gjeffers...

I'm at 4800'. But one field I've recently been flying at is 5200'.

Yes, you won't believe how much power you lose. You'll have to learn to fly all over again. And it's not just engine power it's thrust efficiency with the prop and lift. All of that adds up to about 30% loss in performance. That being said...If you watch your weight and put the right engines on you'll still have a blast.

Welcome back.

Thanks
