easy one this!

Open up the p47 in ops...

copy the bits attached to the prop, and the smokerleft and right, and paste them onto the geebee!

Make sure you aren't flying the Beta release where the breaking dof's dont work though. The system works by having an object with an airfoil attached to the prop. It is joined by a dof which breaks easily. The dof breaks, detaching the part, which triggers a small explosion positioned where the exhausts are.

job done!

Thanks, do I paste it in OPS in the properties window?

Hawk, I think what tail means is that you copy the part in OPS off the '47 and highlight the prop on your GeeBee and hit paste. The new airfoils and DOFs should then appear as children of the GeeBee's prop.

Would this change my original prop? I mean would the size and pitch and airfoil for the prop I am now using be altered?

Hawk, when you do a paste operation on any part in OPS, you're not replacing the original part, just adding children to it.

That is, say you had a part called "Prop". You copy a part from another sm file called "Airfoil" or something. Then you select "Prop" in your sm file and paste. The "Airfoil" part will be added as a child of "Prop" and the properties of "Prop" won't be changed at all, it will just have a child called "Airfoil".

I copied the engine start from the P47 and pasted it to my prop. I then copied the text pertaining to the smoke from the properties and pasted it to my properties and I get the explosion noise but no smoke so far.

Are you seeing any visual explosion effects at all? If you're getting the sound, there definitely is an explosion happening, maybe the smoke and related visual effects are really happening, but its origin is 'inside' the fuselage, or blocked by another part or something? Also check the explosion size values, maybe the explosion is too small to see. Just an idea.

The explosion isn't very big. Wherever you pasted on the smokerleft and right should be where the smoke comes from. You probably won't see it from inside the plane.

I added this feature to the B17 a while back, but the smoke produced was too small for my liking.

I have seen the real thing in operation, and the clouds of smoke produced were pretty big! Stands to reason really. Any radial engine is going to have oil seepage past the rings etc. on the upside down pots, and when they fire up, this will burn off. Used to get exactly the same effect on a VW Beetle I had if you parked on a steeply cambered road!

Snickers has suggested something which I might try, adding multiple smokers for each cylinder. Have to be careful though, since if you get too big an explosion, the plane might get damaged!

Wouldn't it be possible to increase the visual explosion size slightly and leave the actual explosion force value alone, and have a larger smoke effects for the '17?
