hi Ron
youve made the right choice with the master cp, its a good one to start on, i have just bought the V120D02s which is much the same but with a few extras and my flying has come on so much since because of how stable it is
ive been flying for about a year with my 250/300/ and recently a 450 and i lack abit of confidence because i cant always afford the repairs lol, but saying that im fairly competent now and have got to the stage where i can face all directions during flight which is the key, the hardest thing is nose in flight and believe me its a thrill when you actually do it
if you watched the vids your already half way there, the rest is practice
im still learning myself and each time i fly, i always go through basic movements in each direction (like warming up) it gives me a chance just to quickly check that the heli is still setup ok and doing what it should
one piece of good advice i can give one learner to another is take time to learn and understand the setup process and also what the transmitter can do to help you, tony's vids are really valuable here, you may know this already but if you go into the settings of the transmitter and go to dr/expo you can adjust how far the swashplate travels and how sensitive the controls will be while flying
the DR is the amount of travel the swashplate has, to explain turn on the dx7 go to dr/expo and then select DR you should now be able to change the values from 100-0, with two positions selected by the matching switch on the top of the tx, if you select position 1 and then reduce the value down to about 80% on elevator/aileron/and rudder, then unplug two wires from the motor and then power the heli up, you should now see the if you push the elevator full forward and then switch the elevator switch to position 1 the swashplate will raise slightly meaning there is less overall movement making the heli less jumpy, the same for each other direction inc rudder
the expo is the sensitivity of the sticks, they should be at "line" or "inhibit" as standard but if you then change the value to + and a number ( i usually set to +40) you should find that the speed at which the heli now moves in each direction should be slower and less twitchy, the higher the number in the + range means the less twitchy the heli becomes and its the opposite in the negative range
i usually set position 0 at 100% DR and +20-+40 expo, and then in position 1 i have 60-80% DR (depending on how agile the heli is) and again about 40% expo, i have found this helps to get used to flying in a more controlled manner but the option to switch for more attitude is there at a flick of a switch and also for when its windy and you need abit more punch from the controls to combat gusts and drifting
sorry this is abit of a read but it might help
