radial engines

[avbug]

TD,

The spark advance is only applicable to some engines. Same for leaning. I usually used the autolean setting on the carb, as long range economy was never my primary goal. Also, it wasn't often in those airplanes that I'd stay in cruise.

100LL tends to foul plugs badly; forever chasing dying or fouled spark plugs due to leading. On the P2V-7's, the leaded fuel tended to build up on the turbine blades, too (R-3350's, J-34 on same wing).

when leaning for long cruise, I usually set up either lean or rich of peak, but usually didn't advance back to get power per the traditional method. I also leaned often by the color of the flame on the shortstacks.

Flew the right seat on a '-6 awhile ago.

I came in one early morning into St. Domingo some time back, with that still air basically flying the ship for me. That right base to final on a visual, where the captain isn't on your case for once for not being nuts on the 'slope, and she just slid right onto the runway.

I still remember that afterglow from that greaser that warmed up that early morning cool. We taxied off to the cargo ramp passing an American Airlines jet along the way.

That heavy crew's waves were the icing on the cake. I've never felt so proud in my life before or since.

Thanks for the update guys, brings back a lot of memories.

A Squared,

Are you running ADI fluid for the takeoffs, or just keeping those overall limitations for detonation prevention?

Another radial fan...

My 1st consumer dream is a DC-3, 2nd plane would be an Albatross. I have this "thing" for radials, that makes me turn into a little kid and run out of meetings if i hear one outside. The sound goes straight to the heart.

I use to work by Opalocka airport couple years back, and they got this enormous assortment of radial stuff: tons of DC-3s, Super 3s, DC-6, DC-4, DC-7 (the only operational one in the world!) and lots of Convairs, not to mentions twin-beech's.
Just the other, day though, I took a spin around there and seemed like half the planes that were flyin back then were either mothballed or torn apart. The times, they are a changin...

And from what it sounds they spend more time in the hands of a mechanic than the pilot.

Avbug,

Yeah, We're using ADI on all our heavy and/or short takeoffs. Otherwise we'd be limited to 87,600 Lb for takeoff.

Hey crash-proof: What kind of motor do you have on that gooney? The prop is turning backward! (Or maybe it's just my computer)

 

[crash-proof]

It's built for the europeian market!

Naw...actually somebody already commented on that and I'm just too busy (lazy) to turn it the right way.
Good obs. though...

 

[Tri-holer]

Yeah but if you notice, the Goony bird is sucking up the exhaust which explains the prop rotating backwards. When the crew gets out, they'll have less time than when they started.

 

[avbug]

Crashproof,

It's not the only DC-7 left operational; there are a few remaining.

Round engines (or any large recip, for that matter)

Originally posted by avbug Is the sound worth it? . . . .

When you're in the house and you hear the sound and without thinking you run outside and look up to see what's flying, you bet it is!

We do have some T-6 buffs who like to fly formation from time to time on Saturday and Sunday mornings. My favorite, though, is the summer before last when I was in town running an errand and heard what sounded like a T-6 formation. I looked up - and it was a beautiful B-17! I heard the same thing the next morning (Saturday) at home. I looked up. It was the B-17 - again!

Just saw a beautiful Connie on the miitary ramp at KEF.

update...

Just happened to be in the Tamiaimi part of miami yesterday and decided to shoot by the airport. Saw an A-26, Super 3, and a Catalina! I think they all belong to kermit weeks, not sure though.
Somebody told me they saw a messerschmidt 262 take off from there. Are there actual flying examples of these???

And here's a nice site on buffet's albatross (can't stand buffet but he's gotta nice plane!!!)

[flywithastick]

seem to recall reading somewhere that there are some full-scale replica Me-262's being built to fly. Not too many originals around and I believe they're staying in museums.

 

[Tri-holer]

Been awhile since I read the article but from what I remember - A builder took a ME-262 that needed work from a museum (I think a Naval museum) and arranged to fix what needed fixing in exchange for being able to reverse engineer the airplane and is building a total of 4 or 6. They will have J-85s inside a Jumo engine shell and I would presume modern avionics but would otherwise be exact replicas. Haven't heard much lately.
