    Subject: 685 vs. Aerostar
    From: "stratobee" <adam@adamfrisch.com>
    Here we go again.. :D As I look ahead for my future flying and something to grow into, once again my thoughts come back to the 685. I've read Milt Concannon's summary about it and how he thinks it's just a little bit misunderstood. My work takes me all over the US, and I'd love to be able to fly myself there when it's feasible and weather permits. I'd ideally need all weather capability, long range and pressurization. Especially long range. I'd kind of set my sights on Ted Smiths's other design, the Aerostar as a good step up. In fact, I came very close to buying an immaculate one about 6 months ago, but couldn't quite make the finances work in time. But as I look at the 685's for sale just sitting there month in and month out and not moving - prices keep going down - I couldn't help but start comparing the two again. A 685 can be had for about the same price as an Aerostar, give or take. PROS OF 685: 1. Now, what's good about the 685 is that it has many of the things I want already built in. First of all it's a Commander, but secondly it has insane range, full de-ice and all that good stuff. Stuff that I'd have to add on the Aerostar most likely, at least the aux fuel tank to get comparable range. That's a $15000 modification just for the aux tank. Most of them don't have full certification for icing, but can be upgraded for another $10K or something. It adds up. 2. The other "advantage", if one may say so is that a 685 would probably able to land at a smooth grass field or a dirt strip without shedding a leg, whereas the Aerostar would probably not. I realize none of them are particularly well suited for backcountry flying, but if there's a choice the 685 is probably better at it. 3. The Aerostar has a racy wing and won't tolerate you going slow, so even though it's 3000lbs lighter, you'll use the same amount of rwy and touch down at the same speed. None of them are short field performers. The Aerostar has a life limit on most of it's windows (just below 5000hrs) and the front wind shield is about $20K. I'm assuming the 685 has no such vices? CONS OF 685: 1. The Aerostar is probably the most economical twin for fuel one can fly. 25gph at LOP and 190-200kts. That's hard to beat. I'm assuming the 685, leaned to within an inch of its life, would struggle to get below 35-38gph at speeds around 180-190kts. On a long cross country that's a difference of about 100gal.. 2. The Aerostar has "normal" engines and none of that funny stuff. That said, my geared engines have not given me undue trouble and I know of quite a few people who fly geared and have little problems. However, the 685's is the most highly strung of the geared engines and I've heard that a couple of cylinders will pop each year. Just how it is. And should they need an overhaul, we're talking $50K/pop. Phew. 3. The Aerostar is also fully supported, whereas I'm assuming the 685 is probably not. 4. I also fly predominantly alone or with few passengers - do I really need to lug around 9000lbs of airplane for one person? Seems a bit irresponsible almost... Who the most reliable is mechanically is probably also a draw. I'm assuming they'll see the equal amount of insides of hangars. Good thing is that I know a lot more people that can give good advice in the Commander community than I do in Aerostars.
