Here it is from amain, You can use the part number to find it else where. http://www.amainhobbies.com/product_...inion-Gear-11T

maybe it's time to look at a new motor. Most guys have found the align 500mx to be equal or better than the scorpion 1600. I have not seen anyone talking about any better motors right now.

For speed with a 12t and full battery no load your looking at 3665, but the calculator I use take into those factors. Under load you could see 3200 and that is what the Align 500pro manual list as well.

My current ESC doesn't have one but the YEP80A I have coming does. I would of course adjust the throttle curve accordingly once it's installed.

by 70-85-100 I mean 70% at zero degrees, 85% at +/- 5.5 degrees and 100 at +/- 11 degrees.

I've not seen the Trex 500 Pro manual, but all their other manuals seem to show headspeed right at the start of the battery.

For example, you would need 4.2v per cell, and 100% of the motor rpm with no reduction for any load to get 3665 with a 12t / 132t setup.

Realistically, even at zero pitch, you will only get about 90% of the theoretical motor rpm, and that will drop under load at high or low collective, or with tail inputs, especially right tail. So I would estimate zero pitch HS ranging from 3150 at the start of the battery to 2900 at the end, if using a flat 100% throttle curve, and loaded headspeed to be about 2800 dropping to 2600.

Maybe I just use crappy battery packs, but my flight data logs seem to show a loaded voltage per cell of about 4v dropping to 3.7v.

Sorry for the off topic guys...

Do you still get buddy codes from an item from HK when you use the discounted offer window? ie when you leave the item page open log enough you get the discount window

edit// totally read that wrong..... YES you get the code as long as it is a eligible item lol

you dont get a code to share if you use a buddy code to buy the item.

assuming you checked the main shaft already, it could be imballanced tail blades/grips, maybe the tail shaft itself is not true. Also check for bad bearings in the tail section, starting at the boom case and working your way back to the tail case and grips.

If its fbl, then lower the elev gyro gain....

Mine did that on my HK and the airwolf. Both turned out to be play in the swash. Could be excessive play in the links as well.

Well....I learned today that there is a diff. in 450 motor pinions..Needed 3.5 mm and bought 3mm. That was a waste of 8 bucks. ha...( anybody need 3mm ? )

On the bright side of things I am now doing and holding inverted flights now between 10-15 seconds with a few Pirouettes included on my 500 and 600 helis. Next i just need to bring all my newly learned tricks closer to the ground. ( dirt naps need not apply)
