We were doing some research for the Arrow upgrade this weekend and we just can't make the average C33A/E/F33A work with the loadout of our family and our upgrade desires (2+1+ton-o-bags, with the front pax seat unoccupied). The 35s gives the wife airsickness and I refuse to babysit the pedals (what's next, downgrade to carb heat?! LOL). Beyond frustrating, since we love the Bo cruise numbers, but eye opening to see a piddly Arrow do a better job at a 540# payload mission than a Bo.
What you need to understand about CG is that shift range is not as important a metric as you think it is. This is because it is the shift behavior of the aircraft as it loses fuel that matters most. Then and only then does CG range become a metric of consequence. In the case of the 33/35 Bos, what I discovered is that at least for the 33s, the empty weight CG location is already too far aft. Combine that with the aft-shifting trend of the Bo due to the tanks being significantly forward of the EW CG, and you are then likely to fall aft of the CG when light weight even though you took off legally when heavy. If you have a backseat/bag centric mission like mine, it's a non-starter. The V tails are lighter on the tail so the CG is a bit forward vice the 33s, so they're slightly better on that front. Still no cigar for me. The search continues. The A36 works for me though on the balance front, but then I looked at current prices, and walked away from the entire thought exercise. LOL
The comanche doesn't have that problem. It is a standard piper in that the tanks are pretty aft of the EW CG, which means the CG shifts forward. That lends itself to a more pax friendly loadout. The volumetrics in the comanche imo are slightly more comfortable on the width, at the expense of the headroom which is inferior imo; Bos are steeples in comparison.
Again, I don't consider a 225 IO470 Debbie a peer of the comanche 250/260 series, I lump those with the Arrow and the comanche 180. Frankly, stock debbies are pigs. C33A would be the only one one of the straight tails that would be somewhat comparable. In reality, what you need to be comparing Comanches 250/260s to are N-P 35 Bos with the 260 IO470. That's the peer benchmark imo.
