Fastphil got me thinking about low HS.. so I wanted to know what rpm we would get on a single 6s with 13.8:1 gearing and a 520 kv motor. I don't think I'll be flying on a single pack!

At no load.. zero pitch spool up the starting rpm was 958. After a 5 minute no load run the final rpm was 930.. The battery was awesome.. starting at 4.20 per and ending at 4.10 per.
Anyway I just had to know for sure. Thought I would share.

Hi Dennis, Thanks for the testing, I have my sights on a new Roban SS and was hoping to power it up also with a single 6s, but I guess with it's gearing, it's a no-go....I am still flying my 700-size TRex with the Hughes fuselage on a single 6s, and my brother has just about the same set-up except for the motor, and after a day of testing, his would only fly with two 6s....my heli has a Super Power-size motor...Thanks again for the test!

Super Power-size motor..
Do tell.. what is it?

Well I finally flew my mechs today as a 2 blade. I used brand new 5000 mah packs and was amazed!! I got two 5 minute flights and came down with 3.80 per cell after the flights. My highest power out reading was 78.0% @ 1400 rpm. The esc high temp was 132.0F, the lowest voltage was 45.0 at the very end of the second flight. Mostly in hover, very little FF so it will use more voltage. I think I can live with that.
