No kidding, thanks airaptor, I didn't think it could handle it, according to what the instructions said. I was also thinking about trying the eflite BL 15 DF 3600kv motor on a prop, on 4s.
CP this thing makes my F-20 look like a trainer in the air.[:-]
rv4,
You may want to try the HET 2W-23 Like Mike Conner is using. This motor will take a 4 cell (no problem) and up to a 5 cell if you watch the throttle according to their specs, (you are talking around 48K max RPM).
Airraptor is right about the air you keep them cool enough and you can push them harder than spec, heat (and high rpm) are your two major issues. One thing I have know for sure with electronics if you keep them cool enough you can sometimes really push them well beyond their specs.
One thing to keep in mind is that keeping things cool also applies to the battery and speed controller as well, you need good airflow past these components when you are doing high power electrics.
