Head speeds with Scorpion 2520-1360

[Foqr]

What head speeds are you guys running with the 2520-1360? When I do the math I get a max of 3500 rpms with the stock 16t pinion. I plan on running a governor, so I will loose about 10% Putting me at around 3150, or 3200 rpms? I am thinking of going with the 17T Pinion. Which should put me at around 3450 rpms governed. What would this do to flight times, and do I need the extra 300 rpms?

I'm running 2500, 2800 and 3200 modes if I remember correctly. It's crazy on 3200 already, don't feel the need to go higher myself.

PS thats with SK540 gov via yge60. Flight times around 4 mins on one year old Gens 1400.

3100-3200 is what i feel is the best for this motor.

What pinion are you running on yours?

[crf69]

17t 19t tail pulley

Am I right side up or upside down?

Nice
I'm still on stock setup, don't want to hurt flight times

If the 16T does not tickle your fancy, then step up to the 17T pinion. With a castle ESC you can get like 3250 max I believe. That was my setup for hundreds of flights before my conversion.

Flight times dont diminish too much, maybe 20 seconds if that.

16T still works for me, but on the higher HS, i'm out of optimal HS for the gov. At 83% TC on YEP gov, i see some HS sag after 2 minutes flying on hard moves.
But it's OK for now, as a low HS flier, stock setup is the way to go to keep all the grunt (57% TC)
