I once had a fun week playing Kerbal Space Program building solar-powered quadcopter launch platforms...
Basically a quadcopter which is mostly a big platform with a rocket payload in the middle. The quadcopter slowly ascends to the highest feasible altitude, bypassing all of the worst of the air resistance, and greatly reducing the delta v needed to get into orbit as a result.
This was mainly helping with the atmospheric drag problem, though; you would presumably need a lot of atmosphere to get far enough from the planet to help with the increased need for horizontal speed with a super massive planet.
Not a rocket scientist or even a physicist.. but if i remember right, the bulk of your energy in a rocket is expended on your horizontal speed not the height gain. I came across this when I was looking up if it made sense to launch a rocket from an equatorial mountain like Kilimanjaro (6000m asl)
Keep in mind that KSP happens in "easy mode" where all of the atmospheric drag, gravity pulling, and orbital speed are smaller, but they are smaller by completely non-proportional amounts.
Last time I looked, there was a mod that made Kerbin like Earth. I suggest you try it.
Sadly, once you lose focus on a craft in atmosphere it is lost. So shortly after you start piloting the launched probe, the quadcopter gets garbage collected by Kerbin's atmosphere.

Oh hey I found an old screenshot: https://imgur.io/zq8iyV0?r
