If it flips on take off one or more of the motors/props is going the wrong direction or connected to the wrong input.
1. Take the props off and place an inch long piece of masking tape on each motor shaft.
2. power up the board and go to the motor layout screen. the correct rotation for each motor will be shown. Write this down. Close the menu and arm the quad bring the throttle up and watch the motors one by one. If it is not turning in the correct direction reverse two wires between the ESC and the motor. Recheck rotation.
3. When all the motors are turning in the correct direction and with the props still off. Arm the quad and pick it up hold it level. If you do this with the props on you are on your own. Bring the throttle up to half, All motors should start at the same time and be turning at the same speed. Tilt the quad forward and the forward motors should speed up. Tilt it back and the back motors should speed up. Do the same for left and right. If all of this checks out it is time to disconnect the battery and put the props back on.
4. make sure the prop is pitched up in the direction that the motor turns.
All the props should have the writing up. Each adjacent prop will have the reverse pitch. Arm and it should fly. If not place on a level surface and calibrate the sensors in the board. Good luck. Don't fly too high (1 meter) until you get the gains set for your quad.

Props/motors must be backwards. They are pushing air up instead of down. Double check the motor direction and the prop pitch. The leading edge of the prop going forward will be higher than the edge at the back. Easy mistake

Sounds like someone is extremely new to the RC and quads....

The 1045 is the prop size......10" diameter 4.5 degrees of pitch.

The R represents reversed....you should have two with an R and two without......

The CW...CCW represents the material they are made of....some kind of carbon fiber/poly blend.

Your air craft manual should state which two (R) props are mounted where.......stock, the prop sizes are generally 8x4.5.......wonder why yours are much larger....?

If this is an ARF or semi scratch build.....best advice anyone can give a newbee for quad (or any RC) info is to seek the help of an experienced quad guy in person...hands on. Your in for a very long and frustrating experience otherwise......RC forums will only take you as far as your ability and understanding grows, which could end up doing more harm than good.....

This thread really needs to be dealt with in the Multi-Rotor section....not flight sims.....

You sure cw does not stand for clockwise and ccw stand for counter clockwise

Yes, CW relates to the "clockwise" rotation and CCW relates to the "counter clockwise" rotation direction each of the motors turn with multi-rotor props......the "material" aspect was related to CW "consistant weave" or "carbon weave" referred to by many related to carbon fiber material used in automotive and aircraft industry....my bad, thought CW & CCW were obvious common terms used with multi-rotor spin direction.

Make sure all your radio trims and sub trims are set to zero. Power up the quad enter the menu and move to the receiver test screen. Now you can trim the channels until they show zero. This could be the problem or the channel could be reversed or the acc could need to be calibrated.

After the receiver test, set the quad on something level and calibrate acc. Then power up in a safe area. Bring the throttle up to just before liftoff. Now you are going to check your channel direction. Gently move the stick left and the right motors will speed up. The right side may lift up, just move the stick back and it will settle. Be gentle and check all channels this way. Rudder is not easy to check this way but all the other channels can be checked.

If it flies level now you are ready to start working on the gain settings. If it still goes right add left trim. Lift off a foot or so. If it is still going right add more trim. Repeat

I am assuming that it is moving right sideways and not turning right. Your descriptions of the problems are very sparse. More information would help.

Yes it is moving to the right even if it's no stick input

Have you tried to calibrate the accelerometer? Have you checked the receiver test screen? If yes next check balance point. Your quad may be heavier to the right.fix the imbalance if you can.

Use trim (left trim) to stop the right movement. Do this first with self level off.

Try little hops. Power to lift off use left roll to control drift and notice how much stick input is needed to control drift. Land adjust left trim and take off again, now less stick input should control drift. You repeat this process until it drifts very slowly, not at all or drifts left. Then I use the radio menu to set subtrim for that channel and return the trim lever to center and test again. If this process is doing nothing something else is wrong. If it does work you are getting somewhere.
