Walkera G001 Gyro board closeup pics

Here are some closeup shots of the walkera gyro board requested by another member. I had one apart so i took a few closeup shots of it.

Shot with a canon powershot S2 using the stock flash in super macro mode with a paper/cardboard flashring. ISO 50, F5.0, 1/500 shutter, max flash manual mode. Cropped with MS paint for file size.

Here is what I was looking for :

See in the lower left side of the board, next to the inter board connector pins. There is a capacitor, resistor and empty pads for something ? I amhoping a resistor goes there. A cap would be difficult to guess and I'm sure Walkera wouldn't answer, they rarely do.
This is a different board than Bower's. It is a G006.
Thanx Bower.

I made another blog entry with some idea of what im using and the cardboard flashring setup. I think one can be built for a smaller pocket camera, i never really tried. I probobly should sometime.

I think this gyro will only be good for rate mode, or some goofy experiment. X the HH mode. The rate mode piro rate is like a snail, my old Walkera 4 has more piro than I can get with this cheapo.

I dono, like i said i liked the 006 in rate mode when i had one. It flew really good. I wouldnt mind having another one

If you notice how that sensor is mounted in foam in the center of the board. Is yours square with the case?

I moved mine on a couple of my helis. I put it on the top of the board and then i mounted the gyro on its side up under the boom.

I did think about flipping the sensor. I'll just use it on a docile rate mode heli.
I've been working up the stuff for a King V2 I am getting. The problem is, I was supposed to gut the belt tail CP2 to build the King, but after flying it a few more times, just can't shoot a horse that can run.
I guess it's gonna be a whole new heli, servos, gyro, AR6000, and set of lipos. I may back out and continue to fly the CP2 on old 3 cell lipos that are too weak to fly the 400's. I cut them down to two cells and the CP2 , specially configured for 2 cells, has as much or more climb rate as the 400's on new lipos, and it can easily fly 10 minutes. I limit it to 9 for safety. 2 cell helis can be a trick for the BEC because there is not much voltage margin on a 2 cell system. You can get to 3v/cell on a 3 cell and the BEC has plenty of reserve. Down to 3v/cell on a 2 cell and it's a gamble as to the BEC having enough input level to power the radio/servos etc.

I have a 450 on a 2200 2S pack and it flys awsome. Its one of my favorite slow flying helicopters. I put those 325mm flat bottom plastic blades on it and i fly it around every now and then. Ive never had a problem with the bec not having the right voltage.

I usualy fly a 6EX radio and the esky 6ch king receivers. I dont think they have issues with low voltage like the newer radios do.

There is a thing called dropout voltage that BEC's have. Below the dropout voltage , operation can be unpredictable, like turning off/on or unstable output. Be careful, it can sneak up on you, especially when very low on the battery and you jam full up collective.
I think the becs I saw work 6 or 6.5v up to 4 or 5 cell lipos.
And so far, by the old (new ?) break the old 3 cells into 2 cells technique, I got just at 550 flights in that I otherwise wouldn't have. Beats making lipo explosion videos.
