i really doubt it
best bet would be to buy the ship again

No, you cannot reattach engines once you unmount them. FL only recognizes a ship as needing one engine, not more than one. So, yes, the only way is to buy the ship again.
But there is not a limit to the number of engines you carry. You can carry 5 different engines in your hold if you want, them mount/unmount them (one at a time) at will.

JUST OUT!

You can remount the engines, but you would have to use Alcander's sellable engine patch.

I'll check that out with Sirex and see how it works.

By the way... Ro9ue, would you send me an up-to-date version of SirEx (via Sendthisfile, unless it's under 10 meg).

The version that I have is probably a tad out of date

Talk to you all later,

Ah, heya bro

Crap, I'm checking this as I am about to leave for California for 10 days. I would be more than glad to send you a nice update -- complete with some new ships, new icons for all equipment and ships in the game, custom cockpit models, .dds textures, and .... *drumroll * custom weapon models W00t, yeah, I said new weapon models. Oh man, words just don't express the excitement I had to punch the air for a few minutes because the wall would be too noisy (at 4 am, with parents asleep ).

Anyways, yes, you are in for an uber update However, I can't send it to you right now. Hmm, I can try to call my sister and have her email you ... Well, that is a definite maybe, though it'll probably have to wait until I get back (July 6th) Dang, sorry, but I will try to walk my sis through it sometime in the next few days. But I can't make promises about that. So I'll mail it to you for sure on the 6th - rather, upload it for you via SendThisFile - it's about 43 MB right now, with another batch of ships coming in from awts0c soon... How 'bout that, will that work? Can ya survive that long, now that I have told you of the goods? I know I'll have a hard time, being away for 10 friggin days .. ay, ok, not tihnking about that right now.

Anyways, I have to beat it here, so I' will talk to you guys later. Brian, I'll try to get the file to you ASAP. And since I'll be gone for the day, happy 4th of Juky everyone

For now, Ro9ue out.
