4000rpm is possible but you would wear things out very quickly and start to see failures at the tail end.

The lower the HS and/or the bigger the pack capacity the more flight time. I think governing to 3000 providing you don't over gear it would give you the best power to flight time ratio.

60% of the time, it works every time!

still waiting for some bits to arrive to complete, I set up the ESC governor last night * castle talon 35
the lowest HS it will govern 2750 and the max if I remember correctly was 3600.

hoping 3000 hs and a 11.5:1 gear ratio will get me 5-6 min won't know till saturday

It should get you 5-6 minutes sport flying and mild 3D but that setup still has too much overhead which will cause tail problems and big current bursts which may shut down a 35 amp ESC. The tail will be your biggest problem though unless you run no more than about 11 degrees of pitch.

Flight report
Finally got a chance to maiden it today and it left a grin on my face

5 min flights @ 3200 head speed
I have mine set for N 2800, F1 3000, F2 3200 H 0
using a castle talon 35 esc
3400 kv 450mx motor
4S 1800 50C

I had to add weight to nose for cg so a 4s2200 could work out better for me for flight times.
haven't tried timing 2800HS yet I was having too much fun at 3200hs

everything returns to earth at minimal temps

flight report #2
got another 3 flights in before dark

3000 hs seems to be the sweet spot. I tried 2800, 3000 3200 and for me after a 5 min flight I put back 950-1000mah into a 1800mah
about 200mah/minute or a nano cpx lipo/minute

I am using 3 great hobby 50c lipos if I keep my flights to 5 minutes they should last a while.
hoping that ~40 amp [800mahx50c] reserve will help battery life
The next set of lipos will be 2200's, 8min flights for this rocket.
