Pre-takeoff checklist
I thought the S and T models also have anti-corrosion and some noise reduction treatment, plus the fuel injected engine.I was in your shoes 2 years ago . I knew I wanted a 182 but wasn’t sure what model I really wanted. After a ton of research I decided I wanted a P or Q model. The S and T models (I’ve flown several ) have nicer interior when stock. But that’s really the only upside in my opinion. The P and Q models typically have quite a bit more useful load. You can get a purely paper STC (fresh picks STC) that increases your takeoff weight by 150 lbs. There are plenty of other STCs available for them too. My plane has a Pponk engine which is basically a O470 transformed to a O520. It’s somewhere between 260 and 285 hp depending on who you ask. Either way it’s a serious upgrade in power. I don’t think you will be disappointed with any 182. Any one of them will definitely meet your mission requirements. Your biggest problem will be finding one before it’s already sold! They sell fast! Like same day the listing go’s up fast. It took me 6 months of trying before I found my plane. I got lucky and found it before it got listed. That will probably be your best bet. Join some Facebook groups and let everyone know you are in the market and what you want. Someone just might message you that they are thinking about selling but haven’t yet. Swoop in as fast as you can! They really do sell that fast.
The fuel injected should allow running GAMI's and then LOP, which provides lower engine temps.
I found a 182P with the Peterseon King Katmai conversion, think that would be my dream, but talk about hard to find.
There is also a 182S Wipaire BOSS conversion with 340HP, but my wife is not approving the price (yet).
