Yep, I think he means the HS for the Trex. 1800 or so would be better but sounds like you are at the gearing limit. You could dial it down some, but you could loss eff.

What you need is some flat bottom blades or at least semi's....not sure where you would find them in the 600-610mm range, but that should get you a few more minutes on top of what you're getting even now!

QR,

On a side note, how are those DS821's with stock arms working out? I have the same setup on my new 600 (one 4 minute hover to date).

I have no major complaints, but then I don't do extreme flying, where it really matters what servos are being used. At this point I don't have any rational reason for spending and additional $225 for the 'good ones' with the type of flying I'm doing...

That's a good idea! But now we can't accuse you of having a screw loose.

If you're doing loops and rolls at 12 pounds, that's extreme enough to impress me. The 821's are awesome servos, despite an undeserved bad rep on the otheRR forum. I have yet to see someone over there pin down a REAL, factual instance of failure. They are plenty for a 600 size heli, esp. if you use 6 volts.

Bit of a misunderstanding. I own two ships, the Airwolf is using Futaba S3151 for cyclic(the good ones) and my A/P Trex 600 is using the 821's for cyclic. I can't say how the 821's would handle the paces I put my 12lb Airwolf through.
