Suppressor

I did some tests with your dev version and I must admit, you know your tech.. congratz.. after 3 or 4 launches my stock Kerbal X got into a 80km Orbit with 3286m/s of DeltaV left. it went there slowly and in a ball of fire.. but it's as efficient as it can be. Edit: I did some testing.. and, since I'm trying to improve my rockets and all that I noticed sometimes I change it too much and the addon will get nuts thinking I'm still using the previous version that it has all its data from. (I could rename it, ofc) Is it possible to add a "clear custom data" button or something? (I know I can just delete the data from the addon folder, but that would be quicker.

I'm having the same issue as you two. on my stock career I'm having to make a decision, go back to 1.2.1 or modify all my launchers. (So far I'm back to 1.2.1) I'm used to set it to 60s to AP and it always worked just fine for me, a mixture of low fuel usage to low time to orbit but with 1.2.2+ (I only tested 1.2.3 but since it was on 1.2.2 that he changed something about TWR I think it started there) my rocket begins the gravity turn then it tries to go back a little and hold a pattern close to vertical, it's nothing big and I noticed it's more pronounced when I input something bigger than 40s on time to AP. I ran quite a few simulations and I noticed I lost around 200 m/s DeltaV from 1.2.1 to 1.2.3 with the same rocket and same settings (I'm talking about Kerbal X in case anyone want to reproduce the testing) What I did was: add mechjeb to Kerbal X rocket, just that, launch the rocket, click best guess then either launch with Time to AP as 40 or change it to 60 on both start and end. Below are a few of my results: 1.2.1 - 40s to AP - Total Burn 3094, Total Loss 1035, orbit DeltaV remaining 3220m/s 1.2.1 - 60s to AP - Total Burn 3086, Total Loss 1056, orbit DeltaV remaining 3197m/s 1.2.3 - 40s to AP - Total Burn 3163, Total Loss 1101, orbit DeltaV remaining 3156m/s 1.2.3 - 60s to AP - Total Burn 3047, Total Loss 1243, orbit DeltaV remaining 3008m/s I made some other settings, like 40s/50s to AP (works great and 1 to 2m less Time to Orbit) and 40s/60s to AP (not as good on the fuel side but better than straight 60s) TL;DR - From 1.2.1 to 1.2.2+ my crafts lost DeltaV with best guess settings or best guess + 60s to AP. It's more pronounced with 60s to AP. Any Suggestions? The issue seems to be with this thing the rocket does at the start at the begin of the gravity turn.
