Hi Guys - Rudder / fludder question. In comparison to the PL and ZN kits I've built and flown, the Impact fuselage is much stiffer. The PL/ZN stuff as you know has the kevlar fibers aft of the wing area and to the tail, where as the Impact has the TAVs construction. The PL and ZN kits have one horizontal and one vertical support in the aft section, just as the IMPACT has now been corrected to incorporate due to the rudder/fludder problems.

I'm about to add this new vertical former and horizontal piece as the CARF drawings depict. My observation is that if the much more flexible PL/ZN stuff have basically this same stab supports, then it should be more than adequate on the Impact give that the fuse starts off much stiffer than the PL/ZN stuff. Thus, why are so many adding full tail-moment supports? Does the TAV construction react differently than the Kevlar PL/ZN fuses? I'm going electric and need to come in on the lighter side of construction.

My rudder weight is 66 grams.
Thanks,
Jim W.
