Just a thought, shouldn't the 2x2x1 have more than 4x (even if just slightly) range than the 1x1x1? Because otherwise, why wouldn't you just use 4x 1x1x1s and have a total range of 400km? - Last I remember, range for jump drives was additive - maybe this is no longer the case?

k thanks for the info I'll keep that in mind for my next build

Its based on Weight, as all the jump drives are ( even Keens vanilla drives ) if your ships weight is heavier than optimal for the drive, the range reduces....

I love the little changes to the jump drive...but I like to give a heads up on something. I built the 280km jump drive for my new small block ship but when I go into control panel of the ship and click the jump drive the distance slide bar says 100% 139km is this the right jump distance for a small block ship or should it be 280km like the jump drive says....just wondering.

I reproduced your issue, Jump option doesnt appear when you are attempting to put JUMP onto your bar via a group, but from individual drive its fine. This is a Keen-ism.

there is a jump option, i can not reproduce your issue

There's no "Jump" option for these. Could you fix that?

That's all I'm asking. If it's ridiculously difficult that's fine, the mod is already an Improvement over the vanilla jump drive.

I will think about it, there is a ships max weight balance in the equation ( its a function line in the mod ) already

I'm saying the 3x3x2 small grid jump drive should travel less than the 1x1x1 large grid jump drive.
For instance:
Large Grid: 3x3x2 = 1250km, 3x2x1= 480km, 2x2x1= 280km, 1x1x1= 100km
Small Grid: 3x3x2= 80km, 3x2x1= 50km, 2x2x1=30km, 1x1x1=10km

This mod already contains both large and small block.

Have you tried to tier the small grid jump drives to continue the trend? That way small grids don't go as far as the large grids.

Nice! :D
