probably around 3500rpm.....not sure about the v2,but people at my field are running the "pro" at that rpm and having great success.

i used to run my Flybarless T500 at 3000rpm.....swinging 425mm blades.

Is a HS of 4294rpm too much ?

If I use an 11t pinion I'll be around 3633rpm

I ran my V2 over 3300 for many hundreds of flights on 4S. I could run faster but my tail would act up more at higher headspeeds.

You might not have problems, but I did. I tried some different tail blades and a few different tail servos/gyro combos but I couldn't find anything that worked perfect at very high headspeeds (3400+). It would work, but sometimes the tail would act up and go crazy so I just stuck with slightly lower headspeeds and I didn't have any big problems.

I'm running 3450 rpm @ 89%gov on a Jazz/Neu 1107H2Y motor,11t,Outrage 1800 4s 25c, carbon blades main and tail. The higher rpm was the only to get the tail to act right. 1-1.2 amps back after 5.5 min.
