For $600k, I'd much rather have a real turboprop.

Aw crap.....where did I put that winning lottery ticket

There are pics on the Barnstormers ad. Search Harpoon.

I've wanted one of these for a long time and I think they only made 2 pressurized Harpoons. I like everything about this airplane other than the price as there are too many other options including Eclipse Jets, Citations, King Airs, Meridians, Silver Eagles, etc. depending on how much fuel you want to burn.

I'd be very cautious about buying anything right now with a Walter or GE engine. Apparently, there is a rather ominous AD in the works that appears to much of the world as an attempt by GE to sunset the Walters by making them economically unfeasible to keep airworthy.

Why would you spend this much money to go 210kts? A straight Malibu will do it for a lot less in up front and recurring costs while sporting a bigger cabin. From what I have observed, the Allison engines are not exactly pt6-like in reliability.

That said, cool looking plane beech should have made.

Hey guys, Steve here (Seller).

As with everything in life, it is all about the compromise. I couldn't find anything that would do 200kts, burn JetA, pressurized and carry 2500lbs. AC and FIKI(sort of) were just bonuses. Of course, it doesn't do 260kts, or burn 60gph. But it also has better avionics, less required mx, simple insurance, easy training etc. I am honestly not completely set on selling it. If you look at FA, I use it all the time and it fits my mission (carrying heavy stuff around the western US!). Honestly, I might be drinking too much of the MU2 coolaid and have convinced myself that doubling my operating expense would be a good idea!

I haven't heard anything about a GE AD. Not sure how they could put an AD out on a Walter engine that they didn't make. Regardless, it's not the plane for everybody, but it has (and still does) worked great for me! A malibu or SE210 isn't ever going to carry 1500lbs in the cabin and still go 500mi with reserves.

I have figured my OPEX is about $450 an hour at 150 hours a year.($8k insurance, $8-10k MX, $4k hanger(could be less), 40gph block@$4 a gallon average, $30 engine/prop reserve. That works out to <$400 an hour.

There are "real" turboprops out there, but not for this operating cost. It is really so nice to be sitting at FL210, burning 38gph, doing 210ish, with flip flops and shorts on.

BTW, yesterday with 6 adults, at only 17,000 I had 105kt TW, new GS record for me, 312 kts!!!!

Here are a bunch of pictures. https://goo.gl/photos/FSRHu6wNoi5JV4m97

This one is not an Allison, but a Walter 601 which is pretty much a clone of a PT6A from behind the iron curtain.

That is one cool looking bird!

Well, GE doesn't issue ADs, the FAA does, but GE is involved because they bought the company and own the rights to the engine. They have upgraded it to the GE H80 series and their version is caught up as well. Right now there is a fairly large stink going on in the agricultural community since Thrush is apparently the world's only OEM for the H80 engines and 100% of the GE engines affected are going to be in that group. Right now the NAAA convention is just getting started and I expect to hear a lot about this issue shortly.

Congratulations on owning a super cool airplane by the way. I sure wish that Beech had covered the skies with them back in the 70s and 80s so they would be an affordable option for many of us today.

They own the Type Certificate, so they can issue a SB that could prompt an AD.

I don't think ADs apply to experimental airplanes but I could be wrong. I'm slightly surprised the Walter Harpoon doesn't go closer to 250kts. Doesn't the B36 Rocket Turbine go close to 250kts?

I think it might, but this is a 6200lb aircraft. The A36 conversions are about 2000lbs lighter. It is weight dependent. When I have been light, at altitude 220+ was never really an issue. There is alot of structure in the 58's that the 36's didn't have, then throw in the pressure structure. It's all about the flip flops and no O2 bottle!

Plus, I have a feeling that the tip tanks, and short wing hurts when it is heavy. Fitting in a standard T hanger is nice, but an extra 8' of wing would probably help at altitude. This plane really likes 17-22,000.

------------------------------
By letter of the law, E-AB's don't need to comply with AD's. If there was a stupid AD that came out, it would be worth a discussion. I have always complied, even when not required. Example, I replaced the wing bolts, even though they looked great and that was only a SB! This isn't a Kitfox, I put my family in it and fly anywhere and want to trust it.

6200lbs and short wings - what's the stall speed?

Slightly above a brick?
