Status: offline 		The setup for the gyro that came with my bird said to increase the gyro gain (clockwise) until the tail just started to oscillate then decrease until it stops. Have you already tried decreasing the gain? Just a thought.

Status: offline 		I finally received my new motor and its the same wrong $%^&$ motor I got the first time. I think it came from the same company, different name but same city. I think I will order from the place you used on ebay. This is really aggravating since I roached the stock motor and can't even use it for tweaking. Crud.

Status: offline 		Jim, sorry about the motor. The guy I bought mine from was Taiwan and I had the motor in 3 days. It was unbelievable. I didn't even expedite the postage. I really do love the motor and ESC. Neither get hot at all with the 11T pinion. Although I have been thinking of moving to a 13T, just to try it.

Thanks for the tip on the tail. I'm going to go try it...

Status: offline 		Jim, - write that tip in your book! It worked like a charm! I backed my gain down to about 65% from 80% and the tail wag stopped! I think the wag must be because my new servos are so much more responsive than the old Walkera NS-05's.

Actually, speaking of those servo's, they are extremely responsive. It's going to take me a little bit to get used to them. I've only done some hovering in my house since the change over but every tiny stick input is immediate. No lag at all. Hopefully that will help rather than hurt my piloting skills.

I've now got the gray align RC tail boom and the new clear blue servos. The bird is starting to look different all the time. I also put my training gear back on as I want to start learning nose-in hovering.

Again, thanks Jim and sorry about your motor!

Status: offline 		I'm glad that worked Mike. Did you get the seperate sheet of instructions on the WK-G006 with your original manual? If not I can scan mine and email it. I didn't see it on the Walkera web sight and it has some pretty good info. I really like the looks of that motor/ESC setup but I already installed the 30 amp ESC that came with the original order. On the outrunner motors the entire exposed motor casing spins. The only thing stationary is the mounting plate at the front of the motor where the wires exit. Does your housing spin, it didn't look like it. I was worried about chafing the wires from the lipo which is very close to the motor. I think I will just order your setup and have a spare ESC. He does not appear to sell the motor alone.

Status: offline 		I'll bet you get it quick, if it's anything like mine. He was selling just the motor when I purchased mine, but maybe he's only doing combo's now. Anyway, I was checking the pinion on my motor tonight and apparently I've been running a 10T not an 11T. I took it off and put my 11T on but haven't had a chance to fly it yet. I thought I had been running an 11T all this time and was planning to put a 13 on tonight but I don't have one.

You'll need a pinion for your new motor and the Align 3 packs work great. I have the 9, 10, 11 pack. I'll let you know tomorrow how the 11 runs...

Status: offline 		Hope so. I already have the pinion set so should be good to go once I GET A MOTOR. I'm leaving for a solo bike trim up the CA coast a week from Monday so hopefully I will get a chance to try it before then.

Status: offline 		Actually the manuals says setting gyro sensitivity high will cause over compensation in AVCS mode. That's why you had tail wagging.
I have me Gyro on normal, for know I dont fly in parks.. until I become an expert. If you set more than 85%, your asking for trouble.

Once I feel confident enough, I will swtich back to AVCS mode to fly outdoors.

Status: offline 		It seems to fly fine with the 11T on. I didn't notice much of a difference either way. I did the calculation for head speed and I'm running about 225 rpm's higher with the 11T than the 10T. My headspeed with an 85% efficiency should be somewhere around 2600 right now. I read somewhere that 2800 is best for 3D but since I'm not doing 3D, I think 2600 should be fine. I had two good flights in today so I'm happy . It's nice to have it all back together and working well. I brought it to work today and our plant engineer has decided to go buy one tomorrow night. He wants a Blade CP because our LHS supports them and he likes the thought of being able to run up to the store to pick up parts. I can't blame him there! Anyone have a Blade CP? If you do, should I steer him away from them? I don't know much about that aircraft so I can't say. I figure they can't be much worse than anything else out there.

Status: offline 		Mark I think you are right. I received email this morning (7:00 am) that the order had already been shipped. If I get this stuff by mid next week I will have plenty of time to get it back in the air before my bike trip. Thanks for the advice. I was going to start with the 11T since that is the stock gear. I also ordered a 1800 10C lipo battery for and backup. This 2200 12C is pretty big. I touches the front of the canopy and clears the motor by about 1/2 inch. Maybe I will dedicate that to my airplane. Glad to hear your bird is in shape.
