I've been looking for this kit for a long time, finally found one on eBay, received it today. Looking over the plans & instructions, I see the designer says the model does not have a lot of rudder authority. The examples he offers of how to use rudder are dramatically less than what I am accustomed to flying (and I'm not big on 3D!). Ordinarily I would have no hesitation to modify a design, but this model seems to be hallowed with a grand consensus as one of the all-time great, highly evolved designs--at least among those that have built and flown it--so I thought it might be good to seek advice before meddling with a proven winner. I'm just wondering if anybody with experience on this model can offer any insights pro or con on adding some rudder area, perhaps using some of the vertical stab as aerodynamic counterbalance. Comments on other aspects of building/flying this plane are also invited.
