It was great while it lasted. The jump from the 9t to the 11t was like a dream come true. The HBK2 went from a docile, bobbing leaf-in-the-wind, that cringed and bogged at the thought of a punch-out, to a fierce performance machine that did everything I asked and begged for more. But it was too good to last. The strain on my batteries was too much and I fear that I may have shortened their life. Even after reducing my flight times, packs were pretty warm at the end. I was down to 6 minute flight times and the packs had between 10% and 15% left. Even reducing my throttle curve down to 80% didn’t really seem to help much. The batteries are rated at 15c and with the Esky 3800 that might be too much when pushed with a larger pinion.

I loved the change in the heli so much, I contemplated upgrading to all 25c packs. But that’s a big expense and the smaller pinion was already in stock. So it’s back to the 10t for now, which is no were near as pokey as the 9t, but it’s not the hot red headed 11t I dream about.

I use 11T with JGF motor. I'm just a noob too. it can fight the wind thought. I need to remember to get 10T so I can tame it a little bit.

10t rocks align pinion turned upside down of course with a grub screw for me.

and turn midstick up to 85% throttle with no expo that'll turn her into an auburn beauty greggor.

Tryan, yup, throttle curve hits 85% by mid stick and the 10t is quite nice compared to the 9t. I'm using expo the throttle curve so there are no abrupt changes. Current resultant settings for normal are:

00 50 85 97 100

Its been snowing here so I haven't been able to try it outside yet. In the garage and the living room it feels pretty good. Just not quite the same as the 11t.

Pinion puller. I wanted to get the Extreme PP but haven't got around to ordering it. I thought about leaving the 11t on until the PP arrived, but was concerned about what it might be doing to the batteries. I've also be deliquent on ordering the IR temp gauge so its hard to get a good assement of the batteries tempature at the end of of a flight. Not wanting to wait, I made do with what I had around the garage. I used some needle nose pliers to grasp the pinion on the shaft, just below the teeth (motor hanging) Then I put the pliers against a vice for support and held it ther with my left hand. With my right hand I supported and old drill bit on the tip of the motor shaft while my wife tapped the end of the bit. She caught the motor when it fell out of the pinion.

A couple NOOB WARNINGS on contents of this thread:
1) If you are just starting out, 9t is safer and since its less responsive, will help dampen pilot input until the thumbs get more steady.

2) Higher headspeeds are more demanding of a perfect setup in the head. At the higher headspeeds, vibrations that are small now, might get much worse. A small blade tracking issue could turn into a big blade tracking issue. Damaged wood blades may get thrown from the blade grips. Loose or non-thread lock bolts are more prone to coming out.

3) With my throttle curve, if you pull back the left stick in case of emergency, the motor will still be recieving power as the blade go into negative pitch (50% throttle at 1/4 stick). This has the potential to slam the heli into the ground if the left stick movement is not done in controlled manner.
