I finally got around to checking the amp draw and head speed on my XL today. I get around 2100 RPM max with 315 woodies and TP 2100 Gen 2's. I'm only drawing about 10 amps at hover throttle position (heli weighted to floor). I have no complaints about performance but I'm so used to seeing 2400 RPM being posted as the norm. I tried changing the pitch curve and it didn't help much. I can't imagine it flying any smoother. Should I worry about changing things around to get the RPM up? My only concern is about pack temps after 10 minute hovers. 130-140 degree range. I guess I could just fly a few minutes less but that's no fun.

Duh. Stoopid newbie, I know. Well, all I had to do was change the throttle curve and up went the head speed. It was too simple. I flew 9 minutes with the brand new 2100 ProLite pack and it came down with the battery just barely warm. That's still with the 13T pinion. I may still do a pinion swap to see if there is even more improvement in battery temp. I like it so far.

I think you should try higher head speed but less pitch. This make it more efficient.

I fly my t-rex on 3100rpm... for 3d... But at least 2400-2600 for sport flying.

If i got $, I will run my T-rex on 10s lithium.
