Great explantion regarding building your own Quad. Was going to buy RTF but slowly changing my mind after watching your vids. As a complete noob to Quads i understood your build but could you explain please when you mention PI gain and these reccomended numbers you give, what does this mean regarding setting up your quad before your first flight . what exactly does gain mean.

Hi all..just wondering if anyone can tell me how to turn on auto level. No switch will turn it on. Tx is Spektrum DX6i. Do I need to assign this chanel to a switch? What am I missing here?

Ox5,

Are you using the kk2 board?

If so then you need to, first, configure your Tx to bind a switch to channel 5/aux1. This is often used for the landing gear, so you might find documentation on that.

Secondly you need to make sure that you have a jumper/servo cable from channel 5/aux 1 on the Rx to the fifth channel on the kk2.

You then need to modify the setting for self-level in mode or misc settings to aux, the other option is stick.

You can also activate self level with the sticks. Throttle down and to the left, elevator down and to the right.

because that's what I've gathered from reading forums and my own tests. 8x4DD gws props feel way different compared to 8x4SF

Self level is the helicopter wanting to level itself when you release the controlls. Works sometimes and not so well other times. I like it because it seems to make the helicopter easier to handle more stable. But I'm a low and slow type.

You said "these are designed to create more drag and reduce rpm". This is just plain silly. So called Slow Fly (SF) props are thinner and create far less drag than standard props which makes SF props far more efficient.

SF props were initially developed to do exactly the opposite of what you said. They are intended for early electric power systems that were not as powerful and had less vibration than glow engines. Therefore SF props could have smaller and lighter hubs because the potential for them to fly apart was far less in an electric motor plane. Lighter weight, less mass, more efficient.

Look at these three prop performance charts.

10x7SF for low power electric motors

10x7E for high power electric motors

10x7 standard for glow engines

I use a jumper wire on the 5th channel of my Rx to the 5th channel on the KK2. I activate the self level using the gear switch on my DX6i. Or you can activate by using the sticks on the TX. Throttle full down and to the left and elevator full back and to the right. It will show self level on the LCD screen. Set your choice of stick method or switch on the KK2 menu.

I have the HobbyKing Multi-Rotor Control Board V3.0 (Atmega328 PA). It is very similar to all the kk boards, but I don't have the LCD screen. Anyone know how to do this on my board? I cant find a manual for it.

Thanks, I looked there and it wasn't there. Apparently because I bought it from the USA store. The file is only under the "International Store" files tab.
