My recommendation would be to try somewhere in the 2600-2800. Just my 2cents.

So if you starting then drop it to 2600 and use wooden blades. This will save you $$$ in crashes. But which 450 are you using ?

If you are a beginner maybe stick with the plastic blades at least it won't crack with a minor tip over. Beginners shouldnt be over a foot off the ground anyways. Polo

If you mean a total beginner e.g. learning to hover then 2500 will be plenty.

Ide recommend gearing the motor down instead of using low throttle curves as things will run cooler.

Add an extra set of flybar weights for extra stability.

60% of the time, it works every time!

It will feel more stable at a higher hs.. 2600 to 2800.. If you can buy cheap carbon/fiber blades I would recommend the higher speed.

There are a bunch of 450 models.
The SEv2 and Pro have thrust bearings in the head and tolerate the high speed stuff better.

The C rating will make a difference too. A lower C rating will calm it down as well. Just don't go below 20C.

20C - low performance

25C - Medium performance

30C - 3D

If a total beginner it is good to have someone with experience set up dual rates and expo. Over steering is common for beginners. It couldn't hurt to have the same person check the setup to make sure it isn't hard to handle due to slop, etc. It can be hard to recognize what is and isn't normal when learning.
