Tips on PID tuning / rates for higher elevation (Denver)

Hi all, posting more questions! I’m new to quads but have been flying Helis for a bit. I live in Denver and on my Helis I’ve definitely had to tweak all my RPM and pitch curves to not fly sluggishly. I do all of it on my radio (Taranis running open TX). I got a TinyHawk 2 and on 1s it basically FIGHTS to try to climb. Or I take a sharper banked turn and do the equivalent of a car skidding out. Or I do a flip and no matter how much I push the stick coming out of it, it just slowly wobbles down to the ground and taps it before recovering.

Is this just a 1S vs 2S problem? (I find it unruly on 2S). Is there some PID tuning or rate tuning you’d recommend at altitude? Should I just upgrade to a better quad?

Thank you!

I used to fly helis too lol still want to when I get the time but yeah they are different animals.

On my limited knowledge of helis I remember most of the tuning was on the tx. That is not the case with kwads. You need to plug into betaflight and adjust your pids. It's a skill on it's own.

The problems you describe with your kwad sounds like it's more an issue with weak battery/motors as that's why the tinyhawks are considered beginner kwads.

Possibly a 2s battery could help, or my suggestion. Get a real kwad: a 5 inch with 4s or 6s battery. No loss of power with either lol.

Think of it as on a heli you can pitch your props steeper but if your motor battery combo can't handle it you'll hit the ground.

You can't expect 450 power out of a 90 copter.

If you want to stay micro but still have the power, no worries. These psychos have been building 6s 3 inchers lol. The kwad world is WAY more daring than the heli world:

Yah on 2S I like it a lot but takes some messing with the rates to get super rate set higher typically to make the mid stick less touchy and edges still good for fast rotation commands. I've had the same kind of experience flying tiny whoops in terms of wobble out after a roll or flip they are mostly good for angle mode racing indoors I think but with 2S shouldn't have a problem recovering and mine flies pretty solid for a little guy I think:


^ less flippy more race
