I haven't done the main motor mod yet, but here is a pic of my mod. I got all the parts I needed, including the spade connectors at the local car stereo shop. They were like what are you using this for anyways, I said an RC heli. They were pretty impressed and talked to me about it for a few min.

I use a 7.5A for the main and a 3A for the tail, although a 2A on the tail might be better. Som people just solder it in, so that there is less chance for failure, but I like the quick disconnect because I can change it out at the feild, and usually I don't have the ability to run a soldering iron where I fly... I have a pdf on it written by SSG Scott... if you want it PM me with your e-mail and I'll send it to you

Whatever you do... do not put the resistor that alot of people talk about in-line with the fuse and tail motor. If you want to know why I can explain it... but it's just a bad idea that's been implaced by people who don't know enough about electronics.

I would move it in about 2 holes. All you need to do is make sure that your swash doesn't bind. You may have to turn down the servo linkages and make them shorter (like 1/2 to 1 turn... do all of them the same amount).

You can also add super skids for a lower CG which makes it so the heli balances a bit better. www.super-skids.com
