My first Quadcopter build

Originally posted by B1RDY I am a little unsure as to the proceedure of connecting directly to the Rx.

The throttle is on the output marked CH3 on most systems. Just connect them one at a time. Look in the manual first to see if there is a special procedure to do them all at the same time on the Gaui.

Originally posted by B1RDY I have several problems; 1. Props are slipping, I have a nut under the prop in the nut recess and a nut in the top recess with a spring washer on top of that with a nylon lock nut to finish it off. 2. Some of the circlips on the bottom of my motors are coming off, not sure if this is just poor quality motors or something else. 3. Trimming the quad, my battery needs a better mount to keep it secure and in the same place, I am working on a solution but ideas are hard to come by. 4. Still having problems getting all the motors to start up together, as you can see from the videos.

1. Never had a problem with that, not even with my cheapest motors. Maybe that is because I've never used CCW + CW rotating props, that could be ofcourse. First nut till the end of the thread, prop on top, washer on top and then finally the last nut. The last nut needs to have some kind of locking, either it's a nut with plastic inside, or you have to use good threadlock.

2. That is not good. It sounds like there maybe to much pressure on the axel. Or maybe a bad bearing, I don't really know what the downside of your motor looks like.
Maybe you could post some pictures.

3. Dubble sided velcro is your friend!! Two straps per lipo, problem solved.

4. If you've calibrated every single ESC and you still have that problem, then it could be that you have a faulty motor or ESC. (or several bad ones for that matter)
In the video, it looks like your motors are stopping because they are not turning well. Have you checked if the motors are turning smoothly?
Also check for bad bearings.
If it's not a motors problem, it's probably an ESC problem.
You could try to play around with end points on your Tx, maybe they don't have the right range.

I use nylstop nuts ans i put two on each axle, that's enough for my tri and quads.

Hi! You have to re-program all esc separately first.
Reduce the travel to 50%, and set your radio with at least 35% expo.
For the battery, velcro bands are a good solution ( as I do myself!).
For the vibrations: i use adhesive foam (HK)ans it is right enough if you have good props well balanced.
Mines are flying quite good.
Good luck!

Thankyou for that information I am going to try this tomorrow and see if it works.
