Hi JohnnyMac18. I worked at high altitudes in Nepal for a number of years, but not using a drone. Bad Andy’s advice about not forgetting your own performance at altitude can’t be stressed enough.
I’ve witnessed many tourists suffer altitude sickness to varying degrees. I’m sure you already know the three bits of advice if you feel unwell: “descend, descend, descend”. It’s shocking how many people ignore this, even after prior reading.
Mental processing is easily affected at high altitudes. It’s actually common. Keep well hydrated and don’t drink alcohol for 24 hours before or whilst at altitude as this will make the problem worse.
I know this point is off-topic, but please make sure you get the best possible advice for malaria prevention before travelling. I had very bad malaria for 17 years, and still get lesser attacks now, because I only got advice from a good GP. A medical clinic I established and managed for 25 years saw 5,000 malaria patients every year. Treatment and prevention is getting harder because of increasingly resistance, and sometimes you need certain medication based on specific regional advice rather than national advice. I don’t know where you are, but contact a hospital specialising in tropical medicine in your capital city for the latest/best advice because malaria kills a huge number of people every year.
This final point is also off topic. My wife was apparently one of the two first women to travel most of the way round the world on a motorbike many years ago, including where you’re going. She would like to remind you to make sure your horn works well, as it’s essential for safety on those passes.
