Update on the Blade CP parts experiment:
The Plastic CP Pro replaement blades weighed in at 15.9g compared to the factory Blades weighing in at 14.2g. The factory Axe Paddles weigh 2.2g and the Blade paddles weigh 3.9g. I increased the rotor pitch by one full rotation on the linkages in an effort to generate more lift at the same head speed and compensate for the shorter narrower blades. The results were the same as before. Just not a functional combination. I'm going to try the Blade CP Paddles with the stock blades today. I am guessing that the heavier weight and smaller surface area will make them less responsive. If it doesn't work well with the Blade paddles, I am going to drill a hole in the Axe paddles for a scew/nut locking system like the blade paddles and see if it is not a bit more durable.
So is that correct, there really isnt a charger for these Great Planes LiPo 11.1V 910mAh 3S 15C batterys for under $150? Whats DC mean, i can charge it off my car Battery? Also will that power supply work with "Great Planes LiPo 11.1V 910mAh 3S 15C Discharge Deans & a Great Planes PolyCharge Lithium Polymer DC Charger"

THANKS!!!
This charger is probably the best bet for cost savings. Between this and the power supply I provided the link for, you will into this for about $75.. http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXHNW5&P=M D.C. stands for Direct Current. The power supply converts your household 110 V. A.C. (alternating current) to the D.C 12v. needed to run the charger. Very simple set up that works well. and IMO is pretty cheap..

Ok cool i already have this charger/battery on the way from Tower. So that " Pyramid PS-14KX Regulated 12V 14Amp Power Supply" you showed me in the link will work for sure with the "Great Planes LiPo 11.1V 910mAh 3S 15C Discharge Deans & a Great Planes PolyCharge Lithium Polymer DC Charger"? Just making sure. This battery stuff adds up quick, and i went the cheap route

Yes that power supply will work fine for your needs. Now you don't have to use your car battery and can charge the Lipo up in your warm house. lol..

haha thanks for the quick replys, you must be busy at work also The charger says "250 and 500 and 1000mA selectable charge current" which should i charge that LiPo @? Do i need any special connector to connect the charger to the power supply?

heheheh. yes I am work, and the college I work for has not started yet so I do have some free time.
You''ll have to see what they give you for leads with the power supply ( if they give you any at all). If they don't give any, just get some banana plugs with a lead on each. Strip one end end to expose the wire and clip the alligator clip that is on your charger to the banana plug lead. WHALA! Charge to your hearts content.
As far as the Mah charge rate setting on the Great Planes charger I am not sure. Maybe someone that has this set up can chime in on what you are supposed charge the Lipo at. I am also interested to know what the setting should be as this is the route I will be going too. Good Luck and let us know what your outcome is.

I believe from what has been said on here it would be best to do it at 500, from that rate you get a better charge than at 1000. The slower the better.

LiPo's charge rate is the same as the capacity of battery. For 910mA the max safe charge rate is 910mA. You would have to use the 500mA setting as the 1000mA is too high for the battery on that charger.

I need some help here...
I just replaced my blades and blade grips tonight (repairs from my last crash), and the blades were balanced very nearly perfectly dynamically and statically right out of the package. I installed the parts and fired the heli up to track the blades. At first, the blade I marked was high. I fixed it, then started inputting left/right and fore/aft cyclic while the heli was still sitting on the ground. As I was spooling down, the heli started wobbling side to side just below 1/4 throttle. I took the head off and the spur gear off, pulled out the shaft and rolled it on the countertop (I thought I could see the button moving at slower speeds as if the shaft was bent, but I might just be seeing things), and it was straight as near as I could tell. I re-assembled everything and tried to track the blades again. I got them tracked okay and input more cyclic. Guess what? Yep, tracking was off again.
I tried rotating the blade grips, and one made sort of a popping sound as I turned it back and forth. I pulled off the pitch control linkage (I think that's what it's called, the linkage that attaches to the blade grips to the seesaw), I could wiggle them back and forth (in the direction of the screw in the middle), and I could pull them apart by hand! I could screw them back together again, but the threads inside one of the ball links are effectively stripped out.
I'm most certain that this is causing the blade-tracking issues, but can it also be the source of the side to side vibrations? When the vibration occurs, it only happens just under 1/4 throttle and it happens when the blades are both speeding up and slowing down. If I go to my LHS to pick up parts, (they have Blade CP parts) would the linkage set for the Blade CP in the picture below work? Here's a link to the part:
No the linkage set for the Blade has a smaller ball stud. I stripped out one of my linkages too and picked up the Blade parts just to find out that the didn't work. So I had to order a set from Tower.
