you can get some serious speed up with the air intake bug.  The hardest part is staying out of orbit (that and avoiding firey death through overheating)

Updated to 1.19.1.1, what happened to beam core accepting thermal engines?  Is that a permanent change or a bug?  Bang goes my micro antimatter spaceplanes and their 1m beam core powered ramjets

 

Also same issue as ss8913 - I wasnt paying too much attention but actually forgot to switch fuel at 24k as I usually do.  Was very surprised to find I was on a kerbol orbital trajectory at 70km.....  That being said, I also dont have a heat spike when first powering on the thermal engines - this was a major issue and pretty much killed my thermal craft previously so that bug has been fixed.
