned by Danny Melnik in the post above, that
aerobatic weight should not exceed 1550 Lbs. At this weight, we recommend +5/-3 G. The lower weight is not only for wing spar considerations, but is also to minimize inertial loads on the tail and fuselage, and to have a more consistent pitch response.
Furthermore, the laws of physics are true and inflexible. Doing acro with a passenger moves the CG aft. An aft CG has a large effect on stick forces in a bad way. It is all too easy to pull far more G than expected with an aft CG. In other words, stick force per G is very low. A very light pull can result in a large G load. Aft CG is detrimental to spin recovery also.
So, unless you and your passenger are horse race jockeys, there is no acceptable way to do dual acro in a Rocket. And don't forget that parachutes are also required, and so is fuel. Dual acro simply isn't feasible or recommended.
Team Rocket recommends solo aerobatics only, and only after proper training has been received. What Mark Swaney said above about aerobatics is spot on. However, the manual entry claiming a 2000 lb gross weight and +6/-3 Gs is incorrect and should be removed from any POH, builder's manual, or any other document, that you may have.
