Any experience on 800 blades (or 790) with FBL?
RPMs for aero/hover?

Just a little input..

Only have experience with the Goblin 770 SAB blades so far. In spite of the 'low' weight of 240g they work very good.
Approx 1250 in hover and 1930 upstairs.

No problem to do the 2014 P schedule on 12S 5000mAh.

After 4 years of flybar F3C I was quite shocked how quick FBL starts to feel 'good' in F3C.
Considering how well hovering feels at this low headspeed, I really doubt the claimed 'faster response' of 3blade heads makes any sense for pilots on my level.

I am sure 275-300g would feel even better in hover, but I am also sure power consumption increases upstairs.
For F3N I tried the awesome Radix 710V2 FAI. For set manouvres they work great, but power consumption increases. For freestyle it becomes very clear that such heavy blades really increase load on the drivetrain.

The KDS EBar V2 might not be very 'known', but it has impressed me alot for F3N. In F3C, if you increase 'Motion' to 100% and 'Flybar feel' to 50 you actually get a very nice F3C feel.
It's main problem is maybe that it is too cheap to be taken seriously :-)

I flew (and setup) my friends stretched Sylphide with JR795mm blades, about 290gm

Hover felt good at 1250RPM, too soft below 1200.
Upstairs was very sharp and FAST at 1700RPM.

It auto FOR------E----------VER!!!!!!!!!!!

i ordered NHP800 for a first test now.
I cant get the JR795 locally, i would have to order from RC Japan at roughly 350$ landing price here including tax (estimated) and that is a bit harsh for a test.

They should be there tomorrow.

They have only 61mm depth compared to the GFK i use now who have 68.
Weight is 230g

I had NHP710 on the TDNT and remember that it was the most neutral one on that machine.

We have storms here with force up to 10-11 so flying will not be possible.
