RPMs
RPM around 1050. Not sure about the weight. It is little tail heavy but doesn't bother me. Thanks

I did a conversion from 12s to 6s on a trex600E. Flybarred.
Motor from 510kv to 1100kv.
Stock ratio 8.6

It is very difficult to hover below 1500 rpm.

I don't get it.
Do I miss something?

RPM
Correct me if I am wrong but with an 1100 kv on 6s and 8.6 gear ratio the main blade rpm comes out tobe 2271 on 80 % throttle. That should be more than enough.

Oh! Yes! For sure.
High rpm no problem!
I fly at 1800 rpm that bird.

I mean... when a I try to hover at low speed, hover is very difficult.
There is something that I don't take into consideration, I presume.

Rojoalfa hover is very difficult
How do you mean difficult?
60% of the time, it works every time!

Well.. Please, let us verify the criteria...

LHS means Low Head Speed.
For me, LHS is from 900 to 1500 rpm.

There is other considerations that I would like to know.

My trex600E with 6s, flybarred, is very difficult to hover and recuperate below 1500...
