Hmmm it may have been an issue with OpenGL and mach effects, just tested on dx11 and the frame drop is muuuuuuch less pronounced. I think I'm going to put it down to an unrelated game engine issue. Indeed they are. I did notice sparks on vessel load but didn't put 2 and 2 together. All engines are stuck with a thrust limit of 1 when reloaded. As long as its a known issue I'm content to just keep working around it in-game for now

Awesome! It works incredibly well up until 208m/s where my frame rate starts tanking. Limiting the thrust to <200 eliminates the issue. Also tested with the stock lift only rocket engine VTOL (+a couple extra engines) and it didn't seem to be affected at all, however I wasn't able to reach the same speeds to test if the framerate tanked in that setup. If you would like me to do some other specific tests just let me know I did notice another bug while testing this relating to returning to a previously landed craft (from space centre or vessel swapping when in range) with TCA enabled, where TCA cannot take control of the engines. I have to turn off TCA, get my engines working manually by throttling up, then turn TCA back on again to engage it. Cheers

Ah right, that clears things up a lot, thanks! I think that aft-engines are already working very well at the beginning and end of the flight as they are used for acceleration and braking as required, its only in the long haul between distant targets that it really becomes apparent. By then its generally pointed in the right direction thought so I just set it to cruise or hover and throttle up. Seeing that this strategy is working for me for now I'll just keep truckin, but it would be great to see it go full speed on auto and leave my pc while my convoy ships goods around Thanks for all of your hard work, seeing what your mod does as it balances thrust reaffirms my belief that it would be impossible for me to fly VTOLs without it

This mod is fantastic, makes flying the USI Honeybadger an absolute breeze, (in formation too!). Cheers for all the hard work I have a question - well, more of an observation and possible bug report/feature request - about the cruise control and waypoint autopilot: no matter what I set the horizontal speed limit to or how severely I pitch forward (that is how to tell TCA to go faster in these modes, yes?), my atmo craft never seem to reach anything near the speed I can achieve by using 'level' 'hover' mode for my main lift engines (the honeybadger electric prop VTOL engine in balanced thrust mode) and manual engine control for rear thrusters (stock jets, the best ones). The autopilots do use the manual engines to bring it up to speed from a standstill so I know it is taking them into account, but I'm getting ~40m/s to 250m/s+ much slower acceleration compared using manual thrust control or CC (while TCA keeps me fixed vertically, which is brilliant!). I can temporarily up the speed by pitching forward, which engages the manual engines as I assume it is supposed to, but the system always ends up drifting back down to a slower pace fairly quickly. Cruise control works as expected with pitching forward to increase thrust output (I must have misremembered that), but 'goto' and 'follow route' seem to suffer from a severe case of moving like a tortoise when they could be going full steam. I guess I'm just not sure how this lift and thrust system is supposed to work for TCA (I don't think my craft is non-standard from the others I've seen on the honeybadger and onther VTOL threads, like this one). It seems like a bug, or maybe something that hasn't been implemented yet, or maybe a speed sanity check that I want to ignore... because keeping my massive flying bricks in the sky in formation, with manual thrust control is spot on. If you need a demonstration I'd be happy to put up a video or something, unfortunately I've lost the craft file so it may take some time to put it back together I put it back together. EDIT: I went back with the remade craft and checked a few things, seems my memory was a bit wrong as to what was happening: Cruise control works fine but there is still very slow acceleration issue with the waypoint autopilot.
