[1.7 Maneuvering Engine Balance Changes]

With KSP you have the choice not to upgrade (at least for that playthrough).  KSP allows multiple installs with different versions and different mods ... just download the .zip and install in a different directory.  Say 1.4.x, 1.5.x, 1.6.x, 1.7.x under a KSP directory.

You can also mod (copy) in the old engine values into the newest version.  You may not play a vanilla 1.7 but you can continue using your career and ships with no surprises.  (See above on multiple installs, too.)

Or you can convert to 1.7 and adapt.  Your in-game crafts will not be affected: their parts and part stats are stored in the savegame. The new engine stats will only affect new craft (launch pad or runway or similarly spawning into the world --- just being on rails does not put them out of the world).

Thanks for your efforts, writing down all this.

The point ist just.. I didn't execute most of what I have laying around here based the Spark.

And doing it in something else than the most recent version is like failing or cheating to me. I don't like making things easier than they are stock.

Some time ago I have even dropped my Single Stage to everywhere Grand Tour (a real one, not one of these "*except here and there"), which was almost completely recorded, when they released 1.2 with Eve's changed Atmosphere which destroyed my Eve SSTO....

You can stress that more than it's worth...

Most people were not really aware and generally use engines one or two sizes to big for their crafts, and I also ignored this engine for long, but it was the most outstanding allround engine for small to medium crafts in the game.

Its asl twr was verry high. Only surpassed by the biggest launcher engines: mammoth, vector, skipper and mainsail.

Its vac Isp looks not the best on the paper, but due to its verry low weight and still high Isp and thrust, it surpassed the supposedly best vac engines terrier and poodle on most crafts, giving them up to a decent size more dV on the same amount of fuel than these two. (and even way more when you fill up the saved weight with fuel)

It's low weight and low fuel needs  also makes launch vehicles verry small.

This combination made it the perfect and op allround engine for small to medium crafts, working as high efficient transfer and lander engine even for atm at the same time.

And that's just a small selection.

No huge change so not a problem.

30% more weight for the Spark and even 33,3% worse asl twr is verry huge  this kills all designs based on the old specs.

Sadly, after this update my little lowtech 1-junos SSTO can't reach the orbit... 

 

And several other little SSTO too.

actually all my small crafts amongst some records holders have stopped working… i also can throw my actual reusable career playthrough attempt into the trash can, ob which i have worked for more than 6 month… 

all those designs were based on the spark, just because it was definitely overpowered and out of balance
